Imagine not being able to touch a touch-screen device.
Tablets and smartphones—with all their educational, entertaining and social
benefits—would be useless.
Researchers at Georgia Tech are trying to open the world of
tablets to children whose limited mobility makes it difficult for them to
perform the common pinch and swipe gestures required to control the devices.
Ayanna Howard, professor of electrical and computer
engineering, and graduate student Hae Won Park have created Access4Kids, a
wireless input device that uses a sensor system to translate physical movements
into fine-motor gestures to control a tablet.
