Systems, methods, and devices for utilizing radar-based touch interfaces

An electronic device comprising:

• a casing;
• a first processor coupled to a radar transceiver;
• a second processor coupled to a motion sensor;
• and
• memory coupled to the first and second processors, the memory storing one or more programs configured to be executed by the first and second processors, the one or more programs including instructions for:
• using the second processor:
• determining using signals from the motion sensor that an object is in proximity to the electronic device;
• and
• in accordance with determining that the object is in proximity to the electronic device, waking up the first processor;
• and
• using the first processor:
• enabling operation of the radar transceiver;
• receiving a set of signals associated with the operation of the radar transceiver, the set of signals indicating an amount of jitter of the object;
• determining that the object is in contact with the casing when the amount of jitter indicated in the set of signals is below a predetermined threshold;
• in accordance with determining that the object is in contact with the casing, identifying an input command based on at least one of:
• a location of the object, and a movement of the object;
• and
• adjusting operation of the electronic device based on the input command.

A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device located in a room, the electronic device having a casing, a first processor coupled to a radar transceiver, a second processor coupled to a motion sensor, and memory, cause the electronic device to perform operations comprising:

• using the second processor:
• determining using signals from the motion sensor that an object is in proximity to the electronic device;
• and
• in accordance with determining that the object is in proximity to the electronic device, waking up the first processor;
• and
• using the first processor:
• enabling operation of the radar transceiver;
• receiving a set of signals associated with the operation of the radar transceiver, the set of signals indicating an amount of jitter of the object;
• determining that the object is in contact with the casing when the amount of jitter indicated in the set of signals is below a predetermined threshold;
• in accordance with determining that the object is in contact with the casing, identifying an input command based on at least one of:
• a location of the object, and a movement of the object;
• and
• adjusting operation of the electronic device based on the input command.
