Eyelid Gesture

An eyelid gesture is a deliberate eye movement used as an input method for controlling digital devices, involving intentional opening and closing of one or both eyelids in specific patterns, sequences, and durations. Unlike simple blink detection, eyelid gestures exploit the independent control of left and right eyelids to create a richer vocabulary of commands. This interaction technique is particularly relevant for people with severe motor impairments such as spinal cord injuries or limb amputations, who may have limited or no use of their hands but retain reliable eyelid control.
