Alteration of event user interfaces of an online conferencing service

1. A method, comprising:

causing, by a server computer system via a conferencing service, display of a user interface for an event having a group of users accessing the conferencing service via a plurality of user computing devices, the displayed user interface including indications of video feeds of respective users in a particular sub-group of users in the group of users that is currently active;

storing, by the server computer system in a database, event data for the event, including content of audio and video feeds of respective users in the particular sub-group;

analyzing, by the server computer system, a set of characteristics included in the content of the audio and video feeds; and

altering, by the server computer system based on the analyzing and while the indications of the video feeds of users in the particular sub-group are being displayed, one or more aspects of the displayed user interface other than the indications of the video feeds of the particular sub-group, wherein the altering includes updating indications of video feeds of one or more users at least in the particular sub-group of users to display visual indications of speaking time of respective users in the particular sub-group of users relative to other users in the particular sub-group of users based on determined lengths of speaking time for users in the particular sub-group of users.

2. The method of claim 1 , wherein analyzing the set of characteristics included in the content of the audio and video feeds includes:

transcribing audio feeds of one or more users in the group of users;

extracting one or more keywords from the transcript of the audio feeds; and

mapping respective extracted keywords to a first set of user interface elements.

displaying, based on analyzing the audio feeds of users in the group of users, a user interface element indicating that at least two users in the group of users are speaking at the same time.

9. The method of claim 1 , wherein causing display of the user interface for the event having the group of users includes:

receiving, via the displayed user interface from a non-host user of the group of users, a sub-group request, wherein the sub-group request relates to the particular sub-group and does not require the non-host user to have administrative privileges for the conferencing service;

updating, in response to the sub-group request, the user interface, wherein the updated user interface:

permits the non-host user to perform audio and video interactions with members of the particular sub-group; and

indicates current sub-groups of other users of the group of users but does not permit the non-host user to perform audio and video interactions with users in those other sub-groups.

10. A non-transitory computer-readable medium having program instructions stored thereon that are executable by a server computer system to perform operations comprising:

causing, via a conferencing service, display of a user interface for an event having a group of users accessing the conferencing service via a plurality of user computing devices, the displayed user interface including indications of video feeds of respective users in a particular sub-group of a plurality of sub-groups of users in the group of users that is currently active;

storing, in a database, event data for the event, including content of audio and video feeds of respective users in the particular sub-group;

analyzing a set of characteristics included in the content of the audio and video feeds; and

altering, based on the analyzing and while the video feeds of users in the particular sub-group are being displayed, one or more aspects of the displayed user interface other than the indications of the video feeds of the particular sub-group, wherein the altering includes updating indications of video feeds of one or more users at least in the particular sub-group of users to display visual indications of speaking time of respective users in the particular sub-group of users relative to other users in the particular sub-group of users based on determined lengths of speaking time for users in the particular sub-group of users.

11. The non-transitory computer-readable medium of claim 10 , wherein analyzing the set of characteristics included in the content of the audio and video feeds includes:

transcribing audio feeds of one or more users in the group of users;

extracting one or more keywords from the transcript of the audio feeds; and

mapping respective extracted keywords to a first set of user interface elements.

12. The non-transitory computer-readable medium of claim 11 , wherein the altering includes causing display of the first set of user interface elements, wherein the first set of user interface elements indicates semantics of a current conversation occurring in the event.

13. The non-transitory computer-readable medium of claim 12 , wherein causing display of the first set of user interface elements includes overlaying one or more of the elements on a display of the particular sub-group of the group of users associated with the current conversation based on analysis of the audio feeds of the particular sub-group, wherein the overlayed display of the one or more user interface elements on the display of the particular sub-group is visible to users in the event outside of the particular sub-group of users.

14. The non-transitory computer-readable medium of claim 11 , wherein the mapping includes mapping respective extracted keywords to one or more symbols, and wherein the symbols indicate a current topic of a conversation occurring in the event.

15. The non-transitory computer-readable medium of claim 11 , wherein the altering includes:

displaying, based on analyzing the audio feeds of users in the group of users, a user interface element indicating that at least two users in the group of users are speaking at the same time.

16. A system, comprising:

at least one processor; and

a memory having instructions stored thereon that are executable by the at least one processor to cause the system to:

cause via a conferencing service, display of a user interface for an event having a group of users accessing the conferencing service via a plurality of user computing devices, the displayed user interface including an indication of video feeds of respective users in a particular sub-group of a plurality of sub-groups of users in the group of users that is currently active;

store, in a database, event data for the event, including content of audio and video feeds of respective users in the particular sub-group;

analyze a set of characteristics included in the content of the audio and video feeds; and

alter, based on the analyzing and while the indications of the video feeds of users in the particular sub-group are being displayed, one or more aspects of the displayed user interface other than the indications of the video feeds of the particular sub-group, wherein the altering includes updating indications of video feeds of one or more users at least in the particular sub-group of users to display visual indications of speaking time of respective users in the particular sub-group of users relative to other users in the particular sub-group of users based on determined lengths of speaking time for users in the particular sub-group of users.

17. The system of claim 16 , wherein analyzing the set of characteristics included in the content of the audio and video feeds includes:

transcribing audio feeds of one or more users in the group of users; and

inputting the transcript of the audio feeds into a machine learning model, wherein output of the machine learning model is user interface content, including one or more of the following types of content: image, video, animations, or text.

18. The system of claim 16 , wherein causing display of the user interface for the event having the group of users includes:

receiving, via the displayed user interface from a particular user of the group of users, a sub-group request, wherein the sub-group request relates to the particular sub-group and does not require the particular user to have administrative privileges for the conferencing service;
