First Claim
Patent Images
1. A device comprising:
- a plurality of light emitters configured to emit light at a tissue of a user;
a plurality of photodiodes configured to sense at least a portion of a reflection of the emitted light and generate sensor data indicative of movement of anatomic features in the tissue of the user;
a plurality of channels, each channel associated with one of the plurality of light emitters and one of the plurality of photodiodes and further associated with a signal pattern including the sensor data from the respective photodiode; and
logic configured to;
receive the signal patterns of the plurality of channels,determine signal characteristics from the signal patterns, anddetermine a hand gesture from the determined signal characteristics.

Abstract
This disclosure relates to detecting hand gesture input using an electronic device, such as a wearable device strapped to a wrist. The device can have multiple photodiodes, each sensing light at a different position on a surface of the device that faces skin of a user. Examples of the disclosure detect hand gestures by recognizing patterns in sensor data that are characteristic of each hand gesture, as the tissue expands and contracts and anatomical features in the tissue move during the gesture.

13. A method of determining a hand gesture, the method comprising:
-
emitting light from a plurality of light emitters at a tissue of a user; receiving at least a portion of a reflection of the emitted light using a plurality of photodiodes; generating sensor data from the received light, the sensor data indicative of movement of anatomic features in the tissue of the user; associating the plurality of light emitters and plurality of photodiodes with a plurality of channels; associating signal patterns included in the sensor data to the plurality of channels; determining signal characteristics from the signal patterns; and determining a hand gesture from the determined signal characteristics. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
