This is something that we all notice but never wondered why. We all are accustomed of listening to speeches from podiums or stands but never questioned the significance of the glass stands which are placed besides it.
Theose glass stands are called a ‘Speech Teleprompter’. This device is behind all the mighty speeches which give us goosebumps. This is a 15″ flat panel color LCD monitors set low and horizontal facing up in a way that angled transparent beamsplitter glass reflects the text into the view of the presenter.
The audience usually just sees the top of the stand and a clear piece of glass and yet the readers can read their entire speech on the teleprompter without the appearance of reading.
This device which works as a savior was designed by Hubert Scholarly in 1955. It was needed to be made because many several commercial actors had a problem memorizing innumerable lines in limited time. After the invention of teleprompter, it was widely used in news programs, talk shows, presidential speeches and video advertisements.
These days personal teleprompters are also being used in schools to deliver pre-written information by novices.
The best benefit that you get from this device is that you control the pace and it avoid the noise of papers while speaking on a microphone. This device is also mostly seen being used during TedTalks.
