Audience, participant, or event engagement is the dialogue, at an event, between the event participants, presenters, sponsors and content. While audience engagement at in-person events has traditionally been facilitated through the raising of hands and passing of microphones, technology is now available for all types of events (in-person, online, hybrid, and on-demand) with mobile and web-based apps that support polls, discussion threads, chats, online Q&A, badge games, leaderboards, and more with audiences that are attending events in-person or virtually.
