Human rig animations with Blender's motion tracking

Heya!

So the title says it. I’m making a FPS game with CryEngine, Blender and Gimp. I don’t have all these fancy “suits” to make human animations (or money to buy them…), so I thought would it be possible to (for example) tape red papers all around your body (to places where you have bones in your human rig) and record it and use Blender’s motion tracking -feature to “apply” it as an animation to the rig? I’ve heard that Blender’s motion tracking is quite efficient.

Thanks in advance!
