A method and system for generating a dynamic, real time synchronized display of individual visual fixation points of one or more viewers superimposed on a video taped visual presentation for subsequent evaluation to assess the effectiveness of such visual presentation in communicating information.

Method and system for generating a synchronous display of a visual

A head-mounted, eye-movement, measurement system is provided with an optically flat glass laminated visor through which the observer views the external scene. Mounted so as to be vertically spaced from one side of the eye's optic axis is an eye tracker module for recording the observer's eye-movement relative to the head, principally by measuring the position of the pupil and corneal reflex, by reflecting near infrared light to and from the observer's eye vis-a-vis the front surface of the visor. Mounted so as to be vertically spaced on the opposite side of the eye's optic axis is a field-of-view camera which records the external scene viewed by the observer by reflecting external scene light from the back side of the visor. The distances and angular relationship of the visor, camera and eye are controlled to eliminate parallax from the field-of-view camera while also providing a stable arrangement permitting wide-angle scene viewing and accurate recordal of eye movements.
