 Participants rated the roughness of the paper (without any texture augmentation) before the experiment on a 7-point Likert scale (1~=~Extremely smooth, 7~=~Extremely rough) as quite smooth (\mean{2.5}, \sd{1.3}).

 An \OST-\AR headset was chosen over a \VST-\AR headset because the former only adds virtual content to the \RE, while the latter streams a real-time video capture of the \RE, and one of our objectives was to directly compare a \VE replicating a real one, not to a video feed that introduces many other visual limitations (\secref[related_work]{ar_displays}).

 The \VE carefully reproduced the \RE, including the geometry of the box, textures, lighting, and shadows (\figref{renderings}, \level{Virtual}).
 The virtual hand model was a gender-neutral human right hand with realistic skin texture, similar to that used by \textcite{schwind2017these}.
 Its size was adjusted to match the real hand of the participants before the experiment.
