  The act of selection plays a leading role in the design process and in the
definition of personal style. This work introduces visual selection catalogs
into parametric design environments. A two-fold contribution is presented: (i)
guidelines for construction of a minimal-bias visual selection catalog from a
parametric space, and (ii) Inbetween, a catalog for a parametric typeface that
adheres to the guidelines, allows for font selection from a continuous design
space, and enables the investigation of personal style. A user study conducted
among graphic designers, revealed self-coherent characteristics in selection
patterns, and a high correlation in selection patterns within tasks. These
findings suggest that such patterns reflect personal user styles, formalizing
the style selection process as traversals of decision trees. Together, our
guidelines and catalog aid in making visual selection a key building block in
the digital creation process and validate selection processes as a measure of
personal style.
