〔Example〕

FIG. 1 is a block diagram showing a hypermedia device according to the present invention. This device has a file storage unit 10,
Processing unit 20, display unit 30, mouse as pointing device
40 is connected to a common line 50. The file storage unit 10 stores a hypermedia file. The hypermedia file includes node data as a group of various information and link data as link information. The processing unit 20 performs reading and writing of the hypermedia file stored in the file storage unit 10, display processing of the display unit 30, and the like. The display unit 30 is, for example, a CRT display device, and displays various types of information processed by the processing unit 20 in node units. The mouse 40 is moved to a predetermined position of the information displayed on the display unit 30 and the mouse is moved.
A predetermined input is performed by clicking 40 mouse buttons. This device is also provided with a keyboard (not shown) for inputting predetermined information and commands.

FIG. 2 shows an example of a link relationship of the hypermedia files stored in the file storage unit 10. In FIG. 2, three nodes A, B and C are shown. The node A includes an object A-1 and an object A-2, the node B includes an object B-1, and the node C includes objects C-1 and C-2. Node A is linked to node B, and node B is linked to node C. Further, node A is linked to object B-1 of node B,
The object B-1 is linked to the node C and the object C-1 of the node C. The object A-1 of the node A is linked to the object B-1 of the node B, and the object B-1 of the node B is linked to the object C-1 of the node C. The object A-2 of the node A is linked to the node B. Further, the node B is linked to the object C-2 of the node C.

Looking at this relationship for node B, node A is the referenced node (reference source node) and node C is the reference node (reference destination node). The object C-2 of the node C is a reference object (reference destination object). Regarding the object B-1 of the node B, the node A is a referenced node (reference source node), the object A-1 of the node A is a referenced object (reference source object), and the node C is a reference node (reference destination). The node C and the object C-1 of the node C are reference objects (reference destination objects). Second
Table 1 shows the link relationships shown in the table.

Next, the operation of this embodiment will be described with reference to the flowcharts shown in FIGS.

Now, in a state where the node B is displayed on the display unit 30, the pointer 32 of the mouse 40 is moved to the link icon 31 of the node B as shown in FIG. 2, and a mouse button (not shown) of the mouse 40 is clicked. Suppose. First,
It is checked whether the link icon of the node is clicked (step 201). In this case, the link icon 3 of the node B is checked.
Since 1 is clicked, next, file storage unit 10
With reference to the hypermedia file stored in the node B, the clicked node, that is, the referenced link of the node B is followed to search for the reference source node and the reference source object (step 202). In this case, the reference source node is node A, and the reference source object is object A-2.
It is.

Next, referring to the hypermedia file stored in the file storage unit 10, the reference node of the clicked node, in this case, the node B, is followed to search for the reference destination node and the reference destination object (step 203). Here, the reference destination node is the node C, and the reference destination object is the object C-2.

Further, if the clicked node contains an object, the reference link of this object is followed to search for the reference source node and the reference source object (step 204). In this case, since the object B-1 is included in the node B, the node B refers to the hypermedia file stored in the file storage unit 10 and follows the reference link of the object B-1 to refer to the reference source node A and the reference node A. The original object A-1 is searched.

Next, an object included in the clicked node, in this case, the reference link of the object B-1 is followed to search for the reference destination node C and the reference destination object C-1 (step 205).

In this way, the source node, the source object,
When the search for the reference node and the reference object is completed, the reference node of the searched node, the reference object, the reference node, the reference object, the reference object of the object included in this node, the reference object, and the reference The destination node and the reference destination object are displayed as link menus at predetermined positions on the display unit 30 (step 206).

An example of the link menu when the link icon 31 of the node B is clicked by the mouse 40 is shown in FIG.

The link menu 301 shown in FIG. 5 indicates that the reference source node of the node B is the node A, the reference source object is the object A-2 of the node A, and the reference source node of the object B-1 is the node A and the node A. Object A-

If a reference destination object, for example, the icon 301-6 in FIG. 5 is clicked by the mouse 40 (step 213),
The node containing the reference object of the clicked node, in this case, node C is opened (step 214), and the reference source node of the menu-displayed object, for example, icon 301-3 in FIG. If so (step 215), the reference source node of the clicked object, in this case, node A is opened (step 216), and the reference source object of the object displayed in the menu, for example, the icon 301-4 in FIG.
Is clicked by the mouse 40 (step 21).
7) The node containing the reference source object of the clicked object, in this case, node A is opened (step 218), and the reference destination node of the menu displayed object, for example, the icon 301-7 in FIG. Is clicked (step 219), the reference node of the clicked object, in this case, node C is opened (step 220), and the reference object of the object displayed in the menu, for example, the icon 301- in FIG. If 8 is clicked by the mouse 40 (step 221), a node including the reference object of the clicked object, in this case, node C is opened (step 222), and each is displayed on the display unit 30 by a multi-window. You.

Next, the operation when the link icon 33 indicating the object B-1 is clicked by the mouse 40 while the node B is displayed on the display unit 30 will be described with reference to FIG. First, it is checked whether or not the link icon of the object has been clicked (step 231). In this case, since the link icon 31 of the object B-1 has been clicked, the hypermedia stored in the file storage unit 10 is next stored. With reference to the file, the clicked object, that is, the referenced link of the object B-1 is followed to search for the reference source node and the reference source object (step 232). In this case, the reference source node is node A, and the reference source object is object A-1.
It is.

Next, by referring to the hypermedia file stored in the file storage unit 10, the user clicks the reference link of the clicked object, in this case, the object B-1, to search for the reference destination node and the reference destination object (step 233). ). Here, the reference destination node is node C,
The reference destination object is the object C-1.

In this way, the source node, the source object,
When the search of the reference destination node and the reference destination object is completed, the searched reference source node, the reference source object,
The reference destination node and the reference destination object are displayed as link menus at predetermined positions on the display unit 30 (step 23).
