touch screen monitors instructions use for test supplier

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.

Healthcare providers of all types – physician’s offices, urgent-care clinics, and large hospital systems – have found that touchscreen technology has many applications in the medical field. From helping a lost patient easily find his way to his doctor’s office in time for their appointment, to having a new mother digitally sign discharge papers for herself and her newborn. Touchscreen devices can streamline processes, save money, and increase patient satisfaction.

For patients to get the care they need, they first have to get to their destination. But hospital systems, medical office buildings, and clinics can be tricky to find their way around.

A study performed at Emory University Hospital once found that wayfinding challenges cost the hospital system over $220,000 per year. The consequences include missed appointments, negative feelings associated with the care provider, and decreases in employee productivity when they have to stop their work to give directions.

Physical accessibility – Screens can be configured so that wheelchair users can easily view their content from a seated position, and some mounts allow for screens to be tilted to meet patient needs further.

Auditory accessibility – Patients with hearing loss might be reluctant to approach an employee for directions. A touchscreen kiosk allows them to the opportunity to obtain directions in a visual format instead.

Visual accessibility – A touchscreen device provides a variety of options for users who have visual disabilities. They can adjust brightness or contrast, increase text size as needed, or even click a button to hear text read aloud.

Linguistic accessibility – Hospital systems often need to provide wayfinding resources in multiple languages based on the population they serve, which can make for crowded, difficult-to-read signage. A touchscreen device allows users to select their language as part of the wayfinding process.

Whether at a doctor’s office, an urgent care clinic, or a major hospital system, touchscreen kiosks are often used as patients sign in. They can enter their personal information, indicate their symptoms, provide their insurance information, and even make payments.

One of the advantages of using touchscreen technology to register patients is that it allows for a simplified check-in process. Patients benefit because the process takes less time overall, and providers will enjoy self-check-in because it allows them to free up staff to do other, more challenging tasks. A case study performed by Kaiser Permanente found that 75 percent of patients felt that “checking in through the kiosk is faster than checking in through a receptionist.”

Touchscreen devices can be used to ask screening questions. Before an appointment even begins, more information can be gathered by asking additional follow-up questions based on the initial response. For example, a patient who answers “yes” to a question about flu symptoms can then be asked whether he or she received that year’s flu vaccine.

From small clinics to major hospital systems, providers often encounter patients who are most comfortable in a language other than English. A touchscreen device allows them to select their preferred language when checking in, then fill out the intake forms accordingly.

For patients who speak a less-common language, or who have lower literacy levels, visual cues and symbols can also be used to help guide them through the process, as recommended by the US Department of Health and Human Services.

In years gone by, medical staff had to spend valuable time on data entry, copying handwritten patient information from intake forms into a computer so that it could be stored as part of electronic medical records (EMR).

With an electronic check-in kiosk, patients can use the touchscreen to enter their data with an on-screen keyboard. There are two advantages to this process: one, information can flow directly into the provider’s EMR system, populating the patient’s file. This frees medical staff up to do other tasks. The second benefit is that when patients enter their information directly, using a keyboard, providers bypass the inevitable errors that come with deciphering handwriting.

An additional benefit of using touchscreen technology for the check-in process is that providers can incorporate key information or advice for the patient population.

For example, during flu season, providers can include a screen that informs patients of the availability of flu shots within their facility and another one reminding them of the availability of hand sanitizer.

The use of a touchscreen device paired with flexible, easy-to-use software means that messages can be quickly modified to deal with emerging situations. They can also be customized by departments so that visitors to the maternity wing get a different message from those checking into the emergency room.

When setting up a patient check-in system, there are two aspects that health care providers need to consider. The first is the patients’ desire for privacy when talking about sensitive health issues. The second is the rules and regulations that govern the handling of personal health information (PHI) to ensure that any patient’s information is kept confidential from anyone who doesn’t need to see it as part of treatment.

One benefit of using touchscreen devices for patient check-in is that patients may prefer not to have to verbally disclose or clarify information that they may find embarrassing or personal.

However, touchscreen devices offer an additional advantage when it comes to protecting personal health data: by eliminating peripherals such as keyboards and mice, they are less vulnerable to attack from those looking to compromise electronic records systems.

Additionally, check-in kiosks can be set up in a variety of ways to maximize patient privacy while checking in. Some providers install touchscreen devices inside individual carrels to provide patients with an additional layer of security. Another option is the installation of a privacy filter which prevents other people in the vicinity from being able to read the screen.

Hospitals and clinics have many employees coming in and out, and both physical security (for staff as well as patients) and information security are paramount. Using touchscreen technology to set up check-in kiosks for contractors and employees alike offers many benefits from an administrative perspective.

The touchscreens at an employee check-in kiosk can be used for a variety of purposes. When an employee signs in to a facility, the kiosk can also be used to scan their identification or snap a picture to create a temporary badge. Kiosks can also be used for time-tracking purposes so that employees’ work hours can be recorded for payroll.

Touchscreen technology can also be used to gather information about outside vendors and contractors. Hospitals, clinics, and doctors’ offices often have vendors entering to meet with employees, make deliveries, and fulfill other necessary duties. Connecting a touchscreen device to credential management software allows providers to ensure that vendors and contractors meet any requirements they have established, from having completed a background check to having received the necessary vaccinations.

Employee engagement isn’t just nice to have. Studies have shown that engaged employees perform better, leading to better clinical outcomes. A Gallup study once found that nurse engagement is the top predictor of variations in mortality rates across hospitals.

Touchscreen devices can be used to increase employee engagement in a variety of ways. Just as patient-facing kiosks might incorporate screens with health tips or other advice, employee-facing kiosks can also display pertinent information. For example, the employee check-in process might include screens highlighting standout employees, information on new benefits available, or even a survey question designed to assess employee satisfaction.

Employees can also use kiosks to get round-the-clock access to HR information. In a clinical environment, where employees work a variety of different schedules that often don’t overlap with regular office hours, immediate access to information about benefits, time off, scheduling, and more is vital.

Touchscreen technology is often used as part of the wayfinding and check-in process, but it also has a role to play when a patient has already been admitted to the hospital.

A touchscreen monitor can be installed in patient rooms within a hospital setting, or in exam rooms at a doctor’s office or urgent care clinic. These touchscreen devices can be used to communicate information about a patient’s condition from one employee to another when a shift changes, increasing consistency in care.

An added benefit of touchscreen devices is that they incorporate a keyboard, allowing for typed rather than handwritten text. As healthcare providers reach the end of a shift, their hands get tired from having to write so much, and their handwriting gets messier, leading to increased requests for clarification and even causing medical errors.

Touchscreen technology can also be used to quickly display medical imagery for the benefit of both the patient and other providers. Without needing peripherals such as a keyboard or a mouse, providers can pull up records, exam results, or images and zoom in so that everyone can see key information. They can even use their finger to draw on the image, calling attention to whatever they need a viewer to focus on.

Where do touchscreen devices fit in? Touchscreen technology can be leveraged as part of the inpatient experience by fitting patient beds with touchscreen devices. Different applications can be integrated into this device, so that a patient might be able to order a meal, call for a nurse, or change the TV channel, all without moving from their bed.

These same touchscreen devices can also be used to display information that’s relevant to patients based on their condition. New mothers staying in the maternity wing of a hospital might see information on the hospital’s breastfeeding group; patients recovering from major surgery might be able to watch a video about wound care.

Portable touchscreen devices can cut back on paperwork by allowing providers to obtain digital signatures from patients using a stylus. Clinical staff can also use the highlighter function to call patients’ attention to critical sections of the documents they’re signing.

There’s another benefit to handling documents digitally: when documents are never printed out in the first place, there’s less risk of exposing personal health information if a paper isn’t properly disposed of.

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.

As the COVID-19 pandemic rages across the globe, cleaning touch panel surfaces for users" peace of mind has become necessary because the virus can remain viable on surfaces for hours to days. Depending on type and model, AMT has compiled cleaning methods that we will share with you. We recommend carefully using only certain chemicals to clean both AMT projected capacitive (PCAP) and resistive touch panels.

According to US CDC, alcohol and bleach can be used to clean frequently touched surfaces. AMT has a rigorous testing structure for certifying the materials used in our products are suitable in terms of performance, durability, reliability, etc. The touch surface of AMT PCAP and resistive touch panels can withstand both industrial chemicals and household products such as acetone, hexane, laundry detergent, etc.

Ammonia based glass cleaners (typically 5 - 10% ammonia), 1: 100 bleach: water solution, or 75% alcohol can be used to clean the surface of AMT PCAP and resistive touch panels.

● Cleaning solutions containing bleach, alcohol, and ammonia are corrosive to touch panel surface coatings and ITO film. So, you should not leave the solution on the touch panel surface for more than 2 minutes. Make sure to remove all residue when finished cleaning.
