You will need a green laser pen to help you.

Laser Pen For Your Laptop

When you use a slideshow, you will use some of your own notebooks or some organizers provided by the conference organizer. In the latter case, there are several drawbacks: 1. The organization will take your presentation as a file, and you can do whatever you need for the file, and 2. The organization's computer may not have installed all the necessary software The demo software may not be updated to the latest version. In particular, video data may be problematic: your video runs on your laptop, not on your organization's computer (it happened to me a month ago). So I always like to use my own laptop. Now the video projector is very smart and can handle Windows and Apple laptops or laptops.

Mouse With Laser

When you browse the slideshow in a presentation, you do not want to bind it to the computer and press the key. So you need a wireless device. The USB mouse seems to be perfect, but they have a drawback because the computer's response to the mouse click is inconsistent. Notoriously, the "back" click does cause the previous slide to be displayed, but a context menu is displayed. Sometimes this behavior can be customized, sometimes not. In the presenter view, sometimes the mouse cursor must be somewhere on the second screen to boot the slideshow.

When you want to point out some of the laser pen on the slide, it is quite convenient. To stand out on the screen, the green laser pen is much better than the red laser pen. However, due to national or European safety regulations, it is becoming increasingly difficult to buy a green laser pen. In addition, on the one hand, the wireless mouse, on the other hand, the huge laser pointer is very inconvenient. Especially when the mouse clicks no desired behavior.

USB Laser Pointer Help Wireless USB presenter

Relatively newer wireless devices solve all of these problems. I mean wireless presenter. You can purchase these products from any e-store, and you can choose between multiple brands. The software (plug-and-play driver) solves the problem of inconsistent mouse clicks. It has a forward and backward button, and on all operating systems, according to the needs of these buttons and the expected response. There is also a built-in laser pen. But unfortunately, in almost all cases, the flash pointer is a red low-brightness laser pen.

But you should not use the red light to the presenter. Just order them in the United States. You can buy in kitlaser, for you to provide a variety of types of laser pen, any of your choice.
