Using the human body as a computer display of some sort is not a new thing (as there was always someone in elementary class that would jump in from of the projector on film day and shout “look – my tummy is a TV!”), but current work in this area is fascinating. A new article circulating today (I believe Dr. Peggy Semmingson was the first one I saw posting it) talks about an incredibly thin organic display being applied directly to our skin. The initial idea would be to measure and display various aspects of your health. Maybe someday it would display your emotional state and even communications. While privacy will need to be addressed (you don’t want a display of your feelings or heart rate on your should for all to see at all times, right?), still an interesting idea. I’m also a fan of the idea of the Cicret display band in the video above (which I believe Justin Dellinger brought to my attention). It just projects your cellphone display on your arm, and then tracks where you touch. It probably can’t give you the same health information as the skin display, so both could work together.
