Wearable electronics dont just have to go on your wrist or your face, it turns out: students in New York Universitys Interactive Telecommunications Program (ITP) have designed what they call the Smart Hoodie, a hooded sweatshirt with a GSM radio sewn in that can respond to different gestures. The creators show three of those gestures in their demonstration — touching the hood, touching a sleeve, and rolling up a sleeve — each of which send a different text message to a pre-programmed contact.
