Abstract
Various embodiments wirelessly detect micro gestures using multiple antenna of a gesture sensor device. At times, the gesture sensor device transmits multiple outgoing radio frequency (RF) signals, each outgoing RF signal transmitted via a respective antenna of the gesture sensor device. The outgoing RF signals are configured to help capture information that can be used to identify micro-gestures performed by a hand. The gesture sensor device captures incoming RF signals generated by the outgoing RF signals reflecting off of the hand, and then analyzes the incoming RF signals to identify the micro-gesture.
Claims40
A method comprising:
- receiving, by a computing device, a plurality of incoming radio frequency (RF) signals generated by at least one outgoing RF signal reflecting off a target object;
- processing, by the computing device, a set of data originating from the incoming RF signals to extract millimeter-scale information about the target object;
- and
- processing, by the computing device, the millimeter-scale information about the target object to identify a micro gesture performed by the target object.
A device configured to identify a micro gesture performed by a target object, the device comprising:
- a processor;
- and
- a computer-readable media comprising instructions that, when executed by the processor, cause the device to:
- receive a plurality of incoming RF signals generated by at least one outgoing RF signal reflecting off the target object;
- generate signal data corresponding to the incoming RF signals;
- determine, based on the signal data, that the target object has performed the micro gesture, the micro gesture being on a millimeter scale;
- and
- output an indication of the micro gesture.
