A new eye movement analyzer: auto calibration and wireless transmission

摘要

An eye movement analyzer was developed for analyzing eye movements and superimposing the observer's line of sight on a TV image corresponding to his or her view. The eye-movement detection unit is compact in size and weighs only 1.2 kg. Eye-movement data are multiplexed onto the vertical blanking interval of the field-of-view video signal and transmitted on UHF. The processing system which is used to analyze the eye movements and processes the TV image is also compact and easy to carry. Calibration is automatic and completed within 1 min with a high degree of accuracy.
