One is left wondered, seeing the news anchor and television reporters delivering information seamlessly on the camera. Thanks to the modern and digital presidential teleprompter system. A presidential teleprompter system, also called ‘autocue’ or ‘Tele script’, helps the presenter to read a pre-prepared script or dialogue in the real time without any necessity to memorize the script. Generally, the teleprompter systems are available in two versions, a studio teleprompter, and a presidential teleprompter.
A studio teleprompter consists of one or more screens and a reflecting glass called beam splitting mirrors pivoted and adjusted to a fixed angle of view for the reader to see the running script on the screen. The other functions to control the scrolling script is also included in the software. The reflection glass is a specialized glass which enables most of the light from the front of the glass to pass through it and an appropriate amount of it to be reflected for the reader to see the script on the glass. The transparency helps the camera which is mounted on the opposite side of the reflecting glass to get a clear view of the reader in front of the teleprompter system. The industrial standard for a beam splitting mirror is 70:30, which means that the glass is 70% transparent and 30% opaque.
A presidential teleprompter system is the one which is used to deliver live speeches and presentations. This version of teleprompter system has got its name because of its being used for the first by the president of America, Mr. Barack Obama. Its general model consists of two separate beam splitting mirrors mounted over an electronic screen with the help of a telescopic stands. The two glasses are pivoted just above the screen at an angle to reflect the script on the bottom screen. These screen and glass units are placed at a distance from each other on both the sides of the speaker and facing the opposite sides of the glasses to the audience. The glasses just like the studio teleprompter is transparent from the audience side to prohibit any script to be viewed by the audience. With the help of a software and hardware setup same scripts is scrolled on both the screen simultaneously at a fixed pace so that the reader can look both the sides while reading the script.
The first teleprompter system was produced by the Teleprompter Corporation, USA in the early 20th century. During 1950s the teleprompter used printed scripts to reflect the script on a slab of thin glass for reflecting the script. The early use of teleprompters was for creating television entertainment. In those days the cameras for recording were placed either below or above the teleprompter system. In 1954 Dwight Eisenhower was the first President to use a teleprompter for a State of the Union address. Even after subtle advances in teleprompters, the printed pieces of papers continued to be used till 1970s. The first computer-based teleprompter system came into existence in 1982.

These lessons can be made available to the students inside the classroom or it can be shared online for them to refer the missed classes.
Continuous evolution in the field of information technology various new techniques of delivering information came into existence such as 3D imaging, augmented reality, virtual reality, etc. Glass teleprompters may be replaced by such technologies in the coming days. But the use of glass teleprompters would remain inevitable due to its portability and economic nature. The coming advancements in the information delivery may incorporate some or all the features of traditional glass teleprompters.
