Mechanical MoCap

Mechanical motion capture does not use cameras. Instead, a network of sensors is placed on all the body parts of the user. These sensors work by detecting the relative motion of each joint, and one sensor system is applied to every joint on the body. They function like a web, directing 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. They do have a major downside, however. Because of the need to accurately measure every joint, they tend to be built into a rigid framework which wraps to the user like an exoskeleton. This adds weight and a certain inelegance to the user?s movements.
