Input Options

I've been researching different motion sensing options for the project. The first option that came to mind was the wii remote.

I looked at Johnny Lee's work using the wiimote to finger movements and head tracking.

Many of his projects used C# and other programs.

This is a forum website I came across with lots of info on connecting the wiimote to connect to the pc as well as programs to use wiimote input.

This is a Japanese website that has written a program to use the wiimote and the PS3 six axis controller with a pc

Here is another resource in wiki form.

While at Fry's electronics looking for bluetooth dongle's and wiimote accessories I came across this mouse which is like the wiimote in the sense that it has motion tracking capabilities. This would make connecting to the pc a lot easier however it is also expensive and probably has less creative development from hackers than the wiimote right now.
