First poster here, so please excuse lingo mistakes…
We are currently involved in a light tagging project using a Wii controller. You can read more about it here http://mysite.saeamsterdam.com/~500440, if you want. It works great ‘in the lab’, but we found that having the Wii controller read the IR data in a live situation is prone to interference, and also limits the user a lot in their movements. Now we’re looking for a different way of reading out where the controller is held on an xy grid. We thought of different techniques (camera tracking, high freq range sensors), but they all come with drawbacks (interference/cpu intensive and a whole new technical ballpark, respectively). We can pretty much attach or place anything to or in our controller. Somehow I feel there should be an easier way for this, that we’re missing, because we don’t know how to look for it (if that makes any sense)…
I know this is not directly Arduino related, but I thought there might be some sages out there that wouldn’t mind shedding their light on this.
If you have any ideas or further questions, please post!
