Ebbinghaus visual illusion demonstration device and demonstration methods

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...

Problems solved by technology

But the above results are only qualitative observations. On the one hand, when the size of the circle is fixed, the above results can be observed when the difference between the large circle and the small circle cannot be given. On the other hand, when the size of the large circle and the small circle is constant, it cannot be given Find the gap between the real circle size and the observer's observation result

So far, there is no specialized equipment and method for observing
