multiple aspect based task analysis (mabta) for user requirements gathering in highly-contextualized interactive system design
Many traditional methods in the task analysis area are developed for analyzing the task structure of interactions involving individual users. Nowadays more issues have been raised in dealing with group work task analysis. Accommodating contextual information as a part of task modeling is a potentially fertile arena of exploration in this area. This paper proposes a mechanism, multiple aspect based task analysis (MABTA), as another new way to support a combination of emphasis on context with the method of task analysis, focusing on accommodating multiple aspects of users' group work situation into task analysis. The research goal is to identify and to analyze user interface design requirements through this new mechanism, MABTA. A case study was introduced in order to demonstrate the benefits of this mechanism.
