A VERSATILE RECORDER OF VISUAL POINT OF REGARD
The construction of a low cost fairly accurate recording equipment of visual point of regard is described. The technique is based on optical mixing on the head of cornea reflex and field of view. The optic parts are fastened rigidly to the head by means of individual helmet and upper jaw support. There are several calibration possibilities, manual as well as by remote control. The image is transported from the head by means of a flexible optic fibre cable and recorded on a video tape recorder.
