摘要

A method for contactless, helmet free measuring the viewing direction of eyes in the case of head - and eye movements, in which the eye with a pulsating or not - pulsating infrared light is illuminated by a containing a lens optical system is shown, of an image sensor (ccd - video camera) and the thus received image obtained in a subsequently, by means of a main processor configurable a view direction - processor for the determination of the viewing position by determining the coordinates of the eyeglasses or corneal reflections is further processed and is displayed on a monitor, whereby a digital gray scale image is generated, whose gray level distribution over all video lines, and each analyzed fifo bright to dark - - - - to bright and dark transitions searched for the ascertained positions of the transitions can be stored and the coordinates on at least one predetermined fixation point, to be calibrated, characterized in that the video image by integration over a time interval t_i engaged, then this image at the point in time of the image change for the purpose of detecting the next image on the ccd - sensor are stored and only after a time interval t_i + T_u for the digitalization and transmission in a further time interval of..
