In a user study not in \AR, but directly touching images on a tablet, Fingeret was found to be more realistic (4/7) than a \LRA at \qty{100}{\Hz} on the nail (3/7) for rendering buttons and a patterned texture (\secref{texture_rendering}), but not different from vibrations for rendering high-frequency textures (3.5/7 for both).
However, as with \textcite{teng2021touch}, finger speed was not taken into account when rendering vibrations, which may have been detrimental to texture perception, as described in \secref{texture_rendering}.
Finally, \textcite{preechayasomboon2021haplets} (\figref{preechayasomboon2021haplets}) and \textcite{sabnis2023haptic} designed Haplets and Haptic Servo, respectively: These are very compact and lightweight vibrotactile \LRA devices designed to provide both integrated finger motion sensing and very low latency haptic feedback (\qty{<5}{ms}).

However, no proper user study has been conducted to evaluate these devices in \AR.
