The ability to build and control exposure through a seamless synergy of interaction and narration is a strongly required feature of a new type of immersive-VR training and therapy system. This paper presents a practical approach for immersive-VR training a ...
Virtual reality is gaining on importance in many fields – scientific simulation, training, therapy and also more and more in entertainment. All these applications require the human user to interact with virtual worlds inhabited by intelligent characters an ...
Technological advances of the last decades enabled the development of a set of new medical techniques that differ from traditional open surgery. These techniques, referred to as minimally invasive surgery (MIS), involve complex instruments and imaging devi ...
Crowds are part of our everyday experience; nevertheless, in virtual worlds they are still relatively rare. In this thesis we explore the challenges of bringing crowds into interactive virtual environments and the possible applications of real-time interac ...
We hereby present a study whose aim is to evaluate the efficiency and flexibility of virtual reality as a therapeutic tool in the confines of a social phobia behavioural therapeutic program. Our research protocol, accepted by the ethical commission of the ...
Ultrasound imaging allows the evaluation of the degree of emergency of a patient. However, in several occasions a well trained sonographer is unavailable to perform such echography. To cope with this issue, the OTELO project aims to develop a fully integra ...

This thesis presents researches and experiments performed in collaboration with a psychiatrist in order to validate and improve the use of virtual reality in social phobia psychotherapy. Cognitive and behavioral therapies are strongly based on the exposure ...
In the context of cognitive and behavioural therapies, the use of immersion technologies to replace classical exposure often improves the therapeutic process. As it is necessary to validate the efficiency of such a technique, both therapists and VR special ...
For use in a Virtual Reality based training system for surgical micromanipulation, we have developed a fast multi- scale FEM algorithm that concentrates detail where needed while still handling global deformations. The resulting 6- to 7-fold speed up is pr ...
We are developing a Virtual Reality based training system for micromanipulation in collaboration with the National University Hospital in Singapore. While conventional approaches judge a virtual environment by its resemblance to the real environment, we us ...
