Augmented Reality System for the Visualization and Interaction with 3D Digital Models in a Wide Environment

ABSTRACT

This paper proposes a new interactive Augmented Reality (AR) system, which has been conceived to allow a user to freely interact with virtual objects integrated in a real environment without the need to wear cumbersome equipment. The AR system has been developed by integrating the Fog Screen display technology, stereoscopic visualization and the Microsoft Kinect. The user can select and manage the position of virtual objects visualized on the Fog Screen display by using directly his/her hands. A specific software application has been developed to perform evaluation testing sessions with users. The aim of the testing sessions was to verify the influence of issues related to tracking, visualization and interaction modalities on the overall usability of the AR ‘system. The collected experimental results demonstrate the easiness of use and the effectiveness of the new interactive AR system and highlight the features preferred by the users.
