Claims (10)

A method of providing adaptive physical indicators to a user of a personal care device , comprising:
determining a current orientation or position of the personal care device with a controller and one or more sensors of the personal care device ;
determining, by a controller of the personal care device , the deviation of the personal care device from a target orientation or the proximity of the personal care device to a target location ;
determining, with a controller of the personal care device , a desired correction of orientation or position ;
providing a user with a physical indicator using a sensory feedback module of the personal care device , the physical indicator providing a physical shift in the personal care device representing the desired correction; A method , comprising: 2. The method of claim 1, wherein the current orientation or position is determined using a camera, an inertial motion unit, an inclinometer, or a proximity sensor. 2. The method of claim 1, wherein the desired correction is made to enable feedback smoothing. 2. The method of claim 1, wherein the physical indicator has variable timing or magnitude. 2. The method of claim 1, wherein the physical indicator is applied in a proportional-integral-derivative scheme. A controller for providing adaptive physical indicators to a user of a personal care device, comprising:
determining the current orientation or position of the personal care device;
determining the deviation of the personal care device from a target orientation or the proximity of the personal care device to a target position;
determining the desired correction of orientation or position; and
A controller configured with a sensory feedback module to provide a physical indicator, said physical indicator providing a physical shift in said personal care device representative of said desired correction. An oral care system for providing adaptive physical indicators to a user of an oral care device, comprising:
an oral care device;
a sensor module that detects the position and angle of the brush head of the oral care device in the user's oral cavity;
a memory module configured to store data associated with brushing positions;
a sensory feedback module of the oral care device that provides a physical indicator;
An oral care system comprising a controller according to claim 6 . 8. The system of claim 7 , wherein the sensory feedback module relies on inertial steering to provide the physical feedback. 8. The system of claim 7 , wherein the inertial steering is provided by one or more control moment gyroscopes. 8. The system of claim 7 , wherein the sensory feedback module relies on one or more off-center masses to provide the physical feedback.
