Abstract
An eye pointer was developed as a new line-of-sight displacement analyser. It analyses an observer's eye movements and superimposes their line of vision on a TV image which is the same as their view. A newly developed miniature colour field camera and very compact eye-movement sensors are attached to a translucent reinforced plastic goggle affording a wide view and excellent safety. A small case is provided for the eye-movement detecting circuit and the camera controller unit etc. Its weight is only 1·2 kg and one can easily participate in sports activities while wearing it. Eye-movement data are transmitted with the VHF video signal. The receiver, which analyses the eye movements and processes the TV image, is also compact and easy to carry. The calibration is automatic and completed within 1 min with a high degree of accuracy. By showing the tennis player's line of vision as an example, we were able to obtain good results with application in broadcasting programmes.
