Abstract: The present application relates to a system (10, 60) for treating a part of a body of a person to be treated. The system includes a treating device (20, 70) having a treating unit (22, 72) and a reference member (40, 80) adapted to be mountable to a person in fixed relationship to a part of the body. The treating device (20, 70) has a first motion identifier (28) configured to generate information indicative of the acceleration and/or angular orientation of the treating device (20, 70). The reference member (40, 80) has a second motion identifier (48) configured to generate information indicative of the acceleration and/or angular orientation of the reference member (40, 80). A controller (27, 47) is adapted to produce information indicative of the trajectory and/or orientation of the treating unit (22, 72) relative to the part of the body to be treated based on the information provided by the first and second motion identifiers (28, 48).

Abstract: A method (300) for localizing an oral cleaning device within a user's mouth. The method includes the steps of: (i) providing (310) an oral cleaning device (10) with a motion identifier (28); (ii) estimating (335), based on sensor information received from the motion identifier, a probability of a first location of the oral cleaning device within the user's mouth; (iii) receiving (340) information from the motion identifier regarding a completed transition to a second state within the user's mouth; (iv) comparing (350) the completed transition to a defined set of possible transitions between each of a plurality of possible states within the user's mouth to determine a transition probability; and (v) determining (350), using a probabilistic graphical model comprising the first location probability and the transition probability, a probability of the location of the second state.
