WHAT ARE THE DIFFERENT TYPES OF VIEWING MATERIALS?
1. PowerPoint
Microsoft PowerPoint is perhaps the most widely used type of visual aid.
PowerPoint was initially developed to offer graphics for community presentations within corporate organisations, but has been increasingly used in many other collaboration contexts, both in business and beyond. The effect of this much broader use of PowerPoint has been experienced as a powerful transition across culture, with strong responses, including advice that it should be used less, used differently, or better used.
2. Overhead projector slides/transparencies.
(OHP), like a film or a slide projector, uses light to display an expanded image on a wall, enabling the viewing of a small text or a photograph to be viewed with a large audience.
The basis of the image in the overhead projector is a page-sized sheet of clear plastic film (also known as "foils" or "transparencies") with an image to be either printed or hand-written/drawn. They are mounted on the glass plate of the projector, which has a light source below it and a reflecting mirror and a lens assembly above it (hence, "overhead"). Before the invention of video projectors, they were commonly used in education and business.
3. Video (DVD or VHS).
Video is an electronic medium for capturing, copying, playback, transmitting and displaying moving visual media. Video was originally designed for mechanical television systems, which were soon replaced by cathode ray tube (CRT) systems, which were further replaced by many varieties of flat panel displays.
