Magnetic MoCap

Magnetic motion capture does not use cameras. Instead, a network of receiver units is placed across all of the body parts of the user. These receiver units (and the user) are then surrounded by three electromagnetic coils, spaced equally around them. Each of the coils initiates an electromagnetic field, and the receiver units detect the relative intensity of the voltage from each.

An advantage of this system is that unlike most camera less motion capture systems, it is self-correcting. Errors do not compound over time. The disadvantages are of course standing inside an intense electromagnetic field, and the risk to health for both the user and the computer system.

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.

Magnetic Resonance Sensor in a Sugar Cube of Space
The debut of a new type of magnetic resonance sensor for brainwaves and electrical activity - which changes the game totally for both fMRI and MEG. For the first time ever, portable, low-cost versions of both are actually a possibility.

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?

Extra Sensory Perceptions: Sensing Magnetic Fields
The first known, successful implant of an extra sensory perception to detect magnetic fields the person with the new sense was near, occurred in 2005, when a small piece of neodymium, which is a rare earth metal, that forms a permanent magnet, was coated in a thin layer of silicon, and implanted into an emergency medical technician's finger.

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.
