| Popis: | Using a corneal reflection system consisting of an eye-mark recorder, the eye-movement, the time of fixation at a point and the frequency distribution were measured in the case where a man recognized shapes of three simple figures (a square, a triangle and a circle) and detected a different figure from many figures of the same shape which were moving at the same speed (5, 10 and 15°/s). After inspecting three types of figures moving at three speeds and moving his eyes to the characteristic points, that is, the tops and the ridge lines of figures, he could recognize the shapes of the moving figures whose sizes were 2, 10 and 15°of visual angle. His useful visual field size was about 16°in visual angle from the center of TV monitor base on the fact that he could detect a different figure (a triangle), which was located at 4 or 8°, out of many figures of the same shape (a circle) moving at 5.10 and 15°/s. |
