Patent ID: 11138301

Abstract:
A system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, an infrared emitter, and an infrared camera. The infrared emitter and the infrared camera are connected to the frame or the temple to emit a pattern of infrared light. The system includes a processor coupled to the eyewear device, a memory accessible to the processor, and programming in the memory. Execution of the programming by the processor configures the system to perform functions, including functions to emit, via the infrared emitter, a pattern of infrared light on an eye of a user of the eyewear device; capture, via the camera, reflection variations in the pattern of infrared light on the eye of the user; and identify a user of the eyewear device based on the reflection variations of the emitted pattern of infrared light on the eye of the user.
