INFORMATION SYSTEMS
1. The future of information systems may be gathered from several areas of current research. As all information carriers (text, video, and sound) can be converted to digital form and manipulated by increasingly sophisticated techniques, the ranges of media, functions, and capabilities of information systems are constantly expanding. Evolving techniques of natural-language processing and understanding, knowledge representation, and neural process modelling have begun to join the more traditional range of methods of content analysis and manipulation. The use of these techniques opens the possibility of receiving new knowledge from existing data.
2. Computer visualisation, a new field that has grown expansively since the early 1990s, deals with the conversion of masses of data coming from instruments, databases, or computer simulations into visual displays - the most efficient method of human information reception, analysis, and exchange.
3. Related to computer visualisation is the research area of virtual reality or virtual worlds, which denotes the generation of synthetic environments through the use of three-dimensional displays and interaction devices. A number of research directions in this area are particularly relevant to future information systems: knowledge-based world modelling; the development of physical analogues for abstract quantitative and organisational data; and search and retrieval in large virtual worlds.
4. Present-day computers are remarkably versatile machines capable of assisting humans in nearly every problem-solving task that involves symbol manipulations. Television, on the other hand, has penetrated societies throughout the world as a noninteractive display device for combined video and audio signals. The forthcoming convergence of three digital technologies - namely, the computer, very-high-definition television (V-HDTV), and data communications - is inevitable. In such a system, a large-screen multimedia display monitor, containing a 64-megabit primary memory and a billion-byte hard disk for data storage and playback, would serve as a computer and, over fibre links, an interactive television receiver.
