Interaction
Mentimeter allows you to launch polls at the start/during/after your presentation, to get opinions and feedback. Your audience need their mobile phones or tablets.
Slido is an alternative. You might need an alternative as all of these tools have limits on the number of free options.
Kahoot is a more game-like option, aimed mainly at younger people, but an interactive quiz might help to spice up your talk.
Quizizz is an alternative to Kahoot, very nice looking on screen.
