Interactive context-driven visualization tools for augmented reality

Abstract

In this article we present an interaction tool, based on the Magic Lenses technique, that allows a 3D scene to be affected dynamically given contextual information, for example, to support information filtering. We show how elements of a scene graph are grouped by context in addition to hierarchically, and, how this enables us to locally modify their rendering styles. This research has two major contributions, the use of context sensitivity with 3D Magic Lenses in a scene graph and the implementation of multiple volumetric 3D Magic Lenses for Augmented Reality setups. We have developed our tool for the Studierstube framework which allows us doing rapid prototyping of Virtual and Augmented Reality applications. Some application directions are shown throughout the paper. We compare our work with other methods, highlight strengths and weaknesses and finally discuss research directions for our work.
