 Contents
A teleprompter is a display device that prompts the person speaking with an electronic visual text of a speech or script. Using a teleprompter is similar to the practice of using cue cards . The screen is in front of the lens of the camera, and the words on the screen are reflected to the eyes of the speaker using a two-way mirror. As the speaker does not need to look down to consult written notes, he or she appears to have memorized the speech or be speaking spontaneously.
