Problems solved by technology

But the above-mentioned result is the result of human observation on the one hand, it will produce different observation results due to the difference in the degree of concentration of the observer's gaze, the speed of the head moving back and forth, and the stability of the head and neck during the movement process; On the one hand, only relying on the forward and backward movement of the human head can only observe for a short time, and long-term observation will cause fatigue in the head, neck and even the whole body
So far, there is no dedicated equipment and method for observing and measuring

Embodiment

[0018] Embodiment: the structure of the present invention is as figure 1 , figure 2 and image 3 As shown, it is composed of a test car 1, a special track 2 for the test car to run, and a test board 3. A seat and a tester's head and neck positioning device are fixed on the test car 1, and the test car 1 is located on the special track 2; The board 3 is located at the other end of the special track and installed on another test vehicle 1. The height of the test board is adapted to the height of the tester; there are two concentric circles composed of the same pattern on the test board.

[0019] The head and neck positioning device is a height-adjustable deck-type positioning device. The positioning device is composed of a vertical shaft 4, a horizontal plate 5 and a vertical plate 6. The vertical shaft 4 is fixed on the test vehicle 1, and the horizontal plate 5 Installed on the vertical shaft 4 through the horizontal plate adjusting groove 7, and the vertical plate 6 is ins...

Abstract

The present invention is optical visual effect test apparatus and method. The test apparatus consists of test vehicles, test tracks and test board. One of the test vehicles has one chair and one testee head fixing device and is on the tracks; and the other test vehicle has one test board with 1-5 concentric patterns installed. During test, the testee with his head fixed stares at the pattern center and these two vehicles are made to move relatively, the square pattern will be seen to rotate counterclockwise or clockwise around the circle center in the rotation speed changing with the relative speed between the testee and the test board. The present invention may be used for demonstration of optical visual effect and for game.

Description

1. Technical field [0001] The invention relates to a test device and a test method for experimental demonstration of optical visual effects, belonging to the technical field of experimental demonstration devices. 2. Background technology [0002] A visual picture of a "rotating circle" was reported in "Visual Games (2)" written by British visual scientist Al Sekel, published by Hainan Publishing House in April 2004 and translated by Hong Fang. The picture is composed of two concentric circles composed of rhombus patterns. When you focus your eyes on the center of the concentric circles and move your head back and forth, you will find that the two concentric circles composed of rhombus patterns will rotate. This phenomenon was discovered in 1999 by Italian vision scientists B. Pina and G. Grystaff. The above research results are very useful for college and middle school students to do demonstration experiments, or to do science popularization work in science popularization a...
