Display requirements assessment for command and control systems

The major underlying parameters of a command and control display depend to a great extent upon the basic attributes of the human visual mechanism. The latter are briefly reviewed in order to place the display system requirements in harmony with visual limitations. Resolution, amount of data displayed, display dynamics, coding, and screen size are discussed. Illustrations are given by means of figures and tables of the interrelationship of certain of these criteria. Material is presented demonstrating that display specification and design need not be based upon intuitive judgment, but do have a foundation in sound scientific and engineering principles. The proper parametric designation of the command and control display system can lead to greater effectiveness and overall satisfactory performance
