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:

Compass Headband

While working with tactile displays I continued to consider what types of senses I could send to my body. Thinking about birds and my own lack of city sense I picked compass heading. I believe the less processing you need to do to understand consciously the sensations you feel, the more rapidly it will become background knowledge so the most direct analog to compass sense would be to vibrate my head north. Since my head has a full 360 degrees. I used the HMC6343, an arduino, 14 pager motors and a decoder/driver circuit I devised to run it.

Here are some pictures of the construction and the final headband:

Here’s the code used to communicate between the decoder and the compass: compassaccess.pde

With Punch!

With Punch is a festival which focuses on celebrating life in is its wonderful beauty and promoting real, genuine connections between strangers over free pie and punch. We hold With Punch annually for free in public spaces in Ann Arbor. Watching people walk right by each other I thought that if I could find something common between two they may form a connection. So I started out by bringing art supplies, musical instruments, juggling toys, punch, hot chocolate and pie I leave all these out and encourage strangers to interact with each other in anyway they wish. Starting in 2005 with a few supplies and a desire to create an environment I wanted to be a part of, WithPunch has grown into a music festival with cook-offs and crayon art competitions. An article at the Michigan Journal describes it as:

“Improvisation was everywhere throughout the event. However, things fell together one by one as Ghalib achieved his goal for the third time: eclectic entertainment and living life with vigor – sans alcohol or other drugs. … One thing is certain: Variety show was an understatement as a description for With Punch”

We’ve had 7 with punches so far. I can’t wait to hold the 8th. Here are some photographs from previous WithPunch events!
