Fujita, Yushi, Yanagisawa, Ichiro, Sakuda, Hiroshi and Kiyokawa, Kazuhiro (1995): Using Simulated Human Model for Evaluating Human-Machine Interaction. In: Proceedings of the Sixth International Conference on Human-Computer Interaction July 9-14, 1995, Tokyo, Japan. pp. 945-950.

“Human-machine system can only be understood correctly when it is treated as a joint system. Neither humans nor machine can determine its performance in isolation. It is the interplay between humans and machines that determines the performance. Hence, it is a prerequisite to look into context-driven interactions between humans and machines when attempting to evaluate human-machine systems. Because of the dynamic nature of the interactions, experimental approaches have widely been used for the analysis of the interactions. However, they tend to be associated with a number of practical constraints that sometimes make them difficult to apply. As a supplemental means, simulated human models can be utilized as a useful tool for analyzing the interactions. Cognitive and Action Modeling of Erring Operator (CAMEO) is such a human model which features its ability to simulate some typical erroneous tendencies associated with cognitively demanding tasks such as nuclear power plant operation. This paper describes the technical foundation of CAMEO.”

Watanabe, Osami, Takaura, Katsuhisa, Fujita, Yushi and Hayashi, Yoshio (1995): Evaluation of Ecological Interface Design. In: Proceedings of the Sixth International Conference on Human-Computer Interaction July 9-14, 1995, Tokyo, Japan. pp. 977-982.

“It has increasingly been recognized that operators working in a highly automated large-scale human-machine system may be exposed to cognitively demanding situations in unanticipated emergency. A new display design called ecological interface design (EID) is proposed by several researchers, which they claim is supportive especially in such difficult situations. The EID features model-based parameter selection and graphic presentation, which fit the cognitive characteristics of operators. This paper presents the results of a comparative evaluation of an EID display.”

Sanquist, Thomas F. and Fujita, Yushi (1989): Protocol Analysis and Action Classification in the Evaluation of an Advanced Annunciator System Design. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1064-1067.

“The use of protocol analysis and behavioral classification for evaluating advanced display concepts is described. Three experienced nuclear power plant operators solved problems in a full-scale simulator which employed an alarm suppression logic in the annunciator display. Verbal protocols and behavioral actions were collected as operators solved the problems, and were compared with protocols in which the alarm suppression logic was not used. The results indicated that more observations of discrete values and more control actions were made in the condition employing the alarm suppression scheme, suggesting more effective diagnosis and control with this type of man-machine interface.”
