Interesting links I found recently:
One of my biggest pet peeves is people reading from a Powerpoint slideshow when giving a presentation.
The powerpoint slide show is to guide your audience about what YOU are presenting, speaking about. It should NOT convey all the information nor should it be YOUR (The speakers) guide or prompter.
Ideally, the speaker should “know” the topic and speak from his/her mind and allow the bullet points/diagrams to connect what you are talking about.
It is quite irritating that the speaker turns away from the audience to look at the screen to gather his/her thoughts or determine what to talk about next. For the love of the audience, stop referring to the screen and look at the audience when you are talking to them.
