Abstract
A system may include one or more finger devices that gather input from a user's fingers. The system may include control circuitry that sends control signals to an electronic device based on the input gathered with the finger devices. A finger device may include one or more proximity sensors that measure a distance to the user's finger. The proximity sensor may be a self-mixing optical proximity sensor having a laser and photodiode. The proximity sensor may have submicron resolution and may be configured to detect very small movements of the finger as finger pad is moved around by a thumb finger, by a surface, and/or by other finger movements. The proximity sensor may measure changes in distance between the proximity sensor and a flexible membrane that rests against a side portion of the user's finger.
