Programs include realistic graphics, animation, movement, music, sound, images, text, and digitized realistic voice. VR is loosely defined as putting users into a computer-generated environment, rather than merely reacting to images on a screen. VR has left the hands of philosophers and engineers and has the potential to transform business and society. For years, people have been looking forward to personal computers that could combine text, graphics, animation, sound, music, voice, and video in education, training and business programs. Some computers and some programs used several media, but very few could handle all.
Compression is the answer to storage problems.
MPEG compression compresses similar frames of video, tracks elements which change between frames and discards the redundancies. Each form of media presents information differently and motivates its use. Printed materials encourage scanning, reading as much as is necessary, then making a decision to learn more or go on. Computers tend to present focused information through words, spreadsheets, databases or other kinds of formats. The purpose of multimedia is to combine all of these so that the benefits of each can be used in a desktop environment.
