Description:
BACKGROUND 
     The present disclosure relates generally to electronic devices, and, more particularly to electronic devices with projected displays that may be linked to form a shared workspace. 
     This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. 
     One use which has been found for computers has been to facilitate the communication of information to an audience. For example, it is not uncommon for various types of public speaking, (such as lectures, seminars, classroom discussions, keynote addresses, and so forth), to be accompanied by computer generated presentations that emphasize or illustrate points being made by the speaker. For example, such presentations may include music, sound effects, images, videos, text passages, charts, diagrams, drawings, numeric examples or spreadsheets, or audiovisual content that emphasizes points being made by the speaker. 
     Typically, these presentations are composed of “slides” that are sequentially presented in a specified order. These slides may contain audiovisual content in the form of objects placed on the slides. One challenge that may face those who create such presentations are the complexities involved in creating and modifying the slides and objects used in a presentation and the association of effects with such slides and objects. 
     SUMMARY 
     A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below. 
     The present disclosure generally relates to a user interface that may be used to implement different types on animation in a slideshow presentation. For example, the user interface may be used to preview, review, add, and/or modify transition associated with moving from one slide to the next and object builds associated with moving or changing an object on a slide. In one embodiment, different aspects of the user interface may be provided in response to a user selecting an object or a slide for review or modification. For example, upon selecting a slide for review, a user interface may be displayed that is attached to or proximate to the selected slide or slide representation and which may then be navigated to create or modify the slide transition Likewise, upon selecting an object for review, a user interface may be displayed that is attached to or proximate to the selected object and which may then be navigated to create or modify a build associated with the object.

     The communication module facilitates communication with other devices over one or more external ports  34  and also includes various software components for handling data received by the RF circuitry  22  and/or the external port  34 . The external port  34  (e.g., Universal Serial Bus (USB), FireWire (IEEE 1394 High Speed Serial Bus), Ethernet port, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port  34  is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod® devices. 
     The contact/motion module may facilitate the detection and/or interpretation of contact with a touch sensitive input device, such as a touch screen, click wheel or touch pad. The contact/motion module includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). 
     The graphics module includes various known software components for rendering and displaying graphics on the display  12  or other connected displays or projectors, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user. In some embodiments, the graphics module stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphics module receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to the display controller  44 . 
     Examples of applications that may be stored in storage/memory  14  may include work productivity applications as well as other applications. Examples of such applications may include word processing applications, image editing applications, drawing applications, presentation applications, Java-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

As shown in  FIG. 2 , the electronic device  10  in the form of a laptop computer  60  includes a housing  62  that supports and protects interior components, such as processors, circuitry, and controllers, among others. The housing  62  also allows access to user input devices  32 , such as a keypad, touchpad, and buttons, that may be used to interact with the laptop computer  60 . For example, the user input devices  32  may be manipulated by a user to operate a GUI and/or applications running on the laptop computer  60 . 
     The electronic device  10  in the form of the laptop computer  60  also may include various external ports  34  that allow connection of the laptop computer  60  to various external devices, such as a power source, printer, network, or other electronic device. For example, the laptop computer  60  may be connected to an external projector through a cable connected to a respective external port  34  of the laptop computer  60 . 
     In addition to computers, such as the depicted laptop computer  60  of  FIG. 2 , an electronic device  10  may take other forms, such as a portable multi-function device  70  (such as a cellular telephone or a tablet computing device) as depicted in  FIG. 3 . It should be noted that while the depicted multi-function device  70  is provided in the context of a tablet computing device, other types of portable or handheld devices (such as cellular telephones, media players for playing music and/or video, a camera or video recorder, personal data organizers, handheld game platforms, and/or combinations of such devices) may also be suitably provided as the electronic device  10 . Further, a suitable multi-function device  70  may incorporate the functionality of more than one of these types of devices, such as a device that incorporates the functionality of two or more of a media player, a cellular phone, a gaming platform, a personal data organizer, and so forth. For example, in the depicted embodiment, the multi-function device  70  is in the form of a tablet computer that may provide various additional functionalities (such as the ability to take pictures, record audio and/or video, listen to music, play games, and so forth). 
     In the depicted embodiment, the handheld device  70  includes an enclosure or body  72  that protects the interior components from physical damage and shields them from electromagnetic interference. The enclosure may be formed from any suitable material such as plastic, metal or a composite material and may allow certain frequencies of electromagnetic radiation to pass through to wireless communication circuitry within the handheld device  70  to facilitate wireless communication. 
     In the depicted embodiment, the enclosure  72  includes user input structures  32  (such as the depicted button  74  and touch sensitive elements  76  incorporated into display  12  to form a touch screen) through which a user may interface with the device  70 . Each user input structure  32  may be configured to help control a device function when actuated. For example, the button  74  may be configured to invoke a “home” screen or menu to be displayed. Other buttons, switches, rockers, and so forth may be provided to toggle between a sleep and a wake mode, to silence a ringer or alarm, to increase or decrease a volume output, and so forth. 
     In the depicted embodiment, the multi-function device  70  includes a display  12  that may be used to display a graphical user interface (GUI)  80  that allows a user to interact with the multi-function device  70 . The GUI  80  may include various layers, windows, screens, templates, or other graphical elements that may be displayed in all, or a portion, of the display  12 . The graphical elements may include icons  82  and other images representing buttons, sliders, menu bars, and the like. The icons  82  may be selected and/or activated via touching their locations on the display  12  in embodiments in which the display  12  is provided as a touch screen. 
     Generally, the GUI  80  may include graphical elements that represent applications and functions of the multi-function device  70 . For instance, in the depicted embodiment, an operating system GUI  80  may include various graphical icons  82 , each of which may correspond to various applications that may be opened or executed upon detecting a user selection (e.g., via keyboard, mouse, touchscreen input, voice input, etc.). The icons  82  may be displayed in a graphical dock  86  or within one or more graphical window elements  84  displayed on the screen of the display  12 . By way of example only, the depicted icons  82  may represent a presentation application  88 , such as Keynote® from Apple Inc., an application  90  for accessing the App Store® service from Apple Inc., an application  92  for accessing the iTunes® service from Apple Inc., as well as an e-reader/e-book application  94 . 
     In some embodiments, the selection of a particular icon  82  may lead to a hierarchical navigation process, such that selection of an icon  82  leads to a screen or opens another graphical window that includes one or more additional icons  82  or other GUI elements. By way of example only, the operating system GUI  80  displayed in  FIG. 3  may be from a version of the Mac OS® operating system, available from Apple Inc. 
     The multi-function device  70  also may include various external ports  34  that allow connection of the multi-function device  70  to external devices, such as computers, projectors, modems, telephones, external storage devices, and so forth. For example, one external port may be a port that allows the transmission and reception of data or commands between the multi-function device  70  and another electronic device, such as a computer. One or more of external ports  34  may be a proprietary port from Apple Inc. or may be an open standard I/O port. 
     With the foregoing discussion in mind, various techniques and algorithms for implementing aspects of the present disclosure on electronic devices  10  and associated hardware and/or memory devices are discussed below. For example, in certain implementations, an electronic device  10  may be employed to store and/or run a work productivity application or suite of applications. One example of such applications includes the Pages® word processing application, the Numbers® spreadsheet application, and the Keynote® presentation application, which are all provided within the iWork® application suite available from Apple Inc. of Cupertino, Calif. In certain embodiments, such applications, or aspects of such applications, may be encoded using a suitable object-oriented programming language, such as Objective-C, C++, C#, and so forth. 
     By way of example, a presentation application, such as Keynote® may be employed to generate and present slideshows, typically consisting of a sequential display of prepared slides. For example, turning to  FIG. 4 , an illustrative screen  120  of a presentation application is depicted in accordance with one embodiment of the disclosure. Such a presentation application may be stored as one or more executable routines in storage/memory  14  ( FIG. 1 ) and, when executed, may cause the display of screens, such as screen  120 , on a display  12 , such as a display configured for use as a touch screen. 
     Prior to discussing the use or features of a presentation application in accordance with the present disclosure, it should be appreciated that, as used herein, a “slide” should be understood to refer to a discrete unit on which one or more objects may be placed and arranged. Such slides should also be understood to be discrete units or elements of an ordered or sequential presentation, i.e., the slides are the pieces or units that are assembled and ordered to generate the presentation. Such a slide, may be understood to function as a container or receptacle for a set of objects (as discussed below) that together convey information about a particular concept or topic of the presentation. A slide may contain or include different types of objects (e.g., text, numbers, images, videos, charts, graphs, and/or audio, and so forth) that explain or describe a concept or topic to which the slide is directed and which may be handled or manipulated as a unit due to their being associated with or contained on the slide unit. 
     The order or sequence of the slides in a presentation or slideshow is typically relevant in that the information on the slides (which may include both alphanumeric (text and numbers) and graphical components) is meant to be presented or discussed in order or sequence and may build upon itself, such that the information on later slides is understandable in the context of information provided on preceding slides and would not be understood or meaningful in the absence of such context. That is, there is a narrative or explanatory flow associated with the ordering or sequence of the slides. As a result, if presented out of order, the information on the slides may be unintelligible or may otherwise fail to properly convey the information contained in the presentation. This should be understood to be in contrast to more simplistic or earlier usages of the term “slide” and “slideshow” where what was typically shown was not a series of multimedia slides containing sequentially ordered content, but projected photos or images which could typically be displayed in any order without loss of information or content. 
     As used herein, the term “object” refers to any individually editable component on a slide of a presentation. That is, something that can be added to a slide and/or be altered or edited on the slide, such as to change its location, orientation, size, opacity, color, or to change its content, may be described as an object. For example, a graphic, such as an image, photo, line drawing, clip-art, chart, table, which may be provided on a slide, may constitute an object. Likewise, a character or string of characters may constitute an object. Likewise, an embedded video or audio clip may also constitute an object that is a component of a slide. Therefore, in certain embodiments, characters and/or character strings (alphabetic, numeric, and/or symbolic), image files (.jpg, .bmp, .gif, .tif, .png, .cgm, .svg, .pdf, .wmf, and so forth), video files (.avi, .mov, .mp4, .mpg, .qt, .rm, .swf, .wmv, and so forth) and other multimedia files or other files in general may constitute “objects” as used herein. In certain graphics processing contexts, the term “object” may be used interchangeably with terms such as “bitmap” or “texture”. 
     Further, because a slide may contain multiple objects, the objects on a slide may have an associated z-ordering (i.e., depth) characterizing how the objects are displayed on the slide. That is, to the extent that objects on the slide may overlap or interact with one another, they may be ordered, layered or stacked in the z-dimension with respect to a viewer (i.e., to convey depth) such that each object is ordered as being above or beneath the other objects as they appear on the slide. As a result, in the event of an overlap of objects, a higher object can be depicted as overlying or obscuring a lower object. In this way, a slide may not only have a width and length associated with it, but also a depth (i.e., a z-axis). 
     Thus, as used herein, the term “slide” should be understood to represent a discrete unit of a slideshow presentation on which objects may be placed or manipulated. Likewise, an “object” as used herein should be understood to be any individually editable component that may be placed on such a slide. As discussed herein, the slide may include a “canvas” (see, for example, slide canvas  128  of  FIGS. 4-20 ) of fixed size that defines the space on the slide where objects can reside (e.g., be placed, moved, manipulated, and so forth. Further, as used herein, the term “transition” describes the act of moving from one slide to the next slide in a presentation. Such transitions may be accompanied by animations or effects applied to one or both of the incoming and outgoing slide. Likewise, the term “build” as used herein should be understood as describing effects or animations applied to one or more objects provided on a slide or, in some instances to an object or objects that are present on both an outgoing and incoming slide. For example, an animation build applied to an object on a slide may cause the object to be moved and rotated on the slide when the slide is displayed. Likewise, a dissolve out applied to an object on a slide may cause the object to fade out some time before the slide disappears from the display. 
     With the foregoing in mind, and turning to  FIG. 4 , it will be appreciated that, in certain embodiments a presentation application may provide multiple modes of operation, such as an edit mode, an animation mode, a presentation or play mode, and so forth. When in the edit mode, the presentation application may provide an interface for a user to add, edit, remove, or otherwise modify the slides of a slide show, such as by adding text, numeric, graphic, or video objects to a slide. Likewise, when in the animation mode, the presentation application may provide an interface for a user to apply and/or modify animation or effects applied to slide transitions between slides or to builds (e.g., animations, effects, and so forth) applied to objects on a slide. The edit and/or animation modes may also provide previews, full-screen or reduced in size, of how the slides will appears when presented (such as displaying the specified object builds and slide transitions). To display a created slide or a sequence of slides in a format suitable for audience viewing, a presentation mode of the presentation application may be employed which displays the slides, slide transitions, and object builds in a specified sequence. In some embodiments, the presentation application may provide a full-screen presentation of the slides in the presentation mode, including any animations, transitions, builds or other properties defined for each slide and/or object within the slides. 
     The screen  120  of  FIG. 4  represents a screen that may be displayed when one embodiment of a presentation application is in an edit mode, such as for slide creation or modification. In the depicted example, the screen  120  includes three panes: a slide organizer or navigator pane  124 , a slide canvas  128 , and a toolbar  132  for creating and editing various aspects of a slide  140  of a presentation. By using these panes, a user may select a slide  140  of a presentation, add objects  142  to and/or edit objects  142  on the slide  140  (such as the depicted graphic objects and character objects), and animate or add effects related to the slide or the objects  142  on the slide  140 . 
     The navigator pane  124  may display a representation  150  of each slide  140  of a presentation that is being generated or edited. The slide representations  150  may take on a variety of forms, such as an outline of the text in the slide  140  or a thumbnail image of the slide  140 . Navigator pane  124  may allow the user to organize the slides  140  prepared using the application. For example, the user may determine or manipulate the order in which the slides  140  are presented by dragging a slide representation  150  from one relative position to another or may designate slides  140  to be skipped during a presentation. In certain embodiments, the slides representations  150  in the navigator pane  124  may be indented or otherwise visually set apart for further organizational clarity. In such cases, the user may be able to expand/collapse the indented slides to facilitate interactions with and/or review of the navigator pane  124 . In addition, in certain embodiments, the navigator pane  124  may include an option  152  which, when selected, adds a new slide to the presentation. After being added, the slide representation  150  for such a new slide may be selected in the navigator pane  124  to display the slide  140  on the slide canvas  128  where objects  142  may be added to the new slide  140  and/or the properties of the new slide  140  may be manipulated. 
     In certain implementations, selection of a slide representation  150  in the navigator pane  124  results in the presentation application displaying the corresponding slide information on the slide canvas  128 . For example, for a selected slide representation (here depicted as slide “3”, identified by highlight region  154 ) the corresponding slide  140  may be displayed on the slide canvas  128 . The displayed slide  140  may include one or more suitable objects  142  such as, for example, text, images, graphics, video, or any other suitable object. In some embodiments, a user may add or edit features or properties of a slide  140  when displayed on the slide canvas  128 , such as slide transitions, slide background, and so forth. In addition, in some embodiments a user may add objects  142  to or remove objects  142  from the slide  140  or may manipulate an object  142  on the slide  140 , such as to change the location or appearance of the object  142  or to add or edit animations or builds to the object  142 . The user may select a different slide  140  to be displayed for editing on slide canvas  128  by selecting a different slide representation  150  from the navigator pane  124 , such as by touching the displayed slide representation  150  in a touch screen embodiment of the device  10 . 
     In the depicted implementation a user may customize objects  142  associated with the slide  140  or the properties of the slide  140  using various tools provided by the presentation application. For example, in certain embodiments, when in the edit mode, selection of a slide  140 , object  142 , and/or toolbar option  158  may cause the display of an interface presenting one or more selectable options for the selected slide  140  or object  142 , which a user may then select, deselect, or otherwise manipulate to modify the slide  140  or object  142  as desired. For example, selection of certain toolbar options  158 , such as an inspector or information icon  160 , may cause properties of the selected object  142  or slide  140  to be displayed for review and/or modification. Likewise, selection of a play mode icon  164  from among the toolbar options  158  may cause the presentation application to enter a presentation mode in which the slides  140  of the slide presentation are sequentially displayed on the display  12  or an attached display device. 
     Similarly, in one embodiment selection of an animation mode icon  162  from among the toolbar options  158  may cause the presentation application to enter an animation mode from which builds or animations applied to objects and/or transitions assigned to slides may be previewed, reviewed, edited, and/or manipulated. Turning now to  FIG. 5 , an example of an animation mode screen  170  that might be invoked is depicted. In this example, a slide representation  150  may be selected in the navigator pane  124 , as in the edit mode. The selected slide  140  is displayed on the slides canvas  128 . In addition, the screen  170  may include instructions  172  or explanatory material providing guidance to a user. In the depicted example, the user may exit the animation mode and return to the edit mode by selection of an exit button  168  or by providing another recognized exit command. 
     When in the animation mode, additional animation specific information may be displayed within the navigator pane  124  and/or in the slide canvas  128 . For example, one or more object build indicators  174  and/or slide transition indicators  178  may be displayed on the slide representations  150  in the navigator pane  124 . Such object build indicators  174  and slide transition indicators  178  may provide a visual indication as to whether objects  142  having associated builds (e.g., animations) are present on a corresponding slide  140 . Thus, a user need only review the navigator panel  124  to determine what slides  140  have an animated transition associated with them and/or which slides  140  contain object  142  that have associated builds. 
     For example, in the depicted implementation, the object build indicator  174  is provided as a column of circular markers on the slide representation  150 . In one such embodiment, the markers may be shaded, color coded or color filled (such as yellow, red, green, black, or blue filled) to make the object build indicators  174  more visible. As will be appreciated, though circular markers are depicted as the object build indicators  174  in  FIG. 5 , other types, shapes, or colors of markers or visual indicators may be employed to indicate the presence and/or number of objects  142  with builds present on a slide  140 . For example, square, triangular, oval, rectangular, or other shapes of markers of any color or shading may be employed as object build indicators  174 , as might any other suitable visual representation. 
     Similarly, the slide transition indicator  178 , here depicted as a triangular or “corner cut-out” type indicator on the slide representations  150 , may provide a visual indication that one or more animated transitions are associated with the corresponding slide  140 . For example, the corresponding slide  140  may have an animated transition when the slide  140  is introduced or exited during a presentation. As with the object build indicators  174 , the slide transition indicators may be shaded, color coded or color filled (such as yellow, red, green, black, or blue filled) to make the slide transition indicators  178  more visible. As will be appreciated, though triangular or corner cut-out markers are depicted as the slide transition indicators  178  in  FIG. 5 , other types, shapes, or colors of markers or visual indicators may be employed to indicate the presence of a slide transition associated with a corresponding slide  140 . For example, square, circular, oval, rectangular, or other shapes of markers of any color or shading may be employed as slide transition indicators  174 , as might any other suitable visual representation. 
     In addition, in certain embodiments additional slide transition and object build information may be provided for a selected slide  140  when in an animation mode. Notably, in certain embodiments, a user interface is attached and/or associated with each slide or object when the slide or object is selected, as opposed to a generic or general inspector or information window being opened without a connection to the selected slide or object. For example, as depicted on screen  170 , a transition marker  182  may be displayed for a selected slide  140 , here indicated by a highlighted  154  slide representation  150  in the navigator pane  124 . In one embodiment, the transition marker  182  may display the type of transition effect associated with a selected slide  140 . For example, as indicated by the absence of a slide transition indicator  178 , the depicted selected slide  140  in  FIG. 5  does not have an associated transition effect. This absence of a transition effect is corroborated by the transition marker  182  which indicates by text that the transition effect for the selected slide  140  is “None”. If a transition effect were associated with the selected slide, the transition marker  182  would instead display text identifying or describing the type of transition effect associated with the slide  140 , such as Anagram, Cube, Doorway, and so forth. In addition, the transition marker  182  may include a selectable icon  186  which upon selection displays additional transition information or options, as discussed in greater detail below. 
     As noted above, in certain implementations additional object and/or object build information may also be provided for a selected slide when in an animation mode. For example, as depicted on screen  170  of  FIG. 5 , each object  142  having a build may be marked or tagged with a build indicator  190 . Conversely, in the depicted embodiment, objects  142  with no associated build are not displayed with a corresponding build indicator  190 . In the depicted embodiment, the build indicator may indicate a build sequence, i.e., the order in which builds are applied to the respective objects  142  on a slide. For example, an object  142  having a build that is earlier in the build order may be animated prior to an object  142  having a build that is later in the build order. In addition, builds may be applied to objects to move the object  142  onto the screen (i.e., a build-in) or to move an object  142  off of the screen (i.e., a build-out) and an object  142  may have both an associated build-in for introducing the object  142  and separate build-out for removing the object  142 . Thus, there may be a separate sequence or order associated with the build-in of objects  142  and with the build-out of objects  142 . For example, turning to  FIG. 5 , the build indicators  190  display a build-in order for the objects  142 , with the leftmost object building in prior to the rightmost object. 
     Turning to  FIG. 6 , in one embodiment a build marker  194  may be displayed for a selected object  142  on the slide canvas  128 . Such a build marker  194  may convey additional object build information, such as naming or describing a build-in and/or build-out effect to be applied to the selected object and the respective sequence or order associated with each listed build-in and/or build-out effect. For example, as depicted in  FIG. 6 , a build marker  194  is shown that indicates that a Dissolve animation is used to build-in the selected object and that the Dissolve animation is the second build in the build-in order for the slide  140 . In this example, the right-most half of the build marker  194  conveys build-out information, here depicting that no build out animation is currently specified. In the absence of a selected build-out and sequence, a selectable icon  196  may be provided which, upon selection, would allow the user to add a build-out for the selected object and/or to specify the order in which such a build-out would be performed. 
     In one embodiment, as depicted in  FIGS. 5 and 6 , to simplify the user interface and to preserve screen space for depicting the respective slides and objects, only one animation control (e.g., transition marker  182 , build marker  194 , or transition box  200  and build box  240  discussed below) may be displayed at a time. For example, if a user has most recently selected a slide representation  150  in the navigator pane  240 , a slide-related animation control (e.g., transition marker  182  or transition box  200 ) may be displayed. Conversely, if a user has most recently selected an object  142  displayed on the slide canvas  128 , an object-related animation control (e.g., build marker  194  or build box  240 ) may be displayed. Thus, in such an embodiment, only a slide-related animation control or an object-related animation control would be displayed at one time. However, in other embodiments, both a slide-related animation control and an object-related animation control might be concurrently displayed. 
     With the foregoing examples and conventions in mind, an example is provided of one implementation by which an animation may be added or changed for a slide  140 . Turning to  FIG. 7 , an animation mode screen is depicted in which a slide representation  150  is selected (as indicated by highlight region  154 ) and the corresponding slide  140  is displayed on the slide canvas  128 . In the depicted example, a transition marker  182  is associated with the selected slide representation  150  and indicates that the selected slide  140  does not currently include a transition effect. 
     To add a transition effect to the selected slide, a user may select the selectable icon  186  provided on the transition marker  182  to cause the display of various transition options. For example, turning now to  FIG. 8 , selection of the selectable icon  86  of  FIG. 7  may cause a transition box  200  to be displayed that lists available transitions and transition options. In this example, the transition box may list available transition effects  204  which may be selected or may provide an option  208  for not implementing a transition effect for the selected slide. In the example depicted in  FIG. 8 , no transition effect is currently selected and this is indicated by the visual indicator  210  (here depicted as a check mark) displayed next to the “None” option  208 . 
     In addition, depending on the transition effect  204  selected, a user may also select an options selection  212  to configure one or more options (such as duration, delay, direction, what input initiates the transition, and so forth) that pertain to the selected transition effect. Likewise, to list the relevant transition effects (or to return to a listing of the relevant transition effects after viewing options), the user may select a displayed effects selection  216 . In addition, in the depicted embodiment, a preview button  220  may be provided which, when selected, displays the selected slide  140  and selected transition effect  204  on the slide canvas  128 . Once the preview is completed, the screen may once again display what was shown prior to the preview, such as the transition box  200  and so forth. In certain embodiments, regions around slide canvas  128  may be dimmed or hidden from view for the duration of the preview. If a transition effect is assigned to a selected slide  140 , a transition marker may be displayed on the slide representation  150  in the navigator pane  124 , as discussed above. 
     In the example depicted in  FIG. 9 , the user has selected a first effect as a transition effect for the selected slide. Thus, in this example the visual indicator  210  (here depicted as a check mark) is now displayed next to the “Effect # 1 ” selection among the listed transition effects  204 . In addition, once a slide transition is selected for the selected slide  140 , the corresponding slide representation  150  in the navigator pane  124  may be updated to include a slide transition indicators  178 , as depicted in  FIG. 9 . Further, once a transition effect is selected using the transition box  200 , the transition box  200  may be closed and/or minimized so that a transition marker  182  is once again displayed proximate to the selected slide representation  150  in the navigator pane  124 , as depicted in  FIG. 10 . In this example, because the selected slide now has an associated transition effect, the transition marker  182  now displays the selected transition effect (here listed as “Effect # 1 ” by way of example) for the slide  140 . 
     While the preceding describes aspects of the present disclosure related to assigning, previewing, reviewing, and/or modifying transition effects associated with slides  140  of a slide presentation, other aspects of the disclosure relate to assigning, previewing, reviewing, and/or modifying builds (e.g., animations) associated with objects  142  on a slide  140 . For example, turning now to  FIG. 11 , a slide  140  is displayed on the slide canvas  128  of an animation mode screen  170 . The selected slide  140  includes two objects  142  with no associated builds, as evidenced by the absence of build indicators  190  on the objects  142 . 
     In the depicted example, selection of an object  142 , such as the leftmost object, may cause a build marker  194  to be displayed. In this example, due to the absence of builds on the selected object, the build marker  194  indicates that the current build-in and build-out for the selected object is “None”. A selectable icon  196  is provided for each of the build-in and build-out halves of the build marker  194 , allowing a user to select the selectable icon  196  to view available build-in or build-out effects for the selected object. For example, turning now to  FIG. 12 , selection of the selectable icon  196  associated with the build-in option may cause a build box  240  to be displayed that lists available builds and build options for the selected object. In this example, the build box  240  may list available build effects  244  which may be selected or may provide an option  248  for not implementing a build effect for the selected object. In the example depicted in  FIG. 12 , no build effect is currently selected and this is indicated by the visual indicator  210  (here depicted as a check mark) displayed next to the “None” option  248 . 
     Depending on the build effect  244  selected, a user may also select a number of other build characteristics to modify, such as options selection  252  to configure one or more options (such as duration, delay, direction, what input initiates the transition, and so forth) that pertain to the selected build effect, order selection  256  to configure where in the build-in sequence the current build will be placed, and delivery selection  260  to configure aspects of how the build will be implemented (such as whether text is delivered all at once or by paragraph). Likewise, to list the relevant build effects (or to return to a listing of the relevant build effects after viewing other build characteristics), the user may select a displayed effects selection  264 . As will be appreciated, in various embodiments, the tabs representing options  252 ,  256 ,  260  and  264  may be visually distinguished, such as by dimming or graying out, to indicate which option is currently selected and/or which tabs are not selected or are disabled. In this way a user may be able to easily determine which options are currently selected and displayed within the build box  240 . 
     In the example depicted in  FIG. 13 , the user has selected a first effect as a build for the selected object. Thus, in this example the visual indicator  210  (here depicted as a check mark) is now displayed next to the “Effect # 1 ” selection among the listed builds  244 . In addition, once a build is selected for the selected object, the corresponding slide representation  150  in the navigator pane  124  may be updated to include an object build indicator  174 , as depicted in  FIG. 13 . 
     Further, once a build is selected using the build box  240  and/or once the build box  240  is closed or minimized, a build indicator  190  may be displayed on or proximate to the selected object  142 , as depicted in  FIG. 14 . In this example, because the selected object now has an associated build-in effect, the build indicator  190  now displays the build-in order for the object  142 . For example, in the depicted example, the build indicator  190  indicates that the build-in performed on the selected object is first in the build-in sequence. As will be appreciated, though the present discussion relates to build-in order by way of explanation, the same concepts apply to build-out order as well and an object having both a build-in and build-out applied may have both sequence positions conveyed by the build indicator  190 . For example, the build indicator  190  may, by convention, display the build-in sequence number on the left and the build-out sequence number on the right. Similarly, the build-in and build-out sequence numbers may be visually differentiated, such as by different colored numerals or background (such as displaying a yellow background for the build-in sequence number and a black background for the build-out sequence number). Likewise, a once a build-in and/or build-out effect is selected, a build marker  194 , when displayed for a selected object  142 , may indicate the selected build-in and/or build-out effect, as depicted in  FIG. 5 . 
     In addition, as noted above, the user may specify one or more options related to a build effect. For example, after selecting a build effect from the available build effects listed in a build box  240  ( FIG. 13 ), the user may invoke an options selection  252  to cause the display of an options interface  270 , as depicted in  FIG. 15 . In one such embodiment, the options interface  270  may allow parameters of the selected build effect, such as direction, duration, initiation event, delay, and so forth, to be configured by the user. For instance, in the depicted example, a slider control  274  may be provided to allow the user to adjust the duration over which the selected build is applied. In the depicted example, the current value  278  of the duration may be displayed beside the slider control  274  so that a user may observe the change in duration as he or she adjusts the slider control  274 . 
     In the depicted example, a virtual dial control  282  is also depicted. In one embodiment, such a virtual dial control  282  may be used in conjunction with a touch screen or other touch sensitive structure or display where a physical dial or interface structure is not available and/or desirable. In such an embodiment, the user may adjust or turn the dial control  282  using the touch sensitive interface to specify a direction (or other suitable parameter) that the selected build effect moves toward or from. For example, in the depicted view, the selected build-in effect would presumably build-in from or toward the right. As will be appreciated, different build effects may have different directions they build from or toward. As a result, different numbers and/or placements of detents  286  may be provided with respect to the dial control  282 , depending on the build effect being configured. For example, in some implementations only two detents may be present (such as left and right or up and down). In other implementations four detents may be present (such as for the cardinal or diagonal directions). Likewise, in other implementations eight or sixteen detents may be presented. Further, as will be appreciated, depending on the build effect being configured, in some embodiments the detents may be evenly spaced apart while in other embodiments the detents may not be evenly spaced apart. In embodiments in which the direction (or other suitable parameter) may be arbitrary, no detents may be provided and the user instead may configure a direction from anywhere along the dial control  282 . In certain embodiments where a discrete set of directions are available and/or where the options are not well suited for selection with a dial (such as clockwise, anticlockwise, random, and so forth) a list representation may be displayed for the user to select from instead of the virtual dial control  282 . 
     As depicted, in certain embodiments, other build options may also be present, such as additional sliders, dials, lists of selections, and so forth, as indicated by the presence of scroll bar  288 . By use of such a scroll bar  288 , the size of the open window may be reduced while still allowing the user to access a range of options. In one embodiment, the more commonly used options may be initially displayed in the options interface  270  while less commonly used options may be accessed by scrolling down using the scroll bar  288 . 
     Further, as discussed above, the user may specify the order in which build effects are applied. For example, when configuring a build selected for an object, the user may invoke the order selection  256  of a build box  240  or similar interface. The order selection  256  may in turn cause the display of a build order interface  290 , as depicted in  FIG. 16 . Such a build order interface  290  may be specific to either build-in order or build-out order for objects  142  on the slide  140  in embodiments where objects may have both a build-in effect and a build-out effect. That is, the displayed build order interface  290  may only allow review and or alteration of the build-in order or the build-out order at one time, though in certain embodiments a tab or other selection mechanism may be provided to easily switch between the build-in and build-out lists. In one example, the build order interface  290  relates only to a build-in or build-out order at a given time and depicts the respective items or objects in the build-in or build-out queue  294 . 
     In one embodiment, the build order interface  290  displays all of the builds on the slide  140 , not just the build associated with the selected object. In such an embodiment, the user may perform a global rearrangement of the ordering of animations for the selected slide  140  since all of the build-in and/or build-out animations on the slide are listed. For example, the user may rearrange the build queue  294 , such as by dragging listed entries to different positions and/or by invoking an order entry screen from which a sequence number may be assigned for a specific object and/or build or for each object and/or build represented on a selected slide  140 . In one embodiment, by selecting different build order table entries, focus may be switched to the different respective objects associated with current build order, i.e., by selecting an entry in the build order queue, different objects  142  may be selected. 
     Further, in the depicted example, once the build order is specified, the build indicator  190  displayed on or proximate to the respective object may convey the respective build-in sequence information  298  and build-out sequence information  302 , if both a build-in and build-out are associated with the object. To distinguish between build-in and build-out information in such embodiments, the build-in and build-out information may be visually distinguished. For example, the build indicator  190  may display the build-in sequence number  298  on the left and the build-out sequence number  302  on the right and/or may use different colored numerals or background to distinguish between build-in and build-out information. 
     In addition, in the depicted embodiment, a preview button  220  may be provided which, when selected, displays the selected slide  140  and associated object builds on the slide canvas  128  (see, for example,  FIG. 17  depicting an object  142  sliding in from the side). Alternatively, the preview may occur automatically upon selection and/or modification of a build from the available list. Once the preview is completed, the screen may once again display what was shown prior to the preview, such as the build box  240  and so forth. As depicted in  FIG. 17 , in certain embodiments, regions around slide canvas  128  may be dimmed or hidden from view for the duration of the preview. Once the preview is over, the dimmed regions may return to their normal degree of visibility. Alternatively, for a full screen preview, the navigator pane  124 , title, and tool bar  132  may be slid off the screen or otherwise removed from the viewing area and the slide canvas  128  is scaled-up to fill the available screen space. Upon completion of the preview, the slide canvas  128  may be scaled back down and the navigator pane  124 , title, and tool bar  132  may be slid back into view or otherwise returned to the viewing area. 
     The preceding discussion distinguishes between transitions applied to slides  140  of a presentation and builds (e.g., animations) applied to objects  142  on a slide being displayed. In some instances, however, an object  142  may be present on consecutive slides  140  and may be undergo particular builds due to this persistence. For example, such a persistent object may be animated during a slide transition such that the appearance of the object in both the outgoing and incoming slide is bridged by the animation. Such an animation may be generated automatically, i.e., without a user having to provide additional instructions. Thus, in such a situation, a slide transition is involved in conjunction with an animation of an object that is present on both the incoming and outgoing slides. 
     Such a slide transition and object build scenario may be accommodated by certain embodiments of the present disclosure. For example, turning to  FIG. 18 , a transition box  200  is depicted that lists a Magic Move® transition found in certain versions of the Keynote® presentation application available from Apple Inc. Upon selection of the Magic Move® transition, denoted by visual indicator  210 , a dialog box  310  is displayed, as depicted in  FIG. 19 . Because the Magic Move® transition relates to at least some objects being present on the outgoing and incoming slides  140 , the dialog box  310  offer the user an option to duplicate the presently selected slide, thereby inserting a duplicate slide with duplicate objects as the next slide in the navigator pane  124  (as depicted in  FIG. 20 ) if the user elects to do so. Though the objects may be duplicated, any builds associated with the objects would typically not be duplicated on the new slide. In this manner, there slide  140  to which the Magic Move® transition has been applied will have at least some objects  142  in common with the subsequent slide, thus making the Magic Move® transition possible. 
     For example, turning to  FIG. 20 , a user has selected “Yes” from the dialog box  310  depicted in  FIG. 19 , resulting in the creation of a duplicate slide (slide “ 4 ”) with duplicated objects, which is now the selected slide in  FIG. 20 . In the depicted example, the duplicated objects are each displayed with a build indicator  190  as discussed above. However, in this example, the build indicator  190 , instead of displaying a numeral reflecting the build order sequence of each object, displays a symbol (here a star) or other visual indicator to signify that these objects tagged in this manner are currently part of a build related to the slide transition. In certain embodiments, the objects so tagged may still be subject to other builds and may thus have other build and build sequence information which may be conveyed by the build indicator  190  and/or build marker  194 . Further, the visual indicator and/or the background of the build indicator may be color coded or otherwise visually distinguished such that those object undergoing a Magic Move® transition on the outgoing slide are distinguishable from the same objects on the incoming slide. That is, the build indicator  190  may visually convey whether an object is undergoing a build in which the object is introduced from the preceding slide or is carried over in to the subsequent slide. 
     As will be appreciated, the foregoing implementations and embodiments may be embodied as computer-executable code stored on an electronic device  10  and executed by a processor  18  of such a device  10 . For example, the approaches discussed herein may be embodied as routines and/or algorithms of a presentation application stored and executed on an electronic device  10 . In one such embodiment, the algorithms involved in implementing the present user interface aspects may be characterized as described in the flowchart of  FIG. 21 . As depicted in this flowchart, in one embodiment, a presentation application may be in an edit mode (block  344 ), such as for creating or modifying a slide of a slideshow presentation. In this example, the presentation application may, in response to a user input, enter an animation mode (block  348 ) with respect to a slide, object, or slideshow presentation. 
     When in the animation mode, slide transition information for a selected slide may be displayed (block  352 ) and/or object build information for a selected object may be displayed (block  356 ). Such information may be displayed so that it is attached to or proximate to the selected slide or object and may be implemented to as to reduce the amount of open windows or objects displayed on the screen (i.e. to reduce screen clutter) and/or to simplify operation for the user. For example, in one embodiment, only a single transition control or build control would be displayed at one time, thereby limiting the options and/or choices confronting a user. In one embodiment, a user input may be received (block  360 ) indicating that a slide transition or object build is to be added, reviewed, or modified. In response to this input, the application may display (block  364 ) a user interface, such as a transition box  200  or build box  240 , attached or proximate to the selected object or slide. The user may then interact with the user interface to provide one or more inputs that are received (block  368 ) by the application and which are used to add or modify an object build or slide transition (block  372 ). Alternatively, the user may decided to make no additions or changes and may instead exit the user interface (block  376 ). In one embodiment, once the additions and/or changes are received, a preview of the slide transition and/or the object build may be provided (block  380 ) in a full screen or slide canvas mode, generally corresponding to a full size preview of the effect. Once all additions and/or changes have been made with respect to the selected slide transitions and/or object builds, the animation mode may be exited. 
     The specific embodiments described above have been shown by way of example, and it should be understood that these embodiments may be susceptible to various modifications and alternative forms. It should be further understood that the claims are not intended to be limited to the particular forms disclosed, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure.
