The only difference is that the branch will not appear as a line with a circle but instead as a two way arrow as shown in Figure 7.
  • Orphans are screens that have lost their parents either by having had the parent screen deleted or the branch from the parent screen deleted. An orphan can still have child screens and those child screens can have child screens. In other words it is possible, by deleting a parent or branch, to disconnect a whole segment of your presentation from the rest of the presentation, leaving no way for the user to actually branch there.

All editing commands can cause orphans. As discussed below, this is actually a powerful and easy way to rearrange the hierarchy of the presentation.
  • Dragging the screen tool into a hot spot that already has a branch will create a panel to appear alerting the author that a branch exists and asking the author if he or she would like to insert a new screen. Choosing yes will cause the new screen to be inserted between the parent and existing child screen.

There can be more than one template windows per presentation document. Templates are screens where all the graphics and media are "locked. " A template is created in the simulator when it was in template edit mode. Any asset put into the simulator in template edit mode will be part of the template including hot spots and sounds.

  • An alert panel will give the author the option of connecting the template to (1) screen only, (2) screen and all children, or (3) screen and children in the same column as screen.
  • Templates can be duplicated and deleted. Duplicating a template makes a copy of the selected template and adds it to the template window with a slightly different name. It can then be edited to make it slightly different or whatever is desired. Deleting a template raises an alert panel in the event the template being deleted is connected to any screens in the navigator. Clicking OK deletes the template from the application and the template window. Contents of the navigator can be printed out on multiple sheets. If the navigator contents printout extends over multiple sheets, these sheets may be taped together. This is a useful tool frequently used by designers of interactive media in conceptualizing their product, similar to the manner in which story boards are employed by animators and film directors.
  • Navigating is accomplished as follows. Clicking on a screen in the navigator brings that screen up in the simulator. Clicking on a line/circle space non-linear branch representation jumps to that screen in the navigator and causes it to appear in the simulator. Vertical and horizontal scrollers allow the author to move to any spot in the navigator.

Authoring Process Example
  • the tool panel 20 appear.
  • the presentation selection 62 on the main menu 25 is selected and a new presentation from the presentation menu is selected. This will cause a blank simulator screen 18 to appear.
  • the template button 64 is clicked at the bottom of the simulator. This causes the system to enter the edit template mode.
  • the template button will turn white to indicate that a template is being edited and not an ordinary screen.
  • a template is used for graphics, sounds, and other media that are to be common to every screen in the presentation. A simple example would be a background color.
  • the "create one" button in the middle of the simulator window (not show) is clicked and the image tool 28 is dragged from the tool panel to the simulator as shown in Figure 19. This will cause an open panel file finder to appear (not shown) to allow the selection of a particular desired template.
  • the hot spot tool 36 is then dragged into the lower right comer of the simulator as shown in Figure 20. As shown in Figure 21, the sizing handles can be used to expand the hot spot to cover the entire lower right comer of the simulator.
  • the tools menu 27 in the main menu 25 is then selected and the screen navigator command 46 is then selected to cause the screen navigator to appear as shown in Figure 22.
  • the snapshot of the screen from the screen navigator is then dragged to the hot spot in the simulator and dropped into the hot spot. This creates a branch to the main screen (i.e., screen one) that will be present in all screens (since the system is in the template mode).
  • the template button is clicked again to exit template edit mode.
  • the first screen will be created with text and two hot spots.
  • One hot spot will lead to a sound samples the text, the text tool 32 is dragged into the simulator.
  • the word text appears surrounded by sizing handles to permit enlarging the text area.
  • the word "text” is double clicked and the desired text is typed over it. For example, "this is a demonstration of an interactive media presentation.”
  • the font menu may be selected to permit a particular font to be chosen for the text.
  • the text color can be selected by selecting the tool menu 27 in the main menu and clicking on the colors command to cause a color panel to appear as shown in Figure 24.
  • Future hot spots can be labeled by dragging the text tool 32 into the simulator, which causes the word text to appear surrounded by sizing handles. Double clicking the word “text” and typing the following over it "click here for sounds”, and repeating the steps and typing "click here for images", is performed next. Then the hot spot tool 36 from the tool panel is dropped over the text "click here for sounds” as well as the text "click here for images.” The screen tool 42 from the tool panel is dropped into one of the hot spots and then dropped into one of the other hot spots. The navigator will automatically display these new screens. Next, the screen in column A, row 2 of the navigator is clicked “on” and the text tool is dragged into the simulator and dropped over the hot spot. The word "text” is double clicked and
  • the text tool is dragged on top of each button and they are labeled "bell”, "click”, and “crowd.”
  • the hot spot tool is then dragged over each button to resize the hot spots to fit the buttons.
  • the sound tool 34 is dragged from the tool panel and dropped anywhere in the simulator window. This causes the open panel to come up which permits the selection of the "bell” sound from a sounds directory.
  • the user control drags from the button labeled "bell” to die sound icon in the lower left comer of the simulator shelf 26. When it connects, the sound icon is surrounded by a gray border. See Figure 27.
  • the screen in column B, row 2 of the navigator (see Figure 29) is dragged into the simulator. This causes the open panel to come up and the button image is selected from the icons directory. This step is repeated until two buttons are in the simulator. Text is placed on the button so they are labeled "flowers" and "beach.”
  • a hot spot tool is dragged and dropped over each button and they are resized to fit the buttons.
  • the screen tool 42 is then dragged and dropped onto the hot spot labeled "flowers" which creates a new screen that appears in column B, row 3 of the navigator as shown in Figure 29.
  • the image tool is then dragged from the tool panel into the simulator and the "petunias" file is selected from the images directory.
  • the timer tool is dragged from the tool panel and dropped anywhere on the simulator.
  • the snapshot of the screen in column B, row 2 of the navigator is then dragged into the timer in the simulator.
  • the tools menu 27 is selected and the inspector.
  • Clicking on the play button 68 at the bottom of the simulator will result in a delay of five seconds (as set in the timer) after which the screen should change to the screen with the flower and the beach buttons.
  • the presentation can also be tested by clicking on each of the "click here" messages as described above.
  • the resulting screen navigator shown in Figure 30, thus provides an easy to read overview of the screens just created.

  • NeXTSTEPTM 3.0 now available on 486-based PCs
  • Callisto incorporates all the advanced features of NeXTSTEPTM 3.0 (now available on 486-based PCs), allowing you to use Callisto with other standard NeXT graphics, paint, image processing, and audio applications.
  • Novell Netware® and AppleTalk® support from NeXTSTEP Callisto can even accept files from your favorite PC and Macintosh applications.
  • This guide is designed for those somewhat familiar with both the NeXTSTEP environment and with the technologies used to create the media assets (e.g., image, movie, or sound files) used in Callisto.
  • media assets e.g., image, movie, or sound files
  • This guide contains a chapter describing the basics concepts and procedures used in Callisto, a chapter about each Callisto tool, a glossary of terms, and an index.
  • the topics addressed in each chapter are described below:
  • Control-drag means to hold down the Control key while dragging the mouse.
  • Callisto is self- contained and needs no other software in order to run. It does require, however, that you have either the media assets you want to include in your presentations (for example, image files stored in .tiff or .eps format) or the means to produce them.
  • a Callisto presentation is made up of a series of screens, each of which is created in a window called the Simulator.
  • Each screen may contain one or more of these media elements: images movies text sound hotspots timers paths graphics
  • Assets can also be grouped; for example, you may want to ensure that a specific image and its accompanying text always go together. Once assets are grouped, the group behaves just like any other single asset.
  • a screen may have a template attached to it.
  • a template consists of one or more assets that you wish to be common among all or a selected group of screens. For example, templates are commonly used to assign a background color or pattern to a set of related screens. For more information about templates, see chapter 8, The Template Navigator.
  • Assets fall into two distinct types: those you can see and those you can't. Images, movies, text, graphics, and hotspots will be visible when you play a presentation, but sound, timers, and paths won't be.
  • Assets that you can see are called spatial (since they take up space on a screen), and assets that you can't see are called non- spatial.
  • spatial assets are added to a screen, they are visible in the Simulator's Display Area (the upper part of the window).
  • non-spatial assets are added to a screen, they are represented by an icon in the Icon Shelf (the lower part of the window).
  • Callisto accepts the following file formats:
  • the remaining assets are created in Callisto and do not have associated source files.
  • Hotspot and Timer tools are key to making a presentation work. Hotspots and timers send action commands to screens and their assets. In turn, action commands determine how screens and their assets function during a playing presentation.
  • Hotspots and timers share the same basic function, the only difference being that hotspots send action commands in response to a mouse event and timers send action commands after a specified amount of time has elapsed (you don't have to do anything to make the action occur).
  • Branch command is the only action command that is not sent to an asset, but is instead used to open another screen.
  • Branch command is the only action command that is not sent to an asset, but is instead used to open another screen.
  • Show, Hide, and Branch action commands can have visual effects attached with them that determine how a transition looks on the screen. By default, no visual effects are attached to an action command, however you can choose to add one of the following effects:
  • Hotspots can have different responses (i.e., send different action commands to an asset) based upon the type of mouse event that occurs within the bounds of the hotspot:
  • the hotspot is connected to a sound
  • the Main menu and all of its submenus contain all the commands you'll need to use Callisto. You can either use the mouse to select commands from a menu or, in many cases, use a command key to execute them without opening a menu.
  • the Tool Panel is used to add assets to your screens, and to add screens to your presentation. In most cases, assets are added to a screen by dragging them with the mouse from the Tool Panel into the Simulator.
  • the Screen Navigator automatically creates a graphic "outline" of your presentation as you build it, giving you a quick and easy way to see the whole presentation at a glance or to move instantly to any screen.
  • the Screen Navigator Connecting arrows show you how the screens branch to and from one another.
  • Templates are assets that you wish to be common among all or a selected group of screens (a background color or pattern, for example).
  • the Template Navigator displays all of the templates in a Callisto presentation. Use the Template Navigator to select a template to edit or to attach a template to a screen.
  • the Inspector is used to examine and make changes to a screen and the assets it contains.
  • the Inspector automatically displays the parameters and settings of the currently selected item in the Simulator. Changing the selection within the Simulator will change the contents of the Inspector.
  • the Colors panel used in most NeXTSTEP applications, is used to add color to text, hotspot, and graphic assets. Using the panel, you can use the mouse to "drag color" from the panel into an asset on a Callisto screen. You can also choose among several methods for mixing color, select PANTONE® colors, and create custom color palettes.
  • the Sound Record panel lets you add sound to a screen without an .snd file. Use the microphone on your workstation along with this panel to record, stop, playback, pause, and erase sound. Using the Sound Tool icon on the panel, you can drag the recorded sound directly into your presentation.
  • This section covers basic operations such as creating and opening presentations, adding assets, and saving and closing presentations.
  • the Tool Panel consists of two sections:
  • spatial assets images, movies, text, hotspots, and graphics
  • Non-spatial assets are represented by an icon in the Icon Shelf.
  • the Graphics palette is used to create freehand graphics in the screen or template shown in the Simulator.
  • Any spatial asset (image, movie, text, hotspot, graphic) or group can be moved using the mouse. Move the cursor over the asset, press the mouse button, and drag the asset to its new location.
  • Any spatial asset on a screen can be resized using the mouse.
  • Deleting any asset not only removes it from the screen, but also deletes its connections to other assets. For example, if you delete a path, the assets connected to that path remain on the screen but their connections to the path are severed. The same rule applies to hotspots and timers.
  • Selected assets on your screen can be cut or copied into a buffer (the "pasteboard") and then pasted into a new location on either the current screen or into another screen.
  • Hotspots and timers can be cut and pasted, but not copied.
  • the Align and Grid commands on Callisto ' s Layout menu are used to refine how your assets are positioned on the screen. These commands apply only to spatial assets appearing in the Simulator's Display Area; if an icon in the Icon Shelf is selected, the Align and Grid commands are disabled.
  • the Align command is used to align spatial assets in a variety of ways relative to their
  • the Text Baseline button applies only to a set of selected text assets. Use this button to set a common baseline for text assets regardless of their font or point size.
  • the four Distribute buttons are used to evenly distribute horizontal or venical spacing among assets based on either their center points or the gap between their edges. Three or more assets are needed to enable the Distribute buttons.
  • the Grid button is used to go directly to the Grid panel without having to select it from the Layout menu.
  • the Grid command is used to control the existence and appearance of a grid with which you can refine the alignment of size of your assets.
  • the Grid Visible box determines whether or not a grid is displayed in the Simulator's Display Area.
  • the Size to Grid and Align to Grid buttons are enabled only if the Snap to Grid box is checked. Use these buttons to adjust the size and/or alignment of selected assets based on their proximity to the grid.
  • the Align button is used to go directly to the Align panel without having to select it from the Lavout menu.
  • Assets are "layered,” meaning that each new asset added to the screen is added "on top of” any existing assets. Assets have an inherent layering order whether or not they visually overlap on the screen.. You can move assets backward and forward through the layers with the various commands in the Layout menu.
  • Groups have their own Inspector panel, and perform like any other spatial asset. Groups can be connected to a path, timer or hotspot, and can be either shown or hidden when a screen is opened in Play mode.
  • An asset's connections to paths, timers, or hotspots do not automatically carry over when it becomes part of a group. Groups need to have their own connections defined.
  • One or more assets must be selected in order to use the Lock command. Selected assets must also be spatial; paths, sounds, and timers cannot be locked.
  • Locking an asset protects it from being repositioned or altered, but does not lock its connections to other assets. For example, if locked text is connected to a path, the path can still be deleted, and with it, the text ' s connection to it.
  • Unlock command Use the Unlock command to revert your assets back to an editable state. Because individual assets can't be selected when they are locked, the Unlock command unlocks all locked assets in a screen.
  • Your presentation is automatically saved before the play-only version is generated. This prevents any unsaved changes from being included in a play-only version and then lost if the version is later resaved as editable.
  • the Windows menu also notes whether a given presentation is in Edit or Play mode, and whether changes have been made since it was last saved.
  • Printing Presentation Screens Use the Print command to print out a copy of a presentation screen. Use the three options in the Simulator Print Option group to determine what gets printed:
  • the Performance button prints your Content or Window selection in Play mode (no hotspots are visible).
  • the Format menu's Page Layout command is used to change the layout of your printed screens.
  • Width/Height the size of the paper as defined by the Units selection; if you want a paper size not available from the pop-up menu, enter the size values here.
  • Callisto's menu structure provides all the commands you'll need to build and refine your presentations.
  • the Main menu appears automatically when you open Callisto. All other submenus are opened from the Main menu.
  • Command keys are case sensitive: for example, the uppercase "V" after the Paste Under command means to press Command-Shift-V, while the lowercase “v” after the Paste command means to press Command-v, without the Shift key.
  • Info opens the Information menu, from which you can access release data for Callisto, set usage preferences, and obtain online help.
  • Presentation opens the Presentation menu used to create, save, and close Callisto presentations.
  • Edit opens the Edit menu used to cut, copy, and paste screens and assets, check the spelling of text, and add new templates.

  • Info Panel displays release information about Callisto.
  • Open brings up the Open panel used to open an existing presentation.
  • New brings up the New panel used to create a new presentation.
  • Cut removes the selected screen or asset from the Simulator or Screen Navigator and places it in a memory buffer so that you can move it from one place to another.
  • Paste inserts the contents of the memory buffer at the cursor location.
  • Paste Under is used only with the Screen Navigator, and pastes cut or copied screens as children of a selected screen.
  • Add Template adds a new template to the template Navigator.
  • Spelling opens the Spelling panel used to manage the contents of the online dictionary; if a text string is selected, use this panel to search the dictionary for similarly spelled words.

  • the Simulator has three main components:
  • the Display Area is the upper part of the Simulator window where spatial assets are displayed and edited. It operates much like a drawing program in that you can draw freehand graphics; add and edit text; and move, cut, copy, and paste a screen's assets. When you add assets to a screen by dragging a tool icon from the Tool Panel, you drop it inside the Display Area.
  • the Size Bar directly beneath the Display Area is used to change the screen size either horizontally, vertically, or both.
  • the current screen width and height (in pixels) is displayed in the Simulator's title bar.
  • the Edit and Play radio buttons let you alternate between Edit and Play mode. Use Edit mode to add screens and assets to a presentation, and use Play mode to test it to ensure that the presentation operates correctly.
  • the Simulator's title bar will say "Editing” when in Edit mode, and "Playing” when in Play mode.
  • the Width and Height fields allow you to change the horizontal and vertical dimensions of the screen. Using these fields, you can set the exact size (in pixels)of the
  • Resizing a screen does not resize the assets contained within it. In addition, resizing adjusts screen size from the top and right only. If you make a screen smaller, assets at the very top and right of a screen may shift out of view; if you make a screen larger, extra space appears at the top and right.
  • a template consists of one or more assets that may be shared among screens. Templates may consist of images, hotspots, timers, sounds, or any asset that you want several screens to have in common. Any asset you put into the Display Area while in Edit Template mode becomes part of the template, and will appear as an unselectable asset while in Edit mode for the screen.
  • the Icon Shelf appears at the bottom on the window, and displays icons representing the non-spatial assets (sounds, timers, and paths) in a screen. To make connections between spatial and non-spatial assets, drag the mouse between the assets in the Display Area and those in the Icon Shelf.
  • Each row of the Icon Shelf holds ten icons; if you add more than that, scroll bars appear so that you can scroll through the shelf. Or, you can use the size bars at the bottom of the Simulator window to increase the size of the Icon Shelf.
  • Notched icons represent assets that are part of the screen's template. These kinds of assets can only be modified in Edit Template mode.
  • a notched icon indicates an asset that is part of a template
  • Callisto Tool Panel Use the Callisto Tool Panel to add assets and screens to your presentation. Callisto offers the following tools:
  • Hotspots and timers are used to control the display of the other assets; in other words, they make your presentation run. Hotspots perform actions (such as branching to a new screen) when a user clicks on them; timers perform the same actions actions based upon how much time has elapsed.
  • Image files may be in either .tiff or .eps format.
  • the Image Inspector displays detailed information about a selected image. Use the Image Inspector to:
  • Movies may be in either .mw or .anim format.
  • a movie begins to play as soon as the screen opens in Play mode. You can change that default by changing the settings in the movie's Inspector panel and then connecting the movie to a hotspot or timer. See Connecting a Movie to a Hotspot or Timer for details.
  • Movies can also be dragged into the Display Area from the NeXT File Viewer.
  • the folder can now be added to your screen the same way as with any other movie: either drag the folder from the NeXT File Viewer into the Simulator's Display Area, or drag-drop the movie icon from the Tool Panel into the Display Area and select the folder you just created from the Open panel.
  • the movie is played, Callisto cycles through the images in the order they were placed in the folder.
  • the Movie Inspector provides detailed information about a selected movie. With the Movie Inspector you can:
  • Text from other applications can be added to a Callisto screen only if the text is saved in TIFF or EPS format and included as an image asset.
  • Paste Font applies the previously copied font type and point size to selected text.
  • Font and Text menu commands affect only the text comprising a single asset; they are not used to align multiple text assets with one another. Aligning multiple assets (regardless of type) is accomplished using the Layout menu's Align command.
  • Sizing the text field does not change the size of the text itself, but only the amount of space surrounding it.
  • a text asset's font and point size are changed only by using the options on the Format menu's Font panel.
  • the Spelling command opens the Spelling panel used to manage the contents of one or more online dictionaries. Initially, the Spelling panel manages the online dictionary provided by NeXT. If you've installed other dictionaries, you can use this panel to manage them as well.
  • Text doesn't have to be selected to open the Spelling panel, but if it is (in other words, if you've double-clicked on a text
  • Dictionary menu this button opens a menu of all installed online dictionaries from which you can make a selection.
  • Forget use this button to delete a word you've previously added to a dictionary.
  • Entry Field if no text is selected, you can use this field to type in a word whose spelling you want to query, and then click Guess.
  • List Box lists words similar to the selected word. If one of them is the word you want, either select it from the list and click Correct or double-click it on the list.
  • Find Next locates the next misspelled word in the selection.
  • the Check Spelling command checks the online dictionary to see if it contains a word that matches selected text. This command does not open the Spelling panel. To enable this command, double-click within the text to highlight the text string(s) you want to check.
  • Text is commonly used to label hotspots, since the hotspot' s border isn't displayed when a screen is in Play mode. Placing text over a hotspot (the words "click here," for example) is one way of telling the user where to click to initiate some other action.
  • Hotspot Connecting Text to a Hotspot or Timer Connect a timer or hotspot to your text if you want it to appear or disappear only after a certain amount of time has elapsed or when a hotspotdetects a given mouse event. For example, you could create a screen with two text assets: a question and an answer. Using a hotspot, you could set the answer to be hidden
  • the answer could appear automatically after a given amount of time had elapsed.
  • a sound will occur automatically when a screen is opened. Connect sound to a hotspot or timer if you want it to start only after a certain amount of time has elapsed or when a hotspot detects a given mouse event.
  • the Sound Inspector displays detailed information about the sound file, such as how long it plays and how many times it repeats (loops).
  • the panel also contains a graphic representation of the sound so that you can cut and paste sound segments. Use the Sound Inspector to:
  • Hotspot tool to add interactive capability to your media presentation.
  • an action command is sent to whatever assets the hotspot is connected to.
  • the hotspot may direct the presentation to branch to a new screen; start, stop, pause or resume sound; show or hide an image; and even activate another hotspot.
  • a hotspot may be connected to multiple assets, allowing it to send more than one action command at the same time (starting a movie and soundtrack together, for instance).
  • a hotspot performs the same functions as a timer, the only exception being that it performs them as a result of mouse events rather than elapsed time.
  • the Screen is not considered a media asset.
  • Branch command is somewhat unique in that it indicates a branch to another screen.
  • Hotspot Tool icon To add a hotspot, drag the Hotspot Tool icon from the Tool Panel and drop it on the screen where you want the hotspot to be.
  • the hotspot can overlap other assets (you can place a hotspot over an image or a text string, for example).
  • a thick line will outline the hotspot while the Simulator is in Edit mode, but will be invisible in Play mode.
  • Hotspots can be connected to all types of assets:
  • One hotspot can be connected to several different assets; for example, you can connect a hotspot to both a movie and sound to start them at the same time when the presentation is played.
  • the same hotspot has two connections to the same sound.
  • the sound begins playing when the screen opens. The first time you press the left button, the sound pauses, the sound resumes when you release it.
  • Timers with multiple connections to the same asset work much the same way, except that instead of each action happening after a given number of mouse clicks, each action occurs after a a predetermined amount of time.
  • the hotspot will be temporarily bordered in grey to show you that the connection is being made.
  • the Branch action command is automatically assigned to the connection between the hotspot and the screen.

  • a timer starts the moment a screen is opened in Play mode.
  • use the Time field in the Timer Inspector to enter the amount of time it takes before the timer's associated action command is sent to whatever asset it is linked to.
  • the Screen is not considered a media asset.
  • Branch command is somewhat unique in that it indicates a branch to another screen.
  • Timer Tool icon To add a timer, drag the Timer Tool icon from the Tool Panel and drop it into the Simulator's Display Area. A timer icon appears in the Icon Shelf.
  • Timers can be connected to all types of assets:
  • One timer can be connected to several different assets; for example, you can connect a timer to both a movie and sound to start them at the same time when the presentation is played.
  • the same timer has three unique connections to the same sound.
  • the sound begins playing when the screen opens.
  • the first timer then instructs the sound to pause after 5 seconds, the second timer resumes the sound after ten seconds, and the third timer stops the sound entirely.
  • Hotspots with multiple connections to the same asset work much the same way, except that instead of each action happening after a predetermined amount of time, each action occurs after a given mouse event.
  • the timer will be temporarily bordered in grey to show you that the connection is being made.
  • the Branch action command is automatically assigned to the timer.
  • Timer Actions with Visual Effects When a timer is used to display or hide an asset or a screen (in other words, when it has a Show, Hide, or Branch action assigned to it), you can use the Timer Inspector to select from a variety of visual effects:
  • the timer begins counting down as soon as the screen opens in Play mode. This default can be changed using the Time field in the Timer Inspector panel.
  • the Timer Inspector is used to edit time settings for a timer. Use the Timer Inspector to:

Abstract

Système et procédé de création de présentations multimédia interactives (14). Il s'agit d'un système de création rationalisé comprenant l'utilisation d'une interface d'utilisateur simplifiée qui rend plus aisées la production (20), la création de graphismes (20) et la mise à l'essai (24) de présentations multimédia interactives (14) au cours du procédé de création. Le système comprend l'utilisation d'un modèle intuitif (10) qui permet de produire des supports interactifs (16) plus rapidement et plus efficacement que les systèmes courants. Le système permet de créer et d'agencer de nouveaux attributs avantageux (12) des supports, ou des attributs préexistants de ces derniers en une séquence modifiable destinée à l'affichage interactif et à ramifications. Il comprend l'utilisation d'une fenêtre de simulation (18) dans laquelle des écrans individuels dans une présentation multimédia sont développés. Un procédé simplifié permettant d'établir des liaisons hiérarchiques entre ces écrans est également décrit. Un dispositif de navigation (22) génère et affiche automatiquement une représentation graphique de chaque écran en même temps qu'une représentation de sa position dans la hiérarchie d'écrans reliés tandis que les écrans et les liaisons sont générées. Ceci permet d'éviter la création manuelle d'organigrammes de présentation. En conséquence, la présente invention est extrêmement conviviale et ne requiert pas de connaissances étendues en matière de programmation de la part de l'utilisateur.
