 \subsection{Altering the Perceptions}
 \label{vhar_perception}
 
+% In 2010, they were research interest on building haptics (dynamic tactile feedback) for touch-based systems. [@Bau2010Teslatouch] created a touch-based surface rendering textures using electrovibration and friction feedback between the surface and the user's finger.
+% They extended this prototype to in [@Bau2012REVEL] to alter the texture of touched real objects using reverse electrovibration. They call this kind of haptic devices that can alter the touch perception of any object without any setup as *intrinsic haptic displays*. They said [@Azuma1997Survey] as envisioned this kind of AR experience.
