  1. 1. Usage-centered design of adaptable visualization services. Application to cooperation support services system in the AEC sector. Sylvain Kubicki1 and Gilles Halin2 1Public Research Centre Henri Tudor, Luxembourg 2Research Centre in Architecture and Engineering (CRAI), France
  2. 2. Overview  Introduction −  Service innovation in construction sector  Adaptable Visualization Services (AVS)  Usage-based AVS design  A first case study  Conclusion February 17, 2010 IESS 1.0 2010
  3. 3. Introduction Service innovation in Architecture, Engineering and Construction (AEC) Sector February 17, 2010 IESS 1.0 2010
  4. 4. Specificities of the AEC sector   Building life-cycle overview Planning Design Construction Use “Ray & Maria Stata Center for CIIS, MIT”   Main characteristics of the construction Arch. Gehry Partners sector −  Only one object produced −  Short-lived teams −  Independent and heterogeneous actors −  Wide range of models and methods   More and more viewpoints −  Restricted areas of responsibility −  Internal strategies vs. project strategies Dresden station, Germany Arch.

  5. 5. Cooperation between actors   Cooperation is essential −  To ensure project success −  Difficulties ●  Low predictable environment ●  Communications not standardized −  Groupware solutions remain under- used   Service-based innovation −  Cooperation support business services −  Sustainable Service Innovation Process S2IP Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  6. 6. Sustainable Service Innovation Process - S2IP   Developed in CRPHT Luxembourg −  Applied to Business Services design in construction sector: Build-IT project [Kubicki et al. 2009] −  In partnership with CRTI-B (a professional standardization organization) Service

LNCS 5565, pp. 319–333, 2009. IESS 1.0 2010
  7. 7. Service value related processes   Focus on experiments of Business Student project Services −  Real construction projects (pilot-projects) −  Aims ●  Validating business services design Student project ●  First step of a sectorial change management ●  Standardization (practices + services)   Other results School – Luxembourg Cents −  Basic Human Computer Interfaces: −  Interviews have shown that visualization has to be adapted to its users… and their particular needs Offices/Hotel– Luxembourg Kirchberg Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  8. 8. Part I Adaptable Visualization Services February 17, 2010 IESS 1.0 2010
  9. 9. Viewpoints and visualization Current visualization modes Emerging visualization modes Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  10. 10. The concept of usage  Users needs related to −  Their role in the cooperative activity •  e.g. in AEC: architect, engineer, owner of a building… −  Available business services in the collective project  Example of usage: architect need − Searching for specific documents in order to check their consistency with main architectural plans  Defining usages − …As guidelines in User Interface (UI) design Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  11. 11. Usage centered UI design  Usage centered [Constantine & Lookwood 2003] −  Software Engineering approach −  Task oriented −  Based on a collection of models −  Incremental design with interconnected models Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  12. 12. Adaptable and adaptive UI design   In Human-Computer Interface domain −  Adaptable UI can be modified by users −  Adaptive UI changes without explicit intervention of users   Emergent UI design by models −  « To design once and generate many times » −  Modeling different contexts of use (CU) −  Modeling user interface elements evolution −  Based on differents models: CU (user, platform, environment), domain (task, concept), UI (elements)... [Sottet, J. et al. 2006] Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  13. 13. From adaptive UI to Adaptable Visualization Service  Adaptive UI design − Simple user interface − In individual activity situations  UI design for collective activity − Another context : the actor context in the activity − Each actor has his own point of view •  A point of view : a set of visualization modes •  Adapted to different usages − Our approach •  Supporting viewpoint building by usage •  Choosing among a set of Adaptable Visualization Services Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
  14. 14. Adaptable Visualization Service   Visualization services −  Visualize a collection of information −  Remote service offering added value −  Dedicated to a particular scientific domain −  Useful for interpretation of a large volume of data −  In an individual or collective visualization activity   Visualization Service design −  Based on the concept of “dataflow” or “pipeline” •  Data filtering, geometric transformation, image rendering −  Adaptable Visualization Services design is emerging [Hocová, P. et al. 2008] Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
