Why do everyone like to use laser pointers?
Laser pointers are becoming more and more popular. They are only used for lectures and presentations. They like to use optical pointing devices, even children use them. Laser pointers are increasingly used as toys. The Laser pointer (from the English laser pointer) is a light pen that is particularly suitable for presentations with projection. The laser pointer is manufactured in a convenient size, and it is also available in the form of a keychain, a ballpoint pen, or a combination with a remote control (demonstrator). Each presentation software provides exciting opportunities to highlight content. And they are usually very easy to use. Whether it's the red circle surrounding the content, the important content is enlarged, or the unimportant content is grayed out: all these effects are definitely easier to see on any presentation surface than the small red or green dots.

The laser pointer is the index finger of the speaker. And this is where the danger lies. The laser pointer acts on the audience like a pointed index finger or a teacher’s pointing stick. The speaker should avoid two rather negative impressions. In Powerpoint presentations (or other presentations using Prezi and Keynote), the presenter is often used. It scrolls the presentation slides like a remote control. Usually it also contains a laser pointer. So let yourself realize: it is just a tool to support what is said or reduce stage fright, because you can stick to it. But it cannot replace the missing substance.
