Overview 2 v Goal + Motivation v Related Approaches v Interaction v Testing + Conclusions v Demonstration v Future Work CEIMVRC 04 Interactive Simulation of Elementary Physical Experiments Alena Kovárová & Silvester Czanner

Goal To create an educational, interactive and multimedia application, which in the same way as our resource book, helped to find and understand relations in physical phenomena. CEIMVRC 04 Interactive Simulation of Elementary Physical Experiments 3 Physics as an Adventure of Cognition Albert Einstein and Leopold Infeld Alena Kovárová & Silvester Czanner

Motivation 4 Children want to play v The real games (physical experiment) + touch v Experiment in our application + possibility to change many other parameters CEIMVRC 04 Interactive Simulation of Elementary Physical Experiments Alena Kovárová & Silvester Czanner
