Non-linear presentation canvas

[0001] Prior to the availability of presentation applications, such as POWERPOINT from MICROSOFT CORPORATION and KEYNOTE from APPLE INC., users often relied on printed materials or manual writing surfaces to supplement an oral lecture. Examples of printed materials include handouts, pamphlets, overhead transparencies, posters, charts, photographic slides, and the like. Examples of manual writing surfaces include chalkboards, whiteboards, and the like.

[0002] These early presentation mediums had a number of drawbacks. For example, an audience may have difficulty focusing on a speaker while reading the handouts. Further, generating pamphlets, posters, charts, and photographic slides may be cost prohibitive, especially when the presentation is given in a limited number. With manual writing surfaces, the audience may be focused on taking notes, instead of listening to the speaker. Also, the effectiveness of manual writing surfaces depends heavily on the handwriting skills of the speaker.

[0003] The advent of presentation applications has provided users with the ability to generate and display rich presentations embedded with text, graphics, and other multimedia content. A conventional presentation application provides an editor interface for generating a presentation and a slideshow interface for displaying the presentation. A conventional editor interface provides a blank template containing multiple slides. The user can insert text, graphics, sound, and other multimedia into the slides via the editor interface. The slides can then be displayed via the slideshow interface in a linear presentation flow. For example, common operations for traversing slides in the presentation include “next slide” for viewing the next slide in a predefined sequence and “previous slide” for viewing the previous slide in the predefined sequence.

[0004] In conventional presentation applications, the content inserted into the slides is generally limited to the size of the slide, which is usually a finite space. In order to insert large content (e.g., large text, detailed charts, process maps) greater than the size of the slide, the large content is usually resized or manually divided into smaller portions. Each smaller portion can then be inserted into a separate slide. Downsizing the large content may decrease the quality (e.g., the resolution) of the content. Dividing the content into smaller portions may be time-consuming and require the use of separate editing software. Also, some file types, such as detailed charts and spreadsheets, may not be amenable to a division without entirely recreating the file.

[0005] Further, conventional presentation applications are generally not capable of handling interactive content, such as websites and demonstrations, without launching an external program. Launching an external program may cause a new window to open and disrupt the linear presentation flow of the slideshow.

[0006] It is with respect to these considerations and others that the disclosure made herein is presented.

[0007] Technologies are described herein for providing a non-linear presentation canvas. In particular, through the utilization of the technologies and concepts presented herein, a user can generate a presentation by inserting multimedia files, documents, hyperlinks, text, and nested workspaces onto a non-linear presentation canvas, which provides a virtually infinite workspace. Like the presentation canvas, each nested workspace also provides a virtually infinite workspace onto which additional objects may be inserted. Further, nested workspaces may be embedded within other nested workspaces to a virtually infinite degree to create layers of workspaces.

[0008] According to one aspect presented herein, a computer program provides a non-linear presentation canvas. The non-linear presentation canvas is a virtual space onto which documents, text, multimedia files, hyperlinks, and other data can be placed. The computer program further displays content previews corresponding to the objects inserted onto the non-linear presentation canvas. The content previews are selectable to display the corresponding objects.

[0009] According to embodiments, the non-linear presentation canvas is infinitely zoomable and panable in a smooth and seamless manner. In particular, the computer program provides functionality for smoothly zooming into and out of the non-linear presentation canvas, documents, multimedia files, text, hyperlinks, and nested workspaces placed thereupon. Further, the computer program provides functionality for allowing a user to pan over the non-linear presentation canvas.

[0010] It should be appreciated that the above-described subject matter may also be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable medium. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.

[0011] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended that this Summary be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

[0024] The following detailed description is directed to technologies for providing a non-linear presentation canvas. While the subject matter described herein is presented in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations may be performed in combination with other types of program modules.

Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like.

[0025] In the following detailed description, references are made to the accompanying drawings that form a part hereof, and which are shown by way of illustration specific embodiments or examples. Referring now to the drawings, in which like numerals represent like elements through the several figures, aspects of a computing system and methodology for providing a non-linear presentation canvas will be described. In particular, FIG. 1 shows an illustrative screenshot 100 of a file folder 102 and a non-linear presentation canvas (hereinafter referred to as “presentation canvas”) 104. The file folder 102 is a standard file folder such as those provided by most modern operating systems, such as WINDOWS from MICROSOFT CORPORATION, MAC OS X from APPLE INC., and LINUX. As shown in FIG. 1, the file folder 102 includes a number of multimedia files stored therein, such as a video file 106, an audio file 108, and a spreadsheet file 110. The file folder 102 also includes an image folder 112 that contains images (not shown).

[0026] The presentation canvas 104 is a virtually infinite space onto which documents, text, multimedia files, hyperlinks, nested workspaces, and other types of objects can be inserted. The presentation canvas 104 includes a first nested workspace 114, a second nested workspace 116, and a third nested workspace 118. The third nested workspace 118 is embedded within the second nested workspace 116. Each of the nested workspaces 114-118 also includes a virtually infinite space in which multimedia files, hyperlinks, and nested workspaces can be inserted.

[0027] The first nested workspace 114 includes a video content preview 120, an audio content preview 122, and a spreadsheet content preview 124. In an illustrative example, the video content preview 120 is a graphical representation of the video file 106. For example, the video content preview 120 may be a screen capture from the video file 106. The audio content preview 122 is a graphical representation of the audio file 108. For example, the audio content preview 122 may include the title of a song included in the audio file 108 or a graphical waveform representation of the audio file 108. The spreadsheet content preview 124 is a graphical representation of the spreadsheet file 110. For example, the spreadsheet content preview 124 may include a rendering of a portion of the spreadsheet file 110.

[0028] The second nested workspace 116 includes an image stack content preview 126, and the third nested workspace 118 includes a website content preview 128. The image stack content preview 126 is a graphical representation of the images contained in the image folder 112. The website content preview 128 is a graphical representation of given hyperlink. For example, the website content preview 128 may be a screen capture of a website corresponding to the given hyperlink. It should be appreciated that the stack content preview may be also be utilized to represent multiple hyperlinks or a plurality of other types of multimedia files.

[0029] The multimedia files, hyperlinks, and other objects may be inserted onto the presentation canvas 104 in any suitable manner. As previously mentioned, a content preview representing the underlying inserted multimedia file or hyperlink may be displayed on the presentation canvas 104. The content preview may be moved, oriented, and resized in any suitable manner. In one embodiment, the content preview is a live preview of the underlying multimedia file or hyperlink. In other embodiments, the content preview may also be an icon or other suitable pre-rendered image.

[0030] In one embodiment, a multimedia file is dragged onto the presentation canvas 104 via a suitable input device, such as a mouse, stylus, or touchpad. For example, as illustrated in FIG. 1, the video file 106 may be dragged from the file folder 102 onto the presentation canvas 104 as shown by the dotted representation 130 of the video file 106. Once the video file 106 is dragged into the presentation canvas 104, the presentation canvas 104 displays the video content preview 120 representing the video file 106. In another embodiment, a multimedia file is inserted onto the presentation canvas 104 via a file menu.

[0031] Turning now to FIG. 2A, an illustrative file menu 200 is shown, in accordance with one embodiment. Although not so illustrated, the presentation canvas 104 may include a selectable option for inserting a multimedia file via the file menu 200. As illustrated in FIG. 2A, the file menu 200 includes a directory portion 202 which includes a listing of a portion of the files in a given directory. The directory portion 202 displays the video file 106, the audio file 108, and the spreadsheet file 110. The file menu 200 further includes a file name entry portion 204 where a user can input the name of a file. In an illustrative example, the name of the audio file 108 has been typed into the file name entry portion 204. Upon a user selecting an enter button 206, the presentation canvas 104 displays the audio content preview 122 representing the audio file 108, as illustrated in FIG. 1.

[0032] In yet another embodiment, a hyperlink or other suitable remote link (e.g., a link to a remote file) may be inserted onto the presentation canvas 104. Turning now to FIG. 2B, an illustrative hyperlink menu 210 is shown, in accordance with one embodiment. Although not so illustrated, the presentation canvas 104 may include a selectable option for inserting a hyperlink via the hyperlink menu 210. As illustrated in FIG. 2B, the hyperlink menu 210 includes a uniform resource locator (“URL”) entry portion 212 where a user can enter a hyperlink. In an illustrative example, the hyperlink “http://www.microsoft.com” is entered into the URL entry portion 212. Upon a user selecting an enter button 214, the presentation canvas 104 displays the website content preview 128 representing the hyperlink “http://www.microsoft.com.” It should be appreciated that other methods for inserting multimedia files and hyperlinks may be similarly utilized. The insertion of nested workspaces is described in greater detail below with respect to FIGS. 4A-4C.

[0033] Referring again to FIG. 1, during a presentation, a user may zoom and pan across various portions of the presentation canvas 104 in a smooth and seamless manner. Upon reaching a desired portion of the presentation canvas 104, a user may select one of the content previews, such as the content previews 120-128 on the presentation canvas 104, to access the corresponding multimedia file or website. In particular, a user may select one of the content previews 120-128 via a suitable input device. In one example, selecting the video content preview 120 accesses an embedded video player for playing video file 106.

[0034] Turning now to FIG. 3A, an exemplary embedded video player 302 adapted to play the video file 106 is shown, in accordance with one embodiment. The embedded video player 302 is opened within the presentation canvas 104, eliminating the need to open an external video player, such as WINDOWS MEDIA PLAYER from MICROSOFT CORPORATION, QUICKTIME from APPLE INC., and REALPLAYER from REALNETWORKS INC. The embedded video player 302 may be resized to fill a portion of the screen or the entire screen.

[0035] In a second example, selecting the spreadsheet content preview 124 accesses an embedded spreadsheet viewer for viewing the spreadsheet file 110. Turning now to FIG. 3B, an exemplary embedded spreadsheet viewer 312 adapted to display the spreadsheet file 110 is shown, in accordance with one embodiment. The embedded spreadsheet viewer 312 is opened within the presentation canvas 104, eliminating the need to open an external spreadsheet program, such as EXCEL from MICROSOFT CORPORATION and LOTUS 1-2-3 from INTERNATIONAL BUSINESS MACHINES CORPORATION. The embedded spreadsheet viewer 312 may be resized to fill a portion of the screen or the entire screen.

[0036] In a third example, selecting the image stack content preview 126 of FIG. 1 accesses an embedded image viewer for viewing a plurality of image files corresponding to the image stack content preview 126. Turning now to FIG. 3C, an exemplary embedded image viewer 322 adapted to display the plurality of image files is shown, in accordance with one embodiment. The embedded image viewer 322 is opened within the presentation canvas 104, eliminating the need to open an external image program, such as WINDOWS PICTURE AND FAX VIEWER from MICROSOFT CORPORATION and PREVIEW from APPLE INC.

[0037] As shown in FIG. 3C, the embedded image viewer 322 displays a plurality of thumbnail images 324a-324f. By selecting one of the thumbnail images 324a-324f, a user can view the actual corresponding image. The embedded image viewer 322 may be resized to fill a portion of the screen or the entire screen. A user may also zoom into the thumbnail images to generate a larger view of the corresponding image.

[0038] In a fourth example, selecting the website content preview 128 of FIG. 1 accesses an embedded web browser for viewing a hyperlink corresponding to the website content preview 128. Turning now to FIG. 3D, an embedded web browser 324 adapted to display the hyperlink is shown, in accordance with one embodiment. The embedded web browser 332 is opened within the presentation canvas 104, eliminating the need to open an external web browser, such as INTERNET EXPLORER from MICROSOFT CORPORATION, FIREFOX from MOZILLA CORPORATION, and SAFARI from APPLE INC. As illustrated in FIG. 3D, the embedded web browser 332 displays web content 334 from the hyperlink “http://www.microsoft.com.” The embedded web browser 324 may be resized to fill a portion of the screen or the entire screen.

[0039] By directly embedding the multimedia viewers, such as the video player 302, the spreadsheet viewer 312, the image viewer 322, and the web browser 324, into the presentation canvas 104, the flow of a given presentation is not interrupted by opening an external software program. To increase the speed of opening these embedded multimedia viewers, the functionality provided by the multimedia viewers may be directly integrated into the application program executing the presentation canvas 104.

[0040] In one embodiment, each of the content previews 120-128 is embodied in a low resolution image, such as a mipmap. The low resolution image minimizes the amount of data held in memory at a given time. This enables larger portions of the presentation canvas 104 and multiple content previews to be efficiently displayed. When a user selects one of the content previews 120-128 to access the underlying multimedia file or zooms into one of the content previews 120-128, the application program may call a higher resolution image or the multimedia file into memory and swap the higher resolution image or the multimedia file with the content previews in memory at that time. For larger multimedia files, the application program may call into memory only the relevant portion of the multimedia file that is currently displayed, thereby enabling the display of large text documents, spreadsheets, diagrams, charts, and the like. The application program may seamlessly transition between the low resolution images and the multimedia files in order to provide smooth zooming and panning of the presentation canvas 104 and the multimedia files inserted thereon.

[0041] In one embodiment, the presentation canvas 104 operates in one or more different modes. For example, the presentation canvas 104 may operate in a build mode, an annotate mode, and a present mode. The build mode may represent a mode in which documents, text, multimedia files, hyperlinks, nested workspaces, and other objects can be inserted into the presentation canvas 104. The annotate mode may represent a mode in which the presenter or another user can annotate the presentation canvas 104 with comments or other annotations. The present mode may represent a mode in which the multimedia files, hyperlinks, and nested workspaces inserted into the presentation canvas can be accessed and displayed during a presentation.

[0042] Turning now to FIG. 4A, an exemplary configuration of the user interface 400 utilized within the presentation canvas 104 is shown, in accordance with one embodiment. The user interface 400 includes a navigation menu 402 and workspace 404. The navigation menu 402 may include a variety of selectable options that a user can utilize to interact with the workspace 404. As discussed above, in one embodiment the workspace 404 comprises virtually infinite space onto which documents, text, multimedia files, hyperlinks, nested workspaces, and other objects may be placed. In particular, the user may utilize the navigation menu 402 to insert multimedia files, hyperlinks, and nested workspaces onto the workspace 404. It should be appreciated that the navigation menu 402 may be positioned within the user interface 400 in a variety of other ways, as contemplated by those skilled in the art. Also, the navigation menu 402 may be hidden until the user chooses to access it.

[0043] Turning now to FIG. 4B, a more detailed view of the navigation menu 402 is shown, in accordance with one embodiment. The navigation menu 402 includes a mode selection function 406, which includes a build mode 408, and an annotate mode 410, and a present mode 412. As illustrated in FIG. 4B, the build mode 408 has been selected. In one embodiment, the build mode 408 refers to a mode in which multimedia files, hyperlinks, and nested workspaces can be inserted onto workspace 404. The annotate mode 410 refers to a mode in which annotations can be added to the workspace 404 to supplement the content previews displayed on the workspace 404. The present mode 412 refers to a mode in which the contents of the workspace 404 may be accessed for display during a presentation.

[0044] The navigation menu 402 further includes an insert menu 414, which when selected provides a number of different functions for inserting multimedia files, hyperlinks, and nested workspaces onto the workspace 404. In particular, the insert menu 414 includes a files function 416, a workspace function 418, a workspace label function 420, a text function 422, an image function 424, a video function 426, and a website function 428. The functions 416-428 illustrated in FIG. 4B are merely exemplary and other functions for inserting multimedia files, hyperlinks, and nested workspaces onto the workspace 404 may be similarly utilized.

[0045] In one embodiment, the files function 416 enables a user to insert one or more presentation files into the workspace 404 via a file menu. For example, the user may utilize the files function 416 to insert presentation templates or previously-created presentation slides. The workspace function 418 enables the user to insert a nested workspace onto the workspace 404, and the workspace label function 420 enables the user to label the nested workspace. Nested workspaces are described in greater detail below with respect to FIG. 4C.

[0046] The text function 422 enables the user to insert one or more word processing files onto the workspace 404. The text function 422 may also enable the user to manually enter text onto the workspace 404. The image function 424 enables the user to insert one or more image files onto the workspace 404, and the video function 426 enables the user to insert one or video files onto workspace 404. In one embodiment, the text function 422, the image function 424, and the video function 426 include additional configuration functions to format and orient the inserted text, images, and videos, respectively. For example, the image function 424 may include configuration functions for sizing the displayed image or formatting the manner in which the image is displayed during a presentation. The website function 428 enables the user to enter a hyperlink.

[0047] In one embodiment, the navigation menu 402 includes a snapshot capture item 429 for capturing instances (referred to herein as “snapshots”) of the presentation canvas as displayed at a given time. For instance, the current zoom level and pan location may be recorded as a snapshot. In one embodiment, the snapshots can be ordered in a linear sequence and displayed in a similar manner as slides in conventional presentation applications. Each snapshot is essentially a predefined starting part that can be used during a presentation. In one embodiment, the snapshots are interactive in the same manner as directly interacting with the presentation canvas 104. For example, if a given snapshot shows the first nested workspace 144, then a user select the video content preview 120 via the snapshot to access the video file 106.

[0048] In an illustrative example, selection of the snapshot capture item 429 will cause a menu (not shown) to be displayed that includes a number of functions for creating and arranging the snapshots. When in the present mode 412, the user may utilize a back button 430 and a forward button 432 to navigate between previous snapshots and subsequent snapshots, respectively, in a linear sequence.

[0049] Turning now to FIG. 4C, a more detailed view of the workspace 404 is shown, in accordance with one embodiment. The illustrative workspace 404 shown in FIG. 4C includes a number of illustrative nested workspaces. In particular, the workspace 404 includes a first nested workspace 434, a second nested workspace 436, a third nested workspace 438, and a fourth nested workspace 440. Within the second nested workspace 436 is a fifth nested workspace 442 and a sixth nested workspace 444, and within the third nested workspace 438 is seventh nested workspace 446. Within the sixth nested workspace 444 is an eighth nested workspace 448.

[0050] As previously mentioned, the workspace function 418 may be selected to insert the nested workspaces 434-448. Likewise, the workspace label function 420 may be selected to provide labels for the nested workspaces 434-448. In one embodiment, each nested workspace 434-448 includes an outer label and an inner label. The outer label may be placed along a tab of the nested workspaces 434-448. The inner label may be placed within the nested workspaces 434-448. In one example, the first nested workspace 434 includes an outer label 450 stating “understand” and an inner label 452 stating “opportunity identification.” In another example, the second nested workspace 436 includes an outer label 454 that is blank, and the inner label 456 stating “label.”

[0051] Like the workspace 404, each of the nested workspaces 434-448 includes a virtually unlimited space in which a user can insert multimedia files, hyperlinks, and additional nested workspaces. The nested workspaces 434-448 may be moved, oriented, and resized in any suitable manner within the workspace 404. In one embodiment, selecting one of the nested workspaces 434-448 causes the selected nested workspace to enlarge on the screen. For example, clicking on the tab containing the outer label 450 may cause the first nested workspace 434 to enlarge, thereby enabling the user to better view the content previews and nested workspaces contained in the first nested workspace 434.

[0052] The nested workspaces 434-448 may be utilized to organize content previews and other nested workspaces. For example, video files may be inserted into a nested workspace labeled as “video,” and audio files may be inserted into a nested workspace labeled as “audio.” Additional nested workspaces may be included to further organize the inserted video and audio files. For example, the nested workspace labeled “video” may include a nested workspace labeled “advertising” for promotional videos and another nested workspace labeled “training” for employee training videos. During a presentation, a user can seamlessly and intuitively access a variety of multimedia files and hyperlinks during a presentation by navigating the nested workspaces 434-448 and utilizing the zooming and panning functionality.

[0053] Referring now to FIGS. 5A and 5B, additional details will be provided regarding the embodiments presented herein for providing a non-linear presentation canvas, such as the presentation canvas 104. In particular, FIG. 5A is a flow diagram illustrating aspects of one method provided herein for interacting with the presentation canvas 104 during the build mode 408. Further, FIG. 5B is a flow diagram illustrating aspects of one method provided herein for interacting with the presentation canvas 104 during the present mode 412.

[0054] It should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system.
