Abstract

Virtual Reality (VR) generates realistic visualization and sensation applied to various practices. A Virtual Museum (VM) is a use case where VR may be applied to convince museum visitors to participate with a story told through digital content. Recently, immersive VR technologies have been intensively developed providing a lot of devices which support interactive VM applications. In development of interactive VM, interaction always depends on the selected device. Then content is tuned to fit specific device capacity. Major development must be addressed again whenever the virtual environment is adapted to a new device. This paper proposes a storytelling framework to assist designing interactive content which is device independent. Our framework provides a highlevel abstraction of story and interaction with it which is then translated to any low-level device. A storytelling model and an interaction model are introduced to create a common language for story making. It works with the Viewer, the Asset manager, the Event editor, and the Timeline to organize virtual environments and assign interactions. An example of interactive content design on our framework is presented to demonstrate the development process. We defined three interaction systems: a 2D system, a 3D system, and a CAVE system with interaction techniques based on the interaction model. The storytelling platform has the ability to change interaction systems as required on the same story, allowing us to study the use of different interaction system on VM applications.
