Double-Volante: Double Cursor Interactions to Move Obstacles for Browsing and Navigation^*

摘要

Based on recently developed 3D computer graphics technology (e.g., hardware and software), there are many Virtual Reality systems and video games with realistic 3D CG. However, navigation methods for browsing 3D scenes have not advanced. Conventional techniques focus on smoothly moving a user's viewpoint around a pre-defined 3D object in a 3D scene. In contrast, our method allows users to move or translate pre-defined objects interactively to clear their fields of vision. In the real world, it is impossible to move big or heavy objects easily, so we think that moving or translating objects is one of the significant advantages of a virtual 3D world. Moreover, by moving pre-defined objects, a user can see objects behind them. By doing this, the user can decide whether to move or not. These simple manipulations are useful not only with 3D navigation but also with information retrieval and web browsing. In this paper, we describe our Double-Volante interaction and its applications.
