Abstract
Computer-generated pictures of ‘graphics’ encompass representations as diverse as simple diagrammatic line drawings and multi-dimensional abstract concepts. The suitability of any generator type for different styles of picture and hence application is discussed briefly. Industrial process plant is identified as that area in which graphics will have a major impact in the near future; there are similarities in needs for data display, with common problems, across an industry-wide market sector; the introduction of supervisory control schemes will necessitate abstract concepts requiring envisualis-ation for judgments to be made by non-technical staff. Techniques in the presentation of data trends for production performance and of process stale variables require more research and case study work to be undertaken, as illustrated by reference to the steel industry in this review. The case for theoretical studies in perception at this level of picture complexity is made; the argument for case studies in cooperation with technical management, however, is presented as being more applicable to perceived industrial needs at present, especially in the absence of a theoretical framework within which to treat ‘graphics’.
