“…In humans, the visual system is the preferred way to decode the environment, to orient oneself, to detect dangers, to identify edible foods, but also to appreciate the aesthetics of a product, admire the beauty of a landscape or a person ( Barrett and Bar, 2009 ; Tonder and Spehar, 2013 ). Visual functions are also known to create the aesthetic experience which contributes significantly to the creation of the hedonic judgments involved in the appreciation of aesthetic and perceived properties of objects ( Lajoie and Delorme, 2003 ; Mottier, 2020 ). In this framework, part of the material experience depends on the texture as was described by Klatzky et al (1989) , but also by the unconscious response produced during the visual examination of textures ( Landy and Bergen, 1991 ).…”

IntroductionDesigners know that part of the appreciation of a product comes from the properties of its materials. These materials define the object’s appearance and produce emotional reactions that can influence the act of purchase. Although known and observed as important, the affective level of a material remains difficult to assess. While many studies have been conducted regarding material colors, here we focus on two material properties that drive how light is reflected by the object: its metalness and smoothness. In this context, this work aims to study the influence of these properties on the induced emotional response.MethodWe conducted a perceptual user study in virtual reality, allowing participants to visualize and manipulate a neutral object – a mug. We generated 16 material effects by varying it metalness and smoothness characteristics. The emotional reactions produced by the 16 mugs were evaluated on a panel of 29 people using James Russel’s circumplex model, for an emotional measurement through two dimensions: arousal (from low to high) and valence (from negative to positive). This scale, used here through VR users’ declarative statements allowed us to order their emotional preferences between all the virtual mugs.ResultStatistical results show significant positive effects of both metalness and smoothness on arousal and valence. Using image processing features, we show that this positive effect is linked to the increasing strength (i.e., sharpness and contrast) of the specular reflections induced by these material properties.DiscussionThe present work is the first to establish this strong relationship between specular reflections induced by material properties and aroused emotions.
