What is an example of an interactive presentation?

An example of an interactive presentation is a keynote at a conference where the speaker pauses halfway through and asks the audience a question via Slideasy poll. Hundreds of people vote from their phones, laptops or tablets. The results show up as a word cloud on the screen. The speaker sees what the audience actually thinks. Adjusts the message based on real feedback. Then continues.

Another example is a training session where the trainer asks knowledge check questions throughout. Uses multiple choices to verify people understand the material. Sees results instantly. If people got it wrong, re-explains before moving forward.

Or a classroom where a teacher launches a word cloud asking students to brainstorm ideas about the lesson topic.
