== Warm-up ==

* managed to pretty quickly figure out the amount of pressure that was needed to draw

== Task: Constrained drawing, Little Precision Required ==

* completed the task without any problems
* said that he was mostly looking at the tablet for precision, and only glancing up at the screen

== Task: Unconstrained Drawing, Little Precision Required ==

=== Fixed Mode ===
* tried using the grab button with the stylus to move around. At first did not realize what was happening, and said that he wasn't sure what direction he should move the stylus in to achieve what he wanted, but it became clear pretty quickly

=== Movable Mode ===
* said that it made more sense to him, and liked the fact that he could see the entire drawing

=== Dynamic Mode ===
* ran into a problem a problem where scribbles were being made around the cursor, and the mapping rectangle kept moving up and up. This was something I had encountered a few times before, and assumed it to be a bug in the software. However, we eventually realized that it was being caused by not applying enough pressure. He was effectively drawing a dotted line, but because of the mapping mode, all the dots were appearing in the same place; and because he was moving across the tablet, the mapping rectangle was constantly being remapped in the opposite direction 

== Task: Constrained Drawing Requiring Precision ==

=== Dynamic Mode ===

* was able to complete the task easily

=== Alt-Hover Mode ===

* in this mode, he said his first inclination was to pick the stylus up when he released Alt, as if using Alt engaged dynamic mode temporarily.
