Presenter - what is it? Presenter is a remote control for switching presentation slides.
What is a presenter for?
It is a well-known fact that most people perceive information best of all visually. Therefore, the use of presentations is a simple and effective way to convey important information to a large audience. Presentations are used at lectures, at various seminars, at meetings, in a word, wherever there are speakers and listeners.
In order for the presentation to be successful, and the public’s attention not to be scattered during the presentation, it is important to switch slides on time and promptly. It is not very convenient to do this with the mouse and computer - you have to be distracted from the audience, concentrate on the switching process, try to remember what I said earlier.
In order to conduct presentations it was easy and convenient, the scientists developed a special remote control for presentations - a presenter. One of the most popular models today is the Logitech r400 presenter.

Advantages and disadvantages of the device
To begin with, let us say that the Logitech r400 presenter is convenient to hold in your hand. Due to the fact that all the buttons on it are of different sizes and shapes, it’s convenient to use it even by touch. When you turn on the device in the computer, the presenter is perceived by the operating system as a keyboard.
To open presentations, it is recommended to use Microsoft Office PowerPoint, and not OpenOffice Impress, because in OpenOffice the screen off button does not work correctly. The slide switch speed depends on the power of your computer.
The presenter's laser pointer works well in rooms without lighting and at a distance of 5 meters. At a distance of 10 meters from the slides and in bright light, the laser indicates objects that are noticeably worse. The battery life of the device is quite large. When using the pointer, the battery charge should last for 20 hours of continuous operation, without using the pointer - up to 1000 hours.
If the batteries are nearly empty, the range of the laser pointer decreases markedly.
The Logitech r400 Presenter is easy to use, comfortable and ergonomically designed.
