Interactive Sound Installation using a MPU-6050 (Accelerometer+Gyro)

Hello,
I'm working on an interactive sound installation based on a patch in Max/Msp; the sounds change according to the position of the mouse on the screen (I' m using the 'mousestate' object in Max) and I would like to replace the mouse with a sensor or a group of them. Ideally, I would like to have a sensor that works as a position detector; thus, I tried with a MPU 60-50 accelerometer and gyroscope, hoping that, when embedded in an object that one can hold, it can simulate the movement of the mouse following the movement of the person in the room. I came to the conclusion that this sensor can' t help me so I was looking for some advice on how to solve this situation.
I hope that everything is clear,
Cheers

Locating a moving object in a room comes up several times a week on this forum.

The answer is always the same and generally expensive: cameras plus image processing, Pozyx, your ingenuity.
