Activity Theory as a Framework for Activity Taxonomy in HCI

In this article, the Activity Theory (AT) is analyzed to take it as a basis for the definition of an Activity classification Model of Interactive Systems called: Activity Taxonomy (ATx) for Interactive Systems. Our purpose is to use the ATx for: a. Set discussions about the effectiveness of the artifacts used in software engineering to specify the activity, b. The incorporation of the Human Computer Interaction (HCI) in the processes of software development, c. Definition of the minimum activity classifiers to specify interactive systems that promote HCI, d. Evaluation and integration of languages and/or software development processes, e. Promote normalization of the artifacts used in the specification of software, f. The specification of the execution models of interactive systems. This paper focuses specifically on b, c, d and f.
