Description
Background
[0001] Collaborators such as software development teams, interest groups, and research workgroups are often geographically scattered and span many time-zones. When there is at least some window of overlap in the normal working hours of distant collaborators, synchronous real-time fact-to-face video conference or telepresence communication can be scheduled within that window. When such a window does not exist and synchronous communication is not practical, the quality of communication in a group often degrades. Along with the lack of true conversation, various cues and signals available in face-to-face interaction may also be absent.
[0002] Asynchronous communication tools such as email and discussion boards help dispersed teams work together more effectively. However, some communication nuance is not possible with text-based tools. This may explain why studied communication patterns of temporally distributed teams indicate that members often try to find ways to interact synchronously, despite time zone differences of eight hours or more. Previous communication tools have not provided the benefits of synchronous real-time communication in an asynchronous format.
[0003] Described below are thread-based visualization tools to manage asynchronous video conversations.

Detailed Description
Overview
[0014] FIG. 1 shows a threaded video messaging system. Components of the system will be explained first, followed by discussion of the flow of an example use of the system.
[0015] The video messaging system centers around a threaded video message view 100, which may be presented in an application window, a web page, or the like, and displayed on a display 102. The threaded video message view 100 displays message icons 104 that represent respective video messages stored in a data store 106, for example, in one or more video message tables 108. A stored video message includes at least playable video data (a video clip) and any associated data, in particular, message data such as an identifier of an author or sender, a date and time the message was sent or added, metadata, and so forth. Other tables and data may be stored in data store 106, for instance, a conversation table with records for respective different conversations, a table with records associating video messages with particular conversations (in FIG. 1 , only one conversation is shown in message view 100), a table of users indexed by user identifiers, etc. A links table 110 may contain records associating video messages; a record may have a first field with a first message identifier and a second field with a second message identifier, thus indicating that the two referenced messages are linked or threaded together.
[0016] Considered as a whole, the data in the data store 106 stores hierarchies of video message or video clips (see message hierarchy 111 corresponding to view 100A), where each hierarchy is a different conversation, thread, group of topically related messages, etc. Given a particular conversation or thread, the thread engine 114 analyzes links 110 and video messages 108 to generate a hierarchy data structure. From this message or video clip hierarchy, a corresponding hierarchical video message view can be generated. Such a hierarchy may have a visual link 112 or line—displayed in the video message view 100—which corresponds to a link record in links table 110 that links two video messages corresponding to the message icons 104 connected by the visual link 112 (note that lines may be curved, straight, etc.). Additional details for implementing messaging in general are available elsewhere.
[0017] A thread engine 114 may maintain messaging and threading data in the data store 106. Threading may be driven by new video messages; new messages are threaded in as they are added to a conversation. Threading, however, need not be based on messaging between users, and while video messages are discussed, video clips may be threaded without the need for transmitting messages. Nor is there any requirement that video messages be submitted in reply to a video message of another user; in one embodiment any user (possibly only members of a defined group) can submit a video message anywhere. Furthermore, a video message can be inserted or threaded to any existing video message; there is no requirement that a reply be directed to a “leaf” message. Video messages can be created and threaded into a conversation manually or automatically based on content analysis (analysis of speakers in video data, analysis of associated metadata, etc.). A video blog type of view can be implemented where a single user continually adds video messages to their own video message threads.
[0018] Returning to threaded video message view 100, as mentioned, a video message is represented by message icon 104, which may be a thumbnail of a frame from the video data of the corresponding video message. In one embodiment, the threaded view of message icons 104 corresponds to a particular conversation selected by a user (see selector element 260 in FIG. 5 ). The message icons 104 may be laid out in different ways, for example, according to user, and/or time, semantic proximity, etc., but nonetheless includes lines or other graphics that indication connections between linked video messages, i.e., the view shows message threads. Hovering a pointer over a message icon 104 may trigger display of metadata about the corresponding video message and/or display of interactive interface elements (e.g., the various buttons and controls described herein).
[0019] The threaded video message view 100 may have various user interface elements to allow the user to input commands and invoke operations. In one embodiment, a current navigation context is maintained, which includes, for example, the current conversation, a video message that is currently selected, etc. In another embodiment, navigation state is implicitly stored as the state of user interface elements that make up the view. To invoke operations, the user may use keyboard shortcuts, graphical user interface elements, and the like. In the example shown in FIG. 1 , an interface element 116 may have a playback button 118 and a reply button 120. Instances of the interface element 116 may be overlaid on each message icon 104 (activation of a button thereof will result in an operation on the corresponding video message), or a single instance may be displayed (activation of a button will operate on a currently selected video message).
[0020] Conceptually, the threaded video message view 100 may be thought of as a single media player and messaging application, but with the ability to manipulate threaded video message conversations shown in its window (e.g., threaded video message view 100), and with the ability to direct media and messaging operations to conversations and messages and threads thereof shown in its window or view. In other words, the interface may be viewed as a single specialized video message player within which video messages (viewed in threads) may be individually and directly (or in groups) played, responded to with a new video message, annotated, etc. In some implementations, with a single click or other form of input, a user can play or start a reply to a designated video clip or message.
[0021] Flow of how a user may respond to a video message is now explained. At step (i), a threaded view of a conversation is displayed. In the example, message icons 104 and currently selected message icon VMA represent corresponding video messages. The lines between the icons represent relationships between the video messages. At step (ii), input (e.g., “reply” input) is directed to the video message represented by icon VMA. The current message/icon may be set by either interacting with the icon directly (clicking it, clicking a button thereon, etc.), or by first designating the icon and then invoking a command which operates on the video message of the designated icon. In the present example, reply button 120 is activated, which triggers step (iii).
[0022] At step (iii), in direct response to the reply command directed to a particular video message/icon, a video capture operation begins. The video may be captured by a camera 122, a screen-capture tool, or a combination thereof. While or after the video is captured (of the user and/or content displayed on the user's display 102), the video is stored and associated with a new video message VMB. In a true messaging implementation, this may be similar to an email client generating a new email message when replying to a received email. Various data may be added to the new video clip or message VMB, such as the identity of the current user, the time the video message was generated, a subject or other information entered by the user, the identity of the current conversation, the identity of the video message being replied to (video message VMA), and so on.
[0023] At step (iv), the thread engine 114 receives the new video message VMB and threads the new video message, for example, adding a link record 124 to the links table 110 and storing the video message VMB in the video messages table 108. At step (v), the threaded video message view 100 is automatically redisplayed as view 100A, reflecting the new video message VMB; a message icon 104A is shown linked to the icon of video message VMA. If other users are running instances of the threaded video message view, their views may also be updated in due course. Furthermore, if other such users submit new video clips or messages in reply to the viewed clips or messages via their views, any views are similarly updated.
[0024] In one embodiment, the video messaging system is a client-server type system. The thread engine 114, which might act as a network service, receives messaging input from client applications (message view instances of different users) and sends to clients display data. A client renders the display data to display a threaded video message view. The display data may be high level semantic information about which messages/clips exist, how they are related, etc. The display data may be renderable data such as hypertext markup language or extensible markup language, information conveyed by a client-server protocol, low-level graphic elements, actual executable code (e.g., Java™ or .Net™ bytecode), etc. The client applications can update according to the display data, render or execute the display data, or otherwise use the display data to display their respective instances of the threaded video message view 100. If one client submits a new video message in its threaded video message view 100, the new video message eventually becomes viewable in its own view and the views of the other clients.
[0025] In another embodiment, the network functionality (communication between users, etc.) is handled by an email client, and the threaded video message view is a component of the email client for viewing and responding to threaded video messages. Underlying email functionality can be readily leveraged. In one embodiment, various pieces of data are stored in a cloud or server cluster and threaded video messaging is provided as a serviced that is accessed by users through a client interface such as a web browser or the like.
[0026] FIG. 2 shows a chronology of example video message exchanges. Users 150A, 150B, and 150C have terminals with respective cameras and displays, each at various times, displaying respective instances of threaded video message view 100. The activities of the users 150A, 150B, 150C are illustrated along respective timelines 152A, 152B, 152C. Letters “A” to “I” will be used to indicate both video messages and corresponding points in time. Initially, one of the users creates a new asynchronous video conversation. User 150A creates a first video message A at time A. Note that blocks 154 represent duration of messages. User 150B responds with message B via his or her instance of threaded video message view 100. User C, whose view has been updated to reflect messages A and B, interacts with a local icon of message A to direct a reply to video message A, resulting capture of video (screen or camera video) and new video message C. After time/message C, threaded video message view 100 shows icons A, B, C, and corresponding thread lines. This back-and-forth video messaging or posting continues up to time I. Again, a formal messaging system need not be used. Asynchronous video sharing can be performed with any system or service that allows users to view and post video clips.
[0027] FIG. 3 shows video messaging operations 170. The messaging operations 170 can be invoked as discussed above with reference to FIG. 1 . As described above, the user is able to directly interact with video messages or clips. The letters “A” to “C” in FIG. 3 represent users A, B, and C, respectively (the upper message icon 104 is an image of user A, who created and appears in the corresponding video message). Any operation may be directed to a particular video message/clip/icon. For example, user B can click a “reply” button on icon 104A and a reply video message is immediately started. A user may select a thread or path in the view (e.g., the sequence B-A, by selecting message B), and may invoke a play-thread operation that plays the video messages B and A (lower A in FIG. 3 ) in sequence as though a single clip of video. A user may invoke a play operation to play a single video message, for example, by clicking an icon or a “play” button on a message icon 104, which results in the video message being played, either in a larger pop-up window, or directly in the space of the icon, or in a separate display area. In sum, video messaging operations can be invoked with minimal or even single user inputs.
[0028] Asynchronous video communication may be supplemented by various messaging tools and features. For example, a user may be allowed to create in-line replies when playing a video message; the reply is linked not only to the clip being played, but also to a particular part of the clip. An impression feature may be provided by which video of a recipient playing back a video message is captured (either as a new message, or as data associated with the played-back video message), thus allowing a sender to later view a recipient's (or other viewer's) reaction. Reaction capturing may be explicitly requested with a video message, or a viewer may activate reaction-capture during playback. In one embodiment, a user composing a video message may include markers where feedback is desired, possibly leading to a prompt during playback for video or other form of feedback. A visual indicator such as a pencil icon may fade in and overlay the playing video and fade out when the marked period of desired feedback passes. Any feedback is associated with the time of the video message to which the feedback is directed. Signals about user impression can be captured and conveyed. For instance, features such as pitch, speaking time, amount of movement and agreement, etc., can be automatically analyzed and returned to the user in the form of user interface metadata.
[0029] FIG. 4 shows detail of a threaded video messaging interface. In this embodiment, a message icon 104 has an image, a reply button 120, a playback button 122, a screen capture checkbox 190, and a camera capture checkbox 192. Process 194 shows steps for replying to a video message. Starting with activation of reply button 122, a reply user interface element 195 is displayed. The reply user interface element 195 may be a display pane or window accompanying the threaded video message view 100. A slider element 196 may indicate how much video has been captured and may allow moving the current capture point. A start/pause button 198 may allow video capture to be started and paused. A screen capture view 200 may be displayed which shows live screen video as it is being captured, and a camera view 202 of video being captured by camera may also be displayed. If the screen capture checkbox 190 is selected, another interface element may be provided that allows the user to select a part of the screen to be captured, for instance, a selector to identify a window, or a frame tool 204 that can be moved and resized to frame an area of the screen to be captured, etc. As described above, when a video capture is finished, a corresponding video message is generated, stored/transmitted, and delivered or posted. If a video message contains screen-capture video, its corresponding message icon 104 may include a camera icon or other visual indication of the presence of screen video.
[0030] When composing a reply, or when composing a new video message, annotations may be added. For example, text annotations may be inserted at various points in a video clip. When played back, the annotations fade in for some duration and then fade out. Annotations may include hyperlinks and other forms of media. Graphic annotations may be overlaid on top of video, for instance, highlighted regions, lines/pointers, etc.
[0031] FIG. 5 shows another video messaging interface 250. A time-ordered thread view 252 shows message icons 104 in chronological order. Lines 254 and dates indicate when video messages represented by the message icons 104 were submitted. In addition, a play-thread button 254, a new-conversation button 256, and a reply button 258 are available. The play-branch button 254 causes a sequence of video messages in a currently selected thread or sub-thread to be played in sequence. The new-conversation button 256 creates a new threaded asynchronous video conversation (and appropriate entry in selector element 260). Note that the time-ordered thread view 252 shows messages of a currently selected conversation, which may be selected from among available conversations 259 using selector element 260. When a new conversation 259 is selected, the corresponding video messages are shown, threaded, in time-ordered thread view 252.
[0032] Different types of thread layouts may be used. For example, messages may be threaded and displayed according to implied links, such as relations between users. One approach is to automatically lay out message icons 104 based first on links between messages, and with placement of message icons otherwise driven by any of a variety of known algorithms for generating graph layouts.
[0033] In an embodiment where special client applications and a dedicated server are used, notifications of new video messages may be sent via email to corresponding recipients. Notifications may include information about the video message and a link to open the message. Screen capturing may be accompanied by only voice recording instead of camera-captured video, thus allowing a user to create a video message by narrating a screen-capture sequence. In yet another embodiment, messages of different media types are used, and a conversation thread visualization may include emails, instant messages, phone messages, and other message types besides video messages.
[0034] Given a large set of video messages, it may be helpful to include a search function to allow users to search for video messages to find particular content or quickly browse a conversation. Video editing features may be included to allow custom editing and composition of video content in a video message, inserting images or external clips, etc. Moreover, tagging of video messages by users may be implemented, as well as automatic detection of subjects in thread of messages. Analysis of text may be implemented with speech-to-text recognition software that translates video clips (audio) into text.
[0035] In other embodiments, video messages are post-processed to extract additional information that is collected and indexed for searching or other uses. For example, keywords are extracted from text of the messages and/or from text generated by speech-to-text processing of audio data of the messages. In another embodiment video frames are analyzed to extract information about the video such as scene information, recognized faces, etc. Where participants are expected to speak different languages, language translation may also be used to allow cross-language searching, indexing, etc. In another embodiment, the video of a message is analyzed to identify a key scene icon to be used as the icon representing the message (rather than just using the first frame of the video). A search interface may be enhanced by presenting such icons with keywords extracted from the audio or otherwise obtained. Similar approaches and presentation of icons can also be used for managing threads or other tasks.
Conclusion
[0036] FIG. 6 shows an example computer 270. Computer 270 may have a processor 272, storage 274, and a display 276. The storage 274 may include computer readable storage media and memory. Embodiments and features discussed above can be realized in the form of information stored in such volatile or non-volatile computer or device readable media. This is deemed to include at least media such as optical storage (e.g., compact-disk read-only memory (CD-ROM)), magnetic media, flash read-only memory (ROM), or any current or future means of storing digital information. The stored information can be in the form of machine executable instructions (e.g., compiled executable binary code), source code, bytecode, or any other information that can be used to enable or configure computing devices to perform the various embodiments discussed above. This is also deemed to include at least volatile memory such as random-access memory (RAM) and/or virtual memory storing information such as central processing unit (CPU) instructions during execution of a program carrying out an embodiment, as well as non-volatile media storing information that allows a program or executable to be loaded and executed. The embodiments and features can be performed on any type of computing device, including portable devices, workstations, servers, mobile wireless devices, and so on.
