Unity enhances product aesthetics and emotion

Abstract

Although the aesthetic properties of a product are likely associated with users' emotional responses, empirical evidence does not explain how the aesthetic properties of a product evoke an emotional response. This study presents the hypothesis that users' emotions are evoked when they observe an aesthetically pleasing product with unity. The results implied that a product form with more unity had a greater likelihood of affecting users' positive emotions compared with those with less unity, and that the unity aesthetic may act as a mediator in evoking emotion. In addition, the results confirmed that products composed of curvier elements tended to evoke a stronger pleasure response compared with those defined by straight lines. A systematic approach, namely the decision tree method, acts as a unity design guideline for the enhancement of product aesthetics, which may evoke users’ pleasure responses further. Relevance to industryOur findings imply that a product form with more unity had a greater likelihood of affecting users’ positive emotions compared with those with less unity. In addition, a systematic approach, namely the decision tree method, acts as a unity design guideline for the enhancement of product aesthetics, which may apply for designing products with pleasures.
