Abstract
A wearable device to be worn on a body part includes deformation sensors and a controller. The controller instructs the deformation sensors to measure deformation forces. The controller determines a position of the body part based on the measured deformation forces and a transfer function that maps deformation forces to positions of a same or corresponding body part. The transfer function is generated based on measurements from calibration and deformation sensors to sense corresponding positions of the body part and deformation forces. A calibration sensor may include a magnetic field generator and a magnetic flux sensor. The wearable device may be a glove and the body part may be a hand.
