For example, different levels of stiffness can be simulated on a grasped virtual object with the same passive haptic device~\cite{achibet2017flexifingers} or
the perceived softness of tangible objects can be altered by superimposing in AR a virtual texture that deforms when pressed by the hand~\cite{punpongsanon2015softar}, or in combination with vibrotactile rendering in VR~\cite{choi2021augmenting}.

The vibrotactile sinusoidal rendering of virtual texture cited above was also combined with visual oscillations of a cursor on a screen to increase the roughness perception of the texture~\cite{ujitoko2019modulating}.
However, the visual representation was a virtual cursor seen on a screen while the haptic feedback was felt with a hand-held device.

\subsection{Improving the Interactions with Virtual Objects}
\label{vhar_interaction}
\cite{pacchierotti2015cutaneous}
Conjointly, a few studies have explored and compared the effects of visual and haptic feedback in tasks involving the manipulation of virtual objects with the hand.
\textcite{sarac2022perceived} and \textcite{palmer2022haptic} studied the effects of providing haptic feedback about contacts at the fingertips using haptic devices worn at the wrist, testing different mappings.
Results proved that moving the haptic feedback away from the point(s) of contact is possible and effective, and that its impact is more significant when the visual feedback is limited.
In pick-and-place tasks in AR involving both virtual and real objects, \textcite{maisto2017evaluation} and \textcite{meli2018combining} showed that having a haptic {rendering of the} fingertip interactions with the virtual objects led to better performance and perceived effectiveness than having only a visual rendering of the hand, similar to \figref{hands-tips}.

Moreover, employing the haptic ring of~\cite{pacchierotti2016hring} on the proximal finger phalanx led to an improved performance with respect to more standard fingertip haptic devices~\cite{chinello2020modular}.
However, the measured difference in performance could be attributed to either the device or the device position (proximal vs fingertip), or both.
