Eye movement monitoring apparatus
First Claim
1. Apparatus for determining the eye movements of a viewer in response to visual stimuli comprising:
- a screen for displaying said stimuli;
support means placed at a preselected distance in front of said screen for maintaining the viewer'"'"'s head in a relatively fixed position;
means for monitoring the viewer'"'"'s eye movements;
means for monitoring said stimuli displayed on the screen and placed in front of the torso of said viewer, said stimuli monitoring means extending generally parallel to said screen;
lens means aimed at said screen and attached to said stimuli monitoring means adjacent said support means and below viewer eye level for receiving light from said screen and for transmitting it into said image monitoring means; and
means for combining the outputs of both said monitoring means to superimpose the viewer'"'"'s eye movements on the displayed stimuli.

Abstract
An apparatus is disclosed for testing the eye movements of a viewer in response to visual stimuli, such as an advertisement, displayed on a screen. One camera cooperates with a light source to detect eye movements indicated by a light beam deflected off the viewer'"'"'s cornea. Another camera is placed parallel to the screen and in front of the viewer. A right-angle lens directs light from the screen into the camera. The outputs of the two cameras are combined to superimpose the viewer'"'"'s eye movements on the images displayed on the screen. A running time starting with the instant the advertisement is exposed to the viewer is also combined with the eye movement and screen presentations.

13. Apparatus for monitoring the eye movements of a viewer in response to visual stimuli and for measuring the amount of time spent by the viewer'"'"'s eye in a given position comprising:
-
a screen for displaying said visual stimuli; means for monitoring said screen; means for monitoring the viewer'"'"'s eye movements in response to said visual stimuli; timing means for providing a running time indication from the instant the visual stimuli is displayed to the viewer; and means for displaying the superimposed outputs from both of said monitoring means and said timing means. - View Dependent Claims (14, 15, 16, 17, 18)

19. Apparatus for testing the visual response of viewer to a visually displayed advertisement, comprising:
-
a. a screen for displaying said advertisement; b. means for monitoring the eye movements of said viewer in response to the displayed advertisement; c. a television camera placed in front of said viewer and generally parallel to said screen; d. a right-angle lens attached to said camera and positioned substantially directly below the eyes of said viewer and aimed at said screen; and e. means for combining the outputs of said monitoring means and said television camera to superimpose the eye movements of said viewer on said advertisement. - View Dependent Claims (20, 21, 22, 23, 24, 25)
