I am currently working in SRL group at McGill as a Postdoctoral Fellow. My work involve many aspects of research in haptic.
After obtaining my diploma of engineer from the school of Arts and Metiers, I chose to pursue doctoral studies in haptics and micro-robotics.
This PhD was an opportunity for me to discover specific issues related to teleoperation at the micro and nanoscopic scales. It was also an opportunity to enhance my knowledge in mechatronics and haptics.

I investigate solutions to facilitate the authoring and demonstration of haptic effect in remote situations.
We propose a series of haptic illusions and demonstrations that can be fabricated using any FDM 3D printer. Once printed, they can be fully assembled by hand.
At present, the operating room (OR) and intensive care unit (ICU) are noisy environments, exacerbated by frequent alarms. Regardless of whether the alarms are valid or false, all command attention, raise stress, and are often irrelevant to the responsibilities of individual clinicians. To cope with these problems, we are investigating the possibility of using audio only for those alarms that should be announced to the entire team, but delivering other alarm cues individually, through haptics vibrations.
Nerve damage, frequently caused by injury, can result in the loss of sensorimotor functions in certain parts of the hand. After suturing the nerve, unpleasant sensations on contact, including tingling and electric shocks are often felt. Following nerve regrowth, it is necessary to re-train the brain to interpret the signals from these nerves correctly. This project involves the design of haptic devices to help in this process of sensory reeducation, which can involve two phases, depending on the severity of the loss of sensitivity: relearning how to localize sensations, and differentiation of shapes and textures in the identification of objects.
The tactile sense can be used as a channel for general communication, especially in contexts where the visual and auditory modalities are occupied with other tasks or compromised. We propose a new method for communicating generic words through the sense of touch that relies on delivering vibration patterns, representing the phonemes composing the words, to the user’s skin through two vibrotactile transducers worn on the forearm. The novelty of this technique is that vibration patterns are created from the audio of the corresponding English phoneme, resulting in vibration patterns that resemble physical characteristics when uttering the phoneme during normal speech.
Biased perceptions of others are known to negatively influence the outcomes of social and professional interactions in many regards. This project explores how haptic effects, generated from speech, could attenuate listeners’ perceived voice-related biases.
Studies suggest that imbalances in speaking opportunities during meetings often lead to sub-optimal meeting outcomes. These imbalances can be due to a variety of reasons, including people’s perception of speakers and their voice. Indeed, speakers with higher pitched voices were shown to be perceived as having lower leadership ability. In an attempt at countering such voice-pitch related biases, this work introduces BarryWhaptics, a real-time speech-to-haptics conversion system that leverages multimodal perception to alter the listener’s perception of a speaker. The system operates by augmenting human speech with vibration, applying more intense vibrations to voices that would ordinarily be considered low in dominance. Results from a pilot study assessing the influence of the system in a decision-making task demonstrate that it can meaningfully influence how users choose to follow instructions given by one speaker over another.
As haptics have become an ingrained part of our wearable experience, particularly through phones, smartwatches and fitness trackers, significant research effort has been conducted to find new ways of using wearable haptics to convey information, especially while we are on-the-go. In this article, instead of focusing on aspects of haptic information design, such as tacton encoding methods, actuators, and technical fabrication of devices, we address the more general recurring issues and “gotchas” that arise when moving from core haptic perceptual studies and in-lab wearable experiments to real world testing of wearable vibrotactile haptic systems. We summarize key issues for practitioners to take into account when designing and carrying out in-the-wild wearable haptic user studies, as well as for user studies in a lab environment that seek to simulate real-world conditions. We include not only examples from published work and commercial sources, but also hard-won illustrative examples derived from issues and failures from our own haptic studies. By providing a broad-based, accessible overview of recurring issues, we expect that both novice and experienced haptic researchers will find suggestions that will improve their own mobile wearable haptic studies.
