PSYCHOPHYSICAL ANALYSIS OF THE SENSATION OF REALITY INDUCED BY A VISUAL WIDE-FIELD DISPLAY

This report summarizes research on the psychological effects induced by certain parameters of visual wide-field display. These effects were studied by means of three different series of experiments. The first experiment series evaluated the subjectively induced tilt angle of the observer's coordinate axes when presented with a tilted stimulus display pattern. The second experiments were to determine the observer's eye and head movements for information acquisition when presented with a visual wide-field display. The third series of experiments was to determine, by means of a subjective 7-step evaluation scale, the viewing conditions under which the display induces a sensation of reality in the observer. From the results of these experiments it was concluded that a visual display with horizontal viewing angles ranging from 30 degree to 100 degree and vertical angles from 20 degree to80 degree produces psychological effects that give a sensation of reality.
