Abstract

Augmented reality environments, where humans can interact with both virtual and real objects, are a powerful tool to achieve a natural human-computer interaction. The recent diffusion of off-the-shelf stereoscopic visualization displays and motion capture devices has paved the way for the development of effective augmented reality systems at affordable costs. However, with the conventional approaches an user freely moving in front of a 3D display could experience a misperception of the 3D position and of the shape of virtual objects. Such distortions can have serious consequences in scientific and medical fields, where a veridical perception is required, and they can cause visual fatigue in consumer and entertainment applications. In this paper, we develop an augmented reality system, based on a novel stereoscopic rendering technique, capable to correctly render 3D virtual objects to an user that changes his/her position in the real world and acts in the virtual scenario. The proposed rendering technique has been tested in a static and in a dynamic augmented reality scenario by several observers. The obtained results confirm the improvement of the developed solution with respect to the standard systems.
