The document discusses a methodology for modeling the evolution of cultural technologies systems over time using layered and temporally located graphs. Key aspects of the methodology include identifying technical facts and tendencies, representing them as nodes and edges in a graph, and visualizing the graph using a 3D model with axes for time, object type, and technical system or group. The tool would allow users to define a dataset representing these elements and relations, and interact with the visual representation in order to analyze relationships and characteristics of technological evolution.

3. 1.1. Context: t he VHB platform VHB Plateform goals : to help the constitution of industrial projects for contents and services, through full-scale experimentations and the evaluation of those practices; Scientific ressources and expertises : a plan to closely support experimental projects developed by companies; a close watch on the evolution of uses and the evaluation of practices; an observatory on digital services, contents and practices, both present and prospective, on technological, socioeconomic and sociocultural aspects.

4. 1. 2. Objectives Main objective: To design a tool to represent hypothesis about historical evolution of cultural technologies system Challenges: Adopt a multidisciplinary approach Extend the analysis to individual and collective social practices (different systems) Macroscopic analysis and view with different kind of object Basalla, George , The Evolution of Technology , Cambridge University Press, Cambridge,1988) MIT HyperStudio h+digital conference 19/05/2010

5. 2. Methodology Key steps: example : Identify « technical fact » (commutation) Underline « technical tendencies » (decentralisation) Identify edge between « technical systems » (telecom/audiovisuel) Key objects : technical fact (technic related events) technical tendancies (hypothesis relative to technic dynamics) technical system (system of technical fact ) caricature (draw line force of tendancies ) MIT HyperStudio h+digital conference 19/05/2010

6. 3. Model description Graph node > fact > « Technical fact » edge > relation > « Technical tendencies » Matrix X axis > Time > Time Y axis > Object type > Osi system + social Z axis > Group > Technical system MIT HyperStudio h+digital conference 19/05/2010

12. 5. View: mainlines Matching to our data : axe x : Time axe y : Virtualisation / transindividuation axe z: Technical systems Respresentation means: axe x / y : graph in a chart axe z : layerization 3d projection : orthogonal for a better view ! 12/12/10 MIT HyperStudio h+digital conference

13. 5. View : visualization types Combining two representations : - chart (classical, matrix ) - network diagram Using : - layerization concept - orthogonal projection to compare layer ;-) To gain benefits : - 3 view modes to compare data - one unique interface to present data and to edit graph 12/12/10 MIT HyperStudio h+digital conference

14. 6.1. Usage perspective Think about edge qualification (parent, tendances ...) Implement it on a social plateform for history edge analysis Emphasize evolution charasteristics Study innovations ecosystem properties 12/12/10 MIT HyperStudio h+digital conference

15. 6.2. Visualization perspective Tools to analyse time-based multidimensional system Use layerization concept for a time slice extension of classical 2D chart (next step) Manage convergences / divergences of layer (next step) 12/12/10 MIT HyperStudio h+digital conference
