Abstract
An electric toothbrushing device is disclosed, the device comprising vibration means for producing vibration of a toothbrush head and a controller for controlling the vibration means. The device also comprises a motion sensor for sensing motion of the toothbrushing device to produce motion data, and a signal analysis unit for analysing the motion data to produce a feedback signal. The controller is arranged to adjust the vibration produced by the vibration means in dependence on the feedback signal. Such a configuration can be used to improve the feedback provided to the user and/or help to correct deficiencies in the user's brushing technique.
