Concretizing IdeasTransforming theoretically derived ideas to concrete features in a research prototype requires iterative design. DESIGN THEORY Physical experiences of balance concepts of balance Interface DESIGNInteraction PROTOTYPE Social Justice: balance in food production
Experimental ResearchPrototype is a research instrument that supports investigation of the effect of the concretized theory on human interaction.
Design Research Combines design through research with experimental methodologies to produce two forms of knowledge. • Science -- Search for evidence: Does this concretized idea benefit human use of some form of computation? • Design -- Search for guidance: How do you get the idea into the computation?
ACM ConferencesSupport publication of both forms of knowledge creation. Tangible, Embedded & Embodied Interaction (TEI 10) www.tei-conf.org/10 Designing Interactive Systems (DIS 10) www.dis2010.org
Idea of Design (?) • Herbert A. Simon: …devising courses of action aimed at changing existing situations into preferred ones • J. Christopher Jones: …initiating change in man-made things • C. Alexander: …the process of inventing physical things which display new physical order, organization, form, in response to function • Horst Rittel: …structuring argumentation to solve “wicked” problems • Donald Schön: …a reflective conversation with the materials of a design situation • PelleEhn: ...a democratic and participatory process • J. Rasmussen and K. Vicente: …creating complex sociotechnical systems that help workers adapt to the changing and uncertain demands of their job • W. Visser: …construction of representations Ed. Morgolin and Buchanan (1996)
Computational Design:…tackles ‘design’ as computable ‘problems’ • Understanding ‘cognition’ and ‘activities’ during design • Modeling ‘design’ acts • Developing frameworks and building tools to support the process Example: Transition from higher- to lower-levels with GMEA
