Which assistive technology enables students with limited motor control to interact with computers using simple button presses?

• A. Adaptive switches
• B. Color overlays
• C. OPAC (Online Public Access Catalog)
• D. Interactive Read Aloud

Answer: (A)

The idea here is access to computer activity with very minimal physical effort. Adaptive switches are input devices that translate a simple action (like pressing a large button or squeezing a switch) into a computer command, such as a mouse click or a keyboard press. For students with limited motor control, a single switch or a small set of switches can be used with scanning software so that repeatedly highlighting options on the screen and then pressing the switch selects the desired item. This makes it possible to interact with digital tools, catalogs, and educational apps without needing precise mouse movements or fast keyboarding. Color overlays change how text looks to improve readability but don’t provide a new way to input or control a computer. An OPAC is an online catalog used to search the library, not an input method for motor-impaired users. An Interactive Read Aloud is a feature that reads text aloud, which helps with access to content but again isn’t about enabling motor-control-based interaction with the computer. Adaptive switches best fit the scenario by giving a reliable, low-effort way to control a computer.
