Abstract
The current research on human-machine interaction interface layout focused on ergonomic analysis, while the research on aesthetics and aesthetic degree calculation of interface layout was insufficient. In order to objectively evaluate the aesthetic degree of interface layout, this paper put forward an aesthetic degree evaluation method of interface design based on Kansei engineering. Firstly, the perceptual image structure of interface aesthetic degree was analyzed from the perspective of aesthetic cognition. Six aesthetic image factors affecting interface aesthetic degree, including proportion, conciseness, order, rhythm, density, and equilibrium, were extracted by factor analysis method, and the variance contribution rate of each factor was taken as the weight. Secondly, according to the six aesthetic degree indexes, the calculation system of interface aesthetic degree was constructed, and the aesthetic degree value of aesthetic image factor was calculated by the corresponding aesthetic degree evaluation mathematical formula. Then, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method was used to analyze the order of aesthetic degree superiority of design schemes, and the comprehensive aesthetic degree evaluation was carried out. Finally, the aesthetic degree evaluation of human-machine interaction interface layout of the driller's console of an AC variable frequency drilling rig was taken as an example to verify that this method was helpful for designers to optimize the design scheme. The experimental results showed that the proposed method was feasible and effective compared with the method of paired comparison commonly used in psychophysics.
Highlights
Human-machine interaction interface is a medium for people and machines to transfer information to each other
In order to quantify the visual aesthetics of interface layout accurately, as shown in Figure 2, the layout interface is abstracted as rectangle, and the layout objects are abstracted as rectangle or circle. e layout interface was divided into four areas: top left, top right, bottom left, and bottom right
In view of the fact that aesthetic cognition was a complex and subjective psychological activity, the aesthetic degree of the four layout schemes was evaluated subjectively by the method of paired comparison commonly used in psychophysics in this paper. e four schemes in Figure 3 were successively numbered as A, B, C, and D
Summary
Human-machine interaction interface is a medium for people and machines to transfer information to each other. Yun et al [19] took software interface layout and color features as research objects and established a relationship model between features and software aesthetics by genetic algorithm and radial basis function (RBF) network These studies were built on the basis of few samples of specific typical cases, and it remained to be seen whether their prediction accuracy and research conclusions could be extended to other interface designs. Erefore, on the basis of previous studies, this paper attempted to use Kansei engineering’s quantitative analysis method of perceptual experience [26, 27], extract aesthetic image factors of human-machine interaction interface from the perspective of aesthetic cognition, construct the perceptual image structure of aesthetic degree, and establish the corresponding mathematical formula of aesthetic evaluation to calculate the aesthetic value of aesthetic image factors. An example is given to illustrate the implementation steps of the evaluation method of interface aesthetic degree, and the effectiveness of the proposed method is verified
