Tangible viewpoints

Abstract

We present a multimedia storytelling system that couples a tangible interface with a multiple viewpoint approach to interactive narratives. Over the centuries, stories have moved from the physical environment (around campfires and on the stage), to the printed page, then to movie, television and computer screens. Today, using wireless and tag sensing technologies, storytellers are able to bring digital stories back into our physical environment. The Tangible Viewpoints system explores how physical objects and augmented surfaces can be used as tangible embodiments of different character perspectives in an interactive tale. These graspable surrogates provide a direct mode of navigation to the story world, a means of bridging the gap between cyberspace and our physical environment as we engage with digital stories. The system supports stories told in a range of media, including audio, video, still image and text.In this paper, we first provide a context for Tangible Viewpoints based on research in the areas of tangible interfaces and interactive narratives. We then offer an overview of the Tangible Viewpoints functionality, and explain the design and implementation of the system. The current system has been used in two storytelling projects. We discuss each one, and look at how user feedback has affected or will affect further development. We conclude by suggesting several future applications for the Tangible Viewpoints interface.
