From the supplier: Projection systems, which differ from overhead projectors, interface directly with a computer, which enables the system to display text, graphics, animation, and more. The three types of machines used for video/data projection are light-valve projectors, LCD-based projectors, and CRT-based devices. An example of a light-valve projector is the Talaria LV8000 MP Data/Video Projector from General Electric. Sharp Electronics’ XG-1500U is a ceiling-mounted LCD projector. Rear projectors are self-contained units that are suitable for teleconferencing, distance-learning programs, audio/visual presentations, and CAD/CAM applications. LCD units can be used to display computer images, permitting the entire class to learn how to use computer software or write computer programs. There are specialized products such as Dukane’s MagniView 822, which is a combination of an LCD panel and overhead projector designed specifically for education, and Sayett Technology’s MEDIASHOW Color Data Projector. Accessories include In Focus Systems’ LiteShow II, a portable unit, Chisolm’s Color Writer, a color electronic chalkboard, and Proxima’s Cyclops, which permits instructors to stand at the front of the room and work interactively with the application software. These new systems permit classes of any size to see computer-generated lessons and lectures. Citation DetailsTitle: Projection systems: projectors to panels, choices abound.
