1. A system comprising:
- a radar-based gesture-recognition system configured to sense gestures, the radar-based gesture-recognition system comprising;
(1) a microwave radio element configured to emit microwave radiation capable of substantially penetrating clothing and not substantially penetrating human tissue, and(2) an antenna element or signal processor configured to differentiate gesture interactions caused by clothing from gesture interactions caused by human tissue;
one or more computer processors; and
one or more computer-readable storage media having instructions stored thereon that, responsive to execution by the one or more computer processors, perform operations comprising;
causing the radar-based gesture-recognition system to provide, using the microwave radio element, a localized radar field adjacent the system, the localized radar field corresponding to a surface radar field on which an interaction is sensed, the surface radar field conforming to a surface of an object and being divided into selectable control regions;
causing the radar-based gesture-recognition system to sense the interaction on the surface radar field, the interaction interrupting one or more of the selectable control regions of the surface radar field at or near the surface of the object;
determining a two-dimensional gesture or a three-dimensional gesture based on the sensed interaction on the surface radar field; and
outputting data corresponding to the determined gesture.

Abstract
This document describes techniques and devices for radar-based gesture-recognition through a wearable device. The techniques enable an easy-to-use input interface through this wearable radar device, in contrast to small or difficult-to-use input interfaces common to wearable computing devices. Further, these techniques are not limited to interfacing with wearable computing devices, but may aid users in controlling various non-wearable devices, such as to control volume on a stereo, pause a movie playing on a television, or select a webpage on a desktop computer.
