Face-Based Glyphs Revisited

In Short Paper Proceedings of EuroVis 2022, pp. 19–23, 2022.

Abstract

While face-based glyphs have known advantages for certain visualization tasks, they suffer from mixing two rather different visual properties of faces: individual traits and emotion expressions. This paper proposes a set of actions on stylized face glyphs that are compatible with psychological evidence embodied in the facial action coding system. It shows how this set can be employed for distinguishing emotion expressions from other facial expressions, and derives an emotion-based glyph space to exploit the pre-attentive processing of emotion expressions. Finally, we report the results of an empirical user study comparing Chernoff-like glyphs with our emotion glyphs in a typical visualization task.
