Dr. Alissa Antle
Concretizing IdeasTransforming theoretically derived ideas to concrete features in a research prototype requires iterative design.

THEORYPhysical experiences of balance concepts of balance
PROTOTYPE Social Justice: balance in food production
DESIGN
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.

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 representationsEd. 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
