wiimote and sensor bar

[masaki]

hey guys,
so my lab wants to start using the wiimote for different experiments. for one of the experiments we want to use the wiimote for pointing tasks while in VR with tracking (head and body). so a few questions: we haven't purchased the sensor bar yet. The sensor bar that comes with the wii plugs into the wii for power, so is there a wired sensor bar that plugs into a regular socket for power or would we have to jerry rig our own power source (which should be pretty simple)? i've found a couple wireless sensor bars that run on battery also, would this be the best solution? Also, with the sensor bar, what is the angular range the wiimote will be able to accurately give pointing responses? e.g. if the sensor bar is directly in front of the subject, does that mean the angular range would be at most 180 degrees in front? if that is the case is using multiple sensor bars an option if we want a full 360 degree range? thanks in advance.

It shouldn't be too difficult to make your own sensor bar. You just need to make sure you use the correct LEDs. Here are a few sites that show how to make your own.

I would prefer a wired sensor bar, as opposed to a battery powered one, just because it ensures the LED stays nice and bright.

The sensor on the wiimote has around a 45 degree fov for detecting the IR dots. Adding multiple sensor bars won't really help, because there is no easy way to identify which bar you are point towards. If you need full 360 degree pointing then I would recommend using an InertiaCube, if you have one available.
