Hi Bo-Erik, Thanks for your reply. Yes, I considered using the Wii but the downside is that since it relies on IR, you are constrained to the IR sensor being in line of sight with the emitter. For visual purposes where you have to look at a screen in front of you I can see this working but for ambisonics, being periphonic, I wanted to have the freedom of turning 360 degrees to explore the soundscape.
