Gain A New Perspective: Towards Exploring Multi-View Alignment in Mixed Reality

Abstract: Traditional MR methods provide virtual guides such as text, arrows, or animations to assist users during alignment tasks. In contrast, this work explores the feasibility of using additional views generated by virtual cameras and mirrors. Presenting additional views from different perspectives can help to mitigate the estimation errors and show information that is not directly visible to users.

Augmented Mirrors

Abstract: Through the integration of a real mirror, our approach is capable to reflect changes in the real and virtual content of an AR application while users benefit from the perceptual advantages of using mirrors. This concept, simple yet effective, only requires tracking the user and mirror poses with the accuracy demanded by a specific application.

Visualization Techniques for Precise Alignment in VR: A Comparative Study

Abstract: This paper presents a comparative evaluation of four static visualization techniques used to render virtual objects when precise alignment in 6 degrees of freedom (DoF^?) is required. The selection of these techniques is based on the amount of occlusion caused by the visual guides during the alignment task. For further details, please contact me: alejandro.martin@tum.de
