TOCHI paper from K. Fennedy in collaboration with S. Perrault on soft keyboard hotkeys is now available.

2021 Aug. 17:

Two research papers accepted. First is a follow up from K. Fennedy in collaboration with S. Perrault on soft keyboard hotkeys that was accepted to TOCHI. Second is a work from R. Hanada and D. Masson, in collaboration with G. Casiez and M. Nancel on hardware-independent pointing transfer functions that was accepted to UIST 2021. Great job everyone!

I am a research scientist (Chargé de Recherche 1ère classe) at Inria, in the Loki group. Prior to that, I was a post-doctoral researcher at the University College London and at the University of Canterbury (New-Zealand). I did my Ph.D. at Télécom ParisTech, and passed my Master Degree at UPMC in Artificial Intelligence with a speciality in HCI. I am also an adjunct assistant professor at the University of Waterloo, Canada (2021-2024).

My research interests are in the areas of human-computer interaction (HCI), with additional focus on designing interactive systems and interaction techniques that can be easily discovered and learned by novice users, while still yielding high performance to more practiced users. More generally, I am highly interested in how interaction can be communicated to the user to foster its discovery. If you are curious about my research, giving a look at the selected publications below should provide a decent overview.

I currently am the Principal Investigator of the ANR JCJC Discovery project (2020-2023) that investigates the design of Graphical User Interfaces that would better support the discovery of their interactive principles.
