This paper introduces an integrated local surface descriptor for surface representation and
3D object recognition. A local surface descriptor is characterized by its centroid, its local …

We have designed and implemented a vision-based system capable of interacting with
user's natural arm and finger gestures. Using depth-based vision has reduced the effect of …

Many of the virtual reality (VR) interaction devices available to the general public rely on the
use of controllers. However, theses ones generate some usability constraints. Current …

The paper addresses the multiple forms of representation that human gesture takes at
different levels for human computer interaction, ranging from gesture acquisition to …

Natural interaction is gaining popularity due to its simple, attractive, and realistic nature,
which realizes direct Human Computer Interaction (HCI). In this paper, we presented a novel …

We present a system engineering approach for designing Service-oriented Architectures
(SOA) for software applications that use gesture commands. The approach employs …

In this paper, we present a calibration-free head gesture recognition system using a motion-
sensor-based approach. For data acquisition we conducted a comprehensive study with 10 …

In this paper, the quality of the interaction of users with a 3D game using different modalities
is studied. Three different interaction methods with a 3D virtual environment are considered …

Au cours de nos travaux, nous nous sommes intéressés à l'apprentissage de gestes
techniques en environnement virtuel. Ces environnements permettent en effet de se former …

This thesis provides an approach on facilitating the analysis of nonverbal behaviour during
human-human interaction. Thereby, much of the work that researchers do starting with …
