Abstract: In one example of the invention a patient display is provided on which a fixation graphic or video is shown in substantially the center of the display, and then target graphics or video are shown at different positions on the display about the center. A test subject is positioned in front of the patient display a known distance therefrom, and a camera captures an image of the test subject's eyes, to allow gaze direction determination to be performed. The captured images are displayed to a clinician user by a controlling test application, the clinician making a determination based on the images as to whether the test subject saw a target graphic or video when it was displayed. The clinician user then makes an appropriate input into the controlling test application, which also logs the position at which the target image was displayed.

Abstract: A method of displaying an image on a screen having upper and lower extremities to a viewer located in front of the screen and at a horizontal distance from the screen, the method comprising the steps of: (a) inclining the screen at an angle of 60° or less to a horizontal plane behind the screen; (b) arranging the viewer and screen such that the upper extremity of the screen is further away than its lower extremity from the point of view of the viewer with said upper extremity above the head height of the viewer; and, (c) displaying the image on the screen.
