Context

Outside of basic images showing the Ebbinghaus illusion, our outcome was greatly influenced by a video demonstrating the illusion with moving circles. In it, the effect appears to be stronger when the central circle moves across the screen with expanding and contracting surrounding circles. Our product incorporates this idea and moves a series of Ebbinghaus circles across the screen, hopefully achieving the same magnified effect. To further unify the audio and visual components, we applied a space theme, with the circles as planets against a star field background.

In the illusion, the only difference between the two sets of circles are the sizes of the outer circles. The size of the inner circles remain the same. To emphasize that difference, we animated only variations of the sizes of the outer circles to show how our perceptions change because of relative size.
