Limit yourself to three or four different effects during a presentation. When used appropriately, transitions and builds can be effective in keeping the audience's attention. Sound, Animation and Video Sound should be used with discretion. Audio clips, such as whooshing or a slamming door, become tiresome quickly. Animation can be used to show a process, introduce a new topic or open the presentation.
Video is a powerful tool.
It can bring processes to life and take an audience to places they may not have the opportunity to visit. Hardware Electronic presentations use either a LCD panel or projector unit to project the image. An LCD panel is used in conjunction with an overhead projector. To achieve a quality projected image a bright overhead projector with a minimum output of 4,000 lumens and 460 watts is recommended. Keep in mind, an image on the computer monitor can look totally different once projected.
