I've been contemplating a project and I want some opinions on whether the Wii equipment can be used to pull it off.

My idea is to team head tracking with the Wiimote with display glasses from myvu.com to create an immersive 3D environment, preferably for first-person shooters.  The idea is to be able to move the camera by head position independent of the direction the avatar is actually facing.  A second Wiimote would be used to move the targeting reticle around in your field of view, but would require 360 degree rotation, which might require the construction of a kind of "IR cage" with IR LEDs mounted all around the room.

To control movement, I'm thinking a Wii Balance Board (also a bluetooth device), which measures the users center of gravity.  Lean forward and the avatar would move forward, left and right would control strafing movement, and even crouching could be accomplished since it alters your center of gravity, which the balance board could detect.  Mount the board to a turntable to track 360 degree rotation and you have full 3D immersion.

So, does this seem feasible with the given equipment?

I think it would be a great project.  I would not worry about the full cage, or the multiple wiimotes for turning in circles.  The difficulty I see there would be with coordinating the direction you are facing with the balance board and your center of gravity.  I would also think it would be difficult to turn in a circle on the balance board without it trying to move you around as well.

I think it would be enough to have the 6dof for your head and looking around, and then using a second wiimote for aiming and firing, with a nunchuck connected to it for changing the orientation of the body.  I would see the myvu as your screen.  Attached to the myvu would be the 3 ir leds needed for the 6dof.  By the computer you would have a wiimote to take care of tracking the leds on the myvu.  The player would then be holding a wiimote with nunchuck for aiming, shooting, and the other assorted things needed when playing the game, and the nunchuck for body orientation (direction the body is facing).  The player would stand on the balance board and use it for the actual movement - lean forward to move forward, back to move backward, and to the side to strafe.

Not sure if the myvu would be good glasses though, because I believe the glasses would need to block out more of the world than the myvu - it will also be nice once the glasses can get a better resolution...
