Video in question

I am a student who is completing an assignment. I would like to ask a master. I made a video interactive project. The first group drew the outline of the object, and the second group drew the colorful square pattern in the center of the object. The third group depicts a pattern of colorful circles that appear expanded and colored when the camera captures a moving object. But now I want to make a modification. When the moving object appears above, the picture will appear square. When the moving object appears below, the picture will appear colorful circle to increase the sense of interactivity. What is the effect? What should I do? Can anyone give me some advice?
Thank you and best wishes
