Radar-Based Gesture-Recognition at a Surface of an Object
First Claim
Patent Images
1. A radar-based gesture-recognition system comprising:
- a microwave radio element that emits microwave radiation to provide a localized radar field conforming to a surface of an object;
an antenna element that senses interactions at the surface of the object and within the localized radar field;
one or more processors; and
one or more computer-readable storage media having instructions that, when executed, cause the one or more processors to;
differentiate, based on the interactions sensed by the antenna element, user interactions caused by human tissue from other interactions that are not caused by human tissue;
determine, based on the user interactions and not the other interactions, a gesture performed at the surface of the object; and
output an indication of 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.

8. A method implemented by a radar-based gesture-recognition system comprising:
-
emitting, using a microwave radio element of the radar-based gesture recognition system, microwave radiation to provide a localized radar field conforming to a surface of an object; sensing, with an antenna element of the radar-based gesture-recognition system, interactions at the surface of the object and within the localized radar field; differentiating, from the sensed interactions, user interactions that are from human tissue from other interactions that are not from human tissue; determining, based on the differentiated user interactions that are from human tissue, a gesture performed at the surface of the object; and outputting data corresponding to the determined gesture. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable storage media having instructions that, when executed, cause the one or more processors to:
-
cause a microwave radio element to emit microwave radiation that provides a localized radar field conforming to a surface of an object; receive interactions sensed, with an antenna element, at the surface of the object and within the localized radar field; differentiate, from the sensed interactions, user interactions that are from human tissue from other interactions that are not from human tissue; determine, based on the differentiated user interactions that are from human tissue, a gesture performed at the surface of the object; and output data corresponding to the determined gesture. - View Dependent Claims (16, 17, 18, 19, 20)
