Une infrastructure d'évaluation pour des techniques de représentation de l'information non-géométrique dans les environnements virtuels 3D

Augmenting 3D virtual environments with non-geometrical information improves our understanding of geometrical objects and links between objects in order to perform tasks which require non-geometric information and a 3D scene at the same time. Many interactive presentation techniques have been devised to incorporate non-geometric information into 3D virtual environments. Our main objective is to create an evaluation grid to be used for comparing the usability of techniques according to the information to display, the geometrical context and the task. In this article, we present an evaluation framework that we have developed in order to perform usability tests. These tests will let us fill-in the evaluation grid for the representation techniques of non-geometric information.
