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 two or more portions of a user;
- processing, by the computing device, a set of data originating from the incoming RF signals to extract information about movements of each of the portions of the user;
- determining, by the computing device and based on the information about the movements of each of the portions of the user, a relative movement between the portions of the user;
- and
- processing, by the computing device, the relative movement between the portions of the user to identify a gesture performed by at least one of the portions of the user.
A device configured to identify a relative-movement 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 radio frequency (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 relative-movement gesture, the relative-movement gesture comprising a portion of the target object moving relative to another portion of the target object;
- and
- output an indication of the relative-movement gesture.
A device configured to identify a relative-movement 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 radio frequency (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 and using at least one machine-learning algorithm, that the target object has performed the relative-movement gesture, the relative-movement gesture comprising a portion of the target object moving relative to another portion of the target object;
- and
- output an indication of the relative-movement gesture.
A device configured to identify a relative-movement gesture performed by a target object, the device comprising:
- at least one transmit antenna;
- a plurality of receive antennas;
- a processor;
- and
- a computer-readable media comprising instructions that, when executed by the processor, cause the device to:
- receive a plurality of incoming radio frequency (RF) signals generated by at least one outgoing RF signal reflecting off the target object, each of the incoming RF signals received by one of the receive antennas;
- generate signal data corresponding to the incoming RF signals;
- determine, based on the signal data, that the target object has performed the relative-movement gesture, the relative-movement gesture comprising a first portion of the target object moving relative to a second portion of the target object;
- and
- output an indication of the relative-movement gesture.
