«The technical process is as follows. In order to draw I wear a special helmet which is equipped with two infra-red sensors, which are in turn linked to two small video cameras. Via the reflexes of the retina the infra-red sensors follow the movements of my left and right eyes simultaneously and this input is recorded separately by the video cameras. These recordings can then be digitalized, for each point on which the eye rests for at least a hundredth of a second can be located in terms of coordinates on the X and Y axes. These coordinates can then be evaluated by a computer – in my case, by all points being plotted in terms of the temporal sequence in which they arose and then connected by an unbroken line, whereby the left and right eyes are treated separately.» Jochem Hendricks (source: Jochem Hendricks, Augenzeichnungen, Vexer Verlag St. Gallen and author, 1993; publ. on the occasion of the exposition »Zeichnung« in the Kunsthalle St. Gallen, 1993.)
