Problems solved by technology

Because this technique is based on the orientation of the handheld personal care device relative to the world, movements associated with use of the device may not be distinguishable from non-use movements such as walking or turning the head
Thus, if accurate location data is desired, the user is forced to limit his / her movement while the user is operating the handheld personal care device

Abstract

A method for monitoring the position of an oral care device in the mouth of a user, the method comprising the steps of emitting energy towards the user's face, receiving reflected energy from the user's face corresponding to the emitted energy, and determining the position of an oral care device in the mouth of the user using the received reflected energy and facial characteristics information ofthe user which relates to one or more facial features of the user.

Description

technical field [0001] The present invention relates to a method and system for monitoring the position of an oral care device in a user's mouth. Background technique [0002] Determining positional information of the handheld personal care device and its components relative to the user's body enables monitoring and guidance in personal cleansing or grooming regimens such as tooth brushing and interdental cleaning, facial cleansing or shaving, and the like. For example, if the location of the head member of the personal care device is determined within the user's mouth, portions of a group of teeth, specific teeth, or gum portions may be identified so that the user may focus on these areas. [0003] To facilitate proper cleaning techniques, some devices contain one or more sensors to detect the position of the handheld personal care device during a usage session. Existing methods and devices use inertial measurement units, such as in electric toothbrushes, to detect the ori...
