ABSTRACT:
BACKGROUNDS OF THE INVENTION
1. Field of the Invention
The present invention relates to a scenario edit device which edits a scenario for a multi-media application, and particularly, it relates to a scenario edit device capable of editing a scenario primarily by an intuitive operation.
2. Description of the Related Art
In a multi-media application, there is an application having a hyperlink structure which allows shifting from one screen to another one by a user's pressing a button on the display screen presenting image data, text data, sound data, button and the like, with a predetermined pointer. When editing a scenario of the application having such a hyperlink structure, edit for the screen shift processing is essential to decide which presentation screen to be selected by which press of a button.
As a conventional tool for editing a scenario having a hyperlink structure, there are a “ToolBook” disclosed in the article “ToolBook User's Manual” (issued by Asymetrix, 1994) and a “HyperCard” disclosed in the article “The HyperCard” (issued by B.N.S. Inc. on Mar. 31, 1988).
FIG. 23
is a block diagram showing an example of a constitution of a portion relative to the screen shift edit according to the conventional scenario edit tool such as the “ToolBook” or “HyperCard”. As illustrated in
FIG. 23
, the conventional scenario edit device comprises a scenario storage unit
2305
for storing a scenario for a multi-media application including the presentation screen shift, an edit image creating unit
2306
creating an edit image including the presentation screen designated by the scenario, an image display unit
2307
for displaying the edit image created by the edit image creating unit
2306
, an input control unit
2301
controlling input signal from an input device such as a mouse, a keyboard or the like, and preserving information of the position of a pointing cursor and the key stroke, a script edit unit
2302
editing a script described in the scenario on the basis of the information from the input control unit
2301
, a screen shift attribute changing unit
2303
changing a screen shift attribute described in the scenario on the basis of the information from the input control unit
2301
, and a presentation screen switching unit
2304
switching the presentation screen included in the edit image which the edit image creating unit
2306
creates on the basis of the information from the input control unit
2301
.
FIG. 24
is a view showing an example of components of the scenario information stored by the scenario storage unit
2305
. The scenario information indicated in
FIG. 24
includes the information such as the name of a presentation screen, a script corresponding to the presentation screen, a multi-media data name to be presented on the presentation screen, the presentation screen name of a link destination and the condition of a screen shift.
FIG. 25
is a view, which is created by the edit image creating unit
2306
, for use in describing one example of the edit image displayed by the image display unit
2307
.
FIG. 26
is a view for use in describing one example of the edit screen in the case of editing a script by the script edit unit
2302
.
FIG. 27
is a view for use in describing one example of the edit screen in the case of editing the screen attribute by the screen shift attribute changing unit
2303
.
A movement in the screen shift edit by the use of the above conventional scenario edit device will be described in
FIGS. 23
to
27
.
Assume that the scenario indicated in
FIG. 24
is stored in the scenario storage unit
2305
. An operation of editing the screen shift toward the presentation screen “SCENE_
3
” by the operation toward the multi-media data “BUTTON_
22
” on the presentation screen “SCENE_
2
” will be as follows.
The display image switching unit
2304
, upon receipt of the instruction “Start the edit of the presentation screen “SCENE_
2
”” from the information preserved in the input control unit
2301
, instructs the edit image creating unit
2306
to create the edit image of the presentation screen “SCENE_
2
”. The edit image creating unit
2306
creates the edit image including the presentation screen “SCENE_
2
” as illustrated in FIG.
25
. The image display unit
2307
displays the created edit image. The script edit unit
2302
, upon receipt of the instruction “Start the script edit of the presentation screen presented in the edit image being displayed on the image display unit
2307
” from the information preserved in the input control unit
2301
, starts the script edit (refer to
FIG. 26
) of the presentation screen “SCENE_
2
”. The edit of the script characters enables the screen shift edit into the presentation screen “SCENE_
3
” by the operation toward the multi-media data “BUTTON_
22
” presented on the presentation screen “SCENE_
2
”.
An edit operation, according to the above conventional scenario edit device, for shifting the screen to the presentation screen “SCENE_
6
” by the operation toward the multi-media data “BUTTON_
13
” presented on the presentation screen “SCENE_
1
” will be as follows.
The presentation screen switching unit
2304
, upon receipt of the instruction “Start the edit of the presentation screen “SCENE_
1
”” from the information preserved in the input control unit
2301
, instructs the edit image creating unit
2306
to create the edit image of the presentation screen “SCENE_
1
”. The edit image creating unit
2306
creates the edit image including the presentation screen “SCENE_
1
”. The image display unit
2307
displays the created edit image. The screen shift attribute changing unit
2303
, upon receipt of the instruction “Start the edit of the screen shift attribute of the multi-media data presented in the edit image being displayed on the image display unit
2307
” from the information preserved in the input control unit
2301
, edits the dialogue box for the screen shift attribute as for the multi-media data “BUTTON_
13
” (refer to FIG.
27
), and selectively determines the presentation screen to which this screen is shifted and the condition of the screen shift. This enables the screen shift edit into the presentation screen “SCENE_
6
” by the operation toward the multi-media data “BUTTON_
13
” presented on the presentation screen “SCENE_
1
”.
The conventional scenario edit device, however, requires the edit of a script language, the selection of the presentation screen name of a shift destination as the attribute of each multi-media data and the input of the same, as mentioned above. Owing to this, it is necessary for an editor to have a fair knowledge of the script language and memorize the presentation screen name of a shift destination, which results in a great burden to the editor.
Further, it is impossible for the conventional scenario edit device to do such a visual and intuitive edit work as to discriminate a presentation screen and a screen shift processing at a glance, create the screen shift processing, change the screen of a shift destination and delete the screen shift processing, thereby resulting in a poor working efficiency.
SUMMARY OF THE INVENTION
A first object of the present invention is to provide a scenario edit device in which, on the edit screen for editing a scenario for a multi-media application, presentation screens presented at execution of the application are made into icons and the relation of the screen shift between the presentation screens is expressed by an arrow or the like so that a hyperlink structure can be viewed at a glance and a scenario editor can understand the structure of the scenario visually and intuitively, thereby improving the working efficiency of the edit work.
A second object of the present invention is to provide a scenario edit device capable of editing a scenario about the screen shift by such an intuitive operation as to create the screen shift operation with an arrow drawn between icons of the presentation screens, change a shift destination and a shift source while changing an arrow and delete the screen shift operation by deleting an
