In many previous studies on visual perception, the works on peripheral vision, especially that of concerning the space perception or figure recognition by indirect vision are not so many. The Author introduce a concept named "Perspective Vision", which is a perceptual two dimensional limited expansion. In the Perspective Vision, a polar coordinates system is adopted, where the point of fixation as the origin, and a objective distal point is localized to a certain distance from the origin. In this first report, one dimensional projection scale, on a line which pass through the point of fixation, is constructed by means of psychometric methods in conditions of dark room, monocular and fixed eye. The principal results are shown in Fig. (8) and Eq. (10), where the unit which reprsents the perceived perspective distance in Perspective Vision is named dil, and the magnitude of the dil against the point of fixation is shown as a function of physical peripheral angle. As for the charactor of the scale, Fig. (8) shows a considerable dilatation with the central vision as compared with the equidistant projection or general plane perspective. This charactor is represented by dilatancy ratio as shown in Fig. (10). Further, an approximate graphical solution about the scale is shown in Fig. (12) and Eq. (11)
