An autocue, or a teleprompter as they are called in the USA, is what presenters use so as not to have to learn lines. It sits in front of a camera lens and uses a reflected image of reversed text to project the script right in front of the camera so it looks like you're looking directly at the audience. It is either operated by the presenter, using a wireless remote control, or by an autocue operator. It's fairly easy to get to grips with and usually people are up and running after just one read through. It's an awful lot better than watching a video where the speaker is looking at a script to the side or below the camera! Next time you watch the news, watch the newsreaders eyes. You can tell they're reading, even though they seem to be looking straight at you.
