In addition, the embodiment of the invention can also analyze the drawing track of the first intelligent terminal to obtain corresponding annotation information, and send the drawing track and the corresponding annotation information to the second intelligent terminal; the second intelligent terminal can be a terminal used by a parent, so that the embodiment of the invention can enable the parent to know the current situation of the child in real time through the current drawing track of the child, for example, to know whether the child is happy or too young currently, and for example, to know what the current internal needs of the child are.

In summary, the embodiment of the invention provides a children expression requirement and a channel for communication between children and parents, which can not only meet the requirements of children on emotion, emotion and expression of understanding things, improve the ability of children to describe things and express themselves, but also improve the flexibility and convenience of drawing operation; moreover, information can be transmitted between the children and the parents, and the bridge for the parents to know the children is increased.

In practical applications, the bracelet 200 can be worn on the wrist of the user, and the positioning device 203 can be used for positioning the wrist. In the embodiment of the present invention, the position of the wrist located by the position finder 203 may be used as the origin of coordinates in a three-dimensional space.

The signal transmitting module 201 may specifically include: the system comprises a motion sensor and a signal transmitter, wherein the signal transmitter can send out a wireless signal by taking a positioning instrument 203 as a coordinate origin to form a three-dimensional space; the motion sensor may be configured to detect displacement information of the hand or the finger of the user in the three-dimensional space, so that the position finder 203 may calculate an operation coordinate of a position point corresponding to the hand or the finger of the user when each drawing operation is performed according to the displacement information obtained by the motion sensor.

It should be noted that the above bracelet 200 is only an example of a wearable device, and actually, a person skilled in the art may use various wearable devices to implement the trajectory processing method of the present invention, and the embodiment of the present invention does not limit the specific wearable device.

Further, the step of displaying the virtual drawing board may specifically include:

and displaying the virtual drawing board in a plane or curved surface form in an optical mode. Wherein, the curved surface may include: the drawing method comprises the following steps of generating a corresponding plane or three-dimensional drawing track aiming at continuous operation coordinates when a virtual drawing board in a curved surface form is adopted, wherein the drawing method comprises a cylindrical curved surface, a hyperboloid and an irregular curved surface.

Referring to fig. 3, a schematic diagram of a virtual drawing board and a drawing trace corresponding to the virtual drawing board of the present invention is shown, where the virtual drawing board C may be located on a vertical plane XOY or may form a certain angle with the vertical plane XOY. It can be understood that the embodiment of the invention can generate the corresponding drawing track in real time and display the generated drawing track in real time, so that a user can obtain the experience equivalent to the physical drawing board. In addition, the light color corresponding to the drawing track may be different from the optical color corresponding to the virtual drawing board, so that the user can clearly define the drawn drawing track.

In an alternative embodiment of the invention, the operation space comprises: in a three-dimensional space, there may be a case where the operation coordinate is not located on the virtual drawing board, in this case, the step 102 may first project the operation coordinate on the virtual drawing board to obtain a corresponding projection coordinate, and then generate a corresponding drawing track for consecutive projection coordinates according to a trigger time of the drawing operation, where the drawing track may have a corresponding start point and an end point. It is to be understood that the embodiment of the present invention does not impose a limitation on the specific generation process of the drawing trace.

And 103, sending the drawing track to a server.

In practical applications, the embodiment of the present invention does not limit the specific trigger time for sending the drawing trace to the server. For example, the drawing trace may be sent to the server upon determining that the user completed a complete drawing. The process of determining that the user completes one complete drawing specifically may include: and detecting no operation coordinate within a preset time interval, and indicating that the user finishes one complete drawing because the drawing is stopped. Or, the process of determining that the user completes a complete drawing specifically may include: the distance between the operation coordinate generated in the latest time period in the drawing track and other operation coordinates exceeds a first threshold, in which case the user can be explained to restart a new drawing. Or, the process of determining that the user completes a complete drawing specifically may include: the overlap of the operation coordinate generated in the last time period in the drawing trace with other operation coordinates exceeds a second threshold, for example, the user redraws a floret shape on the face area of the drawing trace shown in fig. 3, in which case the user may be said to restart a new drawing.

In an optional embodiment of the present invention, the virtual drawing board or the first intelligent terminal may be provided with a preset control, and the preset control specifically includes: and starting a drawing control, a brush selecting control with different colors or different thicknesses, an eraser control, a finishing control and the like, so that the embodiment of the invention can respond to the triggering operation of the user on the preset control and execute corresponding drawing operation. For example, after receiving a trigger operation of a user for starting a drawing control, the display of the virtual drawing board may be triggered; for another example, after receiving a trigger operation of a user for a brush pen selection control, a current brush pen with a corresponding color and a corresponding thickness may be selected, and a drawing track adapted to the current brush pen may be selected on the virtual drawing board, where for example, the color of the current brush pen is red, the thickness of a line is 3, the color of the drawing track may also be red, and the thickness of the line may be 3; for another example, after receiving a trigger operation of a user for an eraser control, the eraser control may be used to erase the drawing trace; or after receiving the trigger operation of the user for completing the control, the drawing can be shown to be completed, so that the drawing track can be sent to the server.

In summary, according to the embodiment of the invention, the user can generate the drawing operation through the first intelligent terminal, so that the requirements of the children on the aspects of emotion, emotion and expression of understanding of things can be met, and the flexibility and convenience of the drawing operation can be improved. For example, when a child has a need to think about a mother before afternoon nap, the corresponding need can be expressed by drawing the mother; for another example, when a child has a demand for eating bananas, the corresponding demand can be expressed by drawing bananas, and the like. For another example, when the child is happy, a smiling face may be drawn to release the mood, etc. Alternatively, the child may draw a rocket trail similar to that of FIG. 4 to express a gift or the like that the child wants.

In addition, because the first intelligent terminal has the portable property, in practical application, the drawing operation of the embodiment of the invention can be carried out on a wall, a desk or a space without an entity support, so the portable property of the wearable device can meet the expression requirements of a child user at any time and any place.

Method embodiment two

Referring to fig. 4, a flowchart illustrating steps of a second embodiment of a trajectory processing method according to the present invention is shown, which may specifically include the following steps:

step 401, displaying a virtual drawing board;

step 402, detecting an operation coordinate generated by a user in an operation space corresponding to a first intelligent terminal;

step 403, generating a corresponding drawing track according to the operation coordinates;

step 404, displaying the drawing track on the virtual drawing board;

step 405, sending the drawing track to a server.

In practical applications, the execution order of step 401 and step 402 is not limited in the embodiment of the present invention, and the two steps may be executed sequentially or in parallel.

Method embodiment three

Referring to fig. 5, a flowchart of a third step of an embodiment of a track processing method according to the present invention is shown, which specifically includes the following steps:

step 501, detecting an operation coordinate generated by a user in an operation space corresponding to a first intelligent terminal;

502, generating a corresponding drawing track according to the operation coordinates;

step 503, sending the drawing track to a server;

with respect to the first embodiment of the method shown in fig. 1, the trajectory processing method of this embodiment may further include:

step 504, receiving the drawing track sent by the server and the annotation information corresponding to the drawing track; or

And 505, sending the drawing track and the corresponding annotation information to the intelligent terminal corresponding to the first intelligent terminal.

In an embodiment of the present invention, the annotation information may be used to explain the meaning of the drawing track, so that a user or other users of the first intelligent terminal can know the object or the expressed information described by the drawing track, so as to enable, for example, a parent to know the current status of the child in real time through, for example, the current drawing track of the child, for example, to know whether the child is happy or unhappy currently, and, for example, to know what the current internal needs of the child are.

In an optional embodiment of the present invention, the annotation information may specifically include: object information and/or expression information. The object information may be used to indicate an object described in the drawing trace, and the object may be an object similar to fig. 3 or a person. The expression information can be used for expressing the emotion or emotion expressed by the drawing track. For example, when the object described by the drawing track is a character avatar, the drawing track may express a happy mood when the eyebrows and eyes of the character avatar are bent and the mouth is wide open. For another example, when the eyebrows of the figure are picked up and the mouth is closed to a slant line, the drawing trace can express an angry emotion.

In an optional embodiment of the present invention, after receiving the drawing track and the annotation information corresponding to the drawing track sent by the server, the annotation information may be played in a voice form, and a preset interface may be used to collect feedback information of the drawer on the annotation information.

In practical application, a mapping relationship between the first intelligent terminal and the second intelligent terminal may be established, and in this way, step 505 may determine, according to the mapping relationship, the second intelligent terminal corresponding to the first intelligent terminal, and send the drawing track and the annotation information corresponding to the drawing track to the second intelligent terminal corresponding to the first intelligent terminal through any communication mode, such as 2G, 3G, 4G, mobile network, WIFI, and the like. For example, a mobile phone or a mobile phone number of a parent may be bound to the first intelligent terminal in advance, and the drawing track and the corresponding annotation information thereof may be sent to the mobile phone number of the parent in a short message manner.

Method example four

Referring to fig. 6, a flowchart illustrating a fourth step of an embodiment of a trajectory processing method according to the present invention is shown, which may specifically include the following steps:

601, receiving a drawing track sent by a first intelligent terminal;

step 602, analyzing the drawing track to obtain corresponding annotation information;

step 603, sending the drawing track and the corresponding annotation information to the first intelligent terminal and/or the second intelligent terminal.

The embodiment can be applied to a client or a server side, the server can be a common server or a cloud server, and because the embodiment can analyze and process the drawing track through the server side, the advantage that the computing resources of the server side (for example, cloud resources such as a large database and a large number of computing devices for computing can be arranged in the cloud server) are rich can be exerted, so that the analysis efficiency and the analysis precision of the drawing track can be improved.

The second intelligent terminal may be a terminal other than the first intelligent terminal, and may have a preset mapping relationship with the first intelligent terminal. According to the embodiment of the invention, a user or other users of the first intelligent terminal can know the object or the expressed information described by the drawing track, so that parents can know the current condition of the child in real time through the current drawing track of the child.

The embodiment of the invention can provide the following technical scheme for analyzing the drawing track:

technical solution 1

In technical solution 1, the step 602 of analyzing the drawing trajectory to obtain corresponding annotation information may specifically include:

a1, determining the similarity between the drawing track and a preset drawing track;

step A2, according to the label information of the preset drawing track with the similarity meeting the preset similarity condition, determining the annotation information corresponding to the drawing track.

In an optional embodiment of the invention, the preset drawing trajectory comprises: at least one of a simple drawing track, a basic drawing track and a historical drawing track of at least one intelligent terminal. The simple strokes are in a planar and stylized form and a simple and elegant stroke method, and can generally draw the main characteristics of the object image by using the simplest lines and planar forms; the basic drawing can be a relatively simple drawing method. As the drawing technology of children, especially infants, is generally low, in practical application, for example, the simple drawing tracks of the children and the basic drawing tracks of the children can be collected from the national or worldwide drawing databases of the children, so that the richness and the analysis precision of the preset drawing tracks are ensured. Or the children sketch trajectory and the children basic drawing trajectory can be crawled from a vertical website related to the children drawing, and the specific acquisition mode of the sketch trajectory and the basic drawing trajectory is not limited in the embodiment of the invention.

In practical application, the server may collect the history drawing tracks uploaded by the client, and use the history drawing tracks as the preset drawing tracks, or select the history drawing tracks meeting preset rules from the history drawing tracks as the preset drawing tracks.

In practical applications, the step a1 may determine the similarity between the drawing track and a preset drawing track by using a graph matching method, and if the similarity ranges from 0% to 100%, where 0 indicates no similarity and 100% indicates the same similarity, the preset similarity condition may specifically be that the similarity is greater than a similarity threshold, where the similarity threshold may be determined by a person skilled in the art according to practical application requirements, and may be, for example, a value of 85% or 90%.

In an embodiment of the present invention, the label may be used to identify a drawing track, and specifically includes: object information and/or expression information, as well as author information, drawing time, etc. In a specific implementation, the label of the preset drawing track may be obtained in advance. Wherein, the label can be directly obtained from the description information of the drawing track in the children drawing database (for example, the description information can describe what the drawing track is, what emotion is expressed by the lyric, etc.); or, the label can be directly obtained from the information of the drawing track included in the webpage to which the drawing track belongs; alternatively, the label may be obtained by analyzing characteristics such as a shape and a detail of the preset drawing trace. It can be understood that the embodiment of the present invention does not limit the specific obtaining manner of the label of the preset drawing track.

In an application example of the present invention, the number of the preset drawing trajectories is 10000, and the number of the preset drawing trajectories having a similarity exceeding 90% to the drawing trajectory corresponding to fig. 4 may be 10, the annotation information of the drawing trajectory corresponding to fig. 4 may be obtained according to the label of the 10 pairs of preset drawing trajectories: provided is a rocket.

In summary, in the technical solution 1, the annotation information corresponding to the drawing track is determined according to the label information of the preset drawing track whose similarity meets the preset similarity condition, which has the advantages of simple operation and high processing efficiency, and more accurate annotation information can be obtained under the condition that the richness of the preset drawing track can be ensured, that is, the analysis precision of the drawing track can be improved.

Technical solution 2

In technical scheme 2, the step 602 of analyzing the drawing trajectory to obtain corresponding annotation information may specifically include:

b1, clustering the intelligent terminals according to the historical drawing tracks, the historical annotation information and/or the corresponding feedback information;

and step B2, acquiring a target intelligent terminal with the same category as the first intelligent terminal, and determining annotation information corresponding to the drawing track according to historical annotation information corresponding to the historical drawing track of the target intelligent terminal.

In the embodiment of the present invention, the annotation information may be feedback information corresponding to the annotation information generated by the user, where the user may be the painter itself, or a related user such as a parent of the painter, and the feedback information may reflect the recognition degree of the user for the annotation information. In practical applications, the feedback information may include: the evaluation information (such as evaluation level and evaluation score), shared information, saved information, and correction information, etc. if the evaluation score of the user with respect to the comment information is high, or if the user saves or shares the comment information, it indicates that the user has a high recognition degree with respect to the comment information. Alternatively, the user may generate correction information for the annotation information, for example, by modifying the history drawing trace from "happy" to "sad" with respect to the history expression information, and the corrected history expression information may be used as the final history annotation information.

Step B1 may be configured to cluster the historical annotation information and/or the corrected historical annotation information with the recognition degree of the user exceeding the recognition degree threshold, so as to classify the intelligent terminals having the same or similar drawing habits and/or expression habits into the same category. For example, some children like to express "happy" by a gesture of putting on both hands, they can be classified into the same type; while some children like to express "impatience" by a gesture of putting both hands on, they can be classified into the same category.

Step B2 may obtain a target intelligent terminal having the same category as the first intelligent terminal, and since the target intelligent terminal and the first intelligent terminal have the same or similar drawing habit and/or expression habit, the annotation information corresponding to the drawing track may be determined by using the historical annotation information that has been generated by the target intelligent terminal. For example, the target smart terminal has a history drawing track 2 and history annotation information 2 which are not present in the first smart terminal, in addition to the history drawing track 1 and history annotation information 1 which are the same as those of the first smart terminal, and when the first smart terminal has generated a drawing track similar to the history drawing track 2, the annotation information of the drawing track can be obtained according to the history annotation information 2.

In practical applications, in order to improve the accuracy of the annotation information, the annotation information of the drawing trace can be obtained according to the historical annotation information and/or the corrected historical annotation information, wherein the recognition degree of the historical annotation information exceeds a recognition degree threshold value. It can be understood that, in the embodiment of the present invention, a specific process of determining annotation information corresponding to a drawing track according to history annotation information corresponding to the history drawing track of the target intelligent terminal is not limited.

Technical solution 3

In technical solution 3, the step 602 of analyzing the drawing trace to obtain corresponding annotation information may specifically include:

c1, extracting the characteristics of the drawing track;

and step C2, inputting the characteristics into a drawing recognition model, and outputting annotation information corresponding to the characteristics by the drawing recognition model.

Technical scheme 3 can utilize drawing recognition model to carry out the discernment of drawing the orbit. In practical application, a drawing track sample and corresponding annotation information generated by a child user can be collected through a client running on a first intelligent terminal or other clients, and the drawing track sample is trained to obtain a corresponding drawing recognition model, wherein the drawing recognition model has recognition capability of a drawing track, specifically, a preset feature of the preset annotation information can be matched with a feature of the drawing track, and if the matching is successful, the annotation information of the feature can be recognized as the preset annotation information. The preset comment information may include: at least one thing and corresponding expression, at least one character and corresponding expression, and the like. In addition, a drawing recognition model with multiple types of recognition capabilities can be established, wherein the number of types can correspond to the number of objects and corresponding expressions, and the like.

Technical solution 4

With respect to any one of technical solution 1, technical solution 2, and technical solution 3, in technical solution 4, the step 602 of analyzing the drawing trajectory to obtain corresponding annotation information may further include:

and D1, calibrating the annotation information corresponding to the drawing track according to the feedback information of the user on the historical annotation information corresponding to the historical drawing track of the first intelligent terminal, so as to obtain calibrated annotation information.

The step D1 may calibrate the annotation information obtained in any one of claim 1, claim 2, and claim 3 using the feedback information, so as to improve the accuracy of the annotation information.

In practical application, the annotation information of the drawing track can be calibrated according to the historical annotation information and/or the corrected historical annotation information, wherein the recognition degree of the historical annotation information exceeds a recognition degree threshold; the calibration can improve the accuracy of the annotation information because the historical drawing track of the first intelligent terminal corresponds to the historical annotation information which can reflect the drawing habit and/or the expression habit of the current user. For example, the history annotation information corresponding to the history drawing track of the first intelligent terminal indicates that the user of the first intelligent terminal is familiar with the expression of "happy" by the eyebrows in the shape of "regular eight", and the label of the eyebrows in the shape of "regular eight" in the preset drawing track in technical scheme 1 includes "sad", so that technical scheme 4 can better achieve the correction effect.

Technical solution 5

With respect to any one of technical solution 1, technical solution 2, and technical solution 3, in technical solution 5, the step 602 of analyzing the drawing trajectory to obtain corresponding annotation information may further include:

and E1, calibrating the annotation information corresponding to the drawing track according to the relevance between the current environment information of the first intelligent terminal and a preset theme, so as to obtain calibrated annotation information.

In this embodiment of the present invention, the current environment information of the first intelligent terminal may be used to indicate an environment where the first intelligent terminal is located, and may specifically include: the environment information may specifically include at least one of the following information: time information, location information, light information, weather information, and the like.

The embodiment of the invention can pre-establish the mapping relation between the preset environment information and the association degree of the preset theme, wherein the preset theme can be related to festivals (child birthdays, child festivals) and child activities. For example, the preset time range corresponding to the preset topic "children section" is "6 months, 1 days and 5 days before", when the current time information of the first intelligent terminal is in the preset time range, the "children section" may be used to calibrate the annotation information, for example, a "cheerful" atmosphere expressed by the "children section" is added to the calibrated annotation information. Similarly, the preset theme may further include: themes corresponding to festivals of children such as Christmas, Halloween and the like.

For another example, the preset theme "zoo" may have a corresponding preset position range, and when the current position information of the first intelligent terminal is in the preset position range, the "zoo" may be used to calibrate the annotation information, for example, adding an atmosphere such as "lovely", "nature", and the like expressed by the "zoo" to the calibrated annotation information. Similarly, the preset theme may further include: themes corresponding to children's places such as ' amusement parks ' and ' ocean halls ', and the like.

In summary, according to the technical scheme 5, the annotation information corresponding to the drawing track is calibrated according to the association degree between the current environment information of the first intelligent terminal and the preset theme, so that the degree of engagement between the annotation information and the current environment information can be improved, and therefore, the accuracy of the annotation information can be improved.

The above-mentioned technical solution 1-technical solution 5 are used to describe the analysis process of the drawing track in detail, and it can be understood that a person skilled in the art can adopt any one or combination of the above-mentioned technical solution 1-technical solution 5 according to an actual application requirement, or can also adopt other analysis processes of the drawing track, for example, an artificial intelligence technology can be used to simulate the expression thinking of the drawing track by a current user and/or other users, and obtain annotation information and the like corresponding to the drawing track according to the expression thinking, and the embodiment of the present invention does not limit the specific analysis process of the drawing track.

In summary, in the embodiment of the present invention, the intelligent terminal corresponding to the first intelligent terminal may be a terminal used by a parent, so that the parent can know the current situation of the child in real time through the current drawing track of the child, for example, know whether the child is happy or too hard at present, and for example, know what the current internal needs of the child are. Therefore, the bridge that parents know about children can be increased.

Example of the method

To better understand the embodiments of the present invention, an example of a trajectory processing method of the present invention is provided herein.

In this example, the intelligent terminal may provide a virtual drawing board, such as an optical drawing board, to the child in the form of light beam projection, so that the child draws his or her expression or a desired gift or even mood at the moment through the optical drawing board. Specifically, the client running on the intelligent terminal can detect an operation coordinate generated by a child in an operation space corresponding to the first intelligent terminal, generate a corresponding drawing track according to the operation coordinate, and send the drawing track to the server.

The server can be provided with cloud resources such as a large database and a large number of computing devices for computing, and can analyze the drawing track by using the cloud resources and technologies such as pattern matching, pattern recognition and artificial intelligence to obtain corresponding annotation information; and the server can calibrate the annotation information corresponding to the drawing track according to the feedback information of the user on the historical annotation information corresponding to the historical drawing track of the first intelligent terminal, so that the calibrated annotation information conforms to the drawing habit and/or expression habit of the current child. Or, the server may calibrate the annotation information corresponding to the drawing track according to the association degree between the current environment information of the first intelligent terminal and the preset theme, so that the degree of engagement between the annotation information and the current environment information can be improved, and therefore, the accuracy of the annotation information can be improved.

Further, the server can also send the drawing track and the corresponding annotation information to the intelligent terminal corresponding to the parents.

Assuming that a child clicks a "completion" control after drawing a rocket figure through the optical drawing board, the first intelligent terminal can send the figure to a server or a second intelligent terminal; the server or the second intelligent terminal can know that the object corresponding to the graph is the rocket through analysis, and can know that the birthday of the child is close, so that the annotation information of the rocket and birthday gift can be obtained, and further the graph and the annotation information can be sent to a client account of a preset contact, such as mom. The mother and other preset contacts know that the child wants to remind her of the well-spoken birthday gift of the rocket toy through the annotation information and do not forget to send the birthday gift to the child.

To sum up, the embodiment of the invention provides a channel for expressing demands of children and communicating children with parents, which can not only meet the demands of children in the aspects of emotion, emotion and expression of understanding things, improve the capability of describing things and expressing themselves by children, but also improve the flexibility and convenience of drawing operation; moreover, information can be transmitted between the children and the parents, and the bridge for the parents to know the children is increased.
