I recently received my PHD in HCI and Robotic from Sorbonne Université. My research interest are in the field of robotic, haptic and virtual reality. I aim at improving interaction in VR with a mutlimodal approach.

I mainly focus on Visio-haptic illusion in VR. These illusions introduce a subtle shift between visual representations and haptic stimuli. When this shift is well controlled, the perception from the visual modality tricks the brain and modifies the haptic perception of the physical event. However, when this shift is too large, users detect the illusion, which negatively impacts presence in the virtual scene.

In my thesis, I revisited visio-haptic illusions by taking as a case study the illusion called “hand redirection”. I sought to better understand and model illusion detection with a cognitive approach.
