Thanks to geolocalized remote control : the sound will follow

Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann

Dematerialized music and MP3 players offer to the user the possibility of carrying his musical content everywhere. However, at home, the music collection is generally not centralized, split between different rooms and audio supports (CDs, MP3s, etc). In th ...

VR haptic interfaces for teleoperation: an evaluation study

Daniel Thalmann, Frédéric Vexo

We present the results of an evaluation study in the framework of user interfaces for teleoperation of vehicles. We developed a virtual cockpit with haptic feedback provided by a Haptic Workstation™. Four alternative teleoperation interfaces were implement ...

Quantifying effects of exposure to the third and first-person perspectives in virtual-reality-based training

Daniel Thalmann, Olaf Blanke, Frédéric Vexo, Patrick Salamin, Ravi Tej Sai Giridhar Tadi

In the recent years, usage of the third-person perspective (3PP) in virtual training methods has become increasingly viable and despite the growing interest in virtual reality and graphics underlying third-person perspective usage, not many studies have sy ...

Wearable Mixed Reality System In Less Than 1 Pound

Daniel Thalmann, Frédéric Vexo, Achille Peternier

We have designed a wearable Mixed Reality (MR) framework which allows to real-time render game-like 3D scenes on see-through head-mounted displays (see through HMDs) and to localize the user position within aknown internet wireless area. Our equipment weig ...

Visualization Learning for Visually Impaired People

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Virtual Environments (VE) are mainly visual experiments that exclude visually impaired people. In this paper we present an application that should allow almost everybody to ``see'' or at least to perceive 3D shapes. We will first describe the mandatory asp ...

Improved Third-Person Perspective: a solution reducing occlusion of the 3PP?

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Pre-existing researches [Salamin et al. 2006] showed that Third-Person Perspective (3PP) enhances user navigation in 3D virtual environments by reducing proprio-perception issues. Nevertheless, this approach has shown drawbacks related to occlusions and ad ...

Comfortable manipulation of a virtual gearshift prototype with haptic feedback

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Improving quality, design and comfort is very important for high technology companies in order to stay competitive against the other enterprises. A present problem is that the new physical dedicated prototypes they need to create for the tests are very exp ...

Wearable Obstacle Detection System for visually impaired People

Daniel Thalmann, Frédéric Vexo, Sylvain Cardin

This paper presents an obstacle detection system for visually impaired people. User can be alerted of closed obstacles in range while traveling in their environment. The system we propose detects the nearest obstacle via a stereoscopic sonar system and sen ...

Practical Design and Implementation of a CAVE Environment

Daniel Thalmann, Frédéric Vexo, Sylvain Cardin, Achille Peternier

CAVE systems are nowadays one of the best Virtual Reality (VR) immersive devices available for rendering virtual environments. Unfortunately, such kind of hardware is extremely expensive, complex and cum-bersome, thus limited in its spread. Several cheaper ...

An Ontology of Virtual Humans: Incorporating Semantics into Human Shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...

Tangible drag-and-drop: Transferring digital content with a remote control

Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann

Despite the fact that dematerialization of all our multimedia content brings advantages, the absence of physical medium brings also a lack of tangibility. This paper presents a gesture-based interface to bring back tangibility in our dematerialized multime ...

Emotional face expression profiles supported by virtual human ontology

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

Expressive facial animation synthesis of human like characters has had many approaches with good results. MPEG-4 standard has functioned as the basis of many of those approaches. In this paper we would like to lay out the knowledge of some of those approac ...

Bridging Geometry and Semantics for Object Manipulation and Grasping

Daniel Thalmann, Frédéric Vexo, Tolga Abaci

In this paper, we present our on-going work towards grasping in an object manipulation context. Our proposal is a novel method that combines a tubular feature classification algorithm, a hand grasp posture generation algorithm and an animation framework fo ...

Providing the best Third-Person Perspective to a Video-Through HMD

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

This paper describes a system with several fixed cameras that provide Third-Person Perspective (3PP) to the video-through HMD of the user. Once done, our system uses an algorithm to make intelligent switches between the different cameras in order to provid ...
