Radar chart with the 7 axis of a design space. Talkback and VoiceOver representations completly overlap with the exception of the Output axis: VoiceOver uses implicit while TalkBack uses explicit output.

Nonvisual Word Completion

We investigate novel interfaces and interaction techniques for nonvisual word completion. We are particularly interested in quantifying the benefits and costs of such new solutions.

Someone holding a smartphone with both hands. The device is inside a custom case that has 3 small vibrotactile motors on top and bottom. These motors are in contact with the user's fingers.

Multi-point Vibrotactile Feedback

As touchscreens have evolved to provide multitouch capabilities, we are exploring new multi-point feedback solutions.
