Radar-Based Gesture-Recognition through a Wearable Device
First Claim
Patent Images
1. A radar-based gesture-recognition system comprising:
- a microwave radio element configured to provide a localized radar field;
an antenna element configured to sense an interaction having multiple targets in the localized radar field; and
a signal processor configured to process the sensed interaction having the multiple targets in the localized radar field sufficient to provide gesture data usable to determine a gesture from the sensed interaction having the multiple targets.

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.

10. A computer-implemented method comprising:
-
determining, for an application on a computing device, a set of controls through which the application can be controlled; indicating the set or a subset of the controls selectable through a localized radar field; causing a radar-based gesture-recognition system to present the localized radar field; causing the radar-based gesture-recognition system to sense an interaction in the localized radar field; determining a control of the set or subset of the controls selected through the sensed interaction in the localized radar field; and passing the determined control to the application. - View Dependent Claims (11, 12)

13. A wearable computing device comprising:
-
a radar-based gesture-recognition system configured to sense gestures; 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 a localized radar field; causing the radar-based gesture-recognition system to sense an interaction in the localized radar field; determining a gesture based on the sensed interaction in the localized radar field; and passing the determined gesture to an application or operating system of the wearable computing device effective to cause the application or operating system to receive an input corresponding to the determined gesture. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
