Direct 3D interaction with smart objects
Marcelo Kallmann, Daniël Thalmann · 1999
Performing 3D interactions with virtual objects easily becomes a complex task, limiting the implementation of larger applications. In order to overcome some of these limitations, this paper describes a framework where the virtual object aids the user to accomplish a pre-programmed possible interaction. Such objects are called Smart Objects, in the sense that they know how the user can interact with them, giving clues to aid the interaction. We show how such objects are constructed, and exemplify the framework with an application where the user, wearing a data glove, can easily open and close drawers of some furniture. Keywords Virtual Reality, manipulation, interaction, data glove, virtual objects, virtual environments. 1. INTRODUCTION Virtual Reality (VR) technology has been employed on various different applications, as for example: human factor analysis, navigation in virtual environments, training, visualisation, and design of objects. A common point to all applications i...
