Novel User Interfaces

Multiwave: Complex Hand Gesture Recognition Using the Doppler Effect

We built an acoustic, gesture-based recognition system called Multiwave, which leverages the Doppler Effect to translate multidimensional movements into user interface commands.

Multiwave: Doppler Effect Based Gesture Recognition in Multiple Dimensions

We present the results of a user study of Multiwave to evaluate recognition rates for different gestures and report accuracy rates comparable to or better than the current state of the art.
