How do see-through autocues work?
An autocue, or teleprompter, is the modern equivalent of cue cards. See-through autocues are designed to make the speaker seem like they are addressing the audience directly rather than reading a running script. Freestanding see-through autocues for public speeches are used in pairs so that the speaker can look around the audience and always be able to read one. Teleprompters were first invented in the 1950s to help television presenters who had to memorise long scripts. In the 1980s the script started to be electronically run on a PC rather than a mechanised paper scroll.
