Laser Pointer Projection Tips:
Laser pointers project a small laser beam that can be used to point out things across a long distance. They are often used as a joke by many people, but they can also be used to help out in projections and slide shows for business or education. Using laser pointers during projections of slides or other material requires proper use of laser pointer safety.
Watch the Brightness
Use Circular Motions
One mistake is to point the laser directly at the spot to be highlighted. This can make the spot it more difficult to see. This is especially true if the important information is spread over a larger area.
Instead of pointing at each individual spot, make circular motions around the perimeter of the pertinent information. This clearly delineates where the important information is without obscuring it. Aim the laser pointer directly at a spot only if you are pinpointing one piece of text or picture. Place the light of the laser just underneath where you want to point.
Don't Overuse It
Laser Pointer Safety
Laser pointers might be relatively weak, but they can still cause damage to the eyes. For example, even a 5 mW laser pointer can be seen more than 22 miles away, especially when it is shined into the sky, according to the Laser FX site. During your projection you will be much closer to the people in the room. For that reason, you should always have your laser pointer turned off when you're not using it. You should also be careful not to point it at any shiny objects. Laser lights can reflect just like any other light, and pointing a laser at a mirror or even awell-polished glass can reflect the laser right into the eye of someone watching your projection.
