Patent ID: 10517532

Abstract:
While a toothbrush is moving in an X-/Y-plane relative to teeth of a person, a camera of a tablet PC or mobile phone captures an image area containing one or both pupils, the nose, eyebrows, eye hole, lips, ears, cheeks and/or chin of the person and the moving toothbrush. Rotational movements or acceleration of the toothbrush may be sensed by a sensor disposed in the toothbrush to generate sensor data. The sensor data is wirelessly transmitted from the toothbrush to the mobile phone or tablet PC, and the sensor data is processed. The resulting processed data is compared with movement pattern data or movement characteristics data stored in a database to generate comparison data, and correction parameters for adapting the movement of the toothbrush are determined based on the comparison data. Correction information is generated based on the correction parameters and displayed on a screen of the mobile phone or tablet PC.
