This study takes up the problem and the importance of human psychological responses in the development of computerized man-machine interface systems, a point of view which has often been overlooked in the development of such devices. One type of man-machine interface system currently under development involves methods for inputting oral Japanese. The authors examined how "familiarity" with a system might affect the operators' psychological attitudes which, in turn, could influence the physical aspects of the system. In doing so they found (1) interactions between the physical aspects of the system influence the users' feelings of familiarity, and(2) each physical factor does have a critical area in which it exerts an influence upon the operators' feelings of familiarity. Therefore, the authors conclude that the influence of the physical aspects of these systems upon human psychological responses must be taken into consideration when developing man-machine interface systems and that developers and designers must realize that the relationships between the physical aspects of the system and the users' psychological responses are not linear in nature.
