ABSTRACT:
A technique for monitoring the reactions of a person exposed to a scene to determine the locations within such scene which attract the person's attention. A portable unit is mounted on the person's head by way of, for example, a set of earphones. A directional transmitter in the portable unit is aimed in the direction of the person's line of sight. Distributed throughout the scene are receivers located at selected points. When the person looks in the direction of one of these receivers, the emitted signal is detected by one of the receivers. An electronic memory stores the detected signal to indicate which of the receivers, and therefore which scene location, was being viewed.
