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.
The device, coupled with supporting open-source apps and software developed at Georgia Tech, allows children with fine motor impairments to access off-the-shelf apps such as Facebook and YouTube, as well as custom-made apps for therapy and science education.
