The phase matching avoids sudden changes in the actuator movement thus affecting the texture perception in an uncontrolled way (\figref{phase_adjustment}) and, contrary to previous work \cite{asano2015vibrotactile,ujitoko2019modulating}, it enables a free exploration of the texture by the user with no constraints on the finger speed.

A square wave is chosen to get a rendering closer to a real grating texture with the sensation of crossing edges \cite{ujitoko2019modulating}, and because the roughness perception of sine wave textures has been shown not to reproduce the roughness perception of real grating textures \cite{unger2011roughness}.

% Les dispositifs haptiques portables procurent des sensations tactiles tout en étant compacts.
|
||||
% Mais ils ont été peu utilisés en réalité augmentée (RA), où le contenu virtuel est intégré à la perception du monde réel.
|
||||
% Cette thèse explore leur potentiel pour améliorer les interactions de la main avec des objets virtuels en RA.
|
||||
% Nous étudions d'abord l'impact du rendu visuel sur la perception des textures vibrotactiles virtuelles qui augmentent des surfaces réelles touchées directement par le doigt.
|
||||
% Nous étudions ensuite comment des retours sensoriels visuo-haptiques augmentant la main améliorent les performances et l’expérience utilisateur lors de la manipulation d'objets virtuels en RA.

Dans ce manuscrit de thèse, nous montrons comment la \emph{réalité augmentée (RA)}, qui intègre un contenu visuel virtuel dans la perception du monde réel, et l'\emph{haptique portable}, qui fournit des sensations tactiles sur la peau, peuvent améliorer les interactions de la main avec des objets virtuels et augmentés.
