Abstract
A wearable device (such as a glove or other control adapted to be worn on a portion of a body) includes multiple magnetic field generators at various locations on the wearable device and a magnetic flux sensor at a predetermined position relative to the wearable device. A position determines spatial positions of locations of the wearable device based on magnetic fields generated by various magnetic field generators and detected by the magnetic flux sensor. In some embodiments, the magnetic field generators have known positions relative to each other. Additionally, each magnetic field generator may generate a magnetic field in response to an input signal having a particular attribute, allowing the magnetic flux sensor to identify magnetic fields generated by different magnetic field generators.
