MHAPTIC : a Haptic Manipulation Library for Generic Virtual Environments

Daniel Thalmann, Frédéric Vexo, Renaud Ott, Vincent de Perrot

This paper presents a new library called MHaptic for bimanual haptic interaction within generic virtual environments. It has been specifically designed to work with a Haptic Workstation. MHaptic provides tools for accelerated development of virtual environ ...

Novel concepts in phase shifting interferometry and their applications to holographic moiré

Abhijit Patil

To date, no phase shifting technique has been implemented that accommodates the requirements inherent in holographic moiré . In the present form of measurement, only the value of one component of difference in displacement carried on moiré is quantified, w ...

Web-based interaction and collaboration in felxible engineering education

Anh Vu Nguyen Ngoc

This research work falls on a multidisciplinary domain, where there is a cross feeding between Computer, Information Sciences and Cognitive Sciences. This PhD dissertation has focused on the interaction and collaboration issues in Web-based experimentation ...

Information-theoretic framework for unsupervised activity classification

Frédéric Kaplan

This article presents a mathematical framework based on information theory to compare multivariate sensory streams. Central to this approach is the notion of configuration: a set of distances between information sources, statistically evaluated for a given ...

Spatio-Temporal Sampling and Distributed Compression of the Sound Field

Martin Vetterli, Emre Telatar, Luciano Sbaiz, Olivier Roy, Thibaut Ajdler, Robert Konsbruck

We investigate how the sound field induced by an acoustic event evolves over space and time. The characteristics of its bidimensional Fourier spectrum are analyzed and spatio-temporal sampling results using an array of microphones are provided for differen ...

Progress of the Architectural Competition: Learning Center, the Lausanne Example

David Aymonin, Mirjana Rittmeyer

Point of entry to the Ecole Polytechnique Fédérale de Lausanne (EPFL), the Learning Center will be a place to learn, to obtain information, and to live. Replacing and improving the old main library, this new building will gradually assimilate all EPFL depa ...

Fountain Capacity

Emre Telatar

Fountain codes have been successfully employed for reliable and efficient transmission of information via erasure channels with unknown erasure rates. This paper introduces the notion of fountain capacity for arbitrary channels, and shows that it is equal ...

Application of Information Retrieval Technologies to Presentation Slides

Jean-Marc Odobez, Alessandro Vinciarelli

Presentations are becoming an increasingly more common means of communication in working environments, and slides are often the necessary supporting material on which the presentations rely. In this paper, we describe a slide indexing and retrieval system ...

Advancing knowledge and the knowledge economy

Dominique Foray

The revolution in information technology transforms not only information and its uses but, more important, knowledge and the ways we generate and manage it. Knowledge is now seen as input, output, and capital, even if imperfectly accounted for or understoo ...

Information Theoretic Combination of Classifiers With Application to Multiple SVMs

Jean-Philippe Thiran, Julien Meynet

Combining several classifiers has proved to be an efficient machine learning technique. Two concepts influence clearly the efficiency of an ensemble: the diversity between classifiers and the individual accuracies of the classifiers. We use an information ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
