Aperture based selection for immersive virtual environments
Andrew Forsberg, Kenneth P. Herndon, Robert C. Zeleznik · 1996
We present two novel techniques for effectively selecting objects in immersive virtual environments using a single 6 DOF magnetic tracker. These techniques advance the state of the art in that they exploit the participant's visual frame of reference and fully utilize the position and orientation data from the tracker to improve accuracy of the selection task. Preliminary results from pilot usability studies validate our designs. Finally, the two techniques combine to compensate for each other's weaknesses. KEYWORDS: interaction, selection, immersive virtual environments, direct-manipulation, 3D widgets. INTRODUCTION Selection techniques indicate to an application which object or objects a participant wishes to interact with in a virtual environment (VE). We present two novel techniques for selecting objects in a VE called aperture and orientation. The techniques apply to our test application, an immersive VE for visualizing a computational fluid-dynamics dataset in which users selec...
