Augmented Reality System for the Visualization and Interaction with 3D Digital Models in a Wide Environment
Abstract. Augmented Reality (AR) applications have demonstrated to be effective in the design review phase, when new products have been designed and require to be evaluated. AR offers the possibility of evaluating 3D virtual models of these products in their real context of use. The visualization of and the interaction with 3D digital models in an AR environment requires dealing with devices that can be invasive and uncomfortable and, as a consequence, they cannot be used for a long period of time. These devices have to do with the visualization, tracking and interaction: visualization allows the visual merging of virtual objects in the real environment; tracking creates the temporal and the spatial link between real and virtual objects, and interaction handles the communication between users and virtual objects. The selection and the combination of techniques related to these technological aspects have a significant impact on the performance of the AR system. The aim of the research, presented in this paper, is to develop and evaluate a novel interactive system, which allows the user to comfortably interact with 3D digital models in a wide AR environment by using a specific projection-based display and without the need to wear cumbersome equipment. Starting from these requirements, the authors have developed an AR system based on commercial technologies.
