Shape Retrieval and 3D Gestural Interaction
(The Eurographics Association, 2016) Giachetti, Andrea; Caputo, Fabio Marco; Carcangiu, Alessandro; Scateni, Riccardo; Spano, Lucio Davide; A. Ferreira and A. Giachetti and D. Giorgi
Despite the emerging importance of Virtual Reality and immersive interaction research, no papers on application of 3D shape retrieval to this topic have been presented in recent 3D Object Retrieval workshops. In this paper we discuss how geometric processing and geometric shape retrieval methods could be extremely useful to implement effective natural interaction systems for 3D immersive virtual environments. In particular, we will discuss how the reduction of complex gesture recognition tasks to simple geometric retrieval ones could be useful to solve open issue in gestural interaction. Algorithms for robust point description in trajectories data with learning of inter-subject invariant features could, for example, solve relevant issues of direct manipulation algorithms, and 3D object retrieval methods could be used as well to build dictionaries and implement guidance system to maximize usability of natural gestural interfaces.
