Emotional factors of bra that effect satisfaction and attractiveness

PurposeThe purpose of this paper is to analyze the relationship between affect space and bra design factors based on the observer's vision judgment.Design/methodology/approachFirst, using two dimensions of attractiveness and satisfaction to define the bra emotion space based on literature. Then, the mapping relation between bra design factors and emotional space is analyzed in visual perception. Finally, the model of bra emotion recognition based on design factors is established using the neural network BRP.FindingsUsers' emotions stimulated by bras can be automatically recognized based on their visual design factors. (1) attractiveness and satisfaction which are used to define bra emotions space show a linear correlation between each other in the human visual domain. (2) The design factors that cause attractiveness can also cause satisfaction. However, the factors that stimulate satisfaction do not necessarily attract users' interest, such as the ratio, location of embellishments, hollowed, core decoration and contour lines.Practical implicationsThe analysis of bra emotion space may help designers to understand the relationship between bra visual appearance and emotion, and ask them to pay attention to empathic design factors. With the provided results, designers can also carry out and evaluate emotional bra design with high attractiveness and satisfaction.Originality/valueThis paper discusses the emotional attributes of bra visual design factors based on bra emotion space and explores the methods of bra emotion design.
