Pattie Maes of the MIT Media Lab is working on projectable user interfaces:
It lets you walk up to any surface (including your hand) and interact with the projected interface. It responds to his gestures. If you hold your hands like you are taking a photo, the camera takes a photo, and then when you go back to the office, you can project all your photos and sort through them using natural gestures. She showed a projection of a phone keypad on her palm and dialed a number to make a call.
She shows a video of a guy looking at products in a supermarket. It projects a green, yellow, or red dot on a product, telling you whether or not it’s eco-friendly (or whatever criteria you set up). If you look at a book, it’ll project the Amazon rating on the book. Projecting a video of a news story on a blank rectangle on theĀ Wall Street Journal!
