In another embodiment, the user terminal is a HUD (Head Up Display) device. This embodiment gives a specific example, referring to a front view of a HUD device shown in fig. 2 and a side view of a HUD device shown in fig. 3, showing a head-up display 1 and a base 2; among them, the base may be provided thereon with, for example, a switch button, a function button, etc., and the base may be internally provided with various function units such as a storage unit, a communication unit, a processing unit, and a power supply unit. After the condition that the user triggers the toothbrush is monitored, the user terminal activates a head-up display, and the head-up display can display corresponding contents according to the identity of the user or according to preset settings of the user, such as interactive games, animations and the like which guide the user to standardize actions when children brush teeth; when an adult brushes his/her teeth, the heads-up display may prompt information such as brushing regimen. In addition, the user terminal can provide functions of news feed, mail push and the like through the head-up display so as to be convenient for a user to check during tooth brushing, and the content displayed by the user terminal through the head-up display can be content of the terminal which is synchronous with a network or content pushed by built-in news software and the like.
In addition, in other embodiments, the user terminal may include a projection device or the like, or may be displayed by using HUD technology, but other projection carriers such as a mirror, a glass, a wall surface and the like may be used as the display terminal, so that the display terminal may not be separately provided.

The intelligent toothbrush can collect tooth brushing characteristic information of a user through the functional components and send the tooth brushing characteristic information to the user terminal through the wireless communication unit.
Referring to fig. 4, a flowchart of a tooth analysis method executed by a user terminal, that is, described by way of example from a user terminal, the user terminal being in communication with an intelligent toothbrush, includes the following steps:
and step S402, when the situation that the intelligent toothbrush is started by the user is monitored, identifying the identity information of the user.
And step S404, determining the tooth brushing specification corresponding to the identity information.

It should be noted that the brushing analysis method of the present invention is not limited by the specific sequence depicted in FIG. 4 and described below. It should be understood that in other embodiments, the order of some steps in the method may be interchanged according to actual needs, or some steps may be omitted or deleted. For example, there is no precedence relationship between step S402 and step S406, or between step S404 and step S406, and they are interchangeable in practical applications.
The embodiment further provides a mode that the user terminal acquires user data through the intelligent toothbrush, the intelligent toothbrush acquires all signals of the tooth brushing behavior of the user through an accelerator, a gyroscope, a magnetometer and the like, and can receive necessary data sent by the intelligent toothbrush according to preset conditions so as to save storage space.
The user terminal can also periodically transmit data acquired from the intelligent toothbrush and data generated by analysis of the user terminal, such as a tooth brushing analysis report and tooth brushing specifications corresponding to identity information, to the server, namely to the cloud, and store the data in a storage space corresponding to the user in the cloud. In one example, the user terminal is a personal device of a user such as a mobile phone and the like, and can store data and interact with each other; the user terminal can be provided with tooth brushing software, and data cloud transmission is carried out on the premise that the personal equipment is confirmed to be connected to the wireless network. In another example, the user terminal is a standalone terminal as shown in fig. 2; when each tooth brushing is completed, the independent terminal can synchronize data to the cloud terminal through the connected home wireless network. The data to be transmitted includes the individual ID of the user, the hardware ID information of the toothbrush, and the terminal information. The independent ID information of the user ensures that the data can be accurately imported into the cloud space of the corresponding user; the hardware ID information of the toothbrush can be used as reference data such as the frequency of brushhead replacement for a series of subsequent applications; the terminal information may be used as reference data for subsequent applications including user usage environment and the like. And if the cloud server detects that the user data is not synchronized for a long time, the cloud server can send a data synchronization prompt to the user terminal.
For step S402, the present embodiment provides the following four ways of identifying the identity information of the user:
the first method is as follows:
and determining the identity information of the user according to the brush handle number and/or the brush head number of the intelligent toothbrush.
When the intelligent toothbrush is in communication connection with the user terminal, the user terminal can determine the identity of the intelligent toothbrush, each intelligent toothbrush is provided with a unique identifier, and specifically, the brush holder number and the brush head number of the intelligent toothbrush are unique.
The smart toothbrush can be used as a device in the unit of home. Smart toothbrushes may comprise one or more handles; under the application that a plurality of people use one brush handle, family members change the brush head before brushing teeth, the identity of the members who use the brush head can be determined according to the matching information of the brush head and the brush handle, specifically, the brush handle number and/or the brush head number, and the brushing teeth data is recorded into the corresponding member database. In case there are multiple handles we can identify based on the brush head handle match information as well or just the handle number.
The second method comprises the following steps:
acquiring biological characteristics of a user through the intelligent toothbrush, and determining identity information of the user according to the biological characteristics; wherein the biometric characteristic comprises a fingerprint characteristic or an iris characteristic.
The intelligent toothbrush can be provided with a fingerprint acquisition area or an iris acquisition area and the like, and identity information of a user is determined based on biological identification modes such as fingerprint identification and iris identification.
The third method comprises the following steps:
and acquiring identity information input by a user through the intelligent toothbrush.
The intelligent toothbrush can be provided with a user identity input end, and a user can directly input own identity information on the intelligent toothbrush.
The method is as follows:
after the tooth brushing characteristic information of the user is extracted, comparing the tooth brushing characteristic information with a pre-stored characteristic template library to determine the identity information of the user corresponding to the tooth brushing characteristic information; the feature template library stores the corresponding relation between the identity information of the user and the tooth brushing feature template, and the tooth brushing feature template is generated based on the tooth brushing feature information of the user for multiple times. That is, the tooth brushing characteristic template is generated according to the tooth brushing habit of the user, and is different for different users.
In the fourth embodiment, the identification information for identifying the user in step S402 is not executed immediately, but the step S406 is preferentially executed, and the user is identified by matching the acquired tooth brushing characteristic information. Specifically, the user terminal identifies the tooth brushing actions of the user through quantification and feature extraction, and the tooth brushing actions of different users, such as frequency, hand-held toothbrush posture, tooth brushing specification of different areas and other detailed features are obviously distinguished; especially, the total number of members of a family user group is limited, and the identification complexity is greatly reduced.
When the machine learning mode is used for identification, the user terminal can input the tooth brushing characteristic information into the neural network obtained through machine learning training, and the matching degree of the tooth brushing characteristic information output by the neural network and each user is obtained; the machine learning comprises supervised learning, template matching learning or unsupervised clustering learning; and determining the identity information of the user corresponding to the tooth brushing characteristic information according to the matching degree.
In one example, a multi-layer neural network may be selected for user identification. Preselected tooth brushing characteristic information is input into the neural network. The neural network input is subjected to dimensionality reduction or feature nonlinear fusion by a feature dimensionality reduction method such as principal component analysis (principal component analysis), self-encoding network (autoencoder) or the like. Referring to a schematic diagram of neural network-based identity recognition shown in FIG. 5, features are input (F)1～FM) Dimension reduction into features (f) by self-coding networks1～fN) Wherein M is greater than N. Performing nonlinear fitting by k layers of neural networks, wherein each layer of neural network comprises j sub-networks, and the first layer of neural network is b11～b1j(ii) a Layer k neural network is bk1～bkj. Converge to sm (softmax) activation unit (activation function). The output of this example is the probability (%) of different users, and as shown in the figure, the probability value of user 1, the probability value of user 2, and the probability value of user i are respectively output, if the output results are all lower than the probability threshold, then it is suggested that a new user may appear.
Considering that the brushing specification of the user changes with time and other factors, particularly the brushing action during childhood brushing is greatly improved, in order to make the brushing analysis more accurate and to specify a more reasonable brushing specification, the model can be iteratively updated: in one example, the historical residue factor can be considered, and the corresponding brushing characteristic template of the user can be updated according to the current brushing characteristic information of the user, the stored historical brushing characteristic information of the user and the preset historical residue factor. Specifically, for the updated brushing characteristics template of the user i, the following formula can be referred to:
the brushing characteristic template of the user i is mu, the current brushing characteristic information of the user i is + (1-mu), and the user i has the historical brushing characteristics.
When a new user appears, the brushing characteristic template of the user can be stable after the completion of a plurality of brushing activities through the iteration of the formula. In the above example, the user terminal can not only identify the user of the unknown user when the unknown device is present, but can also potentially remind the user to misuse another toothbrush.
For different users, there are brushing specifications specified for their own features. The method may further comprise pre-establishing a brushing profile for the user, and the specific steps are as follows:
(1) according to the identity information of the user, the age of the user and the oral condition of the user are determined. Specifically, the age and the oral condition corresponding to the identity information are stored in a user database of the user terminal. According to the identity of the user, the age and the oral condition of the user can be directly found.
(2) Based on the user's age and oral condition, a user's brushing regimen is established.
(3) Storing the brushing profile of the user.
Different people have different oral cavity conditions, and in order to achieve a better tooth brushing effect, corresponding tooth brushing standard adjustment can be carried out according to the historical oral cavity health conditions of the user aiming at different user objects. In one example, the user scans cases through a mobile phone camera or introduces oral treatment history through a user case interface logged in the user terminal, and if the user terminal detects that oral symptoms are recently appeared, the user terminal immediately updates the working state of the toothbrush. For example, when a gum bleeding symptom is detected in a certain area in the oral cavity of the user, the user terminal controls the intelligent toothbrush to automatically turn down the vibration intensity or turn off the motor manually when the intelligent toothbrush is detected to be close to the area.
In one example, the user object is a child in a tooth replacement period, and the user can be reminded to bypass the corresponding area or to adopt different brushing strengths according to the tooth replacement position of the oral cavity. The tooth changing condition of the oral cavity can be completed through manual input of a user in interactive software, and the tooth changing area can also be found through a camera sampling oral cavity image and utilizing an image analysis method. Methods of image analysis include, but are not limited to, anomaly detection (anomaly detection) and machine learning. In another example, a neural network is trained by using the tooth-changing image sample with labels in the database, wherein the feature extraction network samples the superposition of a convolutional network (convolutional network) and max pooling, and the fitting network is realized by a multilayer neural network. In the training sample, the taken oral cavity image is divided into blocks, namely, the oral cavity image is divided into a plurality of areas, the block (tooth changing area) containing tooth changing in the block picture is marked with 1, and other normal areas are marked with 0. When the toothbrush reaches the tooth changing area, the tooth brushing motor can automatically stop or remind the user; in the manual toothbrush example, a user terminal or an intelligent toothbrush embedded indicator light would generate the alert signal.
In addition, the user terminal can call the user anonymization historical data for big data analysis and feature mining under the condition of obtaining the user consent. In one example, the system collects all data nodes showing gum bleeding symptoms and brushing history data for a certain time window for causal analysis (cause analysis); the user terminal quantifies factors related to symptoms, such as brushing intensity, brushing duration, brushing type, etc., to further optimize the brushing regimen for the corresponding user. In another quantitative analysis, the user terminal classifies healthy people and people with certain oral diseases, and effective tooth brushing characteristic information capable of distinguishing the two groups of people is extracted through analysis of tooth brushing specifications before symptoms appear; the probability of onset of certain oral symptoms by a user in the case of substandard brushing specifications is predicted by designing a classification learning algorithm (e.g., logistic regression analysis, supervised machine learning network with soft-max output activation function).
In the above-described example, the user object is a child who brushes teeth at first study, and the user terminal sets the tendency to the formation of the brushing motion specification for the brushing specification of the child. In this application example, the brushing analysis and feedback for children is focused to the action specification growth curve: including the brushing frequency, brushing efficiency, brushing duration, effective area, etc. of the user. The children brushing teeth standard is formed, and when the toothbrush is initially used, the judgment of the brushing teeth standard is set to be an extremely wide range so as to ensure that a user has brushing teeth learning interest without frustration. In the brushing analysis report, the user terminal can judge whether the user reaches the development of the brushing standard or not by quantifying the characteristic parameter repeatability of a plurality of times of brushing events of the user. In one example, we predict the next brushing characteristics by regression analysis (regression analysis) of the user's brushing characteristics and compare them to the actual brushing characteristics after the next brushing event is completed. If the deviation between the predicted parameter and the actual measurement is within the set range for a plurality of consecutive times, the user can be determined that the brushing regimen was completed and is embodied in the brushing analysis report.
The brushing regimen can be formulated into a number of phases, depending on the age level of the user: in one example, the first phase is set to the creation of brushing active areas, and the user needs to cover each active brushing area of the mouth during a brushing event according to guidance and prompting; the second stage is set as standard formation of tooth brushing action, and the user forms correct tooth brushing standard in a designated area, such as the outer side of incisors, and the user needs to brush up and down along the vertical direction; the third phase is set to the development of brushing efficiency, and in combination with the previous specification development results, the user must complete the brushing events for all the active areas with the correct action specification and achieve the specified brushing efficiency. At different stages, we can achieve the guiding effect through different interactive contents.
In another example, the user object is an adult or a user who has developed a brushing regimen, and the setting of the user terminal is inclined toward supervision of brushing regularity and improvement of the regimen. In the data analysis link, a brushing analysis report is generated periodically or according to a user request. The brushing analysis reports include, but are not limited to, a user's brushing data tracking, brushing efficiency, completion of brushing over a time period, and a brushing regimen that incorporates the user's oral health or medical history, among others.
By the mode, the personalized tooth brushing specification for each user can be established, the tooth brushing behavior can be improved by combining the actual conditions of the user, and the tooth brushing efficiency is improved.
In order to better guide the user to brush teeth in a correct manner, the method provided by the embodiment further includes: and prompting the brushing tooth specification corresponding to the identity information of the user to the user in a video, image or voice mode. Specifically, the user can be prompted on a display screen of the user terminal in the modes of interactive games, animations, short-film prompts and the like, a correct tooth brushing picture can be displayed, or the user is instructed to brush teeth according to a correct tooth brushing mode and tooth brushing duration in a voice mode.
Considering that there may be a new user performing a tooth brushing operation by using the smart toothbrush, or an old user accessing a user terminal by using a new device, that is, there may be 1) a user replacing a new brush head 2) a user replacing a new brush handle 3) a new user joining, in order to better identify and enter a user identity, the method further includes: and when the identity of the user cannot be identified, prompting the user to enter new user information through the display screen and/or the player. In one example, a user terminal pops up a prompt of 'detecting new equipment' and an interactive window through a display screen, and options such as 'existing user list' and 'adding new members' are set in the interactive window; the user selects the corresponding option according to the addition reason. In another example, the user terminal pops up a reminder only after the first or few brushings after detecting a new device; the system firstly performs feature extraction and autonomous learning on the tooth brushing information of the new equipment in a machine learning mode, and compares the tooth brushing information with existing tooth brushing historical data of a user; the information of the pop-up prompt may be "is the new device user x? And "other options". In this example, the user need only make manual device entries if the user terminal identifies an error.
