Grammar based design tools: issues of representation and interaction

  1. 1. Grammar based design tools:Issues of representation and interactionScott ChaseArchitecture, Design & Media TechnologyAalborg Universityscha@create.aau.dkhttp://homes.create.aau.dk/scha/Designing With Vision WorkshopThe Open University, 8 June 2010http://design.open.ac.uk/DV/
  2. 2. Challenge We want conceptual design tools that support designers’ ways of thinking and working and enhance creativity, e.g. offering design alternatives difficult or not possible without the use of such tools. 2
  3. 3. Shape grammars
  4. 4. Grammar applications• Analysis • Grammar construction from a corpus of designs• Synthesis • New grammars of design styles• Transformation • From one design style to another • Change of design brief • Hybrid, crossover designs 5

  8. 8. Grammar computational complexityA33 Darker areas indicate more computational complexity Other factors: •Symbolic/semantic information •Composite representationsA00 Parametric shape String grammars Set grammars Shape grammars grammars grammars) (graph grammars) (shape schema

  10. 10. Grammar use & interaction Design evaluation Grammar evaluation Grammar transformation
  11. 11. Issues for computer implementation• Maximal element representations create huge computational issues (e.g. combinatorial explosion)• Designer interaction with such systems is a challenge • e.g. how to present all possibilities to the designer
  12. 12. Common implementation restrictions• ‘Toy’ systems, e.g. proof of concept• Single design application, hard coded• Representation restrictions, e.g. set grammars, raster representations• Design restrictions, e.g. orthogonal designs onlyDo these restrictions keep us from moving forward?
