This is a rather amazing piece of interactive technology. It’s still in the testing phase and was only recently announced at the TED conference, but it’s just amazing. It’s made from a simple camera, projector and a mirror on a unit you hang around your neck like a tie. This communicates with your mobile phone to form an interactive display which can be projected onto any surface and manipulated with coloured fingertips. This whole thing currently costs only USD $350 in it’s current configuration and further recduction in price and size may occour in the future. Many different uses and concepts have been imagined including a product rating system for the supermarket and a live plane scedule projected onto your flight ticket. A video which thouroghly explains this is below. The official website can be found here.
