Abstract
Products with interactive interfaces can be seen everywhere, and product interface design aesthetics is a topic that has begun to receive wide attention. Consumers’ perceptions of product interfaces come from their own emotions, and emotion plays a significant role in product interface design aesthetics. In other words, it must meet the users’ emotional and aesthetic requirements. Therefore, we need to better understand the aesthetic design criteria and how they stimulate specific emotional responses. This study takes the dial interface of smartwatches as its experimental sample and explores how the interaction effects of the screen shape (square and round) and the symmetry type and the complexity type of the interface design influence the users’ emotional arousal and valence. In addition, it analyzes the effects of the symmetry type, the complexity type, and the screen shape on the users’ arousal and valence. The results show that the attributes of interface design aesthetics (symmetry-asymmetry, complexity-simplicity, and square-round) affect the users’ emotional responses. Moreover, the interface shape is one of the important factors in the emotional response to an interface design. This paper, based on previous research, provides vital theoretical support for the relevant literature on interface design aesthetics and the users’ emotional state. In addition, it may provide a reference for designers and developers who wish to develop and implement emotional user interfaces that are designed to more effectively appeal to their emotions.
Highlights
With the continued development of science and technology, an increasing number of products are being designed with touch interfaces
Three-way independent-sample ANOVAs were used to analyze the effects of the symmetry type, the complexity type, and the screen interface shape on arousal, as related to the smartwatch interface design
The results showed that the symmetry type had a significant effect on arousal
Summary
With the continued development of science and technology, an increasing number of products are being designed with touch interfaces. Human–Computer Interaction (HCI), or interactive product design, user interface design aesthetics has become the main topic of concern. Ngo and Byrne defined the aesthetic criteria of interface design as an objective, automatable metric of screen design, which can help designers to create attractive screens [5]. They have developed the following 14 objective measures of screen aesthetics: balance, symmetry, equilibrium, unity, sequence, density, proportions, cohesion, simplicity, regularity, economy, homogeneity, rhythm, Symmetry 2020, 12, 1403; doi:10.3390/sym12091403 www.mdpi.com/journal/symmetry
