A teleprompter, also known as a display device that prompts the person speaking with an electronic visual text of a speech or script. Teleprompters have traditionally been used in two main scenarios – by television presenters who want to be able to look straight in to the camera whilst reading the script, or by presidents, politicians and public speakers who want to be able to maintain natural eye contact with their audience rather than looking down at their notes. In more recent times, the use of teleprompters has widened to include any scripted video production, video bloggers, PowerPoint presentations, as well as singers performing on stage as a way to help remember their lines.
