For example, a \v-\AE that uses a tangible (touchable) object as a proxy to manipulate virtual content is considered a \h-\RE (\eg \figref{kahl2023using}; bottom middle cell in \figref{visuo-haptic-rv-continuum3}), whereas a device that provides synthetic haptic feedback when touching a \VO is considered a \h-\VE (\eg \figref{meli2018combining}; top middle cell in \figref{visuo-haptic-rv-continuum3}).

Haptic \AR is then the combination of real and virtual haptic stimuli~\cite{bhatia2024augmenting} (middle row in \figref{visuo-haptic-rv-continuum3}).

It is possible instead to place the haptic actuator close to the point of contact with the \RE, as described above to implement \h-\AR, \eg providing haptic feedback on another phalanx~\cite{asano2015vibrotactile,salazar2020altering} or the wrist~\cite{sarac2022perceived} for rendering fingertip contacts with virtual content.

\section{Approach and Contributions}
\label{contributions}
The aim of this thesis is to understand how immersive visual and \WH feedback compare and complement each other in the context of direct hand perception and manipulation with augmented objects.

As described in the Research Challenges section above, providing a convincing, consistent and effective \vh-\AE to a user is complex and raises many issues.
