A teleprompter is a device that displays text on a screen in front of an actor or presenter. The text is usually scrolled automatically at a rate that is controlled by the user. Teleprompters are commonly used in television, film, and live theater.
There are several reasons why teleprompters are used. One reason is that they help the actor or presenter to remember their lines. This is especially helpful if the script is long or complex. Another reason is that teleprompters can be used to cue the actor or presenter when it is time to move to the next line or scene. This helps to keep the production running smoothly and prevents mistakes.
Teleprompters can also be used to display other information such as stage directions, props, and costume changes. This allows the actor or presenter to focus on their performance without having to worry about forgetting any important details.
Overall, teleprompters are beneficial because they help actors and presenters to remember their lines, cue them when it is time to move on, and display other important information. This makes productions run more smoothly and reduces the likelihood of mistakes being made.
