A personal care device including at least one sensor () configured to obtain sensor data including information about a user; a controller () having a feature extraction module () and a classifier (), the feature extraction module configured to extract one or more features from the obtained sensor data, the classifier configured to determine a status of a user based on the extracted one or more features; and a personal care device () configured to provide a personal care function and receive one or more control signals to adjust the personal care function based on a determined status of at least a portion of the user's body.

Methods and systems for adjusting behavior of personal care device based on status of oral cavity

A method () for localizing an oral cleaning device within a user's mouth. The method includes the steps of: (i) providing () an oral cleaning device () with a motion identifier (); (ii) estimating (), 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 () information from the motion identifier regarding a completed transition to a second state within the user's mouth; (iv) comparing () 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 (), using a probabilistic graphical model comprising the first location probability and the transition probability, a probability of the location of the second state.

Methods and systems for oral cleaning device localization

A method () for localizing an oral cleaning device within a user's mouth. The method includes the steps of: (i) determining (), based on sensor information received from a motion identifier (), a first location of the oral cleaning device within the user's mouth; (ii) measuring (), using sensor information received from the motion identifier, an amount of time elapsing between a start and a stop of a movement of the oral cleaning device within the user's mouth at the first location; (iii) calculating (), using Fitt's law and the measured elapsed amount of time, the number of teeth the oral cleaning device was displaced during the elapsed amount of time; and (iv) determining (), based on the first location and the number of teeth the oral cleaning device was displaced during the elapsed amount of time, which of the user's teeth were included in the displacement.
