Simulation-based virtual experience: Domino for physics learning

Abstract

Virtual Reality simulation enables immersive 3D experience of a Virtual Environment (VE). A simulation-based VE can be used to map real world phenomena into virtual experiences. This research focuses on the use of Newton's physics law to demonstrate the effects of forces upon object's falling movement, and their effects towards other fallible objects. A reconfigurable simulation enables the users to reconfigure the parameters of the objects involved in the simulation. So that they can see different effects from the different configurations, such as force magnitude and distance between objects. This concept is suitable for a classroom learning of physics law. Preliminary implementation is done on a PC with a joystick for 4DOF movement. The graphics is implemented by SGI OpenGL Performer. A middleware called NAVERLib that consists of Performer's modules for easy XML-based configuration is used for management of visualization, network and devices connection, and where the engine of this domino simulation is attached.
