There is provided a device for monitoring usage of a toothbrush. The device comprises a body part, a core part and a base part. The body part comprises at least one through hole extending between an upper surface and a lower surface thereof. The core part receives the body part on an upper surface thereof and comprises on the upper surface at least one elevated portion connected to at least one force sensor which is connected to a micro-controller and which is connected to a Bluetooth transmitter. The base part for receives the core part on an upper surface thereof. A toothbrush inserted in the hole rests on the elevated portion, and a signal indicative of non-usage of the toothbrush is transmitted to the Bluetooth transmitter.

Provided are a toothbrush module, a toothbrush attachment, a brushing assistance system, a brushing evaluation system, a brushing assistance device, and a brushing assistance program that ease obtainment of a brushing action of a user even during brushing. A toothbrush attachment (2) includes: a sensor unit (21) that detects a predetermined physical quantity; a wireless transmission unit (22) that transmits a radio signal indicating the physical quantity detected by the sensor unit (21); a housing unit (201) that houses the sensor unit (21) and the wireless transmission unit (22); and a coupling mechanism (202) that removably attaches the housing unit (201) to a toothbrush (4). A wireless terminal device (3) includes a wireless receiver (31) that receives a radio signal and obtains the physical quantity, a music output unit (354) that outputs an image or sound so as to support brushing by a user with the toothbrush (4) based on the physical quantity, a figure display control unit (363), and a notification unit (373).

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

A system is providing that includes processing circuitry configured to receive information of a specific sensed condition of a body part of a user detected by the at least one sensor of a device during a session, receive information of a tracked location of the device from a location tracker during the session, associate a specific time when the specific sensed condition is detected with a location of the device in space at the specific time, and determine a location on the body part in a three-dimensional virtual environment where the specific sensed condition occurs based on the associated specific time and location of the device.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include an outer casing having an outer surface and a connection element that is configured to mate with a connection element on a handle of the powered oral care implement to couple the outer casing to the handle. The tracking attachment may further include a plurality of visual markers protruding from the outer surface of the outer casing.

Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis.

In some embodiments, usage of a personal care device in compliance with a recommended use is improved. A usage monitor computing device may detect and store records of use of the personal care device. The usage monitor computing device may transmit the records of use to a monitoring server device via a network. The usage monitor computing device may determine whether the records of use indicate that the personal care device has been used as directed by the recommendations, and if so, may determine whether one or more rewards for use should be provided to the user. The usage monitor computing device may receive notifications of the rewards, and may present notifications of the rewards to the user.

An oral-care system includes an oral-care device having a treatment head, a position-determination unit for determining position information of the treatment head in relation to a user's treatment area at a plurality of time instances during a treatment session, a sensor unit for determining treatment-parameter values of at least one treatment parameter at the plurality of time instances, a processor unit for processing the determined position information and the determined treatment parameter values to generate at least position-resolved treatment data, a memory unit for storing at least the position-resolved treatment data, and a control unit for triggering an action of the personal-hygiene system based at least on a current position information and on the stored position-resolved treatment data.

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

A method for estimating a pose of an oral hygiene device including a pattern and a plurality of groups of visual markers relative to a location includes (i) receiving image data reproducible as an image of at least a portion of the oral hygiene device; (ii) analyzing the image data to identify a region of interest within the image; (iii) identifying, using at least one of the one or more processors, all candidate visual markers within the region of interest; (iv) obtaining a first proposed three-dimensional pose of the oral hygiene device; (v) validating the first proposed three-dimensional pose of the oral hygiene device; and (vi) obtaining a second proposed three-dimensional pose of the oral hygiene device based on the validated first proposed three-dimensional pose.
