Abstract
A wearable device to be worn on a body part includes a magnetic field generator, a magnetic field sensor, and a controller. The controller instructs the magnetic field generator to generate a magnetic field, instructs magnetic field sensor to measure a sensor signal, and to determine a position of the body part based on the measured sensor signal. The magnetic field sensor can include multiple sensor elements with known or solved positions relative to one another. The wearable device can be a glove. The controller may determine a bend angle of a finger or an angle between two fingers.
