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.

Humans experience the self as localized within their body. This aspect of bodily self-consciousness can be experimentally manipulated by exposing individuals to conflicting multisensory input, or can be abnormal following focal brain injury. Recent technol ...

Self-consciousness has mostly been approached by philosophical enquiry and not by empirical neuroscientific study, leading to an overabundance of diverging theories and an absence of data-driven theories. Using robotic technology, we achieved specific bodi ...

Augmented White Cane with Multimodal Haptic Feedback

Hannes Bleuler, Dominique Chapuis, Simon Gallo, Roger Gassert, Laura Santos Carreras

This paper proposes an instrumented handle with multimodal augmented haptic feedback, which can be integrated into a conventional white cane to extend the haptic exploration range of visually impaired users. The information extracted from the environment t ...

Supplementary motor area and anterior intraparietal area integrate fine-graded timing and force control during precision grip

Dominique Chapuis, Roger Gassert, Etienne Burdet

We investigated the neuronal processing of the physiologically particularly important precision grip (opposition of index finger and thumb) by the combination of functional magnetic resonance imaging (fMRI) and an MR-compatible haptic interface. Ten health ...

2-DOF fMRI-Compatible Haptic Interface for Bimanual Motor Tasks with Grip/Load Force Measurement

Hannes Bleuler, Dominique Chapuis, Roger Gassert

Robotic systems are invaluable tools for the investigation of sensorimotor control of action, as they can influence motion in a controlled manner and precisely record timing, trajectory and interaction forces. In order to better understand the dynamics of ...

Sensors for Applications in Magnetic Resonance Environments

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

This paper analyzes sensing methods compatible with magnetic resonance imaging (MRI) and functional MRI (fMRI) reported in the literature, and presents the three generations of MR-compatible force/torque sensors we have developed for robotic systems to int ...

A hybrid ultrasonic motor and electrorheological fluid clutch actuator for force-feedback in MRI/fMRI

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

This paper presents a safe, electrically powered MR-compatible actuator with a large range of output impedance, which can be used at the entry of the scanner bore. This actuator is composed of an ultrasonic motor (USM) and a torque-controlled electrorheolo ...

A Hybrid Ultrasonic Motor and Electrorheological Fluid Clutch Actuator for Force-Feedback in MRI/fMRI

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

Ieee Service Center, 445 Hoes Lane, Po Box 1331, Piscataway, Nj 08855-1331 Usa2008

In this paper, we describe a biomimetic-fabric-based sensing glove that can be used to monitor hand posture and gesture. Our device is made of a distributed sensor network of piezoresistive conductive elastomers integrated into an elastic fabric. This solu ...
