3 Hvad handler Dourish s bog om? 3 Philosophical bases of human-computer interaction. Embodied interaction" - an approach to interacting with software systems that emphasizes skilled, engaged practice rather than disembodied rationality Reflects the phenomenological approaches of Martin Heidegger, Ludwig Wittgenstein, and other twentieth-century philosophers. The phenomenological tradition emphasizes the primacy of natural practice over abstract cognition in everyday activity.

4 Hvad er embodiment? 4 Embodiment: legemliggørelse; inkarnation Embodied Interaction Interaction with computer systems that occupy the world, a world of physical and social reality, and that exploit this fact in how they interact with us. Embodiment: Not a property of systems, technologies, or artifacts, it is a property of interaction. It is rooted in the ways in which people (and technologies) participate in the world. (189) "The Grave", William Blake Wikipedia In essence embodiment as an idea binds two worlds of substance and spirit, contrary to a duality (Descartes). Thus body and mind are fused into a single being.

5 Baggrund 5 Moore s lov antallet af transistorer pr. arealenhed fordobles hvert 2. år computerens kapacitet fordobles hver 18. måned We talk about how fast it is changing, but we talk less about the ways in which it is not. Many things about computers are not changing at all. Our basic idea about what a computer is, what it does, and how it does it, for instance, have hardly changed for decades Nor have the difficulties we encounter actually using computers

23 23 Tangible Computing

24 Bits and Atoms 24 Hiroshi Ishii MIT, Tangible Media Group Tangible Bits: Towards Seamless Interfaces between People, Bits and Atoms (1997)

25 Ishii et al: Bits & Atoms 25 We live between two realms: our physical environment and cyberspace. Despite our dual citizenship, the absence of seamless couplings between these parallel existences leaves a great divide between the worlds of bits and atoms. Although we have developed various skills and work practices for processing information through haptic interactions with physical objects most of these practices are neglected because of the lack of diversity of input/output media, and too much bias towards graphical output

26 InTouch 26 Ishii, Brave og Dahley 1997 Haptic Communication

27 Reality-Based Interaction 27 Reality-Based Interaction: A Framework for Post-WIMP Interfaces Robert J.K. Jacob Audrey Girouard m.fl. BIID Lektion 9

28 Feature of Tangible Computing (Dourish) 28 Physical mappings physical objects rather than abstract entities specificity and specialization Exploiting physical affordances suggesting and guiding action Distributed interaction interaction across a range of objects interaction spread throughout a space moving beyond enforced sequentiality
