"Something we often do, is to spend great resources to achieve
certain capabilities." The opening words of this podcast are very
much the focus: We don't have to spend spend spend; sometimes the solution
is right at hand.
He shows in the podcast, two videos of his research, using the high
performance infra-red camera each Wii-mote actually possesses.
First, he demonstrates how a wii-mote, can be set up on a desk or ceiling
mounted, and pointed at an ordinary whiteboard. With an infra-red pen,
the ordinary board becomes an interactive whiteboard - at less than
5% of the cost of buying the equipment.
Because the camera can track multiple infra-red LEDs, the exact same
approach is used to create a multi-touch surface, for any application.
The second video shows how to use the Wii-mote for very cheap stereoscopy,
using infra-red LED wired safety glasses for eye tracking.
