FIELD: hygiene; computer engineering.
SUBSTANCE: invention relates to methods and devices for controlling activity in oral hygiene. Tooth brushing control system includes a device for oral hygiene with a separate optical sensor for monitoring changes in the position of the oral hygiene device. Optical sensor can independently determine, in combination with the motion sensor data, the position and orientation of the oral hygiene device relative to the user's mouth. System can then determine the quality, quantity and location of brushing and provide feedback on the quality of brushing. This feedback provides motivation for users to improve their brushing habits, leading to reduction of plaque, dental caries and gingivitis.
EFFECT: oral hygiene system is provided with visual recognition to control dental cleaning compliance.
