Participant engagement detection and control system for online sessions

In a digital medium environment for a participant engagement system, a method implemented by a computing device, the method comprising:

• receiving indicators from user devices of participants during an online session, the indicators indicating user actions of the participants during the online session;
• generating a mapping of the user actions to time intervals of the online session for each user device, the mapping based on the indicators of the user actions and the mapping generated to indicate the user actions at the time intervals of the online session;
• determining a respective score for each participant in the online session at each time interval based on the mapping of the user actions, the respective score based on a weighting of the user actions for the participant at the time interval as indicated by the mapping and summing results of the weighting, the respective score indicating a level of participant engagement of the participant in the online session;
• determining at least one of the participants as a low-engagement participant based on the respective score of the low-engagement participant being below a threshold participation score;
• determining correlating participants to the low-engagement participant by correlating contents of the mapping;
• and
• determining engaging content to communicate to the low-engagement participant to increase the level of participant engagement of the low-engagement participant during the online session, the engaging content including instructor content presented by an instructor of the online session during one or more of the time intervals of the timeline when the correlating participants performed a common user action.

In a digital medium environment for a participant engagement system, a method implemented by at least one computing device, the method comprising:

• obtaining indicators from user devices of participants in an online session, the indicators indicating user actions of the participants during the online session;
• a step for generating a mapping of the user actions to a timeline of the online session, the mapping based on the indicators of the user actions and the mapping generated to indicate the user actions at time intervals of the timeline for the online session;
• a step for determining a respective score for each participant in the online session at each time interval of the timeline as indicated by the mapping by weighting the user actions at the time interval and combining results of the weighting;
• a step for determining a group of the participants of the online session having respective engagement levels that are below a threshold engagement level for at least one of the time intervals according to a ranking of the scores for the participants;
• a step for determining, from the mapping, instructor content of the online session presented by an instructor of the online session during the at least one time interval;
• and
• a step for communicating, to the instructor of the online session, an indication of the group of the participants and an additional indication of the instructor content presented by the instructor during the at least one time interval when the participants of the group have the respective engagement levels that are below the threshold engagement level.
