Classification: CPC G | IPC G

Claim 16:
17. A wearable electronic device comprising:
a housing;
photodiodes disposed within the housing;
a set of light emitters configured to emit light;
a processor configured to:
cause a prompt for a user to perform a first type of gesture;
after prompting to perform the first type of gesture and during a first time period:
emit first light from the set of light emitters and toward the user from a portion of the wearable electronic device facing the user;
collect first sensor data from the photodiodes, the first sensor data based on a portion of the emitted first light reflected from the user;
determine a first set of signal characteristics from the first sensor data, the first set of signal characteristics corresponding to movement performed by the user in response to the prompt to perform the first type of gesture; and
assign the first set of signal characteristics to the first type of gesture;

cause a prompt for the user to perform a second type of gesture;
after prompting the user to perform the second type of gesture and during a second time period:
emit second light toward the user from the portion of the wearable electronic device facing the user;
collect second sensor data from the photodiodes, the second sensor data based on a portion of the emitted second light reflected from the user;
determine a second set of signal characteristics from the second sensor data, the second set of signal characteristics corresponding to movement performed by the user in response to the prompt to perform the second type of gesture; and
assign the second set of signal characteristics to the second type of gesture.
