To wait for drawing input. 4A is a text data and image data input mode, and FIG. 4B is a drawing data input mode. First, as illustrated in FIG. 4A, the touch screen 11 may be implemented by being divided into a first implementation region 11a and a second implementation region 11b. When the cursor C and the mode conversion button T are implemented in the first implementation region 11a in the text data and image data input mode ([FIG. 4A]), the second implementation region 11b is displayed as shown in FIG. By implementing a 3 × 4 keyboard or the like, it is possible to input text data or image data for chatting by a user.

Thereafter, when the mode conversion button T is touched by the first touch terminal user, the mode conversion button T is converted to the drawing data input mode as shown in FIG. 4B, and then a pen icon for receiving the drawing data is implemented in the second implementation area 11b. Can be.

The drawing data generating means 15a of the drawing chat module 15 generates the touch event information and the meta information according to the drawing input through the touch on the touch screen 11 of the user of the first touch terminal, and then the touch event information. And meta information are matched to generate drawing data and stored in the storage unit 16.

Here, the meta information includes coordinate information based on a drawing input, time information, decompression information, and drawing setting information. The coordinate information is information on the coordinate change on the touch screen 11 according to the drawing input, the time information is information on the time at which the corresponding coordinate change occurred, and the decompression information is the touch screen 11 by the user of the first touch terminal. This is information about the change in pressure applied. In addition, the drawing setting information may include, for example, pen type, pen color, pen transparency, pen thickness information as drawing information on the drawing property by the first touch terminal user. The drawing setting information may be algorithmized to provide a detailed menu corresponding to the input of the setting button S in FIG. 4B.

The drawing data generating means 15a transmits a creation completion notice to the chat application 14 after the drawing data is stored in the storage unit 16.

The chat data generating means 15b is input by the user through the touch screen 11 as well as the drawing data generated by the drawing data generating means 15a in response to a request for transmission through the touch screen 11 of the first touch terminal user. It is analyzed whether "text data" by one character or "image data" by a user-specified image is further included. Here, the generation time of the text data and the image data can be generated regardless of whether the drawing data is generated before or after the drawing data.

According to the above analysis result, when the chat data generating means 15b does not include text data or image data, the chat data generating means 15b uses the drawing data as chat data, and the second touch terminal through the drawing chat server 30 connected to the communication network 20.

After generating data, the transceiver 12 is controlled to transmit the chat data to the second touch terminal 40 through the drawing chat server 30 connected to the communication network 20.

The chat data analyzing means 15c receives the chat data from the second touch terminal 20 through the drawing chat server 30. The chat data analyzing means 15c analyzes whether the chat data includes the touch event information, and then determines whether the received chat data includes the touch event information. The chat data analyzing means 15c extracts the drawing data from the chat data when the chat data includes the touch event information. On the contrary, if the touch event information is not included in the chat data as a result of the determination, the chat data analyzing means 15c extracts text data or image data from the chat data and implements the text or image on the touch screen 11.

The drawing data implementing means 15d extracts metadata from the drawing data extracted by the chat data analyzing means 15c and analyzes the change of the drawing coordinates over time by using time information and coordinate information included in the metadata. To implement the drawing image on the touch screen 11.

In addition, the drawing data implementing means 15d applies the drawing effect by using the decompression information and the drawing setting information included in the metadata extracted from the drawing image. For example, the first touch terminal user on the drawing image using the decompression information may differently apply the shading of the corresponding drawing image area by using the pressure change information applied to the touch screen 11. More specifically, when the pressure applied to the touch screen 11 by the user of the first touch terminal on the drawing image using the decompression information is relatively strong, the shade of the pen color is darkly applied. It is brightly applicable. Pen type, pen color, pen transparency, and pen thickness of a specific region of the drawing image by the first touch terminal user may be applied using the drawing setting information.

5 is a flowchart illustrating a process of generating drawing data in the drawing chat method according to the present invention. 1 to 5, when the user of the first touch terminal 10 requests to execute a chat application, the controller 13 loads the chat application 14 into the system memory area A ( S11).

Analyze the inclusion (S21). Meanwhile, in step S21, the second touch terminal 40 is also loaded with the chat application and the drawing chat module in the system memory area in the same manner as the first touch terminal 10, and the second touch terminal for convenience of description. Although described with reference to 40, it is actually performed by the drawing chat module in the second touch terminal 40.

The second touch terminal 40 determines whether or not the touch event information is included in the chat data according to the analysis of step S21 (S22).

When the chat data includes the touch event information as a result of the determination in step S22, the second touch terminal 40 extracts the drawing data from the chat data (S23).

After step S23, the second touch terminal 40 extracts metadata from the drawing data extracted in step S23 (S24).

After step S24, the second touch terminal 40 implements a drawing image by analyzing a change in drawing coordinates over time by using time information and coordinate information included in the metadata extracted in step S24 ( S25).

After step S25, the second touch terminal 40 applies the drawing effect to the drawing image implemented in step S25 using the decompression information and the drawing setting information included in the metadata extracted in step S24. (S26). For example, the shadow of the corresponding drawing image area may be differently applied using the pressure change information applied by the first touch terminal user on the touch screen 11 on the drawing image. That is, when the pressure applied on the touch screen 11 by the user of the first touch terminal on the drawing image using the decompression information is relatively strong, the shade of the pen color is darkly applied, and the shadow is brightly applied when the pressure is relatively weak. Do. In addition, the pen type, pen color, pen transparency, and pen thickness of a specific region of the drawing image by the first touch terminal user may be applied using the drawing setting information.

On the other hand, if the touch event information is not included in the chat data as a result of the determination in step S22, the second touch terminal 20 extracts the text data or the image data from the chat data received in step S21 before the text or The image is implemented on the touch screen (S27).
