1.1. Context: the 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.


1. 2. ObjectivesMain 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)


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 )


3. Model description

• Graph node > fact > « Technical fact » edge > relation > « Technical tendencies »

• Matrix

X axis > Time > TimeY axis > Object type > Osi system + socialZ axis > Group > Technical system


4. Implementation

The Demo Slide !So we create a tool to define a dataset

and in the same time represent it.

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 !

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

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

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)
