Communication between Man and Machine

The inclusion of computer-based assemblies into man-machine complexes has enhanced the relevance of characteristics of the human link in the system. In particular, the virtues and limitations for transmission of information among the physical subsystems through a human channel is an important consideration in systems design. The current status of the supporting research for this area is briefly summarized. The related but more recondite area covering communication between man and computer is also important to the effectiveness of man-machine complexes. However, supporting research for this area is meager and most of it is contained in engineering psychology studies pertinent to the needs of specific systems. Research facilities more appropriate for the exploratory needs of both areas are becoming available and these presage the broad intensive programs needed to provide research guidance to the systems design of man-machine complexes.
