Powerful Sensory Illusions with Everyday Objects
In my 3-day cognitive design workshop I ask participants to do a few short experiments using everyday objects (ping-pong balls, radios, chairs, etc.) designed to cause vivid perceptual illusions. During the debrief we talk about what the experiments reveal about how minds work and the implications for sensorial design.
A former participant sent me a note yesterday describing a recent story in the Boston Globe on Hack Your Brain: How to hallucinate with ping-pong balls and a radio.
The brief article covers five good experiments with one of my favorites illustrated below.

Try one of the experiments and let me know what you think it tells us about designing for how minds really work.
