Communication method and system thereof in real time handwriting sharing method

The present invention relates to a communication method and a system of a real-time handwriting sharing method, and more specifically, to implement multi-way image by implementing the handwriting data input between the user terminal connected to the communication network in a central server rather than a one-to-one communication method And a method and system capable of handwriting communication.

Recently, with the rapid development of mobile communication terminals, various multimedia data can be transmitted in addition to the existing voice call. According to the development of these technologies, the needs of users are also very diversified, and many visual services are provided in response to these needs. For example, a direct facsimile service may be provided using a camera provided in a mobile communication terminal, or a map service using a GPS.

As one of such services, a communication method of an image unit between mobile communication terminals using a touch screen has recently been proposed. One example is a method of transmitting image data in real time between mobile communication terminals, such as Korean Patent Publication No. 10-2006-0099385, "Method for transmitting image data in real time." However, the previously proposed image communication or text message services merely propose a direct communication method between terminals, and it is technically difficult for all participants to share the same screen even if multilateral communication is impossible or possible.

For the same reason as above

The present invention provides a method and means capable of communicating with each other using handwriting or image data input from a user terminal.

At the same time, the present invention provides a method and means capable of synchronizing between terminals even in two or more multi-party communication situations.

It is also an object of the present invention to provide a means for enabling private communication.

In order to achieve the above technical problem,

In the handwriting communication service providing system comprising a communication server for providing a communication means between the user terminal having a touch screen and a pendam server connected to the communication server to control the transmission and reception of handwriting data,

The user terminal of the present invention includes a service requesting means and an input / output management means. The service requesting means is provided in the user terminal, and simultaneously or separately transmits an invitation request signal and a written message service request signal including the inviter information received from the user. The canvas input / output management means sets a predetermined canvas display area on the touch screen to transmit the writing data input from the user in the canvas display area in real time, and displays the canvas data received in real time on the canvas display area.

In this case, the text chat server includes a canvas database, a participant database, a canvas management means, and a participant management means. The canvas database stores canvas handwriting data. The participant database stores participant information participating in a service corresponding to each canvas data field generated in the canvas database. The canvas management unit allocates a new canvas data field to the canvas database when a service request signal is received from a user terminal, and reflects the input data transmitted from the canvas input / output management unit of each user terminal in real time to allocate the canvas data. The field is updated, and the canvas data of the canvas data field is transmitted to each participant terminal in real time. The participant management means allocates a participant data field corresponding to the canvas data field assigned by the canvas management means to the participant database when a service request signal is received from a user terminal, and receives an invitation request signal from the user terminal. The participant request message is transmitted to the invitee, and when at least one of a service request signal and a participation response message for the invitation request signal is received, the participant database is updated to reflect the changed participant information.

The handwriting data transmitted by the canvas input and output management means may include relative coordinates and control information in a canvas display area of data input from a user in a vector data structure.

In addition, the canvas input and output management means may transmit the data input from the user as handwriting data of the bitmap data structure.

In addition, the service requesting means may further receive a secret service from the user and transmit it with the service request signal. In this case, the canvas management means allocates a new canvas data field as a private property when a secret service request signal is received together with the service request signal.

In a method of providing a handwriting communication service comprising a communication server providing a communication means between user terminals and a text message server connected to the communication server and controlling handwriting data transmission and reception, the present invention includes the following steps.

In the first step, the user terminal receives input of inviteer information and a service request.

In step 2a-1, the text message server receives an inviter information and a service request signal from a user terminal and allocates a storage area for storing canvas data and corresponding participant data. In step 2a-2, the message server sends the participation request message to the received invitee. In step 2a-3, when the participation acceptance message is transmitted from the inviter's user terminal, the message server updates the participant data storage area.

In step 3-1, each user terminal receives handwriting data from the user and transmits the handwriting data to the talk server. In step 3-2, the text chat server receives and collects the handwritten data transmitted from each participant's user terminal and transmits the collected handwritten data to the user terminal of each participant. In step 3-3, steps 3-1 and 3-2 are periodically repeated.

On the other hand, the present invention is a method for providing a handwriting communication service having a communication server for providing a communication means between the user terminal and a text message server connected to the communication server to control the transmission and reception of the handwriting data.

In the first step, the user terminal receives input of inviteer information and a service request. In step 2b-1, the message server receives the invitation information and the service request signal from the user terminal and transmits the message message request message to the inviter. In step 2b-2, when the participation acceptance message is transmitted from the inviter's user terminal, the text chat server allocates a storage area for storing canvas data and corresponding participant data and updates the participant data storage area.

In step 3-1, each user terminal receives handwriting data from the user and transmits the handwriting data to the talk server. In step 3-2, the writing message server receives and collects handwriting data transmitted from each participant's user terminal and transmits the collected handwriting data back to each participant's user terminal. In step 3-3, steps 3-1 and 3-2 are periodically performed.

The method may further include extracting the relative coordinates and the control information from the canvas display area and converting the writing data input from the user into the vector data structure.

The method may further include converting the handwritten data input from the user in the step 3-1 into a bitmap data structure.

From the structural features of the present invention described above,

The communication system of the handwriting sharing method according to the present invention enables input and communication of handwriting or image type between user terminals and at the same time allocates a separate database from the server to collect and share handwriting data input from each user terminal. Synchronization is possible even when an abnormal person communicates.

In addition, the present invention can be provided with a secret communication function to limit the participation of others constantly.

That is, the user terminal 200 collectively refers to a PDA, a smart phone, and other devices equipped with a touch screen having an input means such as a touch screen. In this case, the touch screen means that if a person's hand or an object touches a character or a specific location on the screen (screen) without using a keyboard, the input screen is directly inputted on the screen so that the location can be detected and processed by the stored software. It refers to a device that can be used and it is irrelevant to its type, such as a contact capacitance method or a pressure resistive film method. Each structure is demonstrated below.

The service requesting means 210 will be described with reference to FIG. 3.

The service requesting means 210 is provided in the user terminal 210 as described above, and is preferably provided in the form of an Open API in order to facilitate interworking and integration with other applications, which will be described in this embodiment. The same applies to the constituent means.

The service requesting unit 210 receives an invitation request signal and a written message service request signal from the service applicant. Here, the write message service request signal means a request for allocating a database field in which shared data is to be stored in order to receive a service for sharing handwritten data according to the present embodiment. In addition, the invitation request signal is a kind of friend invitation message that refers to a message that one wants to create or invites another person to the already created handwriting sharing service. The invitation request signal may include identification data for distinguishing the service from other services when the handwriting sharing service has already been generated, and may also include a telephone number or a user ID for the invitee. In addition, it may include additional information such as various control codes and invitees.

Meanwhile, the service request signal and the invitation request signal may be transmitted simultaneously or separately. In other words, the service requester may first request for a service and then invite a friend after being allocated a certain storage space, or may simultaneously invite a friend. This is described in detail in the process. In addition, after the handwriting data synchronization process, which will be described later, each participant may send an invitation request signal to another person who will participate in the corresponding handwriting sharing service according to the authority granted by the service applicant.

Transmit to the realm server 100 in real time. In this case, if there is no input from the user, such transmission may be omitted and wait until the input is started. In addition, the canvas input and output management means 220 is to output the canvas display area (W) of the user terminal 200 to the updated canvas data transmitted in real time from the text chat server 100.

On the other hand, the input and output management means 220 should be converted into a digital signal / data format in order to transmit the electrical handwriting data input from the canvas display area (W) to the talk server 100, in this case, such as bitmap or vector format Data structures can be used.

In the case of converting to the vector data structure method, relative coordinates and control information in the canvas display area are extracted from the data input from the user and transmitted to the text chat server 100.

With reference to FIG. 3, each structure of the text chat server 100 is demonstrated.

The canvas database 125 stores canvas canvas handwriting data. Here, a field in which one canvas handwriting data is stored is a canvas identification data field in which canvas identification data allocated to distinguish each of the text message services generated as shown in FIG. 6 is stored and transmitted from the user terminal 200. A handwriting data field in which handwriting data is stored and an attribute field in which various attributes such as whether the canvas is disclosed or closed (described in detail in Embodiment 2) are stored. Meanwhile, various data fields may be added according to a purpose, such as a background data field in which image data to be inserted as a background is stored in the canvas display area according to a user's selection.

As shown in FIG. 7, the participant database includes a canvas identification data field storing identification data of a corresponding canvas data field and a participant data field storing personal information and authority information for each participant.

When the canvas management unit 120 receives the service request signal from the user terminal 200, the canvas management unit 120 allocates a new canvas data field corresponding to one of the text message services generated as shown in FIG. 6 to the canvas database 125. A new service is created by assigning unique identification data of the service.

In addition, the canvas management unit 120 updates the assigned canvas data field by reflecting handwritten data input and transmitted in real time from the canvas input / output management unit 220 of each user terminal 200 described above, and the canvas of the canvas data field Data is transmitted to each participant terminal in real time. In addition, the canvas data field is updated to reflect the background setting or the attribute of the corresponding handwriting sharing service that is additionally transmitted.

The participant management unit 110 allocates a participant data field as shown in FIG. 7 to correspond to each handwriting sharing service generated by receiving a service request signal from the user terminal 200. The participant management unit 110 updates the canvas identification data field for identifying the corresponding service and the personal information of each participant according to the participant's change. For example, when an invitation request signal is received from a service applicant or another user's user terminal 200, a participation request message is transmitted to the inviter. In this case, a means for transmitting a reply message to the corresponding message or a separate participation permission is allowed. Providing a means to receive the message back to confirm the participation from the invitee. When there is a change in a participant such as a participation response message for the service request signal or an invitation request signal or a communication interruption of some of the participants, the participant data field allocated to the participant database is updated to reflect the changed participant information.

<Example 2>

The second embodiment is a case where a private text chat service is added.

In order to request the privately speaking service privately, the user further inputs whether the secret service is provided through the service requesting means 210, and the service requesting means 210 transmits it together with the service request signal or the identification data of the previously created privately speaking service. Can be sent together.

The canvas management unit 120 generates a new service by allocating a new canvas data field as a private property when the secret service request signal is received together with the service request signal, and when the secret service request signal is transmitted together with the identification data of the pre-created text message service. The property of the pre-created text message service will be made private.

2. Process

The process according to the present invention can be divided into two types: a new service generation process of requesting a service and inviting a friend to be assigned a new handwriting sharing service, and a handwriting sharing process of sharing handwriting while a generated handwriting sharing service is provided. Is it.

A new service creation process will be described with reference to FIG. 8.

First, the user terminal 200 receives the inviter information and the service request from the user and transmits the message to the message server (S10). Next, as described above, the Phildam server 100 receives the inviter information and the service request signal from the user terminal 200 and allocates a storage area for storing canvas data and corresponding participant data to generate a new handwriting sharing service. In operation S20, the information of the service applicant is updated. Thereafter, the text chat server 100 checks whether the invitation is accepted by transmitting a participation request message to the received invitees (S30). Finally, when the inviter accepts the participation, the text chat server updates the participant data storage area, that is, the assigned participant data field, and includes it as a subject of the handwriting sharing process to be performed later.

Meanwhile, another embodiment of the new service creation process will be described with reference to FIG. 9. There is a difference in the update phase of participant information. In the previous example, a new service is created according to the service request, and a participant data field is generated along with storing the applicant's information. However, in this embodiment, the process is performed after the invitation of the inviter.

That is, the process of generating the canvas request and the other party's invitation signal is the same (S10), but in the present embodiment, first, a message for inviting the inviter to participate is transmitted (S30), and if the inviter accepts the participation, the new service Generate and generate a data field in which the participant data will be stored (S45).

On the other hand, the function for inviting the other party is possible at any stage, including the handwriting sharing process to be described later, except as described in the new service creation process, and each participant, in addition to the service applicant, may be invited according to the information of each authority. .

A handwriting sharing process will be described with reference to FIGS. 10 and 5.

After the new service is generated (0t), as shown in FIG. 5, each user terminal (establisher and participant) receives handwriting data and transmits it to the talk server (DB) (S50). Thereafter, the message server (DB) collects the transmitted writing data and transmits the collected writing data back to the user terminal of each participant (S60). In this case, each terminal state after one cycle 1t is in a state in which each user terminal (establisher and participant) is synchronized as shown in FIG. 5. Thereafter, the above process is repeated to proceed with the handwriting sharing process (S70).

Although the preferred embodiments of the present invention have been described above, the technical spirit of the present invention is not limited to the above-described preferred embodiments, and various handwriting sharing methods are provided within the scope not departing from the technical spirit of the present invention specified in the claims.
