More Information
Summary:The dental position tracking system includes a toothbrush (30) which has a system (20) for determining the orientation of the toothbrush in the mouth of a user relative to the earth, based on measured stored information. Information is stored in the toothbrush concerning target ranges of expected measured toothbrush orientations for each of a plurality of dental zones (22). A processor (24) compares the measured toothbrush orientation information with the target orientation ranges, following conversion of both the target orientation information and the measured toothbrush orientation information to the same coordinate system. The processor then determines which if any of the target ranges matches, within a selected tolerance thereof, with the toothbrush orientation information. Any difference between the target range and the measured toothbrush orientation information is then used to partially adjust the target information range, in order to compensate for a change of position of the user' s head.
