Abstract: A wearable device with an optical sensor is disclosed that can be used to recognize gestures of a user wearing the device. Light sources can be positioned on the back or skin-facing side of a wearable device, and an optical sensor can be positioned near the light sources. During operation, light can be emitted from the light sources and sensed using the optical sensor. Changes in the sensed light can be used to recognize user gestures. For example, light emitted from a light source can reflect off a wearer's skin, and the reflected light can be sensed using the optical sensor. When the wearer gestures in a particular way, the reflected light can change perceptibly due to muscle contraction, device shifting, skin stretching, or the distance changing between the optical sensor and the wearer's skin. Recognized gestures can be interpreted as commands for interacting with the wearable device.
