The Benefit of Laser Pointers in Presentations

Laser pointers highlight specific information in a presentation.

Even the most experienced speakers sometimes struggle to engage the attention of large audiences. Laser pointers help presenters direct the viewer's gaze toward the presentation screen, thereby offering a number of benefits.

Function

Laser pointers project a colored dot onto the screen to highlight specific phrases or whole sections of information. The bright dot is visible even from the back of a lecture hall and provides viewers with a colorful focus point throughout the presentation. Laser pointers free the presenter from contact with the screen. The pointer operates from any distance or angle, so you can move around the room and draw attention to material that is too high to reach.

Size

Laser pointers are small enough to be worn on a keychain.

Most laser pointers are small, light and portable, allowing you to deliver a presentation with the minimum amount of fuss. A laser pointer slips easily inside a pocket and can be attached to a key chain.

Warning

Such countries as Australia and the United Kingdom restrict the sale of laser pointers. Some lasers cause retinal damage if pointed directly at the eye, so you should use them with care.
