Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of synthesizing data held by a computer connected to a communication line with other data and information of a user who is trying to obtain the data, and The present invention relates to a data synthesizing and displaying method, a data synthesizing and displaying device, and a recording medium having recorded thereon a data synthesizing and displaying program, which are displayed on a screen.

[0002]

2. Description of the Related Art As a conventional system for displaying a symbol holding user information as a three-dimensional virtual object in a three-dimensional virtual space, a "community place" is used.
And "interspace".

In these virtual space display devices, a three-dimensional virtual object that moves in a three-dimensional virtual space in conjunction with a viewpoint moving operation in the three-dimensional virtual space displayed on a computer operated by a user is previously stored. By synthesizing and displaying the three-dimensional virtual space data registered in the virtual space management device, it is possible to communicate with another user who is actually in a remote place.

[0004] Also, there are "Netscape Communicator" and "Internet Explorer" as software for displaying data held by a computer connected to a communication line on another computer connected to the communication line via the communication line. These software are video data,
Image data, audio data, and text data can be edited and displayed.

[0005] In order to perform a predetermined operation at a predetermined timing or to perform a predetermined operation in response to a user's operation in data referred to using data display software such as the Netscape Communicator or Internet Explorer. There is JavaScript as a programming language in which a program can be described.

[0006]

In a conventional data display device for referring to data via a communication line, the data is not virtual space data registered in a specific server as a multiplayer virtual space. As long as the information of other referrers cannot be displayed in a timely manner, so-called anonymity was maintained between the referrers. However, it is information that can be viewed by an administrator of the server, and cannot be displayed on the data display device in order for the referrers to know each other's information.

[0007] When the virtual space data registered in a specific server as a multiplayer virtual space is used, a communication line in a place not registered in the specific server as a multiplayer virtual space is used. Even if the data managed by the computer connected to is displayed on the data display device, the data cannot be used as data for the multiplayer virtual space.

For the above reasons, when data held by a computer connected to a communication line can be referred to, most of the data is in an anonymous state in which the information of other viewers is unknown.

On the other hand, data display software such as Netscape Communicator or Internet Explorer checks the type of data and activates application software suitable for handling the data format, thereby making it possible to refer to various types of data. . At this time, since the data display software does not directly operate inside the data, Java
Even if a programming language represented by Script is used, it is not possible to describe a program for executing a predetermined operation using a state inside data as a trigger.

An object of the present invention is to enable information on a user who uses a virtual space to be freely displayed at an appropriate position in the virtual space.

[0011]

According to the present invention, user information to be combined and displayed is received from a communication line as needed. Also, it receives reference data from a computer connected to the communication line. From the file type of the reference data, the identifier of the data name, and the information embedded in the data itself, it is determined whether the content should be displayed as a three-dimensional virtual space or the data to be displayed two-dimensionally, and the data of the reference data is determined. The display form of the symbol representing the user information is determined so as to match the format. When the display mode is determined, the symbol representing the user information is displayed at an appropriate position on the screen in consideration of the order and depth relationship with the reference data.

As a result, the symbol representing the user information is displayed by being combined with the reference data. The display mode of the user information can be changed so as to be compatible with the data format of the reference data, and the display can be made by combining them. Necessary data can be acquired via a communication line using the internal state of the data to be synthesized as a trigger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described below.

FIG. 1 shows an embodiment of a three-dimensional virtual space system according to the present invention. In the figure, reference numeral 1 denotes a network, 2 denotes a virtual space management server, 3-i denotes a data server,
4-i indicates a data synthesizing display device.

The virtual space management server 2 receives the identifier of the user, the identifier of the virtual world in which the user participates, the position information of the user, the size of the virtual space in which the user participates, the input device represented by a mouse, and the like. And manages user operations on the virtual space.

The data describing the virtual world itself is not managed by the management server 2, but is managed by a computer (data server 3-i) connected to the network 1. The data is not stored in a computer (in the case of the figure, the data synthesizing display device 4-i) operated by all users participating in the virtual space, but when a request for participation occurs in the virtual space represented by the data. The data is transferred from the data server 3-i holding the data to the data synthesizing and displaying device 4-i requesting participation.

The data synthesizing and displaying device 4-i of each user includes:
The position information of the user is obtained from the data and the virtual space management server 2. A virtual object representing a user's alter ego is displayed at a specific position using the position information. When the user moves in the virtual space, the virtual object also moves in a direction and a distance corresponding to the moving operation.

A user operates on an object in the virtual world, and the object is designed to respond to the operation;
If the operation is designed to affect other users, a message indicating that the operation has occurred is transmitted to the virtual space management server 2. Using the identifier of the user and the identifier of the virtual world in which the user participates, the transferred message is transmitted from the virtual space management server 2 to the data synthesizing and displaying device 4- operated by the user affected by the operation. The message is transmitted to i.

According to the above procedure, it becomes possible for a large number of people to participate in the virtual space held by the computer connected to the network 1.

Since the virtual space management server 2 does not manage, for example, data describing the virtual space, the builder of the virtual world can restrict the number and scale of the virtual world to be constructed due to the performances of the virtual space management device. There is no restriction to suspend the use of virtual world users. Therefore, the creator of the virtual world can easily register new virtual world data or modify it. In addition, the virtual space display device can display a virtual space that is not registered in the virtual space management device as a place for multi-person communication.

In the present invention, the data synthesizing and displaying device 4-
i is the direct subject of the invention.

FIG. 2 shows a display processing flow of the data synthesizing display device. Step (S1): In the present invention, YES is used when the combined data definition file is used, and NO when not used. The data definition file contains
An identifier (URL) indicating a location on the network where each piece of data exists is described. Data synthesis display device 4-
i reads the identifiers in the order described in the file and performs display processing. The data read later is displayed in combination with the data displayed earlier, and the context is displayed earlier in the data read later. Step (S2): If YES, read the definition file. Step (S3): Required data is obtained. Step (S4): Determine the data format and determine whether it is two-dimensional data or three-dimensional data. The method of determination will be described later. Step (S5): Display processing is performed on the three-dimensional data. Step (S6): Display processing is performed on the two-dimensional data. Step (S7): Coordinate conversion is performed. Step (S8): It is checked whether or not it is necessary to obtain the synthesized data. If YES, the process returns to step (S3). Step (S9): Acquire user information. Step (S10): Display user information.

FIG. 3 shows a processing flow for displaying a virtual space in the data synthesizing and displaying apparatus. Step (S11): The user specifies a virtual space name. Step (S12): A virtual space is displayed. Step (S13): Enter a steady state with the virtual space displayed. Step (S14): Then, end processing is performed.

The process in FIG. 2 is considered to correspond to the process of combining two-dimensional data and three-dimensional data as necessary when displaying the virtual space in FIG. May be.

The format of the acquired data is determined, and is displayed in a format suitable for the information represented by the data. If a description of data that needs to be synthesized and displayed at the time of data interpretation for this display is included, newly specified data is obtained from the computer connected to the communication line, and the data format is determined. The composite display is performed in a format suitable for the format of the data already displayed. Finally, the user information is acquired, and the user information is displayed at an appropriate position on the screen according to the dimension of the data finally synthesized and displayed.

FIG. 4 shows an example of a screen on which a symbol of user information is synthesized and displayed according to the data format when the data format specified by the user for data display is two-dimensional information.

In the figure, reference numeral 21 denotes an image, a text or the like.
A screen at the time of displaying the dimensional information is shown, and reference numeral 22 denotes a caution position symbol indicating a position at which a user who refers to the information in the screen 21 draws attention.

Data referred by the user includes images, documents,
This is two-dimensional information represented by a moving image, and is displayed. The data synthesizing display device determines that the data format is two-dimensional data from the file type, the identifier of the data name, and the information embedded in the data itself (for example, two-dimensional information for AAA.html, BBB. If it is vrml, it can be determined as three-dimensional information).

Further, the information on the screen of the input device represented by the mouse is transmitted to the computer of the user who refers to the same data as the user information as the information being watched by the user. The own computer also receives the same user information from the computers of a plurality of users who refer to the same data. A symbol of the user in a two-dimensional shape is displayed at a position on the screen held by the received user information, together with the identifier of the user, so as to conform to the data format of the determined reference data.

FIG. 5 shows an example of a screen in which, when the data format specified by the user for data display is three-dimensional information, a symbol of the user information is synthesized and displayed according to the data format. In the figure, reference numeral 31 denotes a screen in a three-dimensional virtual space, and reference numeral 32 denotes a symbol of user information indicating a viewpoint position in a virtual space of a user who refers to information in the screen 31.

The data referred by the user is virtual space data described for displaying a three-dimensional virtual space.

The own computer also receives the same user information from the computers of a plurality of users who refer to the same data. A symbol of the user in a three-dimensional shape is displayed at a position on the screen held by the received user information, together with the identifier of the user, so as to conform to the data format of the determined reference data.

FIG. 6 shows an example of a combined display screen in which two-dimensional data and three-dimensional data are combined. In the figure, reference numeral 41 denotes a screen at a certain moment of a moving image, 42 denotes a three-dimensional virtual space created by imitating the arrangement of objects in the moving image, 43 denotes a screen when combined and displayed, and 44 denotes the screen 43. It is a caution position symbol indicating a position that draws the user's attention.

It is assumed that the data referred to by the user is two-dimensional information having depth information represented by an image and a moving image, and is displayed. The data synthesizing and displaying device determines that the data format is two-dimensional data from the identifier of the data name and information embedded in the data itself. It is assumed that the two-dimensional data is described so as to be synthesized with three-dimensional space data. The designated three-dimensional space data is acquired from a computer connected to a communication line. It is assumed that the three-dimensional space data is virtual space data created by imitating the arrangement of an object in the previously acquired two-dimensional data. The data format is determined to be three-dimensional data based on the identifier of the data name and information embedded in the data itself, and is synthesized and displayed at the designated position.

As the information that the user is watching, the viewpoint position of the user in the three-dimensional virtual space is transmitted to the computer of the user who refers to the same data as the user information. Also,
The own computer also receives similar user information from computers of a plurality of users who refer to the same data. At the position on the screen held by the received user information, along with the user identifier, the data format of the finally determined reference data conforms to the data format, and the depth relationship and the anteroposterior relationship with the already displayed data are appropriate. Thus, a symbol of the user in a three-dimensional shape is displayed.
