PG software gives you an enormous range of tools, but it also requires new disciplines. Machines are also notoriously peculiar and persnickety, so it's essential to become familiar with the equipment you'll be using yourself. Our discussion here will focus on presenting with a computer rather than printing out to overheads and presenting from acetates placed on a slide projector. Placing Your Equipment Equipment can help a speaker convey a point, or it can literally come between the presenter and the audience. You'll better ensure that your presentations fit into the former category by keeping your back to the screen.
Many presenters make the mistake of watching their own slide shows.
This socks them with the double whammy of losing eye contact with the audience and placing the slideshow at the center of attention. You can avoid both problems by keeping your back to the screen. When you need to refer to screen elements, you can step to the side of the screen, or turn briefly to check whatever it is you need to see. You can see everything that happens on screen without ever having to turn around. People with considerable experience using presentation graphics may be able to cue their own notes off of the screen rather than keeping a separate set of notes for themselves.
