Display terminals should facilitate man/computer communications. In choosing a terminal, the overriding need is to weigh the characteristics and potentialities available so as to maximize the satisfaction of the operator's requirements. The operator wants to create, view, and manipulate such objects as text, line drawings, and natural scenes. He wants to perform these manipulations through natural and direct actions and expects the terminal to be responsive to needs, textual, graphic, or other. Further, the operator wants his terminals large, mobile, legible, reliable, accessible, and cost-effective. This report summarizes the functions and characteristics of several terminal technologies. It also describes a broad sampling (about 30) of existing terminals, citing their widely varying capabilities, their components, their accessories, their applications, and their approximate costs.
