Electronic displays pose large human-engineering possibilities and, at the same time, new problems. One special aspect is the rotation of the display reference system. The human operator is unable to compensate for rotation. This is why tracking errors increase considerably at 90 and 270° rotation angles. Related experiments are described in detail. A new "action display" indicating the stick signal to the control system compensates completely for the rotation effect.
