Developing a Model of Cognitive Lockup for User Interface Engineering
نویسندگان
چکیده
This paper presents the development of a cognitive model of cognitive lockup: the tendency of humans to deal with disturbances sequentially, possibly overseeing crucial data from unattended resources so that serious task failures can appear—e.g., in a cockpit or control centre. The proposed model should support the design and evaluation of user interfaces that prevent such failures, being used outside the academic community. Based on the practical cognitive task load theory of Neerincx (2003), this model distinguishes time pressure and number of tasks-to-do as two factors that increase task switch costs and the corresponding risk of cognitive lock-up. The CASCaS architecture proved to fit best with the requirements to incorporate these factors and to support the UI engineering process.

متن کاملAugmenting Cognition: Reviewing the Symbiotic Relation Between Man and Machine
One of the goals of augmented cognition is creation of adaptive human-machine collaboration that continually optimizes performance of the human-machine system. Augmented Cognition aims to compensate for temporal limitations in human information processing, for instance in the case of overload, cognitive lockup, and underload. Adaptive behavior, however, may also have undesirable side effects. T...
