DESCRIPTION OF EXAMPLE EMBODIMENTS
Overview
A method implemented on a first computing device includes: receiving video conference data for a video conference session; receiving battery level information for at least one other computing device participating in the video conference session, where the at least one other computing device is a mobile computing device; presenting the video conference session on the first computing device, where the presenting comprises presenting a representation of the battery level information associated with at least one the mobile computing device.
Detailed Description of Example Embodiments
The services provided by mobile computing devices are generally limited by the capacity of their batteries. Accordingly, a common concern of mobile computing is that a device's battery may run out at an inopportune time, for example, while the user of the device is participating in a video conference session. If the battery runs out during a video conference session, the associated mobile user suddenly “disappears” from the session, inconveniencing both the affected user as well as the other participants.
Reference is now made to FIG. 1 which illustrates an exemplary video conference session display 5 as it may be displayed on the display screen of a participant of a video conference session. Display 5 may be presented by any suitably configured computing device, such as, for example, a personal computer, a mobile computing device, a video conference room or an individual video conference unit. Display 5 as depicted represents the presentation of an exemplary video session conference, comprising shared desktop view 10, participant names 20 and participant video feed 25.
It will be appreciated that as depicted in FIG. 1, display 5 may comprise other common video conference features as well, such as a variety of status indicators associated with participant names 20, for example: thumbnail images of the participants, video feed indicators, audio mute/open/active indicators, and the like. In accordance with embodiments of the present invention, display 5 may also comprise battery level indicators 21. As shown in FIG. 1, each battery level indicator 21 may be associated with a participant name 20. For example, battery level indicator 21B is associated with participant name 20B (Benoit LaPOINTE); battery level 21D is associated with participant name 20D (Paul Schmitt); and battery level indicator 21E is associated with participant name 20E (Rob Wang). It will be appreciated that battery level indicators 21 may generally be associated specifically with participant names 20 that are using mobile devices to participate in the current video conference session.
The icons used for battery level indicators 21 may indicate a current battery level for the mobile computing device used by each associated participant. For example, the percentage of the area of the icon for a battery level indicator 20 that is “filled in”, i.e., black, in FIG. 1, may approximate the percentage of the charge remaining in the associated battery. Accordingly, as per the exemplary embodiment of FIG. 1, battery level indicator 21B appears to be about 80% full, thereby indicating that the associated battery, i.e., the battery on the mobile computing device used by Benoit LaPOINTE, is about 80% full. Similarly, the con for battery level indicator 21D appears to be about 15% full, thereby indicating that the battery for Paul Schmitt's mobile computing device is approximately 15% full. The icon battery level indicator 21E shows a thunderbolt symbol, thereby indicating that the associated mobile computing device, i.e. that of Rob Wang is currently charging and therefore, presumably, regardless of its battery level, Rob Wang's mobile computing device is not currently in danger of suddenly dropping out of the video conference session without warning.
It will be appreciated that, as depicted, battery level indicators 21 may only provide approximate information regarding battery levels of the associated mobile computing devices. For example, the icon of battery level indicator 21D may actually represent a 18%, charge in the associated battery, yet the difference between 15% and 18% full may not be discernable when viewing battery level indicator 21D. Accordingly, display 5 may be configured to provide a numeric representation of the percentage upon user request. For example, the user may “mouse over” battery level indicator 21D at which point a numeric representation, i.e. “18%” may be displayed over or near the display of battery level indicator 21D. It will be appreciated by one of ordinary skill in the art that other well-known user interface (UI) methods may be employed to request the numeric display. Alternatively, display 5 may be configured to display battery level indicators 21 using numeric representation by default.
Display 5 may be configured to provide a warning in the event that the battery level of a participant's battery is determined to be below a configurable battery warning threshold. For example, as depicted in the exemplary embodiment of FIG. 1, display 5 may also comprise battery level warning 30. As depicted in FIG. 1, battery level warning 30 may indicate that Paul Schmitt's battery is now at 22%, which may be less than the configurable battery warning threshold. For example, the battery warning threshold may have been configured as 22%. Alternatively, the battery warning threshold may have been configured with a higher percentage, such as, for example, 25%.
Battery level warning 30 may be displayed in response to one or more of the battery levels as represented by battery level indicators being equal of below the battery warning threshold. It will be appreciated by one of ordinary skill in the art that the window for battery level warning level 30 may be closed by the user using known UI methods, for example, by clicking the “X” in the top right corner of battery level warning 30, inputting an F4 key combination and/or any other suitable method. It will similarly be appreciated that battery level warning 30 may be displayed repeatedly according to battery level. For example, battery level warning 30 may be displayed as soon as the battery level threshold is reached, and thereafter again each time the associated battery goes down another configurable percentage, for example, every 5%. Battery level warning 30 may also be configured with distinctive colors and/or to flash on and off in order to attract the user's attention. Alternatively, or in addition, battery level warning 30 may also be configured as an audio alert.
Reference is now made to FIG. 2, which is a block diagram drawing of an exemplary video conference server 200, constructed and operative in accordance with embodiments of the disclosure, and arrayed in communication with mobile computing devices 100 and computing device 101. Video conference server 200 comprises at least one processor 210; I/O module 120; and video conference application 130. It will be appreciated that video conference server 200 comprises hardware and software components, such as are well-known in the art. It will similarly be appreciated that video conference server 200 may comprise other components that are not depicted in FIG. 1.
Video conference application 230 may be a server-side implementation of any suitable video conference application such as, for example, Cisco WebEx or GoToMeeting from Citrix Systems, Inc. Video conference application 230 comprises battery monitoring module 235 which, as will be discussed hereinbelow, is configured to provide battery monitoring information to one or more of the participants of a video conference session.
Video conference server 200 is configured to facilitate an exemplary video conference session between users of mobile computing devices 100 and computing device 101. Mobile computing devices 100 may be any mobile computing device operative to participate in a video conference session. For example, as depicted in FIG. 2, mobile computing devices 100A and 100E may be laptop computers; mobile computing devices 100B and 100C may be smartphones; and mobile computing device 100D may be a computer tablet. Computing device 101 may be any non-mobile computing device operative to participate in a video conference session. For example, computing device 101 may be a desktop personal computer or a dedicated video conference device or facility. It will be appreciated that the inclusion of computing device 101 in FIG. 2 may be exemplary; embodiments of the present disclosure do not necessarily require a non-mobile video conference participant. It will further be appreciated that mobile computing devices 100 are a kind of computing device, as such similar to computing devices 101. In the context of the present disclosure, mobile computing devise 100 may therefore be differentiated for other types of computing devices 100 by the ability to operate using an internal battery, as opposed to dependence on an external power source for operation.
Reference is now made to FIG. 3 which illustrates a block diagram of an exemplary mobile computing device 100. It will be appreciated by one of skill in the art that each of computing devices 100 comprises hardware and software components that may provide video conferencing functionality. For example, each mobile computing device 100 may comprise at least processor 110, I/O module 120, display screen 140 and video conference client application 150. It will be appreciated that mobile computing device 100 may also comprise at least a microphone and/or a speaker (not shown) in order to facilitate user participation in a video conference session.
It will be appreciated that mobile computing device 100 may comprise more than one processor 110. For example, one such processor 110 may be a special purpose processor operative to execute video conference client application 150. It will be appreciated that video conference client application 150 may be an application implemented in software and/or hardware on mobile computing device 100. Video conference client application 150 may be any suitable application video conferencing application such as, for example, Cisco WebEx or GoToMeeting from Citrix Systems, Inc. It will be appreciated by one of skill in the art that computing device 101 may comprise similar components to at least facilitate participation in a video conference session.
Mobile computing device 100 also comprises battery 130 to facilitate mobile usage. Video conference client application 150 may comprise battery monitoring module 155 to monitor usage of battery 130. It will be appreciated that battery monitoring module 155 may alternatively be configured as an external module called by video conference client application 150. Battery monitoring module 155 may be implemented in software and/or hardware and may configured in accordance with the operating environment of mobile computing device 100. For example, if mobile computing device 100 is an Android device, battery monitoring module 155 may be configured to use Android's BatteryManager class to determine remaining battery capacity for battery 130 and whether or not it is currently charging. It will be appreciated by one of skill in the art that similar functionality may be provided in other operating environments.
Reference is now also made to FIG. 4 which illustrates a battery monitoring process 300 to be executed by video conference client application 150 in the context of the presentation of display 5 (FIG. 1) for an associated video conference session. It will be appreciated that display 5 may be presented on any device participating in a video conference session, regardless of whether or not the device presenting display 5 comprises battery 130 (FIG. 2) or not. Accordingly, battery monitoring process 300 may be executed on either mobile computing devices 100 and/or computing devices 101. If process 300 is executed on mobile computing device 100, battery monitoring module 155 may be invoked to check (step 310) the battery state for mobile computing device 100. The battery state may include information such as, for example, remaining battery capacity for battery 130 and whether or not it is currently charging. Video conference client application 150 may forward (step 320) the battery state information to video conference server 200. It will, however, be appreciated by one of skill in the art that a given mobile computing device 101 may be configurable to allow/disallow the performance of steps 310 and 320.
It will similarly be appreciated by one of skill in the art that access to the functionality provided by process 300 may be limited. For example, in accordance with embodiments of the present disclosure, process 300 may be limited to use by the host of a current video conference session, and/or to other participants granted access by the host or otherwise.
Process 300 continues on both mobile computing device 100 and computing device 101 with video conference client application 150 receiving (step 330) audio and/or visual data from video conference server 200 via I/O module 120. Video conference client application 150 also receives (step 340) battery level information from video conference server 150. It will be appreciated by one of skill in the art, that the battery level information may be collated by battery monitoring module 235 (FIG. 2) from mobile computing devices 100 as a result of step 320 as disclosed hereinabove.
Video conference client application may format (step 350) a visual representation of the battery level based on the received battery level information. The visual representation may be, for example, in the form of battery level indicators 21 as depicted in FIG. 1. Video conference client application may present (step 360) the video conference including battery level indicators 21 as depicted in FIG. 1.
If the battery level associated with one of the participants is lower than the battery warning threshold (step 370), video conference client application 150 may “popup” (step 375) a low battery warning such as battery level warning 30 in FIG. 1. If a battery information requested is detected (step 380), video conference client application may display (step 385) the requested battery information. Step 380 may comprise, for example, detecting a mouse-over or menu driven request. Step 385 may comprise displaying an integer-based representation of battery level indicator 21.
Processing control may then return to the beginning of process 300; i.e., step 310 when processing on mobile computing device 100, and step 330 when processing on computing device 100. It will be appreciated that the performance of steps 310 and 320 may be configurable; in order to conserve resources, process 300 may be configured every “N” times that control returns to the start of process 300.
It is appreciated that software components of the present invention may, if desired, be implemented in ROM (read only memory) form. The software components may, generally, be implemented in hardware, if desired, using conventional techniques. It is further appreciated that the software components may be instantiated, for example: as a computer program product or on a tangible medium. In some cases, it may be possible to instantiate the software components as a signal interpretable by an appropriate computer, although such an instantiation may be excluded in certain embodiments of the present invention.
It is appreciated that various features of the invention which are, for clarity, described in the contexts of separate embodiments may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment may also be provided separately or in any suitable subcombination.
