SOCR Project - SOCR Interactive Optical Illusions Project

Project Goals

Stare at the cross (+) in the center and you will see a series of events: One purple dot disappears; One purple dot turns green; Some/all purple dots disappear; Only the green spot remains, circling around the cross.

This project aims to design, implement and promote a set of diverse optical illusions using motion, color, shape, appearance, visual and perceptional cues, etc. The applets mush be lightweight, allow user interaction, convey interesting/unexpected visual illusions, and provide appropriate explanations for all of these visual perceptions. One example is the Pacman's illusion (right). Additional examples of such visuals are included below.

Adelson-Checker-Shadow

The Adelson-Checker-Shadow illusion is very interesting. The color/shade of square A is exactly the same gray shade of square B. You can see the evidence by clicking on the Show button to the right. Even after seeing the proof, your eyes may still keep deceiving you. SOCR AdelsonCheckershadow Fig1.jpg


Tables Illusion

Are these tabletops the same size? SOCR Illusion Table1 2.png


Alternative Illusion Projects

There are a number of alternative mind-illusion projects similar to the optical illusions that can be initiated.

Audio Illusions

One can use audio stimuli to convey an illusion or to capture data about sound/tone perception. Then one can investigate phenotypic effects (e.g., gender and age) on the brain processing/perception of audio signals. See Sound-Cloud.
