  • participants at different conference sites can use different types of endpoints (e.g. notebook computers, handheld devices, conference studio equipment, etc.).
  • the remote locations of meeting participants and possible use of different equipment at different conference sites can make it difficult to identify roles of participants, at least partly due to the remote participants being presented as images in a layout that may not convey or may mis- convey roles of participants.
  • the concept of meeting spaces in an overall meeting area where participants can gather typically does not exist.
  • techniques or mechanisms are provided to provide for improved communications (verbal and non-verbal) in meetings established over a network.
  • Such techniques or mechanisms can perform grouping of meeting participants (and possibly resources), and define a meeting layout according to the groupings.
  • the grouping of meeting participants is performed to emulate the groups of a physical meeting, such as those depicted in Fig. 1 .
  • Fig. 1 depicts the meeting participants being located in a single location, the grouping according to some implementations for a meeting established over a network can define a group including participants from multiple conference sites.
  • the grouping of meeting participants can be according to the roles of the participants. As discussed above, when meeting participants carry out tasks in meetings, they take on roles specific to those tasks. For example, presenters and meeting facilitators have specific roles in meetings that are different from a role of an audience member. A role can imply a specific task (e.g. a presenter role implies a presentation task). A role can sometimes imply multiple tasks (e.g. a role such as a meeting facilitator can imply a task of organizing the meeting and a task as an audience member). When multiple participants have the same role (e.g. there are two presenters or there are multiple audience members), such participants can be included within a respective group. The grouping of participants by roles can produce various groups, such as those shown in Fig. 1 (e.g. 1 10, 1 12, 1 14, 1 1 6, 1 8).

  • space-based groups are also defined, then a participant can be part of a role-based group and the space-based group.
  • memberships of the different groups can be disjoint at a particular point in time— in other words, there is no overlap of members of the different groups (no participant is a member of more than one group) at this particular point in time.
  • a meeting layout can include a display layout, which defines display regions for presenting respective media streams of multiple groups, to allow for more effective communications (both verbal and non-verbal) among the participants.
  • a "media stream" can refer to content for depicting respective participant(s) or resource(s), where the media stream can contain audio/video data, an image, and so forth.
  • the meeting layout can also define an audio layout, which specifies whether audio from participants in a first group would be audible to participants in a second group. For example, audio from participants in an audience group can be audible among the participants in the audience group, but may not be audible to a presentation group. On the other hand, audio from the presentation group can be audible to participants of the audience group.
  • the audio layout can also specify whether audio from a particular group is to be mono or stereo.
  • meeting participants can more easily recognize roles of other participants, and participants can more effectively perform communications with each other and carry out their respective tasks. Due to differences in endpoints (e.g. different video and/or audio capabilities) located at different conference sites for the meeting established over a network, different participants may have different perceptions of the "virtual meeting room," which represents the overall meeting area in the physical meeting depicted in Fig. 1 .
  • the meeting layout that can be defined according to some implementations allows for a shared conceptual representation of the virtual meeting room and of the various groups of participants to be presented, such that more effective communications (verbal and non-verbal) can be achieved.

  • An example property associated with a meeting space is spatial order, which can refer to an ordering of participants, such as around a table, in a particular meeting space, and so forth. Spatial ordering can preserve non-verbal
  • audio/video visibility indicates whether a first space generates audio/video that is audible/visible to a second space.
  • audio/video data generated at the podium 104 is audible and visible to participants in the audience seating area 108.
  • a further property of a meeting space includes scale preservation, which indicates whether or not scale is preserved across positions within a space. If scale is to be preserved, then the images of the participants in the meeting space are maintained to scale (in other words, they are maintained to have the same size). In other examples, especially for a space such as the audience seating area 108 that can include a relatively large number of participants, images of different ones of the participants may be presented with a larger size than other ones of the particpants.
  • Another property of a space includes a tool property, which indicates what collaboration tool is available to participants within the space.
  • the collaboration tool can include, as an example, a video projector, a whiteboard, and so forth.
  • Another property of a space includes a priority property, which indicates whether the space is given display priority over other spaces.
  • the podium space 104 can be given greater priority in a display space to be displayed in a display device than the audience seating area 108.
  • the greater priority associated with the podium space 104 may mean that the media stream associated with the podium space 104 is larger in size than the media stream for participants in the audience seating area 108.

  • Layout rules further include rules that are applicable to a particular endpoint— such layout rules are referred to as local layout rules.
  • Local layout rules applicable to a particular endpoint can depend upon the type of the particular endpoint.
  • a handheld device such as a personal digital assistant or smartphone
  • tablet computer can have a display device with a relatively small display area.
  • conference studio equipment can include a display device having a relatively large display area.
  • the meeting layout can allocate a larger portion of the display area for an active collaborator (e.g., presenter) versus the portion of the display area allocated to non-active participants, as compared to a display device that has a relatively large display area.
  • Local layout rules can also be based on preferences of user(s) of a particular endpoint. Different users can thus set different local layout rules applicable to respective endpoints.
  • a general layout rule can specify that the media stream for an active participant (e.g., presenter) be positioned in the proximity of the media stream for an associated resource (e.g. , a Powerpoint presentation).
  • "Proximity" can be defined in different ways— in some examples, the media stream for an active participant and the media stream for the resource are in "proximity” if the media streams are adjacent to each other, or within some specified distance of each other. As yet further examples, the media streams for the active participant and the resource are in "proximity” if there is some indication of association between the media streams (e.g., a graphic linking the media streams).
  • Another example general layout rule can specify that non-active participants, such as participants in an audience group (e.g., 1 16 in Fig. 1 ) be placed in proximity with each other to visually associate such non-active participants. Also, another general layout rule can specify that members of a particular conference site be placed in closer proximity to each other in the meeting layout relative to members at other conference sites.
  • the layout rules according to some implementations seek to achieve a balance between providing flexibility to users at endpoints, and providing for more consistent presentation of media streams of meetings.
