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

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

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 ...

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 ...

Context Aware, Multimodal, and Semantic Rendering Engine

Patrick Salamin

Nowadays, several techniques exist to render digital content such as graphics, audio, haptic, etc. Unfortunately, they require different faculties that cannot always be applied, e.g. providing a picture to a blind person would be useless. In this thesis, w ...

Restez à l'écoute! un transcodeur automatique de flux RSS

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

L'utilisation des agrégateurs de news est devenue très commune bien qu'ils requièrent de l'utilisateur qu'il soit devant une écran. Malheureusement, la plupart des gens ne possèdent pas d'écran (ou alors de très petits) lorsqu'ils se déplacent. De plus, ce ...

Intelligent switch: An algorithm to provide the best third-person perspective in augmented reality

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Augmented reality (AR) environments are suffering from a limited workspace. In addition, registration issues are also increased by the use of a mobile camera on the user that provides a first-person perspective (1PP). Using several fixed cameras reduces th ...

Stay Tuned! An Automatic RSS feeds Trans-coder

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

News aggregators are widely used to read RSS feeds but they require the user to be in front of a screen. While moving, people usually do not have any display, or very small ones. Moreover, they need to perform actions to get access to the news: download a ...

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 ...

Two-arm haptic force-feedbacked aid for the shoulder and elbow telerehabilitation

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

In this paper, we present a telerehabilitation system aiming to help the physiotherapists for the shoulder and elbow treatment. It is based on a two-arm haptic force feedback to avoid excessive efforts and discomfort with the spinal column. This system, re ...

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 ...

Advanced Mixed Reality Technologies for Surveillance and Risk Prevention Applications

Daniel Thalmann, Frédéric Vexo, Patrick Salamin, Renaud Ott

We present a system that exploits advanced Mixed and Virtual Reality technologies to create a surveillance and security system that could be also extended to define emergency prevention plans in crowdy environments. Surveillance cameras are carried by a mi ...

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 ...

The Benefits of Third-Person Perspective in Virtual and Augmented Reality?

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Instead of the reality in which you can see your own limbs, in virtual reality simulations it is sometimes disturbing not to be able to see your own body. It seems to create an issue in the proprioperception of the user who does not completely feel integra ...
