US Patent 11908356 Augmented reality display device having contextual adaptive brightness

An electronic device, computer program product, and method present augmented reality (AR) imagery at an AR display device with contextual, adaptive brightening control. The AR display device includes eyeglasses having lenses positioned in front of eyes of a person. A first camera sensor detects ambient light. An AR projector displays AR imagery on the lenses. A second camera sensor is configured to detect whether the eyes of the person are open or closed. A controller of the electronic device is communicatively coupled to the AR display device. The controller detects brightness of the ambient light. The controller dynamically adjusts brightness of the AR imagery in relation to the brightness of the ambient light. The controller reduces the brightness of the AR imagery in response to determining a brightness context that the eyes of the person have been closed for longer than threshold period of time.
