After many requests, we have decided to release our internal Replay Tool that we use to create our trailers. It allows you to record the movement and actions of multiple characters in the same world. You can use your video recording software of choice to capture these moments for cinematic purposes! It’s also super useful for epic screenshot creation. The tool allows you to be the director of your own Space Engineers film where you can carefully position and time different engineers with their own specific roles. We are extremely excited to see what the community will create with this!

Important: because it’s an internal tool, it has a very basic user interface and required advanced users to be used. We believe this is OK, because most video creators who would want to use it to create epic cinematic Space Engineers videos are advanced users.

There are now Steam trading cards to collect for Space Engineers! Collect a full set of cards to earn items that help you customize your Steam profile including backgrounds and badges.

There are fourteen new decorative blocks for people who want to buy them and support the development of Space Engineers, which are available on the Space Engineers Steam Store page. Within the package you will get following new blocks:

Beds can preserve characters’ inventory and toolbar while they"re offline and keeps them alive as long as there is oxygen available. Is considered to be the same as the Cryo Chamber Block, except oxygen is used from the environment. Space Engineers don’t work from nine to five, they work whenever they’re needed: day or night, during peace and war. But when it’s time to call it a day, every engineer looks forward to resting in these beds.

Standard and Corner Desks can be used as seats, which allow players to sit on the chair attached to it. Combine these blocks to produce various designs and sizes, creativity has no limitation. Whether designing new schematics or charting a fresh course to another world, desks are essential for any engineer looking to get some work done.

Kitchens are purely decorative. The kitchens in Space Engineers come well-equipped and include stunning visual details. Space Engineers overcome challenges everyday when they’re working on new planets or among the stars.

Planters are purely decorative, but they make outer space a bit warmer by housing life in a special glass container. Build your own garden on the space station. Planters not only help to liven up spaces, but the flora housed inside these capsules also remind many engineers of the homes they’ve left behind in order to explore the universe.

Couchescan be used as seats, so take your time to relax and take a break. You don’t need to always run, fly or work, you can enjoy your cozy room and enjoy the view. The last thing anyone would ever call a Space Engineer is ‘couch potato’, but who wouldn’t like to relax after a hard day’s work on this comfy furniture?

Armory and Armory Lockers can be used to decorate interiors and store weapons, ammunition, tools and bottles; both are small storages (400L), where you can keep your equipment. Space Engineers use lockers in order to ensure that keepsakes from home, toiletries and other items are kept safe.

Toiletscan be used as a seat. The latest and greatest interstellar lavatory technology has made many earth dwellers jealous of the facilities enjoyed by Space Engineers.

Toilet Seat that can be used as a seat and is fit for the creator of the legendary Red Ship; most engineers don’t want to get up after ‘taking care of business’.

Industrial Cockpits are used to control your ships. This industrial cockpit in both small and large grid versions will make your creations look much better. Offering unmatched visibility, the industrial cockpit enables engineers to experience stunning vistas while traversing landscapes and space.

Console blocks project blueprints for downscaled ships and stations, as well as display pictograms or customizable text. They are fantastic functional LCD panels where you can project your creations and show them to your friends. The sleek and crystal clear picture offered by this console allows Space Engineers to display designs and other important information.

*Note to modders: When modding the decorative blocks, copy the current settings and then do the change on top of that. The mod will also include the DLC tag:

Keen Software House needs to stay profitable in order to continue development and support of Space Engineers, and to take risks, to invest into experiments that may not pay off in the short term, and to develop innovative concepts.

A:Actually, even this update isn’t paid. The major part of this update (LCD screens, Replay Tool, new music tracks, smaller improvements) is free for everyone. Only the smaller and not mandatory part is paid - Decorative Pack, which you can purchase here.

A: To support future development of Space Engineers and other leading-edge projects we plan to work on at Keen Software House. Players kept asking us for something they could buy to support the development of Space Engineers, and the Decorative Pack is a great option for them.

A: Right after Space Engineers left early access and all hot issues were resolved. Most of the work was done by the Art team, the rest of the developers is working on other long-term updates.

A: We want more people to play Space Engineers, which means we must lower the barrier of entry. When the Space Engineers community grows, everyone benefits from this - more content on Workshop, more mods, more new ideas, more people to play with. This means that all non-mandatory features should be optional, so only those who really want them can pay for them. That’s why we decreased the price of Space Engineers, and made the Decorative Pack an optional purchase.

A: Hehe, if you put it this way, it sounds kind of funny. But the reality is that decorative blocks are low-hanging fruit, not a bottleneck towards those other mentioned future features. Additionally, the decorative pack can bring added profit and make the mentioned things happen.

Looking at our upcoming plans, I can say that we are going to work on another package similar to this one. It’s not a secret that we want to bring you more things you asked for in the past, such as new skins, new weapons, new economy system etc.

From Figure 3 above we can see that the DDRAM controller should have a memory map of 104 bytes (00H to 67H = 68H = 104D), but the location that can be used is only 80 bytes 00H-27H (40 bytes) and 40H-67H (40 bytes); Note that the 28H-3FH address (24 location) is not visible.

LCD connected to this controller will adjust itself to the memory map of this DDRAM controller; each location on the LCD will take 1 DDRAM address on the controller. Because we use 2 × 16 type LCD, the first line of the LCD will take the location of the 00H-0FH addresses and the second line will take the 40H-4FH addresses of the controller DDRAM; so neither the addresses of the 10H-27H on the first line or the addresses of the 50H-67H on the second line on DDRAM is used.

To be able to display a character on the first line of the LCD, we must provide written instructions (80h + DDRAM address where our character is to be displayed on the first line) in the Instruction Register-IR and then followed by writing the ASCII code of the character or address of the character stored on the CGROM or CGRAM on the LCD controller data register, as well as to display characters in the second row we must provide written instructions (C0H + DDRAM address where our character to be displayed on the second line) in the Instructions Register-IR and then followed by writing the ASCII code or address of the character on CGROM or CGRAM on the LCD controller data register.

As mentioned above, to display a character (ASCII) you want to show on the LCD, you need to send the ASCII code to the LCD controller data register-DR. For characters from CGROM and CGRAM we only need to send the address of the character where the character is stored; unlike the character of the ASCII code, we must write the ASCII code of the character we want to display on the LCD controller data register to display it. For special characters stored on CGRAM, one must first save the special character at the CGRAM address (prepared 64 addresses, namely addresses 0–63); A special character with a size of 5 × 8 (5 columns × 8 lines) requires eight consecutive addresses to store it, so the total special characters that can be saved or stored on the CGRAM addresses are only eight (8) characters. To be able to save a special character at the first CGRAM address we must send or write 40H instruction to the Instruction Register-IR followed by writing eight consecutive bytes of the data in the Data Register-DR to save the pattern/image of a special character that you want to display on the LCD [9, 10].

We can easily connect this LCD module (LCD + controller) with MCS51, and we do not need any additional electronic equipment as the interface between MCS51 and it; This is because this LCD works with the TTL logic level voltage—Transistor-Transistor Logic.

Pins 7–14 (8 Pins) of the display function as a channel to transmit either data or instruction with a channel width of 1 byte (D0-D7) between the display and MCS51. In Figure 6, it can be seen that each Pin connected to the data bus (D0-D7) of MCS51 in this case P0 (80h); P0.0-P0.7 MCS-51 connected to D0-D7 of the LCD.

Pins 4–6 are used to control the performance of the display. Pin 4 (Register Select-RS) is in charge of selecting one of the 2 display registers. If RS is given logic 0 then the selected register is the Instruction Register-IR, otherwise, if RS is given logic 1 then the selected register is the Data Register-DR. The implication of this selection is the meaning of the signal sent down through the data bus (D0-D7), if RS = 0, then the signal sent from the MCS-51 to the LCD is an instruction; usually used to configure the LCD, otherwise if RS = 1 then the data sent from the MCS-51 to the LCD (D0-D7) is the data (object or character) you want to display on the LCD. From Figure 6 Pin 4 (RS) is connected to Pin 16 (P3.6/W¯) of MCS-51 with the address (B6H).

Pin 5 (R/W¯)) of the LCD does not appear in Figure 6 is used for read/write operations. If Pin 5 is given logic 1, the operation is a read operation; reading the data from the LCD. Data will be copied from the LCD data register to MCS-51 via the data bus (D0-D7), namely Pins 7–14 of the LCD. Conversely, if Pin 5 is given a voltage with logical 0 then the operation is a write operation; the signal will be sent from the MCS51 to LCD through the LCD Pins (Pins 7–14); The signal sent can be in the form of data or instructions depending on the logic level input to the Register Select-RS Pin, as described above before if RS = 0 then the signal sent is an instruction, vice versa if the RS = 1 then the signal sent/written is the data you want to display. Usually, Pin 5 of the LCD is connected with the power supply GND, because we will never read data from the LCD data register, but only send instructions for the LCD work configuration or the data you want to display on the LCD.

Pin 6 of the LCD (EN¯) is a Pin used to enable the LCD. The LCD will be enabled with the entry of changes in the signal level from high (1) to low (0) on Pin 6. If Pin 6 gets the voltage of logic level either 1 or 0 then the LCD will be disabled; it will only be enabled when there is a change of the voltage level in Pin 6 from high logic level to low logic level for more than 1000 microseconds (1 millisecond), and we can send either instruction or data to processed during that enable time of Pin 6.

Pin 3 and Pin 15 are used to regulate the brightness of the BPL (Back Plane Light). As mentioned above before the LCD operates on the principle of continuing or inhibiting the light passing through it; instead of producing light by itself. The light source comes from LED behind this LCD called BPL. Light brightness from BPL can be set by using a potentiometer or a trimpot. From Figure 6 Pin 3 (VEE) is used to regulate the brightness of BPL (by changing the current that enters BPL by using a potentiometers/a trimpot). While Pin 15 (BPL) is a Pin used for the sink of BPL LED.

4RSRegister selector on the LCD, if RS = 0 then the selected register is an instruction register (the operation to be performed is a write operation/LCD configuration if Pin 5 (R/W¯) is given a logic 0), if RS = 1 then the selected register is a data register; if (R/W¯) = 0 then the operation performed is a data write operation to the LCD, otherwise if (R/W¯) = 1 then the operation performed is a read operation (data will be sent from the LCD to μC (microcontroller); it is usually used to read the busy bit/Busy Flag- BF of the LCD (bit 7/D7).

5(R/W¯)Sets the operating mode, logic 1 for reading operations and logic 0 for write operations, the information read from the LCD to μC is data, while information written to the LCD from μC can be data to be displayed or instructions used to configure the LCD. Usually, this Pin is connected to the GND of the power supply because we will never read data from the LCD but only write instructions to configure it or write data to the LCD register to be displayed.

6Enable¯The LCD is not active when Enable Pin is either 1 or 0 logic. The LCD will be active if there is a change from logic 1 to logic 0; information can be read or written at the time the change occurs.

After crashes or space battles, multiplayer servers end up with a lot of floating debris that has an impact on performance if it is not ground down or collected. Trash removal means here that such laggy debris is automatically deleted from the game. But the catch is, how do we define what "trash" is, while at the same time preventing the game from automatically removing, say, a half welded drone that you are still working on?

Use this panel to define auto trash detection in game terms. For example, you may decide to allow garbage collection of any grid "that is either stationary or linearly moving or accelerating, but not powered and not being controlled by a player, and has fewer blocks than 20", and so on.

fixed planetary or space stations (default: off), stationary floating grids (default: on), linearly moving grids (default: on), accelerating grids (default: on)

Remove old identities (hours): Inactive player identities who do not own any grids are removed after that many hours. Set to zero to disable, this is also the default. Note that if you allow players to join without participating, they can sell their PCU allowance to other players, so switch this option on if you have this issue.

This menu manages admin-owned safe zones, which are useful, for example, to protect a spawn point on a multiplayer server. In contrast to player-built Safe Zones, admin-owned safe zones don"t need an in-world safe zone block, use no power, and do not use up zone chips.

Note: If players have created their own safe zones (using safe zone blocks), these do not appear in the list here and are not meant to be controlled from here.

If Economy is enabled in the world settings, an admin can control how many space credits each player owns and what their reputation among NPC traders is.

To change the account balance how much "money" another player possesses, an admin can select a player name; you will see their current balance. Enter an amount of space credits to add, and click "Change". A positive number will be added and a negative number will be subtracted. You can preview what the final balance will be as well.

You can choose to propagate the reputation to friends and enemies of the faction. Warning: Propagation of positive and negative reputation is not symmetric. Propagating +1000 and then -1000 won"t have a zero sum for friends and foes of the faction, so don"t expect cascading changes to be undone easily.

LCD Panel blocks have only one built-in LCD Surface, but other functional blocks have several LCD surfaces built in, for example Cockpits, Programmable Blocks, Custom Turret Controllers, Button Panels, and so on. All LCD surfaces work the same way, and have the same settings as the freestanding LCD Panel blocks. In constrast to the block variants, built-in LCD surfaces are fixed to their block "as is" and you cannot choose different screen sizes or positions. The advantage of the built-in surfaces is that they do not take up extra block space.

Artificial Horizon -- Cockpit instruments that include an AGL Altimeter in the bottom right, current angular momentum in the bottom left, and Attitude Indicator (angled lines in unit degrees) in the center. Typically only used on mobile grids, not stations.

Tip: If you are looking for an option to display inventory capacity, radar view, planetary maps, hull integrity, and the like, alas these scripts are not available by default. To calculate and display such information, you need a Programmable Block. Advanced players can write custom scripts, and everyone can download community-provided scripts from the Workshop that can be configured to output info from the Programmable Block to an LCD of your choice.

Note: If you select the texture named "Faction" here, you"ll get a generic static "Red Fist" logo, not your own faction logo. To get your faction logo, you want the "Faction icon" script instead.

Second, consider creating your custom image out of Monospace text, using Block Elements as pixels. Here is a great community app that converts any pictures into Block Element text: https://github.com/Whiplash141/Whips-Image-Converter/

Drag the yellow diamond that is on the right side of the dimension shape to a position above the piano so that the dimension lines do not obscure the piano shape.

Visual Script Builder allows you to create Space Engineers scripts with a user interface. You don"t need to know anything about programming. Just enter the name of the block you want to control and choose what to do with it. Chain logic statements together to create complex behaviors.

A large number of Space Engineers players are unable to utilize programming. The scripting documentation is poor, and the in-game editor doesn"t provide any help. Many people are unfamiliar with coding, and C# in Space Engineers doesn"t make for a simple beginner language. There are scripts available on the Steam Workshop, but those rarely work for custom applications.

I developed this tool to let anyone capable of playing Space Engineers write their own custom scripts. I tried to make it as feature-rich as possible while still being easy to use.

Overhauled User Variable logic to be independent of Blocks. Variables added to the Affect buttons, which hides the Block Type, Block Name, and Block Group options when selected. Older saves that use variable logic in the same chunks with block logic will need to be updated. These saves will populate all the same information, but the user must select between Variable and Single/Multiple blocks. Both cannot be applied in the same chunk.

Added Functional Block as the first block in the block list. This represents any block that can be turned on or hacked. It is not recommended to use with Single Block logic type selected. As suggested by /u/sumguy720, it is designed to check if any blocks are being hacked.

Keep in mind that as you create your script, the page is updated automatically. You will not need to "Apply" your logic to add it to the script. As you add logic chunks to the page, those logic chunks are used in the script. Removing them from the page removes them from the script.

In Visual Script Builder, everything is driven by logic chunks. One logic chunk can either check a condition (e.g. If Light X is ON), or apply an action (e.g. Turn Light Y ON). You can insert logic chunks and remove logic chunks at any point in the script. There is no limit to the number of logic chunks you can use. Each logic chunk consists of the logic type, the in-game Space Engineers block it applies to, and the in-game block"s data.

Works just like an IF logic chunk, but must be placed after a DO logic chunk that follows an IF logic chunk. Checks a condition only when the previous IF condition was not met. e.g. IF (a) DO (b) ELSE IF (c) DO (d). When condition a is not met, condition c will be checked. If condition c is met, d will happen. However, if condition a is met, b will happen and c will not be checked.

Performs an action or sets a value only when the previous IF failed. e.g. IF (a) DO (b) ELSE DO (c). When condition a is met, b will be executed and c will not. When condition a is not met, b will not be executed and c will be executed.

Sometimes, certain logic types will not be accessible. The button becomes greyed out depending on previous logic. For example, on the first block, you cannot choose AND because that does not start a logic statement correctly. You cannot choose OR to follow a DO logic chunk. (DO a OR b does not make sense.) ELSE IF and ELSE DO cannot be used unless there has been a previous IF statement.

Any Blocks of Type works similarly to All Blocks of Type, but only allows checking conditions. You cannot set a value for Any Blocks of Type. It can be used with IF logic to check if any doors are open, or if any Air Vents are not pressurized, for example.

For example, if you want to get only Batteries that have a name including "Station", you can enter "Station" in the block name field, and choose All Blocks of Type. This will select only the Batteries that have "Station" somewhere in their name. It will get Batteries named "Station Battery 5" and "Battery 3 [Station]" but would not get a battery named "Battery 2", because it does not include the filter text.

For IF logic chunks, enter a value in one or more of the boxes to check that the field is equal to the value you entered. The If button next to the field name will become selected, indicating that the field will be used. If you decide not to use the field, you can delete the contents of the box or click the If button to deselect it. The field will only be applied when the If button for that field is selected. The operator (equals sign) can be clicked to change the type of comparison. For numbers, you can use equal, not equal, greater than, greater than or equal, less than, and less than or equal. For other types, you can only use equal andnot equal.

After a variable has been set, it can be used in IF logic chunks to compare a value against the variable. When clicking on an input box for a field in an IF logic chunk, a list of the variables that have been created will be shown below, and can be selected. Note that the type of the field is important. If a boolean (true/false) variable was created, it will only be shown as an option for boolean fields.

When writing the text you want displayed on an LCD panel, you can use any variables that you created in your script by surrounding them with brackets. For example, if you saved a variable called totalpower, you could display its value on an LCD panel by writing [totalpower]. This can be combined with any other text, or any other variables. Total Power: [totalpower] would display Total Power: 3.00MW. See additional information about using LCD panels below.

Using a DO logic chunk allows you transfer items to or from another inventory. To change between Send [x] to [inv] and Take [x] from [inv], click the word to or from. This will toggle between the two.

When sending or taking items, the amount field accepts decimal numbers (ex. 10.4), numeric user-defined variables (ex. oreAmount), and percentages (ex. 10%). You can even take a percentage of a variable (ex. oreAmount%). A note about using percentages, the percent amount is based on the quantity at the time of transfer. So if you transfer 50% of the Stone in an inventory to another inventory, then transfer 50% again, the second transfer sends 50% of what"s left (25% of the original). If you want to send 50% to one place and 50% to another, you"ll need to first send 50% and then send 100%.

In order to send items to an inventory or take items from an inventory, you must give the other inventory a name. This is done by typing a name into the the Inventory line of the other block. If the other block is not otherwise used, you can create a DOlogic chunk at the top of your script for that block, give the correct inventory a name, and leave all other fields blank for that logic chunk. This will define the inventory without applying any actions or changing any properties (though you can also apply actions or change properties if you want).

Let"s create a script that pulls Iron Ore from a Small Cargo Container and puts it into a Refinery. You need two DO blocks for this script; one for the Small Cargo Container, and one for the Refinery. For this example, we will send the ore to the Refinery. Create a DO block for the Refinery first. In the Refinery"s first inventory, enter a name for the inventory (ex. refinv). Now create a DO block for the Small Cargo Container. In the Small Cargo Container"s inventory, find Iron Ore. You"ll see a buttonSend, an input field, the word to and another input field. The first input is the amount, which you can leave blank to send all. The second input is the inventory you"re sending the items to. When you click that box, the refinv inventory you named earlier will be suggested. Click on the name to choose that inventory. The Iron Ore line should look like this: Send(blank) to refinv. Your script is complete. When it is run, it will attempt to send all Iron Ore from the Small Cargo Container to the Refinery"s first inventory (for ores). Note that this same result could be achieved by reversing these blocks, giving the Small Cargo Container inventory a name, and applying Take (blank) from smallcargoinv in the Refinery"s Iron Ore option in its first inventory.

Don"t worry about highlighting and copying, just click the button to copy your entire script to the clipboard and paste it into the editor in Space Engineers.

As you can see, our variable (here named variableName) is followed by a question mark (?), the text to display when true (trueText), a colon (:), and the text to display when false (falseText). For use on the LCD panel, we must enclose this whole string in brackets. In a more realistic scenario, we might want to display ON when our Reactor is on, and OFF when our Reactor is off. We can create a boolean variable called reactorOn for the Reactor"s On/Off state by typing a new variable name (reactorOn) into the Save As box for the OnOff property of the Reactor. For this property, true means the reactor is on. To get the text to display correctly, we can type the following into an LCD panel.

As of Update 1.0.3, it"s also possible to do calculations right inside the text of the LCD panel. This allows you to display your power percentage. Mathematically, power percentage is:

This can cause your script not to compile if you don"t use the correct C# syntax. There is no error checking in VSB to ensure the code you typed is valid.

The Block Name box is where you enter the name of the Space Engineers block you want to work with. If this is left blank, the default value will be used for the chosen block type. Leave this blank.

That"s it! You"re now ready to try the script out. Click the Copy Script To Clipboard button, and paste the code into a Programmable Block in Space Engineers. Running the code will toggle on/off an Interior Light with the name "Interior Light".

In Space Engineers, create a Programmable Block. Go into the Programmable Block"s menu and click Edit. Delete everything in the editor and paste in your script. CTRL-C and CTRL-V work in the editor. Click Check Code to check the code for errors, then click Remember & Exit to save. Be careful, as using ALT-TAB to switch out of Space Engineers will revert your script to the last saved script. It is easy to lose your changes.

To run the script, open the Programmable Block"s menu and click Run. You can also assign this action to your toolbar in a ship, or to a button panel by dragging the Programmable Block to the bar and choosing Run with default argument.

If you want your script to be run constantly (for example, waiting for a door to open and triggering the lights to turn on) you can use the Frequency dropdown in the Script Settings menu. It will automatically run your script every 1, 10, or 100 ticks. There are 60 ticks per second in-game. This feature was introduced in version 1.0.8, but can cause issues when trying to use Arguments in the Programmable Block. With older versions, or to avoid issues with Arguments, you have to use a timer block. Create a Timer block and set the Trigger Delay to 1 second. Click Setup Actions, and drag your Programmable Block to the first space on the bar. Again, use Run with default argument. Then drag your Timer block to the next space on the bar and choose Start. Now start the Timer block, and your script will be executed every second.

A touchscreen or touch screen is the assembly of both an input ("touch panel") and output ("display") device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.zooming to increase the text size.

The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field, heavy industry, automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display"s content.

Historically, the touchscreen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Display manufacturers and chip manufacturers have acknowledged the trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products.

The first finger driven touch screen was developed by Eric Johnson, of the Royal Radar Establishment located in Malvern, England, who described his work on capacitive touchscreens in a short article published in 1965Frank Beck and Bent Stumpe, engineers from CERN (European Organization for Nuclear Research), developed a transparent touchscreen in the early 1970s,In the mid-1960s, another precursor of touchscreens, an ultrasonic-curtain-based pointing device in front of a terminal display, had been developed by a team around Rainer Mallebrein[de] at Telefunken Konstanz for an air traffic control system.Einrichtung" ("touch input facility") for the SIG 50 terminal utilizing a conductively coated glass screen in front of the display.

In 1972, a group at the University of Illinois filed for a patent on an optical touchscreenMagnavox Plato IV Student Terminal and thousands were built for this purpose. These touchscreens had a crossed array of 16×16 infrared position sensors, each composed of an LED on one edge of the screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. A similar touchscreen was used on the HP-150 starting in 1983. The HP 150 was one of the world"s earliest commercial touchscreen computers.infrared transmitters and receivers around the bezel of a 9-inch Sony cathode ray tube (CRT).

In the early 1980s, General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile"s non-essential functions (i.e. other than throttle, transmission, braking, and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input.stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle"s cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC"s touchscreen which would render climate control or stereo operation impossible.

Multi-touch technology began in 1982, when the University of Toronto"s Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass. In 1985, the University of Toronto group, including Bill Buxton, developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems (see History of multi-touch).

In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen.

Sears et al. (1990)human–computer interaction of the time, describing gestures such as rotating knobs, adjusting sliders, and swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger.

Touchscreens would not be popularly used for video games until the release of the Nintendo DS in 2004.Apple Watch being released with a force-sensitive display in April 2015.

A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point.voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.

Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event. Surface acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.

A capacitive touchscreen panel consists of an insulator, such as glass, coated with a transparent conductor, such as indium tin oxide (ITO).electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Touchscreens that use silver instead of ITO exist, as ITO causes several environmental problems due to the use of indium.complementary metal-oxide-semiconductor (CMOS) application-specific integrated circuit (ASIC) chip, which in turn usually sends the signals to a CMOS digital signal processor (DSP) for processing.

Unlike a resistive touchscreen, some capacitive touchscreens cannot be used to detect a finger through electrically insulating material, such as gloves. This disadvantage especially affects usability in consumer electronics, such as touch tablet PCs and capacitive smartphones in cold weather when people may be wearing gloves. It can be overcome with a special capacitive stylus, or a special-application glove with an embroidered patch of conductive thread allowing electrical contact with the user"s fingertip.

A simple parallel-plate capacitor has two conductors separated by a dielectric layer. Most of the energy in this system is concentrated directly between the plates. Some of the energy spills over into the area outside the plates, and the electric field lines associated with this effect are called fringing fields. Part of the challenge of making a practical capacitive sensor is to design a set of printed circuit traces which direct fringing fields into an active sensing area accessible to a user. A parallel-plate capacitor is not a good choice for such a sensor pattern. Placing a finger near fringing electric fields adds conductive surface area to the capacitive system. The additional charge storage capacity added by the finger is known as finger capacitance, or CF. The capacitance of the sensor without a finger present is known as parasitic capacitance, or CP.

In this basic technology, only one side of the insulator is coated with a conductive layer. A small voltage is applied to the layer, resulting in a uniform electrostatic field. When a conductor, such as a human finger, touches the uncoated surface, a capacitor is dynamically formed. The sensor"s controller can determine the location of the touch indirectly from the change in the capacitance as measured from the four corners of the panel. As it has no moving parts, it is moderately durable but has limited resolution, is prone to false signals from parasitic capacitive coupling, and needs calibration during manufacture. It is therefore most often used in simple applications such as industrial controls and kiosks.

In some designs, voltage applied to this grid creates a uniform electrostatic field, which can be measured. When a conductive object, such as a finger, comes into contact with a PCT panel, it distorts the local electrostatic field at that point. This is measurable as a change in capacitance. If a finger bridges the gap between two of the "tracks", the charge field is further interrupted and detected by the controller. The capacitance can be changed and measured at every individual point on the grid. This system is able to accurately track touches.

Unlike traditional capacitive touch technology, it is possible for a PCT system to sense a passive stylus or gloved finger. However, moisture on the surface of the panel, high humidity, or collected dust can interfere with performance.

These environmental factors, however, are not a problem with "fine wire" based touchscreens due to the fact that wire based touchscreens have a much lower "parasitic" capacitance, and there is greater distance between neighbouring conductors.

Self-capacitive touch screen layers are used on mobile phones such as the Sony Xperia Sola,Samsung Galaxy S4, Galaxy Note 3, Galaxy S5, and Galaxy Alpha.

Self capacitance is far more sensitive than mutual capacitance and is mainly used for single touch, simple gesturing and proximity sensing where the finger does not even have to touch the glass surface.

Capacitive touchscreens do not necessarily need to be operated by a finger, but until recently the special styli required could be quite expensive to purchase. The cost of this technology has fallen greatly in recent years and capacitive styli are now widely available for a nominal charge, and often given away free with mobile accessories. These consist of an electrically conductive shaft with a soft conductive rubber tip, thereby resistively connecting the fingers to the tip of the stylus.

An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any opaque object including a finger, gloved finger, stylus or pen. It is generally used in outdoor applications and POS systems that cannot rely on a conductor (such as a bare finger) to activate the touchscreen. Unlike capacitive touchscreens, infrared touchscreens do not require any patterning on the glass which increases durability and optical clarity of the overall system. Infrared touchscreens are sensitive to dirt and dust that can interfere with the infrared beams, and suffer from parallax in curved surfaces and accidental press when the user hovers a finger over the screen while searching for the item to be selected.

A translucent acrylic sheet is used as a rear-projection screen to display information. The edges of the acrylic sheet are illuminated by infrared LEDs, and infrared cameras are focused on the back of the sheet. Objects placed on the sheet are detectable by the cameras. When the sheet is touched by the user, frustrated total internal reflection results in leakage of infrared light which peaks at the points of maximum pressure, indicating the user"s touch location. Microsoft"s PixelSense tablets use this technology.

Introduced in 2002 by 3M, this system detects a touch by using sensors to measure the piezoelectricity in the glass. Complex algorithms interpret this information and provide the actual location of the touch.

The key to this technology is that a touch at any one position on the surface generates a sound wave in the substrate which then produces a unique combined signal as measured by three or more tiny transducers attached to the edges of the touchscreen. The digitized signal is compared to a list corresponding to every position on the surface, determining the touch location. A moving touch is tracked by rapid repetition of this process. Extraneous and ambient sounds are ignored since they do not match any stored sound profile. The technology differs from other sound-based technologies by using a simple look-up method rather than expensive signal-processing hardware. As with the dispersive signal technology system, a motionless finger cannot be detected after the initial touch. However, for the same reason, the touch recognition is not disrupted by any resting objects. The technology was created by SoundTouch Ltd in the early 2000s, as described by the patent family EP1852772, and introduced to the market by Tyco International"s Elo division in 2006 as Acoustic Pulse Recognition.

A real practical integration between television-images and the functions of a normal modern PC could be an innovation in the near future: for example "all-live-information" on the internet about a film or the actors on video, a list of other music during a normal video clip of a song or news about a person.

Unsupported touchscreens are still fairly common in applications such as ATMs and data kiosks, but are not an issue as the typical user only engages for brief and widely spaced periods.

Touchscreens can suffer from the problem of fingerprints on the display. This can be mitigated by the use of materials with optical coatings designed to reduce the visible effects of fingerprint oils. Most modern smartphones have oleophobic coatings, which lessen the amount of oil residue. Another option is to install a matte-finish anti-glare screen protector, which creates a slightly roughened surface that does not easily retain smudges.

Touchscreens do not work most of the time when the user wears gloves. The thickness of the glove and the material they are made of play a significant role on that and the ability of a touchscreen to pick up a touch.

Embedded data is any extra information you would like recorded in your survey data in addition to the question responses. It can be used to store information such as:

The value for your embedded data field can be pulled from data that you have uploaded into a contact list, information appended to the respondent’s survey link, built-in fields provided by Qualtrics, or values set in the survey flow.

Warning: All embedded data field names were previously case-sensitive. For a vast majority of users, embedded data field names are no longercase-sensitive, meaning “test” and “Test” would be treated as the same field. However, we still advise matching cases as a best practice, since there is a small portion of accounts where this change has not been made.

Warning: Embedded data may be visible to individual survey respondents and should not contain sensitive data that a respondent is not intended to view.

Attention: If you are creating your own special embedded data variables, here are some default fields that you should never name an embedded data field (not case-sensitive):

If you name an embedded data field one of these names, you will see the message, “The value for Embedded Data field X is left blank intentionally to prevent issues with survey metadata”, and no data will be recorded for that field. In addition, here is a list of existing embedded data you can use, but cannot set custom values for.

Number: This is a continuous variable type. Values must be in numeric format, and reports can determine both statistical values and counts of individual answers given. For example, you can use a Number embedded data to calculate average age, but also to create a table showing how many 18 year olds were in your study. This type is not compatible with breakouts.

Filter Only: This type of variable is similar to a Text Set type, but allows you to filter your data by text contained within the values, not just exact values and emptiness. For example, you can filter by all departments containing “Sales” in the name, not just Sales.

Qtip: If your data is not displaying, make sure it is compatible with the Embedded Data variable type. For example, text data will not display for a field set to the Number variable type.

A contact list is a mailing list used for distributing surveys many ways on Qualtrics, including email, personal links, and SMS distributions (text messages). In addition to including names and email addresses for each recipient on this list, you can include any demographic or unique data you’d like in a contact list. For example, in addition to name and email, the contact list in the screenshot below includes the embedded data fields Position, State, and Project Number. All we had to do to include this information in the contact list was add those columns of data to our contact file before we imported it.

However, just because the embedded data is in our contact list doesn’t mean it’s automatically included in the survey data. By adding an embedded data element in your survey flow, you can have this information saved in your results for use in your analysis.

Qtip: Although you need an embedded data survey flow element to add embedded data to your recorded results, you do not need this element to use embedded data in piped text, branches, or display logic.

Qtip:Forgot to follow these steps before launching your study? No worries! If there was embedded data in the contact list that you distributed the survey to, you can retroactively add fields to the survey flow after the survey is finished. Note that only embedded data that existed in the contact list at the time of response creation can be retroactively added to the survey flow. Embedded data added to the contact list after response collection cannot be added retroactively to the survey flow and pulled into your data set.

If you’re not distributing your survey to a contact list, you can still bring embedded data into the survey for each respondent by adding your embedded data field names and values to the end of the survey link.

Embedded data can be added to any kind of survey link, and you can add many different embedded data to one link. To learn more with step-by-step instructions, see the Passing Information via Query Strings support page.

In addition to creating your own embedded data variables or pulling them in from other sources, you also have access to some built-in variables that Qualtrics records for every response. These elements can be added to the survey flow before or after you have collected responses by using the steps described in the Creating an Embedded Data Element section. You won’t need to set a value when you use these fields, because each one performs a special function in the responses (described below) and uses this to determine the value. Note that because of this, you will be unable to set custom values for these fields in the survey flow.

This element provides you with the contact ID associated with the respondent who took your survey. Note that this field will be empty if you distribute via an anonymous distribution method.

When using the offline app, this element will record which device was used to record the response. This field must be set in your Offline App and can be updated at any time by clicking the cog in the top-right corner of the app, but it will only affect the DeviceIdentifier for future responses. For more information, visit the Setting Up the Offline App support page.

This element will give you the ID of the contact list (a.k.a. panel) to which each respondent belongs. Matching Panel IDs can be found in the Qualtrics IDs section of Account Settings.

This element allows you to track which language a respondent takes the survey in. This information is reported in the survey data using a two letter language code as discussed in the Available Language Codes section of the Translate Survey page.

This can be used as a URL parameter to pre-populate survey responses. For example, if you wanted to have a survey question asked within an email, the image associated with each answer choice would pass a different value and when the respondent lands on the full survey, the value would already be answered, ready for the respondent to change or submit that response and continue with the rest of the survey. For more information, see How to Use Q_PopulateResponse.

This element allows you to see the total duration (in seconds) of the survey response. This includes time with the survey open, and time spent away from the survey if the user closes out of the survey and returns. This was implemented on July 16, 2012, and is not available for responses recorded before that date.

This element allows you to view the URL first used to access the survey. Note that it omits the base URL, showing only the path and extra URL data. This is a useful tool for diagnosing issues where URL parameters are not recorded as expected.

When you use zip code content validation on a question with a text entry field, you can use Q(State/City)_ExportTag_suffix as embedded data to record the city or state indicated by a zipcode. For example, if your second question asks for the zip code, and you want the state, you’d call the embedded data QState_Q2. If Q2 is a form asking for name, phone number, and lastly zip code, it would be QState_Q2_3, since zip code is the third text field. For more information, see the step-by-step on the Validation support page.

This element shows the page the respondent was on when they clicked the survey link. For most emailed surveys, you will see a URL for the email provider. If the survey is linked to with an automatic redirect, such as a URL redirect at the end of another survey, no value is recorded.

This element will give you the response ID that Qualtrics assigned for that response. This ID can be used in Web Services, API calls, and other applications. This field is not available for imported responses. However, imported responses are still assigned a responseID when imported, and this ID is available in the respondent information section of your dataset.

This element provides information about the respondent’s operating system and browser. For an easier-to-read version of this, consider adding a hidden meta info question to your survey.

A web service allows you to pull data from an external website into your survey. For example, you might want to pull in today’s top headline from CNN or customer details from your own internal database. Information drawn from a web service is saved as embedded data. For an in-depth look at using a web service to draw embedded data from another website, refer to our Web Service page.

Qtip: XM Directory is not the same as CoreXM Contacts. If you do not have access to a brand-wide directory of contacts, you do not need to read the support page on managing and refreshing embedded data.

Qtip:You may not be able to select this field from the list of existing fields. Make sure you type the name of the field exactly the same way it appears in your directory, including the same spelling, spacing, punctuation, and capitalization.

Warning: If you delete an embedded data field after you have collected data, all the embedded data’s values will be permanently deleted from all responses. The only exception is if the embedded data was originally stored in a contact list or query string – then you can add the embedded data field back to the survey flow to retrieve the data. However, you cannot do this with values originally set in the survey flow. Please do not delete embedded data from the survey flow unless you are absolutely sure you want to lose this data, or have not collected any data yet.

If you plan on using query strings, either remove spaces in the names and values of the embedded data you use, or use underscores to prevent yourself from needing to encode spaces in the URL. For example, StoreID and Store_ID can be easier to use with a query string than Store ID.

If your list of embedded data gets long or involves a complex naming system, keep a document somewhere with a list of all your embedded data and what they’re for. That way you can always double-check for spelling, capitalization, and spaces, in addition to the purpose of the field. These documents can also help you, any colleagues you are working with, and any customer support representative you work with troubleshoot when you have questions.

If you are using built-in embedded data fields, you can save the fields in a survey flow embedded data element, as shown below. However, you cannot set values for these fields, because the way respondents complete the survey will determine those fields’ values.

Example: For example, in this survey flow, even if a respondent has a Snack embedded data field that is initially set to Good, the value will be overwritten as Bad because the second embedded data is not nested under the branch logic correctly.
