Tracking X, Y, Z axis within a small area?

Other Hardware Sensors

Hi There,
I am new to this forum and not an experience Arduino maker.
My project requires placing a sensor (3d accelerometer) to measure the position of a tennis racket in a simulator environment (similar to Kinnect or Wii).

Qustion:
A. which sensors do I need so I can program the Arduino to plot the position in 3D (using some sort of interface)
B. Which Arduino board should I use
C. Can I get the position accurate? (5-10 mm gaps?)
D. Any of-the-shelf program that I could use to visualize the movement on a PC screen?

Apologies if this topic has been discussed before, I could not find any.

Thanks is advance! :wink:

This is actually a very difficult task -- to a beginner I would suggest to pick another project.

You can use an accelerometer to roughly estimate changes in position and velocity of an object by the double integration technique, but you cannot determine the actual position. Read more here: http://www.chrobotics.com/library/accel-position-velocity
