A researcher takes Nintendo Wii remote and demonstrates at Ted Talks how this particular technology can be used for education. Anthony took his idea and made it come to fruition. He made an interface out of a simple IR pen and a Wiimote that is capable of turning any data projector into an interactive whiteboard irrespective of the surface that is used. Anthony strongly claims that this easy setup costs less than $100 installed tied with the free Smoothboard software has the potential to be one of the most exciting innovations for some time.
What he has done is taken ~$50 worth of hardware saving thousands to allow about 80% of the capability with less than 2% of the total cost to have a true interactive whiteboard.
