Predicting failures in complex, human-interactive systems is difficult as they may occur under rare operational conditions and may be influenced by many factors including the system mission, the human operator's behavior, device automation, human-device interfaces, and the operational environment. This paper presents a method that integrates task analytic models of human behavior with formal models and model checking in order to formally verify properties of human-interactive systems. This method is illustrated with a case study: the programming of a patient controlled analgesia pump. Two specifications, one of which produces a counterexample, illustrate the analysis and visualization capabilities of the method.

Affordances, or the physical interactions that an environment allows for a particular agent, are critical to the design of human-interactive systems. Researchers are developing formal models of human-device interaction that can be used to verify procedures, displays, and controls; however, no formal approaches to guide design exist for affordances. This paper presents such an approach. To model affordance formally, we instantiate an extant formalism from ecological psychology. A human-environment system model represents physical entities in an environment, properties such as 3-D spatial relations among them, and motor capabilities of a human operator. An application is demonstrated in an aircraft cabin door case study, and verification results aid in identifying an undesirable situation involving door openability.

Arguments to support validity of most contributions in the field of human–computer interaction are based on detailed results of empirical studies involving cohorts of tested users confronted with a set of tasks performed on a prototype version of an interactive system. This chapter presents how the Interactive Cooperative Objects (ICO) formal models of the entire interactive system can support predictive and summative performance evaluation activities by exploiting the models. Predictive performance evaluation is supported by ICO formal models of interactive systems enriched with perceptive, cognitive, and motoric information about the users. Summative usability evaluation is addressed at the level of the software system, which is able to exhaustively log all the user actions performed on the interactive system The articulation of these two evaluation approaches is demonstrated on a case study from the avionics domain with a step-by-step tutorial on how to apply the approach.

A fundamental premise on environmental and behavioral fields involves assumptions about the systematic interrelationships between architecture and patterns of human behavior. The case study conducted was to confirm the needs of specific design methodology in relations to the area of Perception and Human Behavior. The research focused to the extent to which Office Space Performance gives impact on Employee Productivity and Satisfaction. Following that, It was also seen how those affect the behavior of coping. The findings show that there is a significant impact of Spaces’ Performances on Space Satisfaction. Further, there is a significant impact of Space Satisfaction on Coping Behavior and also a significant impact of Spaces’ Performances against Coping behavior. Humanist architecture with architectural behavior approach is required as a Concept of Planning and Architectural Design in the Future. A New Guidelines for Planning and Architectural Design Method for Architectural Design with Behavior concerns is proposed.
