Different kinds of presenters
We can change slides by pressing the arrow keys on the keyboard to go forward or backward in slides. So every time you want to change a slide, you have to go toward your laptop and press the button of the arrow keys. It’s not very professional of course. So it’s best to use presenters.
Imagine you have to walk to the computer, press the button and go back to the place you were standing.
Another horrible method of changing the slide is when the speaker says the next slide, please. Someone is sitting behind the computer and the speaker must ask him to do this: next slide, please.
Some other people use a wireless mouse. It’s a better way but we have to remember that it has its disadvantages. For example, it’s not pretty and professional to keep a big object in our hands all the time.
Also, the range of the wireless mouse is limited. They are made to be used in a short distance so we can’t go too far.
Another way is smartphones.
One other difficulty is that cell phones are big and distracting. Usually, when we have a cell phone in our hand while presenting, the audience would think we don’t pay much attention to them. The audience will feel uncomfortable when you have a cell phone in your hand.
Another way is smartwatches. Depending on what kind of watch you are using; you can change the slides. This way is cool but I don’t recommend it because it is not professional. It can be a backup plan.
Another way is professional presenters or clickers.
As you can see here, they have a receiver which connects to your laptop. There are forward, backward and laser buttons existed on is. This one is for Targus company and this is for Logitech, its receiver is here. It splits in here; it has on and off button, laser and battery. Each one has some buttons. For example, you can change the volume here as well.
Finally, I want to introduce the best option.
Logitech company has provided the best presenter called the spotlight.
As you can see here. It’s professional, it only has three buttons but all I am doing right now, I mean moving the bright circle here and all is with this presenter. The price is about 150$ and sometimes maybe cheaper. Even if you lose this dongle, you can connect to the laptop with Bluetooth. It can be charged by USB and it’s perfect. ((In the next video I tell you how to work with it and change its setting.))
Pros and cons
Now it’s time for the problems that presenters cause.
Let me tell you some of my stories about presenters and the things that happened to me to make it clear.
First, the distance between the presenter and the laptop was too much that I practically couldn’t even use it. In this seminar, they couldn’t put the laptop on the stage and it was at the end of the hall, so my presenter didn’t work well. I couldn’t work correctly with my presenter and I couldn’t easily change the slides. Considering the distance between the sender and receiver is essential.
Another problem happened to me in a seminar with almost two thousand participants. It was an international seminar. We had interpreter devices and their waves interfered with my presenter. My laptop was exactly here and I was there, maybe about two meters away but the presenter didn’t work well because of the wave interference. The moment people went out, the presenter worked but not otherwise. So we have to be careful about these events.
