Turing machine as an ecological model for task analysis.
A new model for task analysis is presented based on the ecological approach initiated by cognitive work analysis (CWA). This model aims to improve the implementation of the theoretical principles involved in the ecological approach of a work system. More precisely, under current CWA, task analysis u...

This model aims to improve the implementation of the theoretical principles involved in the ecological approach of a work system. More precisely, under current CWA, task analysis uses Rasmussen's ladder. However, this approach fails to highlight the contextual constraints on the task. This model is based on the Turing machine formalism and takes into account the variety of situations that can be experienced by an agent and especially degraded situations of work. Moreover, it can model the concept of affordance-specifying information. It is shown that this formalism can be applied to a prototypical task, such as opening a door. pubtype: Academic Journal doctype: pictorial review tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
