For example, in an embodiment, two teleconference devices 120 (in this example, “Device A” and“Device B”) connect to cloud system 110 to conduct a teleconference between Device A and Device B. Device A and Device B each record audiovisual display stream 152 using one or more associated audiovisual recording devices 128, and transmit audiovisual display stream 152 to cloud system 110. Cloud system 110 transmits Device A audiovisual display stream 152 to Device B, and transmits Device B audiovisual display stream 152 to Device A. Device A displays the Device B audiovisual display stream 152 on Device A’s display 126. Device B displays the Device A audiovisual display stream 152 on Device B’s display 126. The foregoing example is provided for illustrative purposes only, and embodiments contemplate any number of teleconference devices 120 connecting to any number of cloud systems 110 to participate in one or more teleconferences, according to particular needs.

[0034] According to embodiments, one or more cloud systems 110 may permit each teleconference device 120 to initiate and terminate teleconferences with other teleconference devices 120 within an always-on teleconference space 150. By way of example and not by way of limitation, in an embodiment, three teleconference devices 120 (in this example, “Device A,”“Device B,” and“Device C”) connect to cloud system 110. Device A and Device B initiate a teleconference between Device A and Device B in the manner described above. In this example, when the teleconference between Device A and Device B concludes, Device A subsequently initiates a teleconference with Device C, in the manner described above. One or more cloud systems 110 may permit each teleconference device 120 to initiate and terminate teleconferences with other teleconference devices 120 participating in teleconference space 150 quickly and easily.

[0035] Each teleconference device 120 may utilize one or more audiovisual recording devices 128 to record the in-room location and current perspective of one or more users associated with teleconference device 120. Each teleconference device 120 may transmit the in-room location and current perspective of one or more users to cloud system 110. Cloud system 110 may utilize the in-room location and current perspective of one or more users to modulate the perspective of the audiovisual display streams 152 transmitted to each teleconference device 120 participating in teleconference space 150, as described in greater detail below. Cloud system 110 may modulate the audiovisual display streams 152 transmitted to two or more teleconference devices 120 to approximate, for one or more users interacting with the one or more teleconference device 120 displays 126, the subjective impression of looking through a window rather than at teleconference device 120 display 126, wherein the perspective displayed on teleconference device 120 display 126 changes as the user moves about the room and changes the angle from which the user views teleconference device 120 display 126.

Administration module 302 of teleconference device 120 may access local perspective data 314, and may transmit local perspective data 314 to administration module 202 of cloud system 110, substantially in real time. [0059] FIGURE 4 illustrates exemplary method 400 of providing an always-on teleconference communication hub, according to an embodiment. Method 400 proceeds by one or more actions, which although described in a particular order may be performed in one or more other permutations, according to particular needs. In an embodiment, the actions may comprise: joining teleconference space 150 as action 402, initiating a teleconference within teleconference space 150 as action 404, monitoring user perspective as action 406, and modulating one or more teleconference space 150 audiovisual display streams 152 in response to changes in user perspective as action 408.

[0060] At action 402 of FIGURE 4, administration module 202 of cloud system 110 database 114 generates teleconference space 150 for one or more teleconference devices 120 to join. Administration modules 302 of teleconference devices 120 transmit requests to administration module 202 of cloud system 110 to join teleconference space 150. Administration module 202 of cloud system 110 accepts the requests to join teleconference space 150 from teleconference devices 120, and teleconference devices 120 join teleconference space 150. Administration module 202 records unique identifying information regarding each teleconference device 120, such as by assigning to each teleconference device 120 a unique ID and by recording the IP or MAC addresses of each teleconference device 120, in teleconference device identification data 210.

[0061] In an embodiment, for each participating teleconference device 120, audiovisual recording module 304 of teleconference device 120 activates audiovisual recording device 128 camera and microphone, and records audiovisual data 310, comprising audio data and visual data comprising a view of the room in which teleconference device 120 is situated. Audiovisual recording module 304 stores audiovisual data 310 in audiovisual data

310. Administration module 302 accesses audiovisual data 310, and transmits audiovisual data 310 as audiovisual display stream 152 to administration module 202 of cloud system 110. Administration module 202 stores inbound audiovisual display stream 152 from each teleconference device 120 in inbound audiovisual display stream data 214 of cloud system 110 database 114. Administration module 202 of cloud system 110 also stores teleconference device identification data 210 identifying the inbound audiovisual display stream 152 of each participating teleconference device 120 in inbound audiovisual display stream data 214.

[0062] At action 404, teleconference devices 120 initiate a teleconference. In an embodiment, one teleconference device 120 may transmit a request to administration module 202 of cloud system 110 to initiate a teleconference with one or more separate teleconference device 120. Administration module 202 transmits an invitation to administration module 302 of one or more separate teleconference device 120 to join a teleconference. Administration module 302 of one or more separate teleconference devices 120 transmits an acceptance of the invitation to administration module 202. Administration module 202 stores information identifying particular teleconference devices 120 participating in the teleconference in teleconference selection data 212 of cloud system 110 database 114. Teleconference display module 204 uses teleconference device identification data 210 and teleconference selection data 212 to select which portions of the inbound audiovisual display streams 152 stored in inbound audiovisual display stream data 214 will constitute the outbound audiovisual display streams 152 cloud system 110 will transmit to the teleconference devices 120 participating in the teleconference, as described in greater detail in the expanded example below. Administration module 202 transmits a specific outbound audiovisual display stream 152 to each teleconference device 120 participating in the teleconference. Administration module 302 of each teleconference device 120 stores outbound audiovisual display stream 152 in inbound audiovisual display stream data 312 of each teleconference device 120 memory 124. Graphical user interface module 306 of each teleconference device 120 accesses inbound audiovisual display stream data 312, and displays the data 310 contained therein on teleconference device 120 display 126, illustrated by FIGURE 6.

[0063] At action 406, each teleconference device 120 monitors the in-room location and current perspective of one or more associated users. Teleconference device 120 perspective tracking module 308 uses audiovisual recording device 128 camera to record a view of the room in which teleconference device 120 is operating. Perspective tracking module 308 of teleconference device 120 uses the room visual information to estimate the size of the room and the position and orientation of teleconference device 120 within the room. Perspective tracking module 308 next identifies the face of one or more users associated with teleconference device 120. Perspective tracking module 308 compares the size of one or more user faces with the estimated size of the room to estimate the distance from teleconference device 120 to one or more users. Perspective tracking module 308 also analyzes the off-center angle measured from the camera of teleconference device 120 to one or more user faces to estimate the location of one or more users in relation to teleconference device 120. Administration module 302 transmits local perspective data 314 of one or more teleconference device 120 users to administration module 202 of cloud system 110. Administration module 202 stores local perspective data 314 of one or more teleconference device 120 users in teleconference device perspective data 218 of cloud system 110 database 114.

[0064] At action 408, cloud system 110 modulates one or more teleconference space 150 audiovisual display streams 152 in response to changes in user perspective. Perspective calculation module 206 of cloud system 110 selects different portions of one or more inbound audiovisual display streams 152 to comprise one or more outbound audiovisual display streams 152, according to particular needs and as described in greater detail in the expanded example below. Teleconference system 100 terminates method 400 when all teleconference devices 120 exit teleconference space 150.

[0065] In order to illustrate the operation of providing an always-on teleconference communication hub, an expanded example is now provided. In the following example, exemplary teleconference system 502 comprises cloud system 110, two teleconference devices 120 (henceforth, “Device 504” and “Device 506”), network 130, and three communication links 140-142b. Although a particular number of cloud systems 110, teleconference devices 120, networks 130, and communication links 140-142b are shown and described, embodiments contemplate any number of cloud systems 110, teleconference devices 120, networks 130, or communication links 140-144, according to particular needs.

[0066] FIGURE 5 illustrates exemplary teleconference system 502 executing method 400 of FIGURE 4, according to an embodiment. Continuing the example, each of the two teleconference devices 120, Device 504 and Device 506, comprises processor 122, memory 124, display 126, and a single audiovisual recording device 128. In this example, display 126 comprises a 55-inch 16:9 LCD with a pixel resolution of 3,840 x 2,160 pixels (4K resolution). Audiovisual recording device 128 comprises a single camera and microphone, mounted to the top center of Device 504 and Device 506 display 126. In this example, the camera is configured with a 180-degree field-of view lens, which allows the camera to view the rooms in which Device 504 and Device 506 are respectively situated. Additionally, in this example, a single user (henceforth, user 602) is associated with Device 504, and two users (henceforth, users 604) are associated with Device 506, illustrated by FIGURE 6. Although teleconference devices 120 of this example are described comprising a particular display 126 and audiovisual recording device 128 configuration, and being associated with a particular number of users 602-604, embodiments contemplate teleconference devices 120 comprising any number and configuration of displays 126 and audiovisual recording devices 128, and being associated with any number of users, according to particular needs.

[0067] Continuing the example, at action 402 of FIGURE 4, administration module 202 of cloud system 110 database 114 generates teleconference space 150. Administration modules 302 of Device 504 and Device 506 transmit requests to administration module 202 of cloud system 110 to join teleconference space 150. Administration module 202 of cloud system 110 accepts the requests to join teleconference space 150 from Device 504 and Device 506, and Device 504 and Device 506 join teleconference space 150. Administration module 202 records unique identifying information regarding Device 504 and Device 506, such as by assigning to Device 504 and Device 506 unique IDs and by recording the IP or MAC addresses of Device 504 and Device 506, in teleconference device identification data 210.

[0068] Continuing the example, audiovisual recording module 304 of Device 504 activates Device 504 audiovisual recording device 128 camera and microphone, and records audiovisual data 310, comprising audio data and visual data comprising a 180-degree field of view of the room in which Device 504 is situated. Audiovisual recording module 304 of Device 504 stores audiovisual data 310 in audiovisual data 310 of Device 504 memory 124. Administration module 302 of Device 504 accesses audiovisual data 310 stored in Device 504 memory 124, and transmits audiovisual data 310 as audiovisual display stream 152 to administration module 202 of cloud system 110. Administration module 202 stores the inbound audiovisual display stream 152 of Device 504, comprising a 180-degree field of view of the room in which Device 504 is situated, in inbound audiovisual display stream data 214 of cloud system 110 database 114. Administration module 202 of cloud system 110 also stores teleconference device identification data 210 associating the inbound audiovisual display stream 152 of Device 504 with Device 504 in inbound audiovisual display stream data 214.

[0069] Device 506 executes the actions described above with respect to Device 504 to transmit Device 506 audiovisual display stream 152, comprising audio data and visual data comprising a 180-degree field of view of the room in which Device 506 is situated, to administration module 202 of cloud system 110. Administration module 202 stores the inbound audiovisual display stream 152 of Device 506, comprising a 180-degree field of view of the room in which Device 506 is situated, in inbound audiovisual display stream data 214 of cloud system 110 database 114. Administration module 202 also stores teleconference device identification data 210 associating the inbound audiovisual display stream 152 of Device 506 with Device 506 in inbound audiovisual display stream data 214.

[0070] Continuing the example, at action 404, Device 504 and Device 506 initiate a teleconference between Device 504 and Device 506. In this example, Device 504 transmits a request to administration module 202 of cloud system 110 to initiate a teleconference with Device 506. Administration module 202 transmits an invitation to administration module 302 of Device 506 to join a teleconference with Device 504. Administration module 302 of Device 506 transmits an acceptance of the invitation to administration module 202. Administration module 202 stores information identifying the in-process Device 504-Device 506 teleconference in teleconference selection data 212 of cloud system 110 database 114.

[0071] Continuing the example, teleconference display module 204 of cloud system 110 database 114 accesses the identification data stored in teleconference device identification data 210, as well as the information identifying Device 504-Device 506 teleconference stored in teleconference selection data 212. Teleconference display module 204 uses teleconference device identification data 210 and teleconference selection data 212 to select which portions of the inbound audiovisual display streams 152 of Device 504 and Device 506, stored in inbound audiovisual display stream data 214, will constitute the outbound audiovisual display streams 152 of Device 504-Device 506 teleconference. In other embodiments in which teleconference system 100 supports separate teleconferences between a plurality of teleconference device 120 pairs simultaneously, teleconference display module 204 may utilize teleconference selection data 212 to select which outbound audiovisual display stream 152 administration module 202 of cloud system 110 will transmit to each teleconference device 120, according to particular needs.

[0072] Continuing the example, teleconference display module 204 accesses teleconference device identification data 210 and teleconference selection data 212, and determines there is currently a single teleconference in progress, between Device 504 and Device 506. Teleconference display module 204 accesses teleconference device perspective data 218 and Device 504 audiovisual display stream 152 and Device 506 audiovisual display stream 152, stored in inbound audiovisual display stream data 214 of cloud system 110 database 114. Teleconference display module 204 generates two outbound audiovisual display streams 152. Device 504 outbound audiovisual display stream 152, which administration module 202 of cloud system 110 will transmit to Device 504, comprises in this example selection portions of audiovisual display stream 152 that Device 506 previously transmitted to cloud system 110. More specifically, teleconference display module 204 accesses Device 506 inbound audiovisual display stream 152 and selects the audio data stored therein, and a narrowed, central field of view portion of the original 180-degree view of the room in which Device 506 is situated, to comprise Device 504 outbound audiovisual display stream 152. Similarly, teleconference display module 204 accesses Device 504 inbound audiovisual display stream 152 and selects the audio data stored therein, and a narrowed, central field of view portion of the original 180-degree view of the room in which Device 504 is situated, to comprise Device 506 outbound audiovisual display stream 152. By initially choosing the narrowed, central field of view portions of the original Device 504 and Device 506 inbound audiovisual display streams 152, illustrated in FIGURE 6, teleconference display module 204 and perspective calculation module 206 will subsequently be able to “pan” the outbound audiovisual display streams 152 to other portions of the original 180- degree inbound audiovisual display streams 152 in response to user movement and/or changes in user perspective to simulate the subjective experience of looking through a window, as illustrated in FIGURES 7 and 8.

[0073] Teleconference display module 204 stores Device 504 outbound audiovisual display stream 152 and Device 506 outbound audiovisual display stream 152 in outbound audiovisual display stream data 216 of database 114. Administration module 202 of cloud system 110 accesses outbound audiovisual display stream data 216, and transmits Device 504 outbound audiovisual display stream 152 to administration module 302 of Device 504. Similarly, administration module 202 transmits Device 506 outbound audiovisual display stream 152 to administration module 302 of Device 506.

[0074] Administration module 302 of Device 504 stores Device 504 outbound audiovisual display stream 152, transmitted from cloud system 110 to Device 504, in inbound audiovisual display stream data 312 of Device 504 memory 124. Graphical user interface module 306 of Device 504 accesses inbound audiovisual display stream data 312, and displays the data contained therein on Device 504 display 126, as illustrated by FIGURE 6. Simultaneously, administration module 302 of Device 506 stores Device 506 outbound audiovisual display stream 152, transmitted from cloud system 110 to Device 506, in inbound audiovisual display stream data 312 of Device 506 memory 124. Graphical user interface module 306 of Device 506 accesses inbound audiovisual display stream data 312, and displays the data contained therein on Device 506 display 126.

[0075] FIGURE 6 illustrates Device 504 participating in a teleconference with Device 506, according to an embodiment. Continuing the example, Device 504 displays on Device 504 LCD display 126 the audiovisual information contained in Device 504 outbound audiovisual display stream 152 that administration module 202 of cloud system 110 transmitted to Device 504. In this example, Device 504 displays on Device 504 LCD display 126 the narrowed, central field of view portion of the original 180-degree view of the room in which Device 506 is situated, previously selected by teleconference display module 204 of cloud system 110. Device 504 displays Device 506 users 604, and allows Device A user 602 to see, hear, and communicate with Device 506 users 604. Although not illustrated in FIGURE 6, Device 506 simultaneously displays on Device 506 LCD display 126 audiovisual information recorded by the camera and microphone of Device 504. Although a specific teleconference configuration is shown and described, embodiments contemplate outbound teleconference configurations displaying any configuration of visual and/or audio data, according to particular needs.

[0076] Continuing the example, at action 406, Device 504 monitors the in-room location and current perspective of Device 504 user 602. Perspective tracking module 308 of Device 504 uses the camera of Device 504 to record a 180-degree view of the room in which Device 504 is operating. Perspective tracking module 308 of Device 504 uses the room visual information to estimate the size of the room and the position and orientation of Device 504 in the room. Perspective tracking module 308 of Device 504 next identifies the face of Device 504 user 602. Perspective tracking module 308 compares the size of user 602 face with the estimated size of the room to estimate the distance from Device 504 to user 602. Perspective tracking module 308 of Device 504 also analyzes the off-center angle measured from the camera of Device 504 to user 602 face to estimate the location of user 602 in the room relative to Device 504. In this example, perspective tracking module 308 of Device 504 continuously records the in-room location and current perspective of Device 504 user 602 substantially in real time, and records the in-room location and current perspective of Device 504 user 602 in local perspective data 314 of teleconference device 120 memory 124. Similarly, Device 506 executes the actions described above to record and store the in-room location and current perspective of Device 506 users 604 substantially in real time.

[0077] Continuing the example, administration module 302 of Device 504 transmits local perspective data 314 of Device 504 user 602 to administration module 202 of cloud system 110. Administration module 202 stores local perspective data 314 of Device 504 user 602 in teleconference device perspective data 218 of cloud system 110 database 114. In this example, administration module 302 of Device 504 continuously transmits updated local perspective data 314 of Device 504 user 602 to cloud system 110 substantially in real time. Similarly, Device 506 executes the actions described above to continuously transmit updated local perspective data 314 of Device 506 users 604 substantially in real time.

[0078] Continuing the example, at action 408, perspective calculation module 206 of cloud system 110 selects different portions of Device 506 inbound audiovisual display stream 152 to comprise Device 504 outbound audiovisual display stream 152, depending on the current position of Device 504 user 602 with respect to Device 504. For example, and as illustrated in FIGURE 7, by deviating from the initial narrowed, central field of view of the original 180-degree field of view of the room in which Device 506 is situated, and by panning to the left of the initial narrowed, central field of view as Device 504 user 602 moves to the right side of Device 504 (as interpreted from the perspective of user 602 facing Device 504), perspective calculation module 206 enables outbound audiovisual display stream 152 transmitted to Device 504 to approximate the perspective change that a window directly into Device 506 room would present to Device 504 user 602. Similarly, and as illustrated in FIGURE 8, by panning to the right of the initial narrowed, central field of view as Device 504 user 602 moves to the left of Device 504 (as interpreted from the perspective of user 602 facing Device 504), perspective calculation module 206 again approximates the perspective change that a window directly into Device 506 room would present to Device 504 user 602.

[0079] Continuing the example, as the teleconference between Device 504 and Device 506 progresses, Device 504 user 602 moves from a straight-ahead viewing location with respect to Device 504 to the right of Device 504 (as interpreted from the perspective of user 602 facing Device 504). Perspective tracking module 308 of Device 504 records the change in the perspective of Device 504 user 602 in local perspective data 314 of Device 504. Administration module 302 of Device 504 transmits Device 504 local perspective data 314 to administration module 202 of cloud system 110. Administration module 202 stores Device 504 local perspective data 314 in teleconference device perspective data 218 of cloud system 110 database 114.

[0080] Continuing the example, perspective calculation module 206 of cloud system 110 administrator 112 accesses Device 504 local perspective data 314 stored in teleconference device perspective data 218. Perspective calculation module 206 determines that Device 504 user 602 has changed perspective with respect to Device 504. Perspective calculation module 206 transmits the information that Device 504 user 602 has changed perspective to teleconference display module 204. Teleconference display module 204 responds by accessing Device 506 inbound audiovisual display stream 152 stored in inbound audiovisual display stream data 214, and by selecting a leftward-looking portion of the original 180-degree view of the room in which Device 506 is situated, as compared to the narrowed, central field of view teleconference display module 204 had previously selected to comprise outbound audiovisual display stream 152. Teleconference display module 204 stores the leftward-looking portion of Device 506 inbound audiovisual display stream 152 as the updated Device 504 outbound audiovisual display stream 152 in outbound audiovisual display stream data 216. Administration module 202 of cloud system 110 transmits the updated Device 504 outbound audiovisual display stream 152 to administration module 302 of Device 504. Device 504 displays the updated Device 504 outbound audiovisual display stream 152 on Device 504 LCD display 126, as illustrated in FIGURE 7.

[0081] FIGURE 7 illustrates a second configuration of Device 504 participating in a teleconference with Device 506, according to an embodiment. Continuing the example, Device 504 displays on Device 504 LCD display 126 the audiovisual information contained in Device 504 outbound audiovisual display stream 152 that administration module 202 of cloud system 110 transmitted to Device 504. In this example, Device 504 displays on Device 504 LCD display 126 the narrowed, left-angled field of view portion of the original 180- degree view of the room in which Device 506 is situated, previously selected by teleconference display module 204 and perspective calculation module 206 of cloud system 110. Although not illustrated in FIGURE 7, Device 506 simultaneously displays on Device 506 LCD display 126 audiovisual information recorded by the camera and microphone of Device 504. Although a specific teleconference configuration is shown and described, embodiments contemplate outbound teleconference configurations displaying any configuration of visual and/or audio data, according to particular needs. [0082] Continuing the example, teleconference system 100 continually updates the outbound audiovisual display streams 152 in response to changes in the viewing perspectives of Device 504 user 602 and Device 605 users 604. For example, when Device 504 user 602 moves to the left side of Device 504 (as interpreted from the perspective of user 602 facing Device 504), teleconference system 100 performs actions 406 and 408 described above to update Device 504 outbound audiovisual display stream 152 as illustrated in FIGURE 8.

[0083] FIGURE 8 illustrates a third configuration of Device 504 participating in a teleconference with Device 506, according to an embodiment. Continuing the example, Device 504 displays on Device 504 LCD display 126 the audiovisual information contained in Device 504 outbound audiovisual display stream 152 that administration module 202 of cloud system 110 transmitted to Device 504. In this example, Device 504 displays on Device 504 LCD display 126 the narrowed, right-angled field of view portion of the original 180- degree view of the room in which Device 506 is situated, previously selected by teleconference display module 204 and perspective calculation module 206 of cloud system 110. Although not illustrated in FIGURE 8, Device 506 simultaneously displays on Device 506 LCD display 126 audiovisual information recorded by the camera and microphone of Device 504. Although a specific teleconference configuration is shown and described, embodiments contemplate outbound teleconference configurations displaying any configuration of visual and/or audio data, according to particular needs. Concluding the example, teleconference system 100 terminates method 400 when Device 504 and Device 506 exit teleconference space 150.
