touch screen monitors instructions use for test manufacturer

Touch screens are devices that recognize the presence of contacts and generate responses. The presence can be delivered via touch gestures or stylus. The response can be various such as haptic, visual, audio, etc. Hence, touch screens are input/output devices.

Touch screens usually consist of three main components, which are touch sensors, touch controllers, and drivers. Touch sensors can use different technologies, such as capacitive, resistive, optical, etc. Controllers are the bridge between the sensor and the computer, and they can have different digital interfaces such as SPI,I²C, etc., for the connections. Drivers translate touch events into a response.

Touch screens make the use of most devices much more manageable and user-friendly. They are widely used in all smart devices, such as in mobile phones, ATMs, point of sale (POS) devices, in the automotive industry as part of the in-vehicle infotainment systems, human-machine interfaces (HMI) in industrial products, etc. Since most of the touch screen components become cheaper over the years, touch screen enabled devices are increasing. With the development in material science, curved and flexible touch screens that provide haptic feedback have become the new touch screens trend. With the developments in network technologies, Internet of things (IoT) enabled systems are also being equipped with more touch screens.

Touch screens interacted with touch gestures. The benefits and the design-wise advantages of touch gestures make them one of the most popular system-human interaction methods.

Touch gestures generate a stream of touch events such as touch down, touch moving, touch up, etc., at the touch controller. These touch events are then collected via a hardware buses.The event stream is then used to determine the type of gesture and, eventually, as input in updating the user interface (UI) content. As an example, a swipe gesture would scroll a list on the UI.

The end-user expects reliable touch gesture responses. Touch gestures" functionality and performance are subject to the product"s electrical design, selected touch panel technology, and touch controller features and configuration. The operating system, GUI framework, and applications come into the picture in a final end-user product. A touch controller reads the touch panel signal and reports the detected touch events to the central processor, which executes the operating system (OS), GUI framework, and end-user applications.

Smooth user experience relies on accurate and repeatable touch gestures, which are only possible when the touch user interface (UI) is functional, responsive, and fast over the entire surface area. The manufacturers of touch screen devices need to perform various tests on the system, device, and individual component level to fulfill the end user"s expectations.

These tests measure the DUT"s (device under test) tap accuracy and repeatability performances. The results are reported with maximum accuracy and repeatability errors, and missing input values. The results are used to determine the hardware"s ability to write consistent coordinates, especially when the touch panel"s same location is pressed repeatedly.

These tests measure the DUT"s performance when a single point is pressed and hold. It reports the maximum measured stationary Jitter calculated from the first coordinate reported by the DUT.

These tests measure and report the DUT"s stationary and non-stationary reporting rates. Here how a stationary reporting rate for an individual tap looks like:

Various other tests can be considered as performance tests on the panel level. Such tests are for analyzing the First Contact Latency and Hover, for example. As part of the first contact latency test, the maximum allowed response latency from active and idle states are measured.

As part of the hover test, Jitter, missing swipes, and the maximum permitted hover distance from the DUT"s surface are measured. There arealso othertests performed just with multi-finger setups. One of them is the separation test thatmeasures the DUTs ability to separate distinct fingers based on their distance from each other. The test reports maximum allowed finger separation distances in vertical and diagonal alignments.

Performance tests are accomplished with robot-assisted platforms that mimic human interaction with touch screen systems. These platforms run on 3-axis gantry stages that use linear guides and encoders for precise positioning, and high accuracy. The Z-axis is equipped with different actuators, even for stylus testing. Actuators carry fingertips that accomplish the touch activity to perform the gestures and other tests. The Z-axis may have more than one finger, and in that case, the system includes an azimuth unit.

Touch screens are everywhere, and for good reason. This technology has made transactions, purchases, and inquiries faster and easier for everyone. But in these touchless times, is there still a place for touch screen technology in our everyday lives?

From avionics and heavy machinery to tablets and advanced automotive applications, touch screen technology has become an integral part of our everyday lives. They are found in fast-food restaurants and supermarkets, commercial centers and office buildings.

However, the COVID-19 pandemic has raised concerns about using touch screens. In this article, we touch on the benefits of this technology—and what both consumers and businesses can do to make using touch screen devices safer for everyone.

This is perhaps the greatest appeal of touch screens: using them comes intuitively to everyone. You don’t need to have a computer background to reach out and tap icons to get information, make a purchase, and other transactions. Because they are more visual than other devices, touch screens minimize errors. The fact that touch screen devices are so easy to operate is the reason it has become widely used in society today.

As a customer, you get what you need to know or do in a faster, easier way. For businesses, it accelerates employee training and improves the efficiency of your operations.

Because touch screens do not require a mouse or keyboard, they can accommodate users who may have hand disorders such as arthritis and carpal tunnel syndrome. Touch screens can also help those who have speech difficulties avail of products and services that they need and enjoy.

From paying bills and buying movie tickets to purchasing a meal and withdrawing from an ATM, touch screens accelerate service in establishments around the world. They reduce queues and eliminate face-to-face contact.

While touch screens can help with physical distancing, your hand still comes in contact with the screen. We all know that hand hygiene is crucial to curbing the spread of COVID-19. Does this mean we’re supposed to stop using touch screens?

“Touchscreens are now in many places in UK society, so it’s often hard to avoid needing to use them,” Michael Head, a senior research fellow in global health at the University of Southampton, told

The same can be said for the rest of the world. Given how ubiquitous touch screens are in everyday life, that’s not feasible. What, then, should consumers do? The same thing that you do whenever you leave your home and touch any surface: avoid touching your face and wash your hands thoroughly as soon as you can.

Business establishments with touch screens should do their part. Following the manufacturer’s instructions on cleaning methods and materials, they should clean and disinfect touch screens after each use, either by a customer or an employee.

In truth, regular cleaning of touch screens should be done whether there is a pandemic or not. Keeping touch screens free from bacteria and viruses will allow you and your customers to continue enjoying the ease and convenience that this technology brings to everyone.

A slim stripe of double-sided foam-tape should be used to fix the touch sensor on the metal frame of the TFT panel. The touchscreen sensor needs to be mounted with a constant distance between sensor and LCD display. The distance should not vary under compression, different contact pressures or temperature fluctuations.

The hole edge of the touchscreen should be fixed and the tape 1-2mm thick. Don´t leave any room for gaps. The tape prevents the space between touch-sensor and TFT panel from dust and dirt. The tape fixes the sensor within its place.

Please be aware that some sealing materials contain chemicals (sulphur, acidic materials or chlorine) which can influence the functionality of your touchscreen. Before selecting sealing materials, it`s important to know the ingredients and chemical compounds. It´s important to keep touchscreens away from chemically acting and acidic materials.

The precise positioning of the touch sensor is extreme important. A bit of exercise is needed to place the sensor on the vertical and horizontal axis of the TFT display panel. The touchscreen-sensor needs to be exactly aligned with the LCD panel. Place the display with the front to the top on a foam mat and be careful with the components on the back of the panel.

Pay attention with the correct positioning of the flex tail cable. If you are not sure which position is the right one please contact us or look at the technical instructions/drawings of your sensor. The tail is only bendable in one direction and at one point.

The last step is the precise positioning of the touchscreen on the LCD panel. Make sure the sensor is straight and central on the visual surface of the TFT LCD display.

Touchscreen Mounting As soon as you are satisfied with centration and positioning of the touch-sensor, you are ready to permanently install the senor to the LCD panel.

If you want to remove the touch sensor don`t try to pull it up from the TFT LCD display panel! The glass could break and injure you and others! Use a fishing line, steel wire or a razor blade to cut the tape carefully. Start at the top of the panel and then move upwards at the sides. Be careful! Don´t scratch the TFT panel or even the touch sensor. Hold the touchscreen when the display comes off.

Use isopropyl alcohol to remove residues of the tape from the back of the touchscreen-sensor. If you use solvents follow the instructions of the manufacturer. Follow as well the instructions of the manufacturer according to the usage of chemicals for the LCD display panel.

Yes, Hope Industrial touch screens use resistive technology, which is pressure-sensitive and can be used with any type of stylus, as long as it is not sharp or rough (which could damage the touch screen surface). Please contact our sales department for more information.

After initial setup, the touch screen should not require periodic re-calibration. Installing new drivers could erase a previous calibration and at time re-calibration is done by preference since some users prefer a different calibration style (e.g.: pointer centered on the finger-tip vs. centered on the finger).

Drivers are available for a wide variety of current and legacy operating systems, including all major Windows versions, Microsoft Embedded operating systems, Apple Mac, and many others. A full list and downloadable drivers are available in our support section.

Yes. Our touch screen drivers allow multiple displays to be connected to a single PC whether in mirroring mode (multiple screens showing the same desktop) or extended desktop (a single desktop stretched across multiple displays).

Our Windows drivers allow each touch screen to be calibrated independently whether you are using USB or Serial for connection to the PC. Once configured, the cursor will follow your finger to any connected touch screen. For configuration help or more information, please contact our support group for assistance.

Support for Linux-based operating systems is available through both native drivers, and by using driver-less methods that rely on the HID device compatibility of our touch screens. A full review of the available methods is available on our blog.

This enhanced version of the Animal Behavior Environment Test (ABET) system retains all the features of ABET II Standard while adding convenient tools for the display of screen images and the monitoring of touch screen responses.

There are several interface systems and behavioral control software packages on the market, however, only ABET II offers a system that can be user customized and programmed with no programming experience. Every effort has been made to make this easy enough to use for those with minimal operant conditioning experience, yet powerful enough to run complex schedules for the experimental analysis of behavior. If you can conceptualize your experiment in a spreadsheet or flow chart, you can create the conditions needed for a complete ABET II Operant Schedule. This is the only product that makes it just as easy to present a screen image as it is to turn on a stimulus light and just as easy to record a touch response to that image location as it is to record a lever press. This one ABET II application includes five major components on easy to select folder tabs.

Run multiple conditions in the same group and all conditions will always be evaluated. This is significantly different from other systems that may either exit a state as soon as it tests true or never exit to a new condition without complicated links

Never write a single line of program code. ABET II will print all schedule details in a well organized spreadsheet like format that is color-coded to make it easy for anyone to follow each logical step. Schedules can be "versioned" and locked to prevent any data corruption once an experiment is started

Expand session variables as need without limit using single line or multi-line fields for notes, animal identification, weight, dose or treatment, and other information

Perform unlimited user defined analysis of measures / paths (latencies), bouts, or counts with Analysis Set Designer. Because ABET II records every detail of a session with millisecond precision data elements need not be pre-programmed as with other systems

Install ABET II on your laptop, office computer or any computer not connected to hardware. The Virtual Interface is a duplicate of the environment that you have in your lab. You can now create, review, and test schedules and you can review or analyze lab data in a more convenient setting. Pass schedules and data to and from your lab either by a network connection or any removable media. ABET II also includes convenient backup and restore utilities.
