I came across this the other day and got really excited. The portable projection computer is here! Pranav Mistry of MIT has created a wearable interface that allows wearers to access the internet as well as apps or runnable programs via the use of natural hand motion. Though the project is still in it's early stages, the prototype is essentially a combination of a camera, a portable projector and a mirror that is hung around the neck of the user. The user projects images onto any surface (if no surface is present, a hand will do). The hand motion is captured via the camera which picks up on the color caps that are secured to the tops of the fingers, although it is pointed out that nail polish may work just as well to differentiate fingers. In order for the whole set up to work, however, a cell phone is necessary. The cell phone acts as the processor for the system. Here are some links for the TED website:
