Wearable magnetic field sensing for finger tracking

Obtaining a signal useful for continuous pointing input is still an open problem for wearables. While magnetic field sensing is one promising approach, there are significant limitations. Our key contribution in this work is a simulation of a system that tracks a magnet in 3D while also accounting for the ambient magnetic field. The simulated sensor data is processed and the position and rotation is determined by using magnetic field equations, a particle filter and a kinematic model of the hand.
