Research Overview

There is a limit in the human's 'cognition-decision-operation' capabilities, which vary on the human internal state, to utilize the current technologies that continue to develop dramatically in our daily lives such as distributed sensors, signal processing, recognition/understanding, databases, information systems, etc. The 'over-reliance' state occurs if there is any conflict between the system and its capabilities expected by humans. For example, system optimization that minimizes human intervention of the system while performing leads human to a state of being too reliant on the system; this significantly reduces the human's 'cognition-decision-operation' capabilities. This state prevents the system capabilities from having much faith in human, even for a small amount, and as a result the entire system may behave differently from the human's intent. As the social significance of the information system growing, the 'over-reliance' leads to unexpected incidents and accidents, and becomes a threat to a safe and secure society. Therefore, the perspective of 'over-reliance' is necessary for a future in which humans live in harmony with information environment. In this project, we study a modeling framework that incorporating the 'cognition-decision-operation' characteristics of human behaviors, and establish a method for detecting 'over-reliance' from the observed behaviors so that the 'over-reliance' of the information system technology will not happen.
