Non-line-of-sight radar-based gesture recognition
First Claim
1. A smart device associated with a radar field, the smart device comprising:
- a non-line-of-sight gesture-recognition system configured to;
provide the radar field, the radar field including a direct radar field and a reflected radar field, the reflected radar field provided in one or more volumes in a room to which direct line-of-sight from the non-line-of-sight gesture-recognition system is not available;
sense radar reflections from an interaction that is within the reflected radar field, the radar reflections sensed by receiving the radar reflections from a surface of the room and at an antenna of the non-line-of-sight gesture-recognition system;
recognize, based on the radar reflections from the interaction that is within the reflected radar field, a gesture; and
determine that the gesture is associated with a non-line-of-sight smart device; and
a transceiver or network interface configured to pass the gesture from the smart device associated with the radar field to the non-line-of-sight smart device in a format usable by the non-line-of-site smart device to recognize the gesture and effective to enable the gesture to control the non-line-of-sight smart device or establish communication with the non-line-of-sight smart device.

Abstract
This document describes techniques and devices for non-line-of-sight radar-based gesture recognition. Through use of the techniques and devices described herein, users may control their devices through in-the-air gestures, even when those gestures are not within line-of-sight of their device'"'"'s sensors. Thus, the techniques enable users to control their devices in many situations in which control is desired but conventional techniques do permit effective control, such as to turn the temperature down in a room when the user is obscured from a thermostat'"'"'s gesture sensor, turn up the volume on a media player when the user is in a different room than the media player, or pause a television program when the user'"'"'s gesture is obscured by a chair, couch, or other obstruction.

10. A smart device associated with a radar field, the smart device comprising:
-
a non-line-of-sight gesture-recognition system configured to; provide the radar field; sense radar reflections from an interaction that is within the radar field; recognize, based on the radar reflections from the interaction that is within the radar field, a gesture; and determine that the gesture is associated with a non-line-of-sight smart device; and a transceiver or network interface configured to; pass the gesture from the smart device associated with the radar field to the non-line-of-sight smart device in a format usable by the non-line-of-site smart device to recognize the gesture and effective to establish communication with the non-line-of-sight smart device; and establish communication with the non-line-of-sight smart device responsive to a determination that the gesture is for establishing communication with the non-line-of-sight smart device to enable control of the non-line-of-sight smart device through a future gesture determined at the smart device and sensed through the non-line-of-sight gesture-recognition system of the smart device. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system comprising:
-
a non-line-of-sight gesture-recognition system configured to; provide a radar field within a room, the radar field including reflected radar fields, the reflected radar fields being reflected off of one or more surfaces of the room and provided in one or more volumes in the room to which direct line-of-sight from the non-line-of-sight gesture-recognition system is not available; and receive a radar reflection of a gesture interaction made within the one or more volumes in the room to which direct line-of-sight from the non-line-of-sight gesture-recognition system is not available, the radar reflection enabling capture of data about the gesture interaction, one or more processors; and one or more computer readable storage media having instructions stored thereon that, responsive to execution by the one or more processors, implement a system manager, the system manager configured to; determine a gesture based on the data about the gesture interaction; and provide the gesture to a device or application effective to control the device or application. - View Dependent Claims (17, 18, 19, 20)
