The cognitive aspects of HCI for GIS are central to an individual’s use of a GIS. GIS is the core of an enabling information technology that has developed within research and applied settings over the last twenty or so years on a world-wide basis. In parallel to the rise of naturalistic decision theory, cognitive science and human-computer interaction (HCI) researchers were developing increasingly powerful analysis methods that collectively were called cognitive task analysis techniques. Generally speaking, a model of a task in a cognitive architecture (generally termed a “cognitive model”) consists of the architecture and the requisite knowledge to perform the specified task. A cognitive task analysis generates detailed, precise information on the nature of expert performance in a specific task of interest. Using CSE, we were able to produce an efficient and effective redesign of the AMACM Weapons Director (WD) station. Universal design 11.

Introduction. Methods of Cognitive Analysis for HCI, CHI'95 Tutorial, Denver, Colorado. That is, cognitive task analysis represents people perform-ing domain tasks using the concepts and tools of their Design rules 8. User support Part Three: Models and Theories 12. These methods can generally be grouped together as task analysis. Cognitive task analysis has implications for the development of expert systems, training and instructional design, expert decision making and policymaking. Just as the cognitive task analysis was proposed to be used in tandem with hierarchical task analyses to account for cognitive components of a task, the current paper proposes a method to account for emotional components of a task. A CTA helps to One way of achieving this is to make use of extensions to the standard H … Cognitive Science.
