My current research focus is on perceptibility and discriminability of shapes and glyphs such as those commonly used in visualization displays. So far, my studies have explored the variation between shapes bounding a region (closed shapes) and shapes comprised of line segments (open shapes). We have used a Flanker paradigm and a Same-Different task to show a significant effect of the aforementioned dimensions on participants' ability to identify targets or discriminate between shapes. I am in the process of writing up these results, connecting them to the literature in visual perception, and motivating their importance to the field of visualization.
