## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATION
The present patent application relies upon, claims the benefit of priority from, and is a continuation-in-part of U.S. patent application Ser. No. 14/052,532 filed on Oct. 11, 2013, the entire disclosure of which is incorporated by reference herein.


BACKGROUND OF THE INVENTION
1. Technical Field
The disclosed embodiments relate in general to techniques for enabling collaboration between individuals and, more specifically, to systems and methods for peripheral awareness of, and nominal interaction with, a remote meeting using a wearable device.
2. Description of the Related Art
Meetings, once the exclusive domain of offices and boardrooms, are becoming increasingly distributed across space, time, and devices. Such distributed meetings primarily involve groups or sets of individuals communicating from a laptop, desktop or phone-based setting where they have access to the technical infrastructure needed to communicate and share information. However, meeting participants cannot easily maintain awareness of these meetings if they are traveling, commuting, or located off-site (for example, in a waiting room at a doctor's office). Thus, in order for distributed meetings to be successful, the way that meeting participants and their shared files, screens, and other materials are represented must adapt to each participant's individual context.
Accordingly, as would be appreciated by persons of ordinary skill in the art, a lightweight, unobtrusive tool for enabling an individual to participate in an ongoing distributed meeting would be highly desirable.

DETAILED DESCRIPTION
In the following detailed description, reference will be made to the accompanying drawing(s), in which identical functional elements are designated with like numerals. The aforementioned accompanying drawings show by way of illustration, and not by way of limitation, specific embodiments and implementations consistent with principles of the present invention. These implementations are described in sufficient detail to enable those skilled in the art to practice the invention and it is to be understood that other implementations may be utilized and that structural changes and/or substitutions of various elements may be made without departing from the scope and spirit of present invention. The following detailed description is, therefore, not to be construed in a limited sense. Additionally, the various embodiments of the invention as described may be implemented in the form of a software running on a general purpose computer, in the form of a specialized hardware, or combination of software and hardware.
In accordance with one aspect of the embodiments described herein there are provided a system and associated method that allow meeting participants to maintain a basic awareness of the audio and visual content of a meeting using a wearable device, such as a smartwatch, well known to persons of ordinary skill in the art. Embodiments of the described system and method also provide essential interaction mechanisms such that the remote, mobile users can interact with the distributed meeting without distracting them from their other tasks. In one embodiment, the described techniques provide an unobtrusive way for users to participate in ongoing distributed meetings using a smartwatch-based interface for a video conferencing application.
In one or more embodiments, the described solution uses the concept of keyframes. Keyframes are still screen captures of a participant's shared screen during meetings, which are stored for later reference. The use of the aforesaid keyframes, which are static image captures descriptive of the content of the participant's shared screen, quickly provides the user with an idea of the current state of the video stream(s) of the distributed meeting without the need to display the realtime video stream of the meeting. This results in saving the battery life of the user's wearable device.
FIGS. 1(a) and 1(b) illustrate two exemplary embodiments of a system for enabling a distributed meeting of participants with at least one participant connecting to the meeting using a wearable device such as a smartwatch. An exemplary system 100 illustrated in FIG. 1(a) incorporates a central server 101, which is communicatively connected, via a computer network, with computing systems 102, 103 and 104 of the distributed meeting participants. In one or more embodiments, the data connections are implemented using HTTP protocol. The wearable device 105 worn by a meeting participant is also communicatively connected with the central server 101. In one embodiment, the computing systems 102, 103 and 104 of the meeting participants generate outgoing meeting streams, which may include, for example, video of participant's face, associated audio, chat text messages as well as content of participant's computer screen shared with the other meeting participants. In one embodiment, each of the participants' computer systems 102, 103 and 104 generates the keyframes based on the content of the participants outgoing meeting stream. The outgoing meeting streams and the generated keyframes are transmitted from each of the computing systems 102, 103 and 104 to the server 101. In another embodiment, the keyframes may be generated on the server 101 using the content of the received meeting streams.
In one or more embodiments, the audio, the generated keyframes and the chat messages (collectively 107) are transmitted from the central server 101 to the wearable device 105 via the network. In one or more embodiments, the generated keyframes and the chat messages are displayed to the user on the display of the wearable device 105. On the other hand, the received audio is transmitted (109) by the wearable device 105 to a headset 106 worn by the user using, for example, Bluetooth wireless protocol well known to persons of ordinary skill in the art. In one or more embodiments, using an inventive graphical user interface of the wearable device 105, the user is enabled to transmit chat text messages 108 back to the server 101.
In an alternative exemplary embodiment 110 illustrated in FIG. 1(b), a handheld device 111 is additionally provided. In the shown embodiment, the handheld device 111 communicates with both the central server 101 and the wearable device 105. The communication with the central server 101 may be provided using a cellular or WIFI data connection, while the communication with the wearable device 105 may be performed using Bluetooth or WIFI data connection. In one embodiment, the aforesaid audio, the generated keyframes and the chat messages (collectively 107) are first transmitted from the central server 101 to the handheld device 111, such as a smartphone. The handheld device 111, in turn, transmits the meeting audio 109 to the headset 106 worn by the user using, for example, Bluetooth wireless protocol or a wired connection, and the generated keyframes and the chat messages to the wearable device 105 for display to the user. In one or more embodiments, the handheld device 111 also handles joining the correct meeting by the user.
In one or more embodiments, the keyframes are generated on the server 101, and the parameters used in triggering keyframe generation are varied based on the type of content that the user is sharing at the particular time. In one embodiment, the keyframe generation system continually calculates and monitors the difference (distance) between the preceding and the subsequent video frames in the meeting video stream shared by each user and compares this difference (distance) with a predetermined threshold. When the threshold is exceeded, a new keyframe generation is automatically triggered. The aforesaid threshold may be different for different types of content.
For example, in one embodiment, when the user is sharing a standard Web camera (webcam) view, a certain predetermined level of change in a view (video stream) is required for a new keyframe to be generated in order to avoid identical non-relevant frames displaying e.g. a user's face. Thus, in case of video content of the user's face, the aforesaid threshold may be relatively high. On the other hand, when the meeting participant is sharing a slide show, any change in view will generate a new keyframe. Thus, the aforesaid keyframe generation threshold for slide show content may be very low.
In one or more embodiments, the generated keyframes are divided into user-specific (distributed meeting participant-specific) keyframe streams. These keyframe streams are furnished to the wearable device 105 and nay be selected by the meeting participant for viewing using the graphical user interface generated on the display of the wearable device 105. In one or more embodiments, the application executing on the wearable device 105 detects predetermined user gestures and switches between the aforesaid keyframe streams based on the detected predetermined user gestures. In one or more embodiments, the user gestures may be detected, for example, using touch-screen interface of the user-wearable device 105.
In one embodiment, a detected swiping up and down user gesture, which may be performed by the user with his or her finger or other suitable object, causes the wearable device 105 software application to change to a different user's stream and display the content (e.g. keyframes) of the so user-selected stream on the display device. On the other hand, in the same or different embodiment, the detected swiping left and right user gesture causes the wearable device 105 software application to cycle between key frames within a particular stream. Moreover, the detected double-tap user gesture zooms in and out of a keyframe. Finally, a zoomed-in frame can be panned around freely using a two-finger pinching gesture. As would be appreciated by persons of ordinary skill in the art, many other types of user gestures may be detected by the software application executing on the wearable device 105 and, therefore, the invention described herein is not limited to any specific user gestures.
Moreover, in one or more embodiments, the navigation between streams and keyframes may be accomplished using a speech recognition interface described in detail below. In this embodiment, the software application executing on the wearable device 105 detects specific spoken commands uttered by the user, such as, for example “next stream,” “previous stream,” “next frame,” “previous frame,” etc. Upon detection of a specific user-spoken command, the software application executing on the wearable device 105 executes the corresponding command. As would be appreciated by persons of ordinary skill in the art, many other types of user-spoken commands may be detected by the software application executing on the wearable device 105 and, therefore, the invention described herein is not limited to any specific spoken commands.
In one or more embodiments, whenever the latest keyframe in a meeting stream is being viewed and a new, more recent, keyframe is received by the wearable device 105 from the central server 101, the software application executing on the wearable device 105 automatically moves on to the new keyframe and displays this newly received keyframe to its user. This feature creates an automatic flow of keyframes that is up-to-date with what is being discussed in the distributed meeting, and allows the users to maintain awareness of the visual content of the meeting. In one or more embodiments, if the user currently interacts with a keyframe, such as by panning or zooming it, and a new keyframe is received from the server 101, the software application executing on the wearable device 105 does not immediately show the newly received keyframe to the user to avoid interrupting user's current activity in connection with the older keyframe.
In one or more embodiments, the software application executing on the wearable device 105 also contains a separate chat channel. The aforesaid chat channel allows users of the wearable device 105 to view chat (text) messages sent by other meeting participants and send their own messages to the meeting chat by using, for example, predefined yes/no responses provided by the graphical user interface. In another embodiment, the software application executing on the wearable device 105 incorporates a speech-to-text conversion functionality, which automatically converts user's speech to text messages sent over the aforesaid char channel to other distributed meeting participants. Software for speech to text conversion is well known to persons of ordinary skill in the art and any such software may be utilized without restricting the scope of the described invention.
FIG. 2 illustrates various exemplary embodiments of graphical user interface screens of a software application executing on the user-wearable device. In one or more embodiments, users of the wearable device 105 may access both the stream view and chat view from the application's graphical user interface main menu screen 201, see FIG. 2. In one or more embodiments, one or more of the subsequent screens include a panel 210 at the bottom of the screen to allow quick switching between views.
FIG. 2 further illustrates an exemplary embodiment of a stream view screen 202. Current or historical keyframes are being displayed to the user using this screen. The user is able to scroll to the next or previous keyframe using a horizontal sweeping gesture over the screen of the wearable device 105. FIG. 2 further illustrates an exemplary embodiment of a stream view screen 203 with the panel 210 opened. FIG. 2 further illustrates an exemplary embodiment of a chat view screen 204. FIG. 2 further illustrates an exemplary embodiment of a chat view screen 205 with panel 210 opened. As can be seen from FIG. 2, the chat view screen 205 includes buttons ‘Y’, ‘N’, ‘Rec’ and ‘Streams’ for speech-to-text (the ‘Rec’ button) and quick yes/no responses (′Y′ and ‘N’ buttons). In addition, the ‘Streams’ button enables the user to navigate to the stream view screen 203.
FIG. 2 further illustrates user swiping to another stream that is displaying a slide show, see screen 206. FIG. 2 further illustrates an exemplary embodiment of a graphical user interface screen 207 displaying a slide keyframe. FIG. 2 further illustrates an exemplary embodiment of a graphical user interface screen 208 displaying a zoomed in slide keyframe. Finally, FIG. 2 further illustrates an exemplary embodiment of a graphical user interface screen 209 displaying a zoomed in slide keyframe panned to a different position. Screens 202 through 209 incorporate the aforesaid navigation panel 210.
FIG. 3 illustrates an exemplary operating sequence of the software application executing on the wearable device 105. First, at step 301, the software application executing on the wearable device 105 connects to a known meeting. At step 302, the software application executing on the wearable device 105 registers for keyframes corresponding to each remote user's stream. At step 303, the software application executing on the wearable device 105 displays keyframes and allows the user to swipe between remote user streams as well as individual keyframes. At step 304, the software application executing on the wearable device 105 allows the user to zoom and pan keyframes on the display of the wearable device. At step 305, the software application executing on the wearable device 105 synchronizes chat content. At step 306, the software application executing on the wearable device 105 allows the user to contribute to the chat via speech-to-text or yes/no buttons. It should be noted that the above steps 302 through 306 may be executed in any suitable sequence. In one embodiment, if the wearable device is not capable of connecting with a network directly it can perform all of these functions via a middleware application running on the handheld device 111, such as a smartphone.
In one or more embodiments, the wearable device 105 may be also configured to display the live meeting stream to the user. To sale the battery, the live meeting stream may be displayed when the user turns the display of the wearable device 105 towards user's face. To this end, the wearable device 105 may be equipped with pose/orientation sensors, such as plurality of gyroscopes. In addition, the software application executing on the wearable device may be provided with note taking functionality enabling the user to dictate or otherwise input notes during the meeting.
