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.
Claims20
A computer-implemented method comprising:
- detecting a microwave radar signal reflected from a portion of a person, the person known to be permitted gesture-based control of a mobile computing device;
- determining, based on the detected microwave radar signal, an identifying indicia for the portion of the person;
- and
- recording the identifying indicia effective to enable a later-detected microwave radar signal to authenticate the person for gesture-based control of the mobile computing device.
A computer-implemented method comprising:
- detecting, at a mobile computing device, a microwave radar signal through one or more occlusions, the microwave radar signal penetrating through the one or more occlusions;
- determining, based on the detected microwave radar signal, identifying indicia of a person making an occluded gesture;
- authenticating, based on the determined identifying indicia, the person making the occluded gesture;
- and
- enabling the person to control the mobile computing device via the occluded gesture.
An apparatus comprising:
- an occluded-gesture recognition system comprising a microwave radio element configured to receive a microwave radar signal through an occlusion;
- 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:
- detecting, based on the received microwave radar signal, a gesture performed by a person;
- determining, based on the received microwave radar signal, identifying indicia of the person performing the detected gesture;
- authenticating the person based on the identifying indicia;
- and
- responsive to authenticating the person, enabling the detected gesture to control an entity associated with the apparatus.
