Abstract

Eye blinks elicited by a mechanically produced tap to the glabella (the flattened area between the eyebrows) are monitored by a device that projects low-intensity infrared light, which is reflected from the eyelid and detected by a phototransistor. Appropriate filtering and decoding circuitry insures reliable tracking of responses. Comparison of the optical eye blink monitor with a minitorque potentiometer monitor showed the two devices to yield similar recordings.
