Sent. Specifically, an arbitrary position in the 3D space is designated by the input device 22, and initial setting such as the title and explanation of the discussion, the display position, etc. is performed (S1).

  The 3D client module 30 receives the request at the discussion generation unit 38a of the discussion control unit 38, and the 3D space information processing unit 34 performs a process for adapting to the 3D space. Then, a request for reflecting the position and content of the generated discussion object in the 3D space is transmitted from the 3D space information processing unit 34 to the server application 12 via the communication unit 32 (S2).

The server application 12 updates the 3D spatial information stored in the database 10 to reflect the discussion object in the 3D space (S3), and converts the updated 3D spatial information into the format of each client terminal 2. The data is transmitted to the 3D client module 30 of each client terminal 2 (S4).
The 3D client module 30 of each client terminal 2 analyzes the 3D spatial information received via the communication unit 32 in the 3D spatial information processing unit 34 and displays it on the display 20 via the image generation unit 36 (S5).

  For specific operations, referring to FIGS. 3 to 6, an example of a 3D space image displayed on the display 20 of the client terminal 2 is shown. In each of the drawings, a building 50 such as a house is provided along a road 52 on a 3D space image, and a street lamp 56 is also provided on a sidewalk 54 between the road 52 and the building 50.

The 3D client module 30 requests the discussion information from the server application 12 in order to obtain information held by the designated discussion object (hereinafter also referred to as discussion information) (S11).
The server application 12 inquires the database 10 for discussion information designated in response to the received request (S12).

The database 10 searches the discussion information for which the inquiry has been received, and returns the corresponding discussion information to the server application 12 (S13).
The server application 12 transmits the discussion information that has received the response to the 3D client module 30 of the client terminal 2 that has received the request (S14).
The 3D client module 30 analyzes the information regarding the discussion object received via the communication unit 32 in the 3D space information processing unit 34 and displays the information on the display 20 via the image generation unit 36 (S15).

When the displayed discussion information is edited such as addition of a comment via the input device 22 (S20), the discussion editing unit 38b of the 3D client module 30 receives the edited content, and the 3D spatial information processing unit 34 The edited content of the discussion information is transmitted from the server to the server application 12 via the communication unit 32 (S21).
The server application 12 updates the discussion information stored in the database 10 so that the edited content is reflected in the discussion information (S22), and the 3D spatial information reflecting the editing of the discussion information is formatted in each client terminal 2. And converted to the 3D client module 30 of each client terminal 2 (S23).

The 3D client module 30 of each client terminal 2 analyzes the 3D spatial information after editing the discussion information received via the communication unit 32 in the 3D spatial information processing unit 34 and displays it on the display 20 via the image generation unit 36. (S5). Thereby, in each client terminal 2, the state after editing of discussion information can be confirmed.
