1. A computer-implemented method comprising:
- authenticating a person permitted to control a mobile computing device based on authentication credentials;
providing a radar field using microwave radiation;
receiving, via the provided radar field, a reflection from a hand of the authenticated person;
determining identifying indicia for the hand of the authenticated person based on the received reflection;
recording the identifying indicia effective to enable a later-received radar field reflection from the hand to be identified as being from the authenticated person;
determining a hand gesture of the authenticated person'"'"'s hand based on the received reflection;
mapping the determined hand gesture to a control input; and
recording the mapping of the determined hand gesture effective to enable a later-received hand gesture to be mapped to the control input.

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.

-
authenticating a person permitted to control a mobile computing device based on authentication credentials; providing a radar field using microwave radiation; receiving, via the provided radar field, a reflection from a hand of the authenticated person; determining identifying indicia for the hand of the authenticated person based on the received reflection; recording the identifying indicia effective to enable a later-received radar field reflection from the hand to be identified as being from the authenticated person; determining a hand gesture of the authenticated person'"'"'s hand based on the received reflection; mapping the determined hand gesture to a control input; and recording the mapping of the determined hand gesture effective to enable a later-received hand gesture to be mapped to the control input. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A computer-implemented method comprising:
-
providing, at a mobile computing device, a radar field through one or more occlusions, the radar field having microwave radiation effective to penetrate through the one or more occlusions; receiving, at the mobile computing device, a reflection from an occluded gesture within the radar field; determining, based on the received reflection, identifying indicia of a person making the occluded gesture; determining, based on the identifying indicia, that the person making the occluded gesture is permitted to control the mobile computing device; recognizing the occluded gesture based on the received reflection; determining a control input associated with the recognized gesture; and passing the determined control input effective to control an entity associated with the mobile computing device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. An apparatus comprising:
-
an occluded-gesture recognition system comprising a microwave radio element configured to provide a radar field having microwave radiation; 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 a gesture actor interacting with the radar field provided by the occluded gesture recognition system; determining, based on a reflection from the radar field, identifying indicia for a person associated with the gesture actor; identifying, based on the identifying indicia, the person associated with the gesture actor; determining that the identified person is permitted to control the apparatus; and responsive to determining that the identified person is permitted to control the apparatus, passing a control input determined, based on the interaction or another interaction by the gesture actor with the radar field, to an entity associated with the apparatus, the passing of the control input effective to control the entity. - View Dependent Claims (18, 19, 20)
