A controlled environment for studying the three major factors of perceived image quality of mobile displays—motion, ambient lighting and surround—consists of (1) A robotic arm was programmed to simulate the motion caused by the hand shake, (2) A set of RGB LED lights was used to simulate illuminants such as fluorescent lamps or daylight, and (3) A rear‐projection screen was used as the surround to simulate indoor or in‐car scenarios. In addition, a face tracking device was used to record the variation in viewing direction. Psychophysical experiments were conducted to test the spatial‐velocity thresholds and just‐noticeable differences of various combinations of ambient and surround lighting conditions.
