OBJECT SELECTION IN VIRTUAL ENVIRONMENTS USING AN IMPROVED VIRTUAL POINTER METAPHOR

摘要

In this paper we describe object selection techniques and metaphors for virtual environments (VEs). By combining and extending known techniques, we introduce an improved virtual pointer metaphor which enhances interactive object selection. The extension of the virtual pointer metaphor is based on a bendable ray, which is visualized by a quadratic bezier curve. While a straight ray visualizes the direction of the virtual pointer, the bendable ray points to the closest selectable object. Strategies for determining this object are discussed and compared.
