![]() ![]() They may be able to locate and activate controls if they are labeled in a large high-contrast font, if there is a least one tactile reference point to provide orientation, and/or if audible output is provided to help identify the controls. ![]() At the same time, people who are blind or have low vision can successfully use touch screens on their Android and/or iOS platform mobile phones. These applications typically include large icons and a simple intuitive design layout.ĭespite advantages to some, however, touch screens can present barriers to others, such as people with physical disabilities who are unable to touch the device, as well as people with low vision and blindness, for whom the device provides no controls that can be appreciated by sense of touch. Specially designed applications have also been developed specifically for touch screen use. In fact, touch screens have been used as assistive technology for many years, providing an alternative to standard input devices for users who need access to standard applications. Since touch screens were designed to provide user-friendly, intuitive computer access without requiring a keyboard and mouse, it logically follows that touch screens can be excellent tools for people who experience difficulty using keyboards and mice because of physical or cognitive disabilities. Researchers are actively exploring ways to further integrate touch screens more fully into educational environments, such as building touch screen functionality into walls, student desks, and other objects in the learning environment. In elementary schools, students who don't have keyboard and mouse skills can use touch screens to access rich computer-based content. ![]() In the field of education, touch screen stations are installed in K-12, postsecondary, and corporate learning environments to facilitate interaction between the learner and the content to be learned. It is important to note that some gestures are slightly different for blind/visually impaired individuals who use screen readers such as Android’s TalkBack or Apple’s VoiceOver screen readers, combined with touch input. The learning curve can initially seem daunting, but many people overcome it to become quite proficient. Touch screens are certainly the most common means of input into mobile phones. Touch screens today are frequently used for information kiosks, automated teller machines (ATMs), airline e-ticket terminals, and customer self-service stations in retail stores, libraries, and fast food restaurants. A touch screen is a computer display screen that is sensitive to human touch, allowing a user to interact with the computer by touching pictures or words on the screen. ![]()
