TED 2008, the annual Technology, Entertainment and Design Conference, was held this March in Monterey California. Among the most exciting talks given was by Johnny Lee, who displayed two incredible uses of the Wiimote controller from the Nintendo Wii. Using the infrared camera at the front of the controller, a projector and an infrared pointer pen, he has made a virtual whiteboard that can be manipulated at more than one place at a time.
This interactive whiteboard is a fraction of the cost of traditional ones. Using sunglasses that emit two infrared dots that show where the glasses are looking Lee also used the Wiimote to make a flat TV screen look truly 3D to the wearer of the sunglasses. Watch and be amazed.
