System and method of annotating presentation timeline with questions, comments and notes using simple user inputs in mobile devices

Abstract

A system and method for presentation timeline annotation are provided. The system permits an audience member to interact with the presentation using simple inputs, such as key presses on desktop computers or gestures on a mobile device for example, to mark a segment of the presentation timeline with various interactive annotation capabilities including, for example a question, a comment, a rating or a large number of other interactive annotation capabilities.

Description

FIELD

The disclosure relates to web-based content presentations, where presentations can be broadly divided into three categories including live or recorded interactive webcasting, podcasting (video or audio), and slideshows. The disclosure more specifically relates to a system and method for allow an audience member to provide interactive annotations to a presentation timeline using simple inputs.

BACKGROUND

Due to the lack of currently available non-interruptive question and answer (Q&A) (i.e., the presenter speaking in a large event or meeting can't stop to view or answer every question while presenting), asking questions, commenting and note taking during presentations to large audiences requires audience members to regularly break-out of the presentation to do trivial tasks like asking questions or writing a comment or note. Very often these tasks are performed through widgets and forms, which in turn prohibit a uniform experience for the audiences.

From the point of view of archiving of audience interactions and feedback—there exists no convenient ways for the audience to quickly go back to the segment of a presentation where a question was asked or a comment was written. Furthermore, for the presenter of a presentation to an audience, there is no convenient way to identify and address segments of the presentation that raised more questions, concerns or feedback from the audiences.

In the current state of the art presentation systems, audience interactions such as question & answering, commenting, reviews and rating are enabled through third-party plugins or custom widgets that are embedded in the web page containing presentation video, audio and slides. For example, there exists popular social commenting plugins from Facebook and Disqus. These currently available solutions are mostly general purpose solutions that have no special concerns for presentation experience or flow. For example—Facebook's commenting plugin can be embedded into any web page usually at the bottom (or side) of main content. New comments and questions get added to the bottom of the main thread or somewhere in the middle of sub-threads. In the process, synchronization of presentation timeline and audience interactions is lost.

DETAILED DESCRIPTION OF ONE OR MORE EMBODIMENTS

The disclosure is particularly applicable to a system and method for annotating presentation timelines in a web casting system and it is in this context that the disclosure will be described. It will be appreciated, however, that the system and method has greater utility because it may be implemented in other manners that are within the scope of the disclosure and may be used for other presentation systems in which the annotation of the presentation timelines is desirable. Furthermore, the system and method for annotating presentation timelines also may be used with audience participation widgets in which the presence, invocation, reuse and overall design and experience of using these widgets alongside a presentation may be changed drastically. Now, a disclosure of an on-line web-based presentation system is provided wherein the on-line web-based presentation system may include the system and method for presentation timeline annotation.

FIG. 1 is a diagram illustrating a method 20 for asset acquisition for online presentation event system. As shown, an audio/video or audio data source 22 is edited in step 24 if necessary or is automatically captured. In step 26, the data source 22 is encoded. Alternatively, an automated phone-based recording source 28 is encoded in step 30. The encoded data may then be stored in a media database 32, such as in a real media format 32a and/or a windows media format 32b. In this manner, a data source/piece of media is prepared for distribution using an event system, an example of which is shown in FIG. 2.

FIG. 2 is a diagram illustrating an event system 40 into which the presentation timeline annotation apparatus may be incorporated. The event system 40 may comprise an asset acquisition and event management portion 42, a database portion 44 and a distribution portion 46 wherein a piece of media/content 48 is input into the event system 40 in order to distribute that content/piece of media during the event. Generally, each element of the event system being described is implemented in software wherein each portion may be one or more software modules and each software modules may be a plurality of computer instructions being executed to perform a particular function/operation of the system. Each element of the system may thus be implemented as one or more computer resources, such as typical personal computers, servers or workstations that have one or more processors, persistent storage devices and memory with sufficient computing power in order to store and execute the software modules that form the frame event system in accordance with the invention. The event system may generate an event that is provided to one or more event clients 52 wherein each client is a computing resource, such as a personal computer, workstation, cellular phone, personal digital assistant, wireless email device, telephone, etc. with sufficient computing power to execute the event client located on the client wherein the client communicates with the event system over a wired or wireless connection.

In more detail, the asset acquisition and event management portion 42 may further comprise an asset acquisition portion 42a and an event management portion 42b wherein the asset acquisition portion performs one or more of the following functions: recording of the piece of media/content, editing of the piece of media/content, encoding of the piece of media/content and asset tagging. The event manager module 42b further comprises an asset manager module 50a, an event manager module 50b, a presentation manager module 50c and an encoder controller 50d. The asset manager module 50a, prior to an event, imports/exports content/pieces of media into/from a library of media as needed and manages the assets for each event presentation. The event manager module 50b may perform actions/function prior to and after an event. Prior to a particular event, the event manager module may reserve the event in the system (both resources and access points), set-up an event console which a user interacts with to manage the event and then send messages to each recipient of the upcoming event with the details of how to access/operate the event. After a particular event, the event manager module 50b may permit a user to import an old event presentation into the system in order to re-use one or more pieces of the old event presentation. The presentation manager module 50c, during a particular event presentation, generates an event file with the slides of the event presentation, URLs and polls to an encoder controller to distribute the particular event presentation to the users. The encoder controller 50d encodes the event presentation stream to one or more distribution server 54 that distributes the event presentation to the users.

As shown in FIG. 2, the database 44 may include data about each event, including the clients to which the event is being provided and the media associated with the event, one or more event users, the display of the particular event, the assets associated with the event, the metrics for the event and other event data. In combination with this data in the database for a particular event, operations and commands from the event manager module 42b are downloaded to the distribution servers 54 that distribute each event to each client 52 for the particular event over a distribution network 56. As shown, the event/presentation may be distributed to one or more different clients 52 that use one or more different methods to access the event. The clients 52 may include a client that downloads the presentation and then views the presentation offline.

FIG. 3 illustrates more details of the event system shown in FIG. 2. The event system may include a web server portion 60, an application server portion 62 and the database portion 40 (with the database 44) shown in FIG. 2. Each of these portions may be implemented as one or more computer resources with sufficient computing resources to implement the functions described below. In a preferred embodiment, each portion may be implemented as one or more well-known server computers. The web server portion 60 may further comprise one or more servlets 64 and a web container portion 66 which are both behind a typical firewall 68. In a preferred embodiment of the invention, the servlets reside on a BEA Weblogic system which is commercially available and may include an event registration servlet, an event manager module servlet, a presentation manager module servlet and an encoder controller servlet that correspond to the event manager module 50b, presentation manager module 50c and encoder controller 50c shown in FIG. 2. Each of these servlets implement the functions and operations described above for the respective portions of the system wherein each servlet is a plurality of lines of computer code executed on a computing resource with sufficient computing power and memory to execute the operations. The servlets may communicate with the application server portion 62 using well-known protocols such as, in a preferred embodiment, the well-known remote method invocation (RMI) protocol. The servlets may also communicate with the web container portion 66 which is preferable implemented using an well-known Apache/Weblogic system. The web container portion 66 generates a user interface, preferably using Perl, Active Server Page (ASP), HTML, XML/XSL, Java Applet, Javascript and Java Server Pages (JSPs.) The web container portion 66 may thus generate a user interface for each client and the presentation manager module user interface. The user interface generated by the web container portion 66 may be output to the clients of the system through the firewall as well as to an application demo server 68 that permits a demo of any presentation to be provided.

The application server portion 62 may preferably be implemented using an Enterprise JavaBeans (EJBs) container implemented using a BEA Weblogic product that is commercially sold. The application server management portion 62 may be known as middleware and may include a media metric manager 70a, a chat manager 70b, a media URL manager 70c, an event manager 70d, a presentation manager 70e and an event administration manager 70f which may each be software applications performed the specified management operations. The application server portion 62 communicates with the database 44 using a protocol, such as the well-known Java Database Connectivity (JDBC) protocol in a preferred embodiment of the invention. The database 44 may preferably be implemented using an Oracle 8/9 database product that is commercially available. As shown, the database 44 may include media data including URL data, slide data, poll data and document data. The database 44 may further include metric data, event data and chat data wherein the event data may further preferably include administration data, configuration data and profile data.

FIG. 4 is a diagram illustrating more details of the event database 44 in FIG. 3. As shown in FIG. 4, the database may generate data that is used to implement a function to reserve an event, to configure an event, present an event, for registration, for the lobby for the event console, for reporting and for archiving an event. The database may include asset data 44a that may be provided to the asset manager module 50a, metrics data 44b that is provided to a metric module 72, event data 44c that is provided to the event manager module 50b, presentation data 44d that is provided to the presentation manager module 50c, event user data 44e that is provided to an event registration module 80, display element data 44f that is provided to an event consoles module 76 and email notification data 44g that is provided to an email alerts module 74. The database may also store data that is used by a reporting module 78 to generate reports about the events and presentations provided by the system. The database may also store data that is used by a syndication module 82 to syndicate and replicate existing presentations.

FIG. 5 is a diagram illustrating an event center 90 that may be utilized by one or more users 92 that are presented with a presentation by the system and one or more presenters 94 who utilize the system to present presentations to the users 92. The users 92 may interact with a registration and lobby modules 80 that permit the users to register with the system and schedule a presentation to view. In response to a successful registration, the user may be presented with a player page 96, such as a web page provided to a client computer of the user, that provides the audio and visual data for the presentation, slides, polls and URLs for the presentation, chat sessions and question and answers for a particular presentation. The data in the player page 96 is provided by the web server 60, the media server 54 and a chat server 98 that provides the chat functionality for a presentation. The presentation data for a live event presentation is provided to the servers 54, 60 and 98 by the presentation manager module 50c. The presenters 94 may utilize the event manager module 50b to reserve an event and/or configure an event. Once the event is reserve and configured, the presentation data is forwarded to the presentation manager module 50c.

FIG. 6 is a diagram illustrating an example of an online presentation client 100 that may incorporate the presentation timeline annotation apparatus. The event client 100 may be implemented as a personal computer, workstation, PDA, cellular phone and the like with sufficient computing power to implement the functions of the client as described below. In the example shown in FIG. 6, the event client may be a typical personal computer that may further comprise a display unit 102, such as a CRT or liquid crystal display or the like, a chassis 104 and one or more input/output devices 106 that permit a user to interact with the client 100, such as, for example, a keyboard 106a and a mouse 106b. The chassis 104 may further include one or more processors 108, a persistent storage device 110, such as a hard disk drive, optical disk drive. tape drive, etc., and a memory 112, such as SRAM, DRAM or flash memory. In a preferred embodiment, the client is implemented as one or more pieces of software stored in the persistent storage device 110 and then loaded into the memory 112 to be executed by the processor(s) 108. The memory may further include an operating system 114, such as Windows, and a typical browser application 116, such as Microsoft Internet Explorer, Mozilla Firefox or Netscape Navigator and an event console module 118 (including a slide, polls, survey, URL, Q&A) that operates within the browser application. The client side of the system/apparatus is implemented as HTML and Javascript code that is downloaded/streamed to the client 100 during/prior to each presentation so that the synchronization of the assets does not require separate client software downloaded to the client.

FIG. 7 illustrates a set of media unit components and client components that implement a method for reconstructing the timeline of a presentation. To implement the method for reconstructing the timeline of a presentation, a set of media unit components (that may be implemented on one or more server computers) and a set of client 100 components are used that interact with each other. In the method, the audio/video stream must anchor the timeline, from the viewer's point of view. If media playback is delayed on the client-side due to network latency, if the viewer pauses the player for some duration and then resumes playback, or if playback is temporarily paused by the player to allow buffering, then all other presentational events in the webcast must also be offset in time by the same amount which is the goal of the timeline reconstruction method.

The presentation manager 50c, web server/application server/database 98 and the streaming media servers 54 described above are part of the process. In addition, a synchronization unit 122, that may be implemented as one or more server computers, participates the process. In particular, as the presenter's audio and video data is encoded (by an encoder that is part of the media unit) and broadcast (by the media server 54), the synchronization unit 122, acting as if it is client software that receives the media stream, receives the encoded media stream and demultiplexes it using a demultiplexer 124 that is part of the synchronization unit 122. As the raw media stream data is demuxed, timestamps are extracted by a timestamp extractor unit 126 of the synchronization unit 122. The timestamps may be a start time and/or end time for a particular portion of the stream and the like. The timestamps are captured together with informational markers into the stream data—enough information so that the timestamp and its association with a particular piece of media data can be reconstructed and reassociated independently later on the client.

In the system, anything that is part of a presentation that is synchronized with the audio and video may have timestamps. Examples of timecoded serial data may include, but is not limited to, slide/powerpoint flips, captions, animations like a moving virtual pointer, any background/auxiliary information that should be displayed at specific times during the presentation, links to other resources that should be displayed at specific times, for example linking to a participation certificate after viewing time has been reached and polls or surveys that should be displayed at specific times.

After the timestamps are extracted, the stream is remuxed using a multiplexer 128 in the synchronization unit 122 and transmitted to each client who is viewing the particular presentation. Optionally at this step, the media data can additionally be transcoded using a transcoder 127 in the synchronization unit 122 into another format that is supported on the client device. While the re-encoded media stream is being sent to the client, the timeline synchronization information, media data association, and local server time are published (using a timeline publishing unit 129 associated with the synchronization unit 122) in a place and format suitable for retrieval separately by client software.

At a suitable time on the client, when it requests the stream data, it separately also obtains the corresponding timestamp information that was extracted from the media stream previously that corresponds to the current audio/video data, by retrieving it from the location where it was published. Then at an appropriate time on the client side—when the media data has finished buffering and begins playback—the client captures, and saves for later use, the current local device time.

The local device time that is captured at the right moment, will be different than the timestamp captured on the server during in the previous steps, but the two different times will correspond to the same point on the presentation timeline. Those two timestamps and the difference between them, together with the time offset delay calculated from the transmission latency between client and server, can be used to determine the correct time delay to use when rendering all other presentational events of the webcast, such as slide transitions, so that they are rendered on the client in the same time positions as the speaker intends when the presentation is produced.

On each client that is participating in the presentation, the client reconstructs the event timelines by: 1) retrieving the presentation events from the web server/application server/database 98 of the media unit; 2) retrieves the media time data generated by the timeline publishing unit 129; 3) retrieves the re-encoded media stream; 4) generates the reconstruction presentation timeline as described above; and 5) synchronizes with the media player events in the browser 118 (such as the media player component, the question and answer/chat channel, any slides and any other presentation items). The event console manager on each audience member device may be implemented as a plurality of lines of computer code executed by the computer that perform the steps above.

FIG. 8 illustrates an example of an implementation of an event console manager/client 100 that is part of the event presentation system. The client performs a presentation preparation process 140 in which the client downloads the media data, retrieves non-media presentation assets and retrieves the sync data. During a reconstruct timeline process 142, the client reconstructs the timeline of the presentation based on the media data, the non-media presentation assets and the sync data. Thus, for example as shown in FIG. 8, the timing of the slides, captions and polls of the presentation are determined as shown pictorially in FIG. 8. Once the timeline is reconstructed, the client reconstructs the presentation (144) for one or more browsers and the presentation playback begins (146).

FIG. 9 illustrates more details of the presentation timeline annotation system 900. The presentation timeline annotation system 900 may further comprise one or more components on the backend side 98, 122 and one or more components on the client side 100. The components on the backend side and the client side may interact with each other over a link 901 to implement the presentation timeline annotation system. The link 901 may be a wired or wireless link, such as the Internet, a computer network, a wireless computer network, a cellular data network and the like.

The backend components may include a backend annotation manager 902 and the presentation database 44 described above and the client side components may include an annotation component 920 and a presentation component 910. Each of the components shown in FIG. 9 may be implemented in hardware or software or a combination of hardware and software. In one embodiment, each of the components may be a plurality of lines of computer code that may be stored in a memory of the backend or client device and then executed by a processor of the backend or client device. The annotation component 920 of the client side may perform the annotation operations and functions described below in more detail while the presentation component 910 may generate the user interface of the presentation and display the presentation to each audience member such as is shown, for example, in FIGS. 7 and 11.

The backend annotation manager 902 and a client annotation manager 924 (that is part of the annotation component 920 on the client) each may control the annotations made to the presentation. For example, either of the annotation managers 902, 924 (or both of them in some embodiments) may allow a user (the presenter or producer of the presentation or the audience member that receives the presentation) to set one or more settings of the presentation timeline annotation system. For example, each or both of the annotation managers 902, 924 may allow a user to configure one or more annotation selectors that trigger (for an audience member) the marking of a segment of the presentation with an interactive annotation wherein the interaction annotation may include, for example, a question, an answer, a comment, a note, a review or a rating of the presentation. The one or more annotation selectors may be key presses, such as for a personal computer, desktop computer, tablet computer, etc. or a gesture, such as for smartphone devices, tablet computer and the like. For example, the gesture may be a hand movement on a Samsung Galaxy smartphone device or the movement of a device that indicates user intent, such as a shake motion. In some embodiments, the one or more annotation selectors may be preconfigured using the annotation manager 902 by the content presenter or producer.

A non-limiting example of different key presses that may be used as the one or more annotation selectors are shown in Table 1 below.

TABLE 1
Sample Key/Key Combination Action
Q                          Mark current segment with a question
Shift + Q                  Mark current segment with a question
                           and add a question
N                          Mark current segment with a note
Shift + N                  Mark current segment with a note and
                           add a text note
R                          Mark current segment with a review
Shift + R                  Mark current segment with a review
                           and add a review

As shown in FIG. 9, the annotation component 920 also may include an annotation event handler 928 and an annotation user interface (UI) generator 930. The annotation event handler 928 may perform one or more functions to implement the presentation timeline annotation method as shown in FIG. 10 while the annotation user interface generator 930 may generate the annotation user interface elements displayed to the user (examples of which are shown in FIGS. 11-14) or as shown in FIG. 7 when the annotations are used in conjunction with a user interface widget. For example, FIG. 14 illustrates an example of the presentation display and the annotation display that may be displayed to the user.

FIG. 10 illustrates a method for presentation timeline annotation 1100 that may be implemented, for example, using the backend and client side components shown in FIG. 9. In the method, a client side component, such as the annotation event handler component of the annotation component, may listen/detect the one or more annotation selector events (1002) and delegate the relevant annotation selector events to the appropriate annotation event handler. If no annotation selector events occurs, then the method loops back to the start. If an annotation selector events occurs, the annotation event handler may determine a time reference, such as a current timestamp or slide number of video/audio and slideshow, respectively, at which the annotation selector event occurred (1004.) The time reference is an important point of reference, which is maintained throughout the lifetime of content. The time reference identifies a point in the presentation at which an audience member wants to make an annotation to the presentation timeline.

The annotation event handler also may, based on the time reference of the annotation event, create a custom annotation object, such as using JavaScript for example, with annotation type and time reference as two primary properties. Everything in a JavaScript world are objects, in its simplest form a pair of curly braces represents a JavaScript object, e.g. { }. There are several ways to create, manipulate and maintain such objects. Various types of properties and methods can be added to these objects, e.g. var annotationObject={‘annotationName’: ‘Webcast 101’, ‘annotationTimestamp’: 1381179374, ‘annotationCreator’: ‘John Appleseed’, ‘annotationType’: ‘Q&A’}; Here annotationObject is created upon user interaction and it can be transferred across servers, stored in databases and dispatched to other clients.

The annotation event handler also may communicate the annotation object to the presentation database 44 (1006) using a protocol, such as a simple client-server communication protocol. The communication of the annotation object for each annotation event for each audience member allows the annotations to be delivered to each audience member of the presentation. For example, in one implementation, the created annotation object may be delegated to a next client-side module (for a particular audience member) where view of the annotation may be generated (1008), styling is added and the object itself is added to the annotation timeline on the given time reference point (an example of which is shown in FIGS. 12-13). Thus, each audience member for the presentation can see the annotations of the other audience members.

Two examples of an annotation user interface element 1200 are shown. FIG. 12 shows an example of a presentation timeline annotation user interface element for a video presentation element while FIG. 13 shows an example of a presentation timeline annotation user interface element for a slideshow presentation element. As shown in both Figures, the presentation timeline annotation user interface element may include an annotation indicator element 1202 that shows a location in the presentation at which one or more annotations occurred as well as the different types of annotations at each point in the presentation. For example, as shown in FIG. 12, there are two questions (indicated by Q(2)) and five comments (indicated by C(5)) ten minutes into the exemplary 30 minute video presentation. In FIG. 13, there are fifteen questions (indicated by Q(15)) and no comments (indicated by C(0)) at slide 10 of 30 slides of the exemplary slideshow presentation. As shown in these figures, the presentation timeline annotations are shown at the same time or in-line with the presentation so that the audience member is able to interact with the presentation while continuing to be engaged by the presentation.

In some embodiments, the dimensions of the presentation annotation timeline may be proportional to the duration or length of presentation. For example, for video/audio content, the system may have a one-to-one mapping of content duration and annotation timeline dimensions. For slideshows, for example, the system may have a control where its behavior and presentation is similar to HTML5 video player control.

In each user interface displayed to each audience member (such as that shown in FIGS. 12-14), the audience member can select an annotation in the timeline, such as by hovering over or clicking on the annotation, and an element, such as a text bubble, may be displayed such as is shown in FIGS. 12-13. The text-bubble may show the type and count of the audience member's interactions possibly showing interactions from other audiences and presenter. At any given point on the timeline, there could be zero or more annotations, where each annotation can be created by different users. Also, each annotation belongs to one of the supported annotation types such as Questions (Q), Answers (A), Rating (R) or Comment (C). Text-bubble is used to show type and count of annotation. For example, a timestamp containing 4 questions, 6 answers, 8 ratings and 0 comment can be displayed as Q(4) A(6) R(8) C(0). If an audience member selects the element, such as by clicking the text-bubble or double clicking the annotation mark, the user interface may present the audience member with the options to further interact with the annotation or open a specific widget from the dock etc. Continuing from above example of Q(4) A(6) R(8) C(0), a user could click on the ‘Q’ to open a widget containing 4 questions and a form to add new question.

The system of presentation timeline annotation also may be configured to support unary task only such as note taking. Thus, an audience member is able to mark a segment with notes and later have those notes emailed as a PDF or added to video as closed-caption.

While the foregoing has been with reference to a particular embodiment of the invention, it will be appreciated by those skilled in the art that changes in this embodiment may be made without departing from the principles and spirit of the disclosure, the scope of which is defined by the appended claims.
