Abstract
After completing the market positioning of products, catering for the functional and emotional needs of consumers is the key to achieve the success of product design. In the present study, the psychological theory is employed to screen the subjects and quantitatively evaluate the alternative design schemes to ensure the optimal design scheme. Then, an evaluation method of product appearance design based on eye tracking and aesthetic perception measurement is obtained. With the design of campus street lamp as an example, this paper evaluates the appearance design of products using emotional measurement and eye tracking technology. IAPS is used to screen out the participants who can represent the emotions and aesthetic experience of the public. Subsequently, the index system of aesthetic evaluation is established according to aesthetic theory, and the transformation relationship between aesthetic evaluation index and physiological eye movement index is determined. Finally, the eye tracking technology is used to evaluate the aesthetic feeling of each alternative, and the best design schemes are obtained. This study aims to explore a simple, practical, and low-cost product design evaluation method. As a hotspot in the research field of product design methodology, emotional design has broad prospects for application. Moreover, this paper also proposes a new direction for the development of emotional design research, which is based on quantitative analysis with the supplement of qualitative analysis.
Highlights
A vital purpose of product design is to satisfy the needs of consumers
With the development of science and technology in recent years, a futurist John Naisbitt once said: the more technology we introduce into our lives, the more we seek a high touch balance, namely, a human ballast [1]. erefore, it is significant for product designers to identify the specific needs of customers, connect it with the product attributes, obtain an accurate product design scheme, and have a valid evaluation method
Evaluation Results. rough eye movement experiments and analysis of the results, we get the aesthetic value of 20 design schemes
Summary
A vital purpose of product design is to satisfy the needs of consumers. In the context of economic growth, the enterprise-dominant market has changed into the customerdominated market. The development of eye tracking techniques makes the method of measuring the aesthetic indexes of the product by observing visual information, such as eye movements and pupil changes, gradually accepted. Factor analysis can be used to extract statistical results of the SD method, reduce the dimension of the variables, and make full use of the information obtained by the survey to simplify the evaluation scale of the product; it is very suitable for the reference and evaluation of the overall design. Huang et al conducted a study on the use of IAPS in China and found that it was highly correlated with test results in other countries, but Chinese subjects had significant differences in validity and arousal from standard scores, and some pictures even had completely different emotional performances [19,20,21]. The eye tracking technology was utilized to evaluate the aesthetic perception of the alternatives, and the final design scheme was attained
