Abstract

To produce a control signal in response to closure of the eye, a visible light transmitter 15 and receiver 16 are mounted on a spectacle frame or similar so as to be situate above and in front of the eye. Conductors 19 are connected to a control circuit arranged to supply modulated current to the transmitter 15 and to respond to changes in light levels received by the receiver 16. The open eye reflects little light, but the scattering effect of the eyelid when the eye is closed reflects a greater amount of light to the receiver 16. Comparing the phase of the transmitted and received light allows effects of ambient light to be eliminated, and a delay circuit discriminates deliberate eye closure from blinking. A computer may display a sequence of characters on a visual display unit and respond to the control signal so as to store for further processing e.g. printing the character being displayed at the time. The control signal may control other equipment e.g. a wheelchair. <IMAGE>
