\label{real_virtual_gap}
In \AR and \VR, the state of the system is displayed to the user as a \ThreeD spatial \VE.
In an immersive and portable \AR system, this \VE is experienced at a 1:1 scale and as an integral part of the \RE.

This suggests the feasibility of using simplified tangibles in \AR whose spatial properties (\secref{object_properties}) abstract those of the \VOs.
Similarly, in \secref{tactile_rendering} we described how a material property (\secref{object_properties}) of a touched tangible can be modified using wearable haptic devices \cite{detinguy2018enhancing,salazar2020altering}: It could be used to render coherent visuo-haptic material perceptions directly touched with the hand in \AR.
