Colorshifting Biofeedback Glasses – Representing Stress Responses Visually

DSC 0683

After hearing about the Iowa Gambling Task experiment in which subjects are given decks of cards and are asked to pick between them. Each choice either wins them money or loses them a certain amount depending on the value of the card. A healthy individual will begin picking the deck that offers him the highest running values after picking approximately 50 choices. But amazingly after 10 choices the individual’s galvanic skin response jumps. Here’s a Google Books link to the paper by Dr. Damásio: Insensitivity to future consequences following damage to human prefrontal cortex.

It seemed likely that by getting closer insight into our emotional states we could make better decisions. So I made these glasses that tinted your peripheral vision depending on your galvanic skin response. Using a simple voltage divider circuit, an arduino, RGB LED’s, safety glasses and diffusers I was able to make glasses that related information from my subconcious and displayed it to a sense that I was very aware of… vision. Here’s a video me and a friend Anand Atreya going through some GSR tests and the goggles in action:
