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.

Swift MoCap Sequence Retrieval
A better way has been developed for premade MoCap summoning. A method that uses general limb movements to call up the closest matching MoCap file.

MoCap for Movement Analysis
Promising work by QuinteQ on real-time motion capture without excessive hardware, holds promise for MoCap use in public VR.

Large Image Display: Simone: Mocap Animation Differences
In Lessons from Simone: MoCap Filter , it was discussed how Simone whilst yes she was controlled by Victor?s body movements in a MoCap system, never quite copied those movements perfectly. Whereas Viktor's movements are not always feminine, Simone moves with a permanent feminine grace.

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?

Lessons from Simone: MoCap Filter
Simone is a seminal virtual reality film, and there are several aspects of both the technology of VR and the social impact, which the film carries off very well, and which deserve to stand on their own merits. The MoCap filter the film alludes to, is one such aspect.

Interfaces > DesIRe
DesIRe is a gesture recognition system designed to aid virtual reality systems interfaces. It works via a variant on MoCap: The user dons a pair of datagloves embedded with illuminated LEDs.
