Eye movement evoked by a video image composed of the global motion vector

Abstract

To evaluate biomedical effects of the motion in the video image evoked by camera works, the motion components in the video image should be extracted, and their effects on physical parameters should be tested independently. As the first step of this effort, eye movement evoked by viewing a CG movie composed of a series of the motion vector, which were extracted from a real image, was compared with that evoked by viewing the original real image. The CG movie was composed of a randomly distributed dots, which were provided with a series of global vectors calculated from the movement of the corresponding points of the real image, and was presented on a 80 inch screen by liquid crystalline projectors. Eye movement was measured by using an infrared computer-assisted eye/pupil meter. 4 subjects were given informed consents. Eye movements evoked by the composite motion random dots had slow movement components, which were well comparable with those evoked by the real image, while fast components were quite different.
