Abstract
An on-body sensing system (30) comprises a plurality of skin interface elements for coupling electrical signals to and from the body. The system is adapted to derive an indication of a position of at least one positionable interface unit (32) based on transmission of signals between the positionable unit and a set of spatially separated reference units (34), the reference units being positioned at a set of known locations on the body. Transmitted signals are sensed at multiple pairs (52) of electrodes on each reference unit and signal characteristics derived for each pair, and based on this a direction of arrival of the signal determined. By collating all of the measured arrival angles, and by reference to a reference dataset containing information indicative of known signal arrival angles when signals are transmitted internally between the reference units themselves, an indication of position of the positionable unit is derived.
