Occluded Gesture Recognition
First Claim
Patent Images
1. A method performed by a smartphone, the method comprising:
- determining that the smartphone is in a location corresponding to a pocket of a user based on sensor data provided by at least one sensor;
providing a radar field emanating through an occlusion from inside the pocket to outside the pocket, the radar field encompassing a likely location where a gesture is to be made with the user'"'"'s hand;
producing an audible sound;
receiving, through the occlusion, a human-tissue reflection of the gesture performed by the user'"'"'s hand;
recognizing, based on the human-tissue reflection, that the gesture is associated with a control input to mute the smartphone; and
muting the audible sound responsive to recognizing the gesture.

Abstract
This document describes techniques and devices for occluded gesture recognition. Through use of the techniques and devices described herein, users may control their devices even when a user'"'"'s gesture is occluded by some material between the user'"'"'s hands and the device itself. Thus, the techniques enable users to control their mobile devices in many situations in which control is desired but conventional techniques do permit effective control, such as when a user'"'"'s mobile computing device is occluded by being in a purse, bag, pocket, or even in another room.

1. A method performed by a smartphone, the method comprising:
-
determining that the smartphone is in a location corresponding to a pocket of a user based on sensor data provided by at least one sensor; providing a radar field emanating through an occlusion from inside the pocket to outside the pocket, the radar field encompassing a likely location where a gesture is to be made with the user'"'"'s hand; producing an audible sound; receiving, through the occlusion, a human-tissue reflection of the gesture performed by the user'"'"'s hand; recognizing, based on the human-tissue reflection, that the gesture is associated with a control input to mute the smartphone; and muting the audible sound responsive to recognizing the gesture. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A smartphone comprising:
-
a speaker configured to produce an audible sound; at least one sensor configured to produce sensor data; an occluded-gesture recognition system configured to; determine that the smartphone is in a pocket of a user based on the sensor data provided by the at least one sensor; provide a radar field emanating through an occlusion from inside the pocket to outside the pocket, the radar field encompassing a likely location where a gesture is to be made with the user'"'"'s hand; receive, through the occlusion, a human-tissue reflection of the gesture performed by the user'"'"'s hand after the speaker produces the audible sound; and recognize, based on the human-tissue reflection, that the gesture is associated with a control input to mute the smartphone; and a gesture manager configured to; mute the audible sound responsive to accepting the control input from the occluded-gesture recognition system. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A smartphone comprising:
-
a speaker configured to produce an audible sound; at least one sensor configured to produce sensor data; an occluded-gesture recognition system configured to; receive, through an occlusion, a human-tissue reflection of a gesture performed by a user'"'"'s hand after the speaker produces the audible sound, the human-tissue reflection occurring at a likely location where a gesture is to be made with the user'"'"'s hand; 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; determining that the smartphone is in a pocket of the user based on the sensor data; recognizing, based on the human-tissue reflection, that the gesture is associated with a control input to mute the smartphone; and muting the audible sound responsive to recognizing the gesture. - View Dependent Claims (17, 18, 19, 20)
