Precautions while using Overhead Projectors
If a point requires several minutes of discussion, turn off the overhead projector to focus the audience attention on you and away from the screen. Turn the overhead projector back on when youre ready for the next bullet topic. Use this same tactic when you move transparencies across the glass. If the projector is not turned off when you exchange transparencies, a bright light projects on the screen, which causes a distraction. Consider using white borders around the transparencies. These fit around the transparencies and can be purchased in office supply stores. The border provides a place to write notes, and numbering the bordered transparencies keeps the presentation organized. Use a table for the projector that provides enough room for transparencies on both sides of the projector. One side holds the yet to be presented transparencies; the other side holds the completed transparencies. This keeps the presentation flowing smoothly and adds a touch of professionalism.
