abstract = {In this paper we investigate suitable 3D manipulation techniques for a new generation of depth trackers exploitable in ego-vision for an immersive virtual environment. After presenting the specific configuration and hardware used, the paper focuses on an investigation into the advantages and disadvantages of the various techniques in order to choose the one most suitable for the manipulation of an object in an immersive virtual environment. We have faced the problem of canonical manipulation which includes, besides the selection, the positioning and rotation. Two different approaches are described allowing respectively a direct or constrained manipulation of the virtual object. Our aim is to evaluate the perceived usability of the two proposed manipulation techniques in the specific configuration and for this reason qualitative data have been gathered using the System Usability Scale questionnaire. The results show a different level of difficulty perceived by the testers between the two canonical manipulation techniques and a general preference for techniques that prove to be less tiring.},

abstract = {The recent availability of low cost wearable displays coupled with contactless motion sensing devices is leveraging the design of immersive and highly interactive virtual environments. In such virtual worlds, the human-computer interface, and particularly the navigation technique, plays a crucial role. This paper presents a preliminary evaluation of traveling constraints in egocentric vision. In more detail, we describe and compare in an ego-vision scenario two travel techniques, both based on a combination of visual controls and hand gestures but proving to be different in terms of the number of travel directions allowed to the user and of the travel velocity control. The experimental results indicate that, despite the users appreciating the possibility of controlling the travel direction with both head and arrows, not all the directions are considered useful in the same way. However, direct control of the velocity proves to affect positively the navigation experience in all the considered scenarios.},
