You interact with a touch screen monitor constantly throughout your daily life. You will see them in cell phones, ATM’s, kiosks, ticket vending machines, manufacturing plants and more. All of these use touch panels to enable the user to interact with a computer or device without the use of a keyboard or mouse. But did you know there are several uniquely different types of Touch Screens? The five most common types of touch screen are: 5-Wire Resistive, Surface Capacitive touch, Projected Capacitive (P-Cap), SAW (Surface Acoustic Wave), and IR (Infrared).
We are often asked “How does a touch screen monitor work?” A touch screen basically replaces the functionality of a keyboard and mouse. Below is a basic description of 5 types of touch screen monitor technology. The advantages and disadvantages of type of touch screen will help you decide which type touchscreen is most appropriate for your needs:
5-Wire Resistive Touch is the most widely touch technology in use today. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. When a user touches the screen, the two metallic layers make contact, resulting in electrical flow. The point of contact is detected by this change in voltage.
Surface Capacitive touch screen is the second most popular type of touch screens on the market. In a surface capacitive touch screen monitor, a transparent electrode layer is placed on top of a glass panel. This is then covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body. Some of the electrical charge transfers from the screen to the user. This decrease in capacitance is detected by sensors located at the four corners of the screen, allowing the controller to determine the touch point. Surface capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge.
Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi-touch activation (simultaneous input from two or more fingers). A projected capacitive touch screen is composed of a sheet of glass with embedded transparent electrode films and an IC chip. This creates a three dimensional electrostatic field. When a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points. All our P-Cap touch screens feature a Zero-Bezel enclosure.
SAW (Surface Acoustic Wave) touch screen monitors utilize a series of piezoelectric transducers and receivers. These are positioned along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. When the panel is touched, a portion of the wave is absorbed. This allows the receiving transducer to locate the touch point and send this data to the computer. SAW monitors can be activated by a finger, gloved hand, or soft-tip stylus. SAW monitors offer easy use and high visibility.
IR (Infrared) type touch screen monitors do not overlay the display with an additional screen or screen sandwich. Instead, infrared monitors use IR emitters and receivers to create an invisible grid of light beams across the screen. This ensures the best possible image quality. When an object interrupts the invisible infrared light beam, the sensors are able to locate the touch point. The X and Y coordinates are then sent to the controller.
We hope you found these touch screen basics useful. TRU-Vu provides industrial touch screen monitors in a wide range of sizes and configurations. This includes UL60601-1 Medical touch screens, Sunlight Readable touch screens,Open Frame touch screens, Waterproof touch screens and many custom touch screen designs.

LCD touch panel, also known as touch panel, is an inductive LCD device that can receive touch and other input signals. When touching the graphic buttons on the screen, the tactile feedback system on the screen can drive various connection devices according to the pre-programmed program, which can replace the mechanical button panel and create a vivid audio and video effect through the LCD screen.
The working part of the LCD touch screen is generally composed of three parts: two transparent resistive conductor layers, an isolation layer between the two conductor layers, and electrodes.
For operational convenience, people use a touch screen instead of a mouse or keyboard. When working, we must first touch the touch screen installed in the front of the display with a finger or other object, and then the system is positioned according to the location of the finger touch icon or menu to select the information input.
LCD touch screen consists of touch detection components and touch screen controller; touch detection components installed in front of the monitor screen, used to detect the user’s touch location, accepted and sent to the touch screen controller.
The main role of the LCD touch screen controller is to receive touch information from the touch point detection device, and convert it into contact coordinates, and then sent to the CPU, it can also receive commands from the CPU and to execute.
The majority of software has been traditionally designed for people who use a standard keyboard, mouse and screen display. A student needs good hand control, vision, hand-eye co-ordination, hearing (some programs provide text-to-speech and other auditory feedback) as well as cognitive abilities in order to access most standard and even some special needs software.
This can be a critical barrier to learning for many students with special educational needs. Some will need some form of special access to allow them to use some computer software. Some will require adapted mice, trackballs, head pointing systems or mini or enlarged keyboards. There is a range of external keyboards, modified and programmable external keyboards. In this article, the use of onscreen, sticky or virtual keyboards will be discussed.
A student may require a keyguard consisting of a metal or plastic plate with punched holes, fitted over the keyboard as it reduces accidental key-presses caused by hand tremor. Some users can rest their hands on the keyguard surface to more accurately locate the keys. Microsoft has some access software built into the computer’s operating system including TTS and an onscreen keyboard. MAC OS and MS Windows computers have programs that allow users to control the mouse pointer with the keys on the numeric keypad at the right hand side of the keyboard.
If a user has severe physical disabilities which means that keyboard use is either impossible, very tiring, or very slow, then voice recognition, or an ‘on-screen keyboard’ program which enables the user to select letters and commands using a single switch from a ‘keyboard’ displayed on screen, may be potential alternatives.
A virtual keyboard is a software and/or hardware component that allows a user to enter characters. A virtual keyboard can usually be operated with multiple input devices, which may include an actual keyboard, a computer mouse, a head mouse, and an eye-mouse. On a desktop PC, one purpose of a virtual keyboard is to provide an alternative mechanism for disabled users that cannot use a physical keyboard. Another major use for an on-screen keyboard is for bi- or multi-lingual users, who continually need to switch between different character sets and/or alphabets.
Although hardware keyboards are available with dual layouts (for example Cyrillic/Latin letters in various national layouts), the on-screen keyboard provides a handy substitute while working at different stations or on laptops, which seldom come with dual layouts. The standard on-screen keyboard utility on most Windows systems allows hot-key switching between layouts from the physical keyboard (typically alt-shift but this is user configurable), simultaneously changing both the hardware and the software keyboard layout. In addition, a symbol in the sys-tray alerts the user to the currently active layout. [Source: http://en.wikipedia.org/wiki/Virtual_keyboard ]
Some of the features of onscreen keyboards, in isolation or used in tandem, may assist in some students being more independent users of their computers.
Touch-screens eliminate the need for keyboards, but what happens when students require need to access the programs running on the school’s touch-screen system, either to change something or fix a problem? If they have custom made programs, the programmer may have difficulty accessing those programs without a physical keyboard, wasting valuable time. Schools can’t afford the frustration when their students need to use their touch screen system.
SofType can be accessed using a mouse or mouse emulator such as the HeadMouse Extreme. SofType is compatible with Windows 2000 and XP as it works by generating an image of a keyboard on the computer screen. When a key is selected, the character represented by that key is sent to the active Windows application.
KeyStrokes is a full function advanced virtual on-screen keyboard that allows you to type with a mouse, trackball, head pointer or other mouse emulator to type characters into any standard MAC OS application.
These commercial keyboard layouts are available for customising to meet very specific needs. They offer a large range or pre-designed virtual keyboards and they can be downloaded and trialled for up to 30 days.
OnScreen has WordComplete, which is not the same as word prediction. WordComplete just attempts to complete the word you are working on, whereas word prediction attempts to ‘read ahead’
TouchStrokes is ideal if students work with a touch screen, electronic white board, or set-up a touch screen kiosk. It is also suitable for art and design students or for artists working with large graphic tablets or server managers that want to eliminate the clutter of having multiple physical keyboards on a desk as this provides a workable and space saving solution. People with disabilities can use the KeyStrokes virtual keyboard, which offers special accessibility features.
TouchStrokes works with any mouse or mouse emulating device that is compatible with Mac OS X. This includes the Wacom Graphire and Intuos tablets and Cintiq displays. It also includes Mac OS X compatible touch screens such as those from TrollTouch or just about any touch screen using the drivers from Touch-Base.
OnScreen provides On-Screen keyboard emulation that works with any MS Windows program. The Assistive Technology Version provides a wealth of features specifically designed for use by individuals who can not easily use common input devices. OnScreen provides a powerful interface through any pointing device by providing on-screen keyboards, Word Prediction / Word Completion, user programmable macros, and complete control over all computer functions.
OnScreen uses a concept found in fighter planes, helicopters, tanks, and automobiles. That concept is called “Heads Up Display” technology and its principal objective is to keep the user’s focus and concentration centred in one place. OnScreen uses that concept to reduce the visual re-focusing and re-positioning, caused by the heads up and down motion of going from screen to keyboard to screen, and the resulting confusion it causes.
OnScreen is used by individuals who need an alternative to the physical keyboard, can use a pointing device or switch, and need an on-screen keyboard as their primary text input device
WiViK can help individuals of all ages who are unable to use a physical keyboard, such as those with spinal cord injuries, amyotrophic lateral sclerosis (ALS), muscular dystrophy, and cerebral palsy. Any pointing device or one through six discrete switches may be used as input. There are many alternative pointing devices and switches available in the assistive technology field that work with WiViK. All on-screen (virtual keyboard) keys work just as they would if students were typing on a standard computer keyboard. Students just select a key and WiViK sends it to their word processor, e-mail message, web page or other text-based application that students may be using. Keyboards can contain any keys students want, can be moved anywhere on the screen and can be made any size.
WordQ uses advanced word prediction to suggest appropriate words to make typing with WiViK faster and to help with spelling. As you type, WordQ continuously presents a list of relevant correctly spelled words within the WiViK keyboard. When the desired word is shown, you can choose it with a single keystroke. Speech feedback enables you to more easily choose words and to identify mistakes in all applications. WordQ also acts a text reader to help users proofread and/or read existing or scanned text.
Different virtual, onscreen or sticky keyboards are available from the manufacturers and distributors of the respective IWB companies. Teamboard, Hitachi, Smart Boards and Promethean all provide a functional onscreen keyboard, usually activated from a menu in their software or from a physical button or icon on the board itself.
The functionality and features vary. They are not essentially designed to meet or resolve disability issues. Rather, they provide keyboard access to finger pointing and stylus input for users who are engaging with and accessing the surface area of the IWB.
Click-N-Type is an on-screen virtual keyboard designed for anyone with a disability that prevents him or her from typing on a physical computer keyboard. As long as the physically challenged person can control a mouse, trackball, touch screen or other pointing device, this software keyboard allows users to send keystrokes to virtually any Windows application that can run within a window. The Click-N-Type Virtual Keyboard is a 32 bit application that requires Windows 95/98/ME/NT/2000/XP/Vista or later.
Users can choose the font and font attributes such as Point Size, Bold and Italic. Note: The two rows of alphabetic keys maximises available vertical screen space while minimising mouse movement. However, for those students who are accustomed to and proficient with the QWERTY keyboard, they provide a QWERTY layout designed with the CNTDesigner.
The Word Prediction window uses 8 point “MS Sans Serif” font by default. If users have low vision, they can select the font, size and style, using the “Prediction – Set Prediction Window Font…” menu command. Since a larger font requires a larger window, users can resize this window, and its size will be remembered each time they run the Click-N-Type Virtual Keyboard. This is a unique and very powerful feature as it provides Word Prediction for trial purposes or for full-time use.
On-Screen Keyboard is an accessibility utility that displays a virtual keyboard on the computer screen that allows people with mobility impairments to type data by using a pointing device or joystick. Besides providing a minimum level of functionality for some people with mobility impairments, On-Screen Keyboard can also help people who do not know how to type.
The Inference Group at Cambridge University originally intended to create a method of entering text into PDAs and other mobile devices. The result, however, provided a vital alternative to standard On-Screen Keyboards that are used by thousands of people with physical disabilities. Most OSKs have a layout very similar to a regular keyboard only displayed on the screen rather than as a physical group of keys. Dasher is radically different and as a consequence can provide typing rates of up to 39 words per minute (although 20-30 wpm is more realistic).
This article is a brief discussion into some of the issues and implications of sourcing appropriate onscreen keyboards. There is a great deal of choice. Each potential solution offers technologies that may cater to generic or specific access, vision, communication, sensory and/or cognitive need.
It is a matter of trialling one or more programs and experimenting with the size, location, keyboard layout and other functions of the onscreen keyboard. Each has its own benefits and attributes. Users who are vision impaired will require a keyboard that can bev enlarged and also choose a different sized font, or coloured font and background. Some onscreen keyboards have abbreviation and expansion options, Word Prediction panels and multiple language support. Others will always “stay on top” and push to the front of all other windows. If you require test-to-speech, then a keyboard that has speech or works alongside a TTS program that will voice all keystrokes or completed words may need to be experimented with and trialled.

As another user suggested, the fact that the LCD screen does not respond to movements of the faders on the control surface suggests it"s not a problem with the LCD itself. Also, resistive touchscreens tend to not fail completely at once; rather, they degrade slowly over time.
I suspect that there is a separate module for digitizing analogue controllers - including the faders and the touch screen - that then connects to the x86 motherboard in the OASYS. This module probably connects to the motherboard via a simple USB connection, and if this connection becomes loose, you will have the exact symptoms you"re describing.
This could be an issue with the settings for On-Screen keyboard which you have setup on the computer. It might also be an issue with the system files.
The bad news: We’re all getting laptops that have a touchscreen on the bottom instead of a keyboard. I know. You hate the idea. That’s why it’s the bad news.
The good news is that these touchscreen keyboards won’t look, act or work the way you think they will. In fact, I think you’ll love these devices. That’s why it’s the good news.
At Apple’s Worldwide Developers Conference (WWDC), which it said this week will take place starting June 4 in San Jose, the company could announce an all-screen keyboard for the iPad — a replacement for the iPad Pro Smart Keyboard — and possibly a two-screen laptop.
Another reason for the opposition is that two-screen laptops aren’t new. We’ve seen the idea tried in the past ten years in the form of Canova’s Dual-Screen Laptop, the Acer Iconia 6120 Dual Touchscreen Laptop, the Toshiba libretto W105-L251 7-Inch Dual Touchscreen Laptop and others.
Apple has been filing patents in this category for years. Two more Apple dual-screen laptop patent applications have been published in the past three weeks.
As mere patent applications, they don’t reveal Apple’s actual plans. However, they do serve as an example of how companies want to use advanced technology to make all-screen keyboards far more appealing.
Apple’s most recent two-screen laptop patent shows how flexible displays will enable on-screen keyboards with raised keys that can be physically pressed.
Apple achieves this in part by using a flexible display, with a keyboard-like structure underneath. The on-screen keyboard would actually have key travel. In other words, it would be a hybrid of an on-screen keyboard and a physical keyboard.
The “virtual” keys can be physically pressed, and they can also raise bumps on the screen when the virtual keyboard is on the screens. You’ll be able to feel where the keys are before you press them.
It also describes the use of next-generation haptics that vibrate keys when they’re pressed with the simulated feeling of a physical keyboard. No doubt sound would be added as well to further simulate the experience of using a physical keyboard.
Apple has for three years sold MacBook and MacBook Pro laptops that feature a “Force Touch” trackpad. Apple uses a “Taptic engine” (Apple’s branded haptic part) and electromagnets to simulate physical movement and trackpad clicking.
Steve Jobs detailed the benefits of replacing physical keyboards with virtual ones in his 2007 introduction of the iPhone. The main benefits, of course, are that you get more screen real estate and also more flexible interface options.
Apple’s patents show an iTunes and Apple Music interface that replaces the on-screen keyboard with music controls, such as an equalizer, when one of these applications is running.
It’s easy also to imagine what kind of interfaces third-party developers could build: turntables for DJs, drawing pads for illustrators, advanced calculator keyboards for eggheads, speech notes for business presentations and game-specific game controls for games.
The most recent patent shows how the bottom screen can also display application-specific content or interfaces but instantly turn into a keyboard when you place your hands on it.
I mentioned at the top that I think Apple’s first all-screen keyboard might be an even smarter iPad Pro Smart Keyboard than the company currently sells. Apple’s recent patent specifies an all-screen version for iPad. I also said it might announce a two-screen laptop.
It would make sense for Apple to announce all-screen iPad keyboards and two-screen laptops at a developer event, because the value of this kind of laptop lies in what third-party developers do with them. The main benefit is custom, application-specific interfaces. So when Apple starts working on the manufacturing of such devices, it makes sense that we’ll hear about it in advance at a developer event so applications will be ready when they ship the hardware.
There’s even a security element to this scenario. Locking down a system to reduce the attack surface might actually involve the removal or addition of keyboard interface options.
While dual-screen laptops will enable countless new options, the centrality of keyboards to our work will decline. Over time, we’ll get used to talking to our virtual assistants, and their agency will extend to the typing we do.
While you’re not using the bottom screen keyboard, that screen can be put to use displaying notes or any other content. For a writer, for example, having your prose on top and notes and resources on bottom is a better way to write. And developers can never get enough screen real estate while coding.
In other words, a laptop without a physical keyboard does not mean you can’t use a physical keyboard. It simply means you have more keyboard choice and more screen real estate.
One mechanism for this change is generational. Members of the so-called iGen generation, born between 1995 and 2012, have never known a time before smartphones. People now entering the workforce are iGens. They live on their phones, are more comfortable typing on a smartphone screen than a laptop physical screen, and will easily adapt to using two-screen laptops and on-screen keyboards at work.
After all, any two-bit, third-rate, bargain-basement company can build a mechanical keyboard. But only the top companies such as Apple, Google and a few others will be able to combine patented actuators, patented haptics and advanced A.I. to construct a keyboard. The main companies we buy laptops from have a powerful incentive to move into two-screen laptops.
