Embodiment

[0014] Embodiment: the structure of the present invention is as figure 1 As shown, it is composed of a display 1, a microprocessor 2, a controller 3 and a data line 4. The display 1, the microprocessor 2 and the controller 3 are connected through the data line 4. The display 1 can be hung on the wall, and the microprocessor The program software is stored in the device 2, the circle pattern and the circle diameter can be displayed by the display 1, and the size of the circle can be adjusted by the controller 3.

[0015] The display 1 is a flat liquid crystal display.

[0016] The controller 3 is a special controller matched with the microprocessor 2, through which the size of the circle displayed on the display 1 can be adjusted.

[0017] The method for observing with the above-mentioned optical visual effect observation device is:

[0018] (1) Hang the monitor on the wall, and connect the monitor, the microprocessor and the controller with a data cable.

[0019] (2) The obs...

Abstract

The invention relates to an Ebbinghaus visual illusion demonstration device, which consists of a display, a microprocessor, a controller and data wires, wherein the display, the microprocessor and the controller are connected together by the data wires, the display can be hung on the wall, the microprocessor stores program software, numerical values of circle patterns and circle diameters can be displayed by the display, and the controller can adjust the size of a circle. When in use, the demonstration device is operated by two methods: method one: circles of circumferential circle groups are not changed, but center circles are changed until two center circles seem to have the same size; and method two: the center circles are not changed, but the circles of the circumferential circle groups are changed until the two center circles seem to have the same size.

Description

1. Technical field [0001] The invention relates to a demonstration device and a demonstration method for demonstrating optical visual effects, belonging to the technical field of experimental demonstration devices. 2. Background technology [0002] British vision scientist Al Seckel (Al Seckel) reported an Ibinghaus optical illusion in his book "The Art Of Optical Illusions". The phenomenon is two circles of the same size, one circle is evenly surrounded by a circle larger than it, and the other circle is evenly surrounded by a circle smaller than it, when the observer looks at it, he will feel the big circle The circle around is smaller than the circle around. The above-mentioned research results are very useful in demonstration experiments for college and middle school students, or in science popularization work in popular science publicity and education departments. However, the above results are only qualitative observations. On the one hand, the above results can only...
