Development of a quantitative evaluation tool of cognitive workload in field studies through eye-tracking (Master Thesis and further journal publications). Development of a method for the measure- ment of cognitive workload in field conditions (eye-tracking and pupillometry). Eye-tracking data has been used alongside the video feed of the field of view of the operator/observer and the data from an external luminance sensor to quan- tify the luminous flux from the point of view of the subject and estimate the effect of a generic visual stimulus on the expected pupil size. The estimated pupil size is then used as a variat- ing baseline to remove the effect of luminance on the pupil size and isolate the changes relative to mental workload. This method has been validat- ed in the lab and then trailed in field conditions thanks to the collaboration of the Royal Norwe- gian Naval Academy. My main contribution has been developing the underling computer vision pipeline and adapting an off the shelve eye track- er to be able to record data on the visual stimuli. I also had experience in instrumenting and setting up eye tracking in the lab as well as in a mobile environment (Training Vessel provided by the Norwegian Navy).

Parametric typography is a course about analysis of the relations between the typographic shapes of the letters. The analysis is then translated in mathematical models that can reproduce different part of a fonts parametrically using RoboFont and the powerful RoboFab library.
A lot of fonts.

My work group focused on the behavior of slab serifs and the various optical correction that are applied when a sans is turned in to a serif. I developed a crude but effective way of finding the intersection between a bézier curve and a line or another bézier, this permitted us to cut raw shapes with high precision.

Pallinator is a small project, a simple python script that redraws a font using a grid of shapes. It can be adapted to do many thing, including recursive typography.
