Inertial MoCap

Inertial motion capture does not use cameras. Instead, tiny inertial sensors are placed on all the body parts of the user. This can either be done manually or by embedding them into a suit. The inertial sensors function like a web, each relaying its data, usually wirelessly, to a central computer system which builds up a map of changes in bodily position on a real-time basis.

Advantages of this system are of course the low footprint ? no need to set up a room especially. A downside however, is that the sensors due to their small size, tend to only be accurate to the nearest degree or so, and lacking any visual component to correct mistakes, errors compound over time.

Combining MoCap and Gesture Recognition
MoCap - Motion Capture - for all its impressive abilities, has definite limitations in terms of sensory fidelity, the expense and bulk of the rig. Gesture control is cheap and captures every little movement, but easily overwhelmed. Is a hybrid system possible?
