Activity Theory in HCI: Fundamentals and Reflections by Victor Kaptelinin, Bonnie A. Nardi

By Victor Kaptelinin, Bonnie A. Nardi

Task concept -- a conceptual framework initially built by way of Aleksei Leontiev -- has its roots within the socio-cultural culture in Russian psychology. The foundational proposal of the idea is human task, that's understood as practical, mediated, and transformative interplay among humans and the area. because the early Nineties, task idea has been a visual landmark within the theoretical panorama of Human-Computer interplay (HCI). besides another frameworks, similar to allotted cognition and phenomenology, it verified itself as a number one post-cognitivist technique in HCI and interplay layout. during this ebook we talk about the conceptual foundations of task idea and its contribution to HCI research.
After making the case for thought in HCI and in brief discussing the contribution of task thought to the sphere (Chapter One) we introduce the ancient roots, major rules, and rules of task conception (Chapter Two). After that we current in-depth analyses of 3 matters which we give some thought to of designated value to present advancements in HCI and interplay layout, particularly: business enterprise (Chapter Three), adventure (Chapter Four), and activity-centric computing (Chapter Five). We finish the publication with reflections on demanding situations and clients for extra improvement of task concept in HCI (Chapter Six).

For instance, when an internal activity is externalized, it also affects the individual-collective dimension: for instance, tools and signs employed in externally distributed actions can be shared and thus enable social distribution of the actions. Development. Finally, activity theory requires that activities always be analyzed in the context of development. Development in activity theory is both an object of study and research strategy. As an object of study, development constitutes a complex phenomenon that can be analyzed at different levels.

A ENGESTRÖM’S ACTIVITY SYSTEM MODEL 33 iments over traditional controlled experiments. Formative experiments combine active intervention in the system or processes under study with monitoring of developmental changes caused by the intervention. At the same time, activity theory does not prescribe a single method of study since different types and levels of development require different methods or combinations of methods. The principles of activity theory, described above, comprise an integrated system: they represent different aspects of human activity as a whole.

Third and finally, Leontiev offered a number of more concrete insights about the relationship between mind and activity, most notably the idea of structural similarity between internal and external processes. THE CONCEPT OF ACTIVITY AND THE EVOLUTION OF PSYCHE Leontiev started his professional career by taking part in a large-scale research program initiated and coordinated by Vygotsky. Later on he formulated his own agenda which was an ambitious attempt to provide a theoretical account of the evolution of mind.
