Abstract : The failure of present-day interactive graphical systems to provide for an effective relationship between man and machine is examined. An inefficient communications link is shown to be the basis of the problem. The manner in which the user controls program flow and the hardware utilized in inputting commands are revealed as the basic components of communication. Program control is investigated. A revised control method is described which consists of a series of function executions and six basic phases of activity for program control. With respect to input hardware, more human factors analysis is advocated. To assist in this analysis, a function classification system is described. An example test is conducted to compare the relative merits of the light pen with menu, the teletype, and function switches. (Author)
