Firstly, our original version, though it worked, had some problems. The compass module and 3D sound aren't as accurate as we would like. We spent a few hours working on the calibration of the compass module and we have it acceptably accurate, but the 3D sound could possibly be improved through more advanced use of HRTF. I will be looking into this over the coming days.
I have written a GUI tool (in Python) which allows us to place sounds around the listener by simply clicking on the GUI, select which sound is audible and cycle through them. It also automatically cycles through the sounds if you simply look at the current sound (that is, you look in the direction which the sound appears to be coming from) for five seconds.
The green dot represents the position of the listener (currently this is static, but when we have the Ubisense working, it should move around as the user walks around). The black line represents the direction the listener is facing and is driven by the digital compass.
The grey dots represent sounds previous to the current one (in the list of sounds), the blue dots sounds that are yet to come in the list and the red dot is the currently audible sound. Over the coming weeks, I intend to extend this program (and the FMOD audio daemon) to allow for multiple different sounds to be playing in different positions at once as well as allowing the Ubisense to drive the position of the listener.
Myself and Graham have been in contact with Dr. Lorcan Coyle from the UCD Complex & Adaptive Systems Lab in regards to using their Ubisense system and he has confirmed that it is ok for us to do so. Myself and Graham will be visiting him in UCD next wednesday (the 13th).
