Interacting in immersive virtual reality is a challenging and open issue in human-computer interaction. Here, we describe a system to evaluate the performance of a low-cost setup, which has not the need of wearing devices to manipulate virtual objects. In particular, we consider the Leap Motion device and we assess its performance into two...

The 3D structure of a virtual or augmented scene is affected by distortions that can affect the natural fruition of the experience. Here, we consider the distortions of the spatial layout of virtual scenes, specifically the underestimation of egocentric distances, as experienced by users.The aim of our work is to develop a computer vision based...

The depth cue is a fundamental piece of information for artificial and living beings who interact with the surrounding environment in order to handle objects and to avoid obstacles: in such situations, the disparity patterns, which arise when agents fixate objects, are vector fields. We propose a biologically-inspired computational model to...
