Abstract :
The remote oculometer is a new instrument for the remote measurement of eye direction and pupil diameter. The electrooptical sensor unit is located several feet from the subject, who is free to move the eye being sensed throughout 1 ft3 of space. The video processing is performed in real time by a standard minicomputer. The oculometer processor (minicomputer) provides automatic calibration and linearization to each subject and can, supply the output eye-direction information in the form of either fixation-point coordinates on any specified fixation plane, azimuth and elevation, or direction cosines.The oculometer measures line-of-sight to an accuracy of 1° for eye rotation angles, relative to the sensor unit, of from 0° to + 30° elevation and from -30 ° to + 30 ° azimuth.
