Concretizing Ideas Transforming theoretically derived ideas to concrete features in a research prototype requires iterative design. Interface DESIGN Interaction THEORY Physical experiences of balance  concepts of balance PROTOTYPE Social Justice: balance in food production DESIGN

Experimental Research Prototype 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 Conferences Support publication of both forms of knowledge creation. Tangible, Embedded & Embodied Interaction (TEI 10) Designing Interactive Systems (DIS 10)

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 Pelle Ehn:...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’ Example: Transition from higher- to lower-levels with GMEA Understanding ‘cognition’ and ‘activities’ during design Modeling ‘design’ acts Developing frameworks and building tools to support the process

Information refinement is not strictly hierarchical MEA needs to be extended to allow for cycles: one means can satisfy different ends Generalized MEA (GMEA) captures this process Hierarchical ModelProposed Model mission goals objectives concepts (a) level 1 level n level 2 level 3 level...
