DC Magnetic systems have very negative reactions to metal or magnetic fields in the environment. Often a stage can be built to lessen interference from metal in floors, but metal in walls, ceilings, structures, props and interference caused by electrical devices is another story. We've heard of companies resorting to setting up in a parking lot just to get away from metal. Setting up a DC magnetic system in an uncontrolled environment, such as at a trade show can be a harrowing experience. We receive a lot of interest in the Gypsy motion capture system from people who have DC magnetic systems they aren't using due to difficulties with metal in the environment.

In summary, DC magnetic motion-capture systems
have the following shortcomings:
