VR edutainment materials platform for elementary dynamics experiment with HI input devices

They attempt to use VR simulation for physics education in high school to supply lessons with alternative opportunity of experiment. We also proposed Interlude framework for VR simulation teaching materials for various dynamics experiment integratedly. Interlude offers user-interface with high experiential impression. We also propose a common platform Prelude to construct various Interlude materials efficiently. Prelude offers execution interface for device control and component library for microworld and presentation as Java API. We discuss feature of HI input devices and adaptation for 3D operation. We develop the device control package in the Execution Interface. The package has several functions of initialization of data extraction and unification, in synchronized control of HI input devices. We make a simple VR viewer as an application using Prelude. We report trial experiment for user´s operability.
