The screens on many mobile phones can leave a user feeling distinctly vision impaired, especially if her attention is divided between tapping virtual buttons and walking or driving. Fortunately, engineers at Google are experimenting with interfaces for Android-powered mobile phones that require no visual attention at all. Last week the company demonstrated an adaptive, circular interface for phones that provides audio and tactile feedback.
"We are building a user interface that goes over and beyond the screen," says research scientist T.V. Raman. Often, eyes-free interfaces are employed for blind users, but Raman, who himself is blind, assures that these interfaces have much broader implications. "This is not just about the blind user," he says. "This is about how to use these devices if you're not in a position to look at the machine."
