Method and device for pose tracking using vector magnetometers
First Claim
1. A system for allowing a user to interact with a computer in at least 5 degrees of freedom, the system comprising:
- a computing device;
a visual screen associated with and controlled by the computing device;
two or more vector magnetometers associated with the computing device;
a user-borne device comprising one or more permanent magnets, wherein manipulation of the user-borne device by a user is tracked by the computing device via measurement of a magnetic field associated with the one or more permanent magnets by the two or more vector magnetometers that are stationary with respect to the computing device to generate pose information associated with the user-borne device, the pose information including a position and orientation of the user-borne device, wherein each vector magnetometer detects a field associated with all of the one or more permanent magnets.

Abstract
In accordance with various embodiments of the invention, a user-borne computer input device is disclosed including a 5D or greater “mouse” or other tool or object containing or consisting of one or more permanent magnetic presenting permanent magnetic dipoles. The position and orientation of the device are determined by magnetic field strength measurements derived from at least two vector-magnetometers fixed in a reference frame connected to the computing device. The system allows a user to interact with the computing device in at least 5 dimensions by manipulating the position and orientation of the device within a measurement volume, which may be a few cubic meters.
