Preface MICA Project Human-Machine Interaction Methodology ResultsThis my activity have been focused on a preliminary study of the human mental errors of industrial operators involved in the control and supervisory of high-risk complex technological systems. It deals with the identification of human mental errors and possibilities of their mitigation through an application of intelligent computer decision support systems. Methodology Heuristic application of the TOGA (Top-down Object-based Goal-oriented Approach) methodology to the problem identification. Application of the IPK conceptual framework to the cognitive operator modelling [http://erg4146.casaccia.enea.it/]. Results An indication and the preliminary analysis of mental functins and tasks which could be supported or executed by IDSSs (Intelligent Computer Decision Support Systems).

Problem Recognition MICA Project Human-Machine InteractionHuman-Machine Interaction is a continuously growing domain of interest of researchers and practictioners. It is a consequence of ever more and more complex technologies and systems controlled and managed by humans. The problem is dedected from the perspectives of : - efficacy and quality of the production - economy and sostenibility , and especially, - safety and reliability of human component in human-machine aggregates.

Problem Recognition MICA ProjectHuman-Machine Interaction MICA Project Problem Recognition Classical engineering paradign: To addopt humans to machine failured in the case of high-risk systems and complex tasks. Problem Recognition Problem Identification Possible solutions Conclusions ...is a classical example of the consequences of a badly designed user interface [Excerpt from the official report to the Three Mile Island nuclear accident] New systemic perspective:” a joint human machine system is performing the task” [E.Hollnagel at al, 94], “Human ignorance is a source of defeates and... human power” © ENEA, A.M.Gadomski,
Problem Recognition MICA Project Human-Machine InteractionPoorly designed user interface causes economical loss: - rejection , - rare using. Badly designed user interface causes catastrofic human errors trough: > confusion, misleading presentation of information, -> misinterpretation, -> cause of dangerous actions. More difficult is to specify what should be implemented than how to do it. We need appropriate goal-oriented models Goal: make communication smoothest possible to interfere least possible with thought process.

MICA Project Systemic Perspective on Reliability and Safety ofHuman-Machine Interaction Systemic Perspective on Reliability and Safety of Human-Machine Interactions (HMI) HMI can be seen as a process. Reliability and Safety can be seen as a two complex properties of HMI and characterized by integrated generalized indicators: Reliability Indicator - R Safety Indicator - Sf The carrier of the HMI process is the coupled system: Human-Machine.

Bases of the Cognitivistic PerspectiveHuman-Machine Interaction MICA Project Bases of the Cognitivistic Perspective "the study of intelligence and intelligent systems, with particular reference to intelligent behaviour as computation" (Simon, H. A. & C. A.

Cognitive Engineering PerspectiveHuman-Machine Interaction MICA Project Cognitive Engineering Perspective the principles of cognitive engineering refers to: user-centered design ( its practices have wide applicability) and human-computer interaction in particular. It is base on cognitive models. Human-computer interaction (HCI) is the intersection between the social and cognitive sciences, on the one hand, and computer science and technology, on the other. HCI researchers analyze and design interaction technologies (e.g., displays and pointing devices, gestures and sketching). They study and improve the processes of technology development (e.g., usability evaluation, software toolkits, cognitive ethnography). Over the past two decades, HCI has progressively integrated scientific concerns with the engineering goal of improving the usability of computers. established a body of technical knowledge and methodology, and contributed broadly to the development of new computer technologies and applications.

Cognitive Technology PerspectiveHuman-Machine Interaction MICA Project Cognitive Technology Perspective Douglas Hofstadter is College Professor of cognitive science and computer science, director of the Center for Research on Concepts and Cognition, Ph.D. in physics, University of Oregon, 1975; Pulitzer Prize. The First International Conference on Cognitive Technology (Hong Kong, 1995) stressed the need for a radically new way of thinking about the impact computer technology has on humans, especially on the human mind. Our main aim at that time was a consideration of these effects with respect to rendering the interface between people and computers more humane.

We need intelligent agents.Human-Machine Interaction MICA Project Possible Solutions Solution: In order to increase human reliability and safety in high-risk complex human-machine systems, we need to shift mental functions from human to computer, to construct computer ever more intelligent. Is it my idea ? We need intelligent agents. ESPECIALLY FOR NOT ROUTINE, MULTI-DATA TASKS UNDER TIME CONSTRAINS.
