Actually, depth perception is quite easy to do on the Wii. The wiimote's IR camera can track up to four points, so adding two more LEDs to your head tracking cap can provide enough data to distinguish between a turned head and one which moves closer to the screen.

Even with two on either side of the head if you turn your head so that they appear to be very close together it could be interpretted as you being very far away. Adding LEDs does help but then you can get into issues of setting standard arrangements etc..etc.. and with people making their own IR glasses for use it could get to be an issue in terms of programming as well. I think its far easier to just use two and honestly now that I think about it how often do you turn your head away from the screen in a game that would actually benefit from HT?

 Actually, I'm thinking of a third point placed high on the forehead, forming a triangle. If the two points at the base get closer together while the height of the triangle remains constant, the user is turning his head. If the proportion of the triangle stays constant, but the distance between all points changes, the user is moving closer or further away. It wouldn't detect the direction of a change in pitch or yaw, but it could correct for such a change so it doesn't misinterpret it as depth change.

 I don't see this arrangement being hard to implement. I'm pretty sure any game with head tracking implemented could use a two-point system or a three-point system, the three-point system is just less subject to confusion about depth.
