Abstract

The eye movement monitor measures both vertical and horizontal eye movements by employing an optoelectronic noncontact technique with a high updates rate. The monitor is controlled by an IBM AT or compatible computer and basically consists of a sensor assembly and two cards, connected to the PC bus: an amplifier and synchronous detection unit and a 12 bit AD/DA converter. The sensor assembly is mounted to spectacle frames and connected with the computer by a flexible cable. All the measurement data are stored in the hard disk and can be represented as vertical and horizontal coordinates of the gaze at selected time moments. The monitor does not interfere with the subject's head movements nor does it obstruct significantly his view of vision. The pulsed bias and synchronous detection make the device insensitive to the background illumination artifacts.
