However, designing believable characters remains a challenging task. Artists rely on stylization to increase appeal or expressivity, exaggerating or softening specific features. In this paper we analyze two of the most influential factors that define how a character looks: shape and material. With the help of artists, we design a set of carefully crafted stimuli consisting of different stylization levels for both parameters, and analyze how different combinations affect the perceived realism, appeal, eeriness, and familiarity of the characters. Moreover, we additionally investigate how this affects the perceived intensity of different facial expressions (sadness, anger, happiness, and surprise). Our experiments reveal that shape is the dominant factor when rating realism and expression intensity, while material is the key component for appeal. Furthermore our results show that realism alone is a bad predictor for appeal, eeriness, or attractiveness. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.218 2015 COMPUTER SCIENCE, SOFTWARE ENGINEERING 1 / 106 = 0.009 2015 Q1 T1 2.382 2015 Computer Graphics and Computer-Aided Design 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-3532-6855 Aliaga, Carlos Universidad de Zaragoza (orcid)0000-0001-9000-0466 Jarabo, Adrian Universidad de Zaragoza Zibrek, Katja (orcid)0000-0002-7503-7022 Gutierrez, Diego Universidad de Zaragoza McDonnell, Rachel Botsch, Mario 5007 570 Universidad de Zaragoza Dpto.
