I caught this video. I don’t really have cause to use a interactive white board. Or track eye movement. But it has has the potential to track anything. And by doing so control anything. Music and video performance came to my mind. A less than $40 dollar piece of hardware connected to a PC via ubiquitous blue tooth opens a myriad of possibilities. It is a wonderful when a mass produced(read as cheap) hardware can be co-oped into a whole bunch of unintended applications.
