Gesture component with gesture library

A computing device comprising:

• a processing system;
• an application maintained in computer-readable storage media and executable by the processing system to perform a plurality of operations;
• and
• a gesture component implemented at least partially in hardware, the gesture component including:
• a three-dimensional object detection module configured to detect an input involving orientation or movement of an object in three-dimensional space, the detection based on received radar signals that have been reflected by the object;
• and
• a gesture module configured to:
• maintain a library of gestures;
• transform raw data corresponding to the radar signals into one or more different representations that represent shape information about the object;
• extract three-dimensional feature information about the object from the transformed raw data of the radar signals;
• compare the three-dimensional feature information about the object from the transformed raw data of the radar signals with the library of gestures;
• recognize a gesture performed by the object based on the comparison;
• and
• expose an indication of at least one said operation that corresponds to the recognized gesture via an application programming interface for receipt by at least one application to cause the at least one application to control performance of the at least one said operation.

A method of controlling operation of a computing device based on gesture detection, the method comprising:

• transmitting a plurality of outgoing radio frequency radar signals by a gesture component;
• capturing incoming radio frequency radar signals generated by the plurality of outgoing radio frequency radar signals as reflecting off a user;
• generating an input by the gesture component from the captured incoming radio frequency radar signals, the input generated by:
• transforming raw data corresponding to the incoming radio frequency radar signals into one or more different representations that represent shape information about one or more portions of the user;
• extracting three-dimensional feature information about the one or more portions of the user;
• comparing the three-dimensional feature information about the one or more portions of the user with a library of gestures maintained by the gesture component;
• recognizing a gesture performed by the one or more portions of the user based on the comparison;
• and
• exposing an indication of at least one operation that corresponds to the recognized gesture by the gesture component via an application programming interface for receipt by at least one application executed by the computing device to cause the at least one application to control performance of the at least one operation.
