GRAVIR / IMAG-INRIA
History (since 2002)
• Bi-annual ‘Engineering Week’ of INPG
– Less students choose science
– Public : highschool students (~15 years old)
– Goal : discover research and engineering
– How : 1 week of tutorials
• MobiNet Tutorials
– GRAVIR / IMAG-INRIA
Mobinet: Interactive simulation software
• Put theory into practice
– develop intuition
– introduce scientific, engineering approach
• Try, understand and learn
– accessible, easy to use
– no fear of making mistakes
• Develop team work
– networked simulation space
MobiNet approach
• Experience notions, visually !
MobiNet approach
• Model of real world
x : x+1
– Object’s state variables (x)
 mathematical model
– Object’s motion (x : x+1)
 physical model of behavior
• Nothing magic !
