Idea for Positional Tracking possibly.
So I was just watching some videos about the Oculus hd prototype at E3 and it hit me that wouldn't it be possible to have positional tracking by just using accelerometers? I don't have a whole lot of experience with accelerometers and or any tracking devices really, never developed with them or even made a simple circuit with one. However it seems that it would not be too difficult to get a fairly accurate positional tracking system working with accelerometers.
Here is how I imagined it.
1. You put on the rift and before starting the game you sit or stand in whatever default position you want to be your default to be.
2. Start game, the game will start and create a positional map (Not sure what to call it).
(Calibration would be big for this part)
3.As soon as you make any movements, the accelerometer or accelerometers detect acceleration in the X,Y,Z axis and save the data as your movement. Now the system or game can calculate where you started based off the acceleration and direction data. So now by tracking all movements in any direction, the system knows where your default position is in relation to any and all movements.
Obviously the system would need to have a low latency and high acceleration data gather rate. If you had a 100hz accelerometer and you moved at 1ft a second, it could track individual movements down to .12 inches. That would seem more then enough for the Oculus Rift. Unless I have no idea what I am talking about, lol.
So with accelerometers for the X,Y,Z axis, you now have the ability to move anywhere and the system can track all movements to within some degree(Have no idea really). So does this sound at all feasible? Maybe someone with experience could tell me if this could work or not. I would test it myself, but I just don't have the time.
