TEXTURAS BIOINSPIRADAS: Análise da Experiência Perceptiva e Afetiva do usuário

Abstract

This study proposes an investigation into the creation of bio-inspired textures, focusing on affective analyses and their influence on cognitive processes. The methodology, based on an experimental procedure, includes a qualitativequantitative approach based on the Design Science Research method. Four models were produced, divided into two groups (G1 and G2), and three evaluation protocols were subsequently applied with users in a public space. The sample consisted of 30 participants, divided into 15 participants for each group, who interacted with the samples. The collected data were analyzed based on descriptive and inferential statistics. The results indicate that surfaces with a higher contrast difference between figure and background with high relief were perceived as more organized, beautiful, attractive, and easy to interpret, resulting in lower mental workload and lower frustration rates. On the other hand, samples with low relief and a lower contrast difference required more observation time, higher cognitive effort, and generated more critical responses regarding legibility and visual complexity. Qualitative analysis revealed that factors such as background color, sharpness of contours, and symmetry were decisive in the participants' evaluation. The responses also highlighted the relevance of tactile perception in the construction of aesthetic and functional judgments of surfaces. The results demonstrate that cognitive ergonomics also works as a fundamental factor in the development of bio-inspired surfaces by promoting a more affective and comfortable interaction between user and object. Thus, the research contributes to the research design by pointing to ways for more interactive and affective projects in the context of product design.
