This is great. Imagine being able to touchscreen-enable any surface. You could touch your fridge & order more beer. Touch your couch arm & change a channel. Read and order from a menu projected on your table, with multiple people being able to order at the same time.
This is similar to the technology used in Microsoft Surface, the new tabletop computer. The difference? This one will cost you around $75 in wiiremotes and IR LEDs.
By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays
