Unified gesture-based interaction techniques for object manipulation and navigation in a large-scale virtual environment

Manipulation of virtual objects and navigation are common operations in a large-scale virtual environment. In this paper, we propose a few gesture-based interaction techniques that can be used for both object manipulation and navigation. Unlike existing methods, our techniques enable a user to perform these two types of operations flexibly with a little practice in identical interaction manners by introducing a movability property attached to every virtual object.
