Activity Theory Applied to the Desktop Metaphor

Abstract

Although the desktop metaphor is still the de facto in desktop computing, many problems and limitations have been recognized over the years. Although there are many novel approaches that try to solve these problems and limitations, no valid alternative for mainstream usage has yet been presented. In this thesis, we propose to reframe the desktop metaphor by using activity theory. Activity theory is a descriptive framework that rejects the human processor loop and redefines human activity in a broader context by including cultural, historical and social factors. Based on the principles of activity theory, a set of guidelines were deducted that are used to support our proposal for the reframe of the desktop metaphor, co-Activity Manager. co-Activity Manager is a Windows based window manager that allows users to reorganize applications, resources and services in an activity-based approach.
