Abstract
A wearable sensor system is disclosed that provides a measurable magnetic field that changes horizontally within the range of motion of human limbs. The wearable sensor system includes a magnetic sensing device, and one or more magnet devices that provide the measurable magnetic field with a strength exceeding the Earth's magnetic field. To this end, the magnetic sensing system provides a “personal” magnetic field about a user, with that magnetic field traveling with the user and overpowering adjacent interfering fields. The wearable sensor system may include a sensor arrangement that measures a strength of the personal magnetic field and field direction to perform horizontal localization, and may send a representation of a same to a remote computing device to cause an action to occur. Some such actions include output of pre-recorded or synthesized musical notes, for example.
