1. The Pursuit-Pursuing Illusion
Please use a large monitor to see this demonstration,
or view the image at a very short distance.
Start “slide show” and click once, then a small black dot will appear and start moving.
Please track it with your eyes.
Moving your pointing finger to pursue the dot will help your eye movement.
You will notice that yellow disks are seen to move with your eye movement.
This illusion is not seen when the luminance of the yellow disk is too low or too high.
Please try to find the best luminance condition for your monitor.
