JP2003036237A - Simultaneous common editing system for image and text using the internet browser - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve a problem in which it is necessary that dedicated software is conventionally installed for simultaneous common editing of an image through the Internet and that one person in a group performs a server function and notify an IP address, and the simultaneous common editing of text is further difficult. SOLUTION: The simultaneous common editing of the image and the text is made possible by a simplified method consisting only of an Internet browser based on an applet.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a control program for use in simultaneous joint editing of images, sentences, etc. by a plurality of users via the Internet.

[0002]

2. Description of the Related Art There is a method in which a plurality of users install software on their own computers and perform simultaneous joint editing of images through the Internet.

To handle a sentence in the prior art, there is a method of exchanging a sentence called a chat, which cannot be edited later such as deleting, or a method of drawing a character as an image.

[0004]

In the prior art, dedicated software had to be installed in each computer.

Further, in the prior art, one of a plurality of computers in the same group serves as a server, and it is necessary to notify everyone of the IP address. When using the dynamic IP, it is necessary to notify each time. .

In the prior art, either one of the following two methods was used in the case of simultaneous joint editing of text parts. The first method is that each person uses the chat function to copy the text on the window once, edit the text, and send the text-based text to the server.

The second method is to handle characters on an image basis and perform the operation with a mouse such as an eraser tool instead of operating the characters with a keyboard normally used for editing text. However, with any of these methods, it was not possible to directly co-edit text.

[0008]

The present invention uses the Internet, a server, Java (registered trademark) Script, a common gateway interface (hereinafter abbreviated as CGI), and a Java applet to simultaneously display images and texts only with a browser. To realize a system that enables collaborative editing work.

The present invention provides a service for realizing simple simultaneous image / text simultaneous collaborative editing work by using a browser capable of executing a Java applet that most Internet users already possess.

Since the present invention is a service provided on the HP, if only the group name is decided, it is not necessary to notify the IP address, which is required in the prior art.

In the present invention, as a method for handling text, in addition to the above-mentioned two methods of chat and image, a method called a text field using Java vector is newly prepared and is the same as the method of editing a normal text. Allows simultaneous simultaneous editing of sentences using the keyboard.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention as described above will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram showing the physical relationship of each element in the simultaneous image and sentence collaborative editing system using a browser according to the present invention. That is, the server 1, the first group 3, and the second group 4 are connected to the Internet 1.

The server 2 relays the communication among the users 5, 6 and 7 in the first group 3. Similarly, the server 2 relays communication between the users 8, 9 and 10 in the second group 4.

FIG. 2 is a flowchart of the simultaneous image and text simultaneous editing system using a browser according to the present invention.

When a user accesses this system, the program start step S1 is activated. When the program receives the nickname and the desired group name from the user on the HP in step S2, it checks in step S3 if there are blanks or non-alphanumeric characters in JavaS.
Determine using script. If it is included, the process returns to step S2 to newly acquire it. If not, continue.

In step S4, the server 2 using CGI is used.
To get a nickname already used by the group.

In step S5, it is determined using CGI whether or not the nickname is the same as an existing nickname. In case of duplication, the process returns to step S2 to acquire new nickname and group name. If not, continue.

In step S6, the applet is activated. Initialize variables, screen initialization, and threads for messages from the server.

In step S7, users in the same group perform simultaneous joint editing of images and sentences. Specifically, it manages the standby state and threads. In the standby state, a method is called for an operation for drawing (line, circle, square, etc.), text field window, chat window, login logout button, chat window, etc., and a necessary message is sent to the server 2. The thread rewrites images and texts in the message sent from the server 2 or manages the user.

In step S8, when the logout is performed, the operation is moved to step S9, and this program ends.

[0021]

EXAMPLE FIG. 3 shows an example in which an applet capable of simultaneously co-editing images and texts according to the present invention is activated on a browser, and shows a browser screen and various windows associated therewith.
FIG. 4 shows an example of activating a software capable of simultaneously co-editing images in the conventional technique.

Both have tool boxes and color selection windows 18, 21 and 22 necessary for drawing. Further, both of them are provided with chat windows 17 and 23 for exchanging non-editable texts by a plurality of mutually connected users. Further, both of them can draw a character as an image as shown in the drawing samples 16 and 20.

[0023]

As described above, the first advantage of the present invention over the prior art is that images can be co-edited simultaneously on the browser screen. In the prior art, special software had to be installed in advance in order to co-create images simultaneously. Specifically, in order to perform simultaneous joint editing of images, the browser screen 13 is used in the original name, while the dedicated software window 19 is used in the conventional technique. Since most Internet users already have a browser capable of executing Java applets, the present invention enables users to easily use services.

The second advantage of the present invention over the prior art is that the text field window 15 allows the user to write sentences to each other using the same keyboard input as in the ordinary text editing method, and delete written sentences. Also, simultaneous joint editing work such as addition became possible.

Further, according to the present invention, the user can perform the simultaneous collaborative editing work of the image and the sentence through the Internet by the simple method that only the browser is used, and the simultaneous collaborative editing of the image and the sentence can be performed in a more comfortable environment. Became.
