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.
After continuously applying spatially and temporally congruent visuo-tactile stimulation to external, body-like objects, healthy humans feel the fake part to be the origin of the touch sensations and feel it to be their own. Incongruent stimulation nullifi ...
Since [years] we hear about Virtual Reality as a discipline that could potentially provide benefits to many applications. Basically, the principle of Virtual Reality consists in stimulating user senses in order to give the impression to be in another place ...
Abstract: Recent advances in brain-machine interfaces (BMIs) have demonstrated the possibility of motor neuroprosthetics directly controlled by brain activity. Ideally neuroprosthetic limbs should be integrated in the body schema of the subject. To explore ...
Despite the wide amount of computer graphics frameworks and solutions available for virtual reality, it is still difficult to find a perfect one fitting at the same time the many constraints of research and educational contexts. Advanced functionalities an ...
Le projet a pour but de concevoir un gant à retour de force. Ce gant devra agir sur le bout des doigts de l'utilisateur afin de recréer la sensation de saisie d'objet entre ses doigts. Dans une première approche, nous nous focaliserons sur un seul doigt: l ...
A virtual reality system for the training of the lumbar puncture intervention is presented. We use a haptic device with six degrees of freedom (6DOF) to feedback forces that resist needle insertion and rotation. An improved haptic volume rendering approach ...
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 ...
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 ...
We are working towards the development of a robotic hand-held surgical device for laparoscopic interventions that enhances the surgeons' dexterity. In this paper, the kinematics of the end effector is studied. Different choices of kinematics are compared d ...
While feedback of the grasping force is necessary to manipulate objects skillfully, most Virtual Reality systems do not provide such feedback. Grasping an object is often reduced to pushing a button on the interface. This paper presents the design and real ...
