Unigest

This paper introduces UniGest, a technique that provides pointer input and text entry in a single device without occupying the display. It uses a Nintendo Wii motion-sensing remote to capture gestures that are mapped to character input. A gesture alphabet is proposed, with each gesture composed of at most two primitive motions. A web-based user study measured movement times for primitive motions. Results range from 296 to 481 ms, implying an upper-bound UniGest text entry performance prediction of 27.9 wpm.
