1 Introduction

Product design evaluation is the complex system including two aspects, “ration” and “emotion”, and multiple factors. With the further pursuit of better life of human society and the continuous enhancement of realization of science and technology, the traditional product design philosophy led by “functional practice” or “technology” has converted into the modern product design philosophy led by “user experience” or “emotion”. Product design evaluation has become the new concern of the current product design research, and the scientific evaluation of subjective “emotional” factors in product design evaluation is the difficulty. It is the urgent practical needs to establish a scientific and high-efficient product design evaluation system as soon as possible, so as to improve product design innovation ability and scientific level, improve the success rate of enterprise product development and shorten the development cycle, etc.

2 Analysis of Research Status

Many scholars have carried out extensive researches on product design evaluation and have achieved encouraging results. A. Mousavi et al. [1] studied the complex problem of user preferences in the practice of product design and put forward a “customer optimization path and assessment model”, i.e. CORE; X. Zeng et al. [2] proposed a fuzzy multiple criteria evaluation method of “fashionable design-oriented industrial products”; Chulwoo Kim et al. [3] proposed an efficient evaluation method of user impression by using the virtual prototype to analyze products; A. Rashid et al. [4] studied an intelligent design system evaluating the product aesthetics; Carmen Llinares et al. [5] studied to use Kano model to analyze the impact of different subjective attributes on consumer purchasing decisions based on Kansei engineering theory; Mark Evans et al. [6] studied the tactile feedback model evaluation in the practice of industrial design; Hyungjun Park et al. [7] studied the design evaluation of information devices based on tangible interactive Augmented Reality Technology; Francisco Rebelo et al. [8] studied the use of virtual reality to evaluate the user experience, etc.

For emphasizing the emotional experience interaction issues of users under the new concept of and current product design, various scholars have studied the quantitative evaluation of subjective factors on “emotion” based on Kansei engineering theory [5, 6], and the use of virtual reality technology to allow users to achieve “immersive emotional interactive experience” and realize intuitive and high-efficient evaluation [3, 7, 8], etc. However, the products will show great differences due to different individual types in the product design evaluation; meanwhile, product design evaluation is accompanied by the entire cycle of products from concept, design and verification to production. Evaluation indicator and assessment methods are different at all stages, so it brings about great inconvenience and difficulties for people conducting product design evaluation. There has not been the current research involved in the issue how to make every product get the most scientific and rational design evaluation at maximum efficiency. In addition, the data acquisition picture samples in Kansei engineering will affect the quality of samples because of not strong “sense of reality”, and the data collecting actual samples will cause a lot of waste of manpower and material resources; if the visual experience component in the virtual reality is not processed scientifically, it will be difficult to ensure the scientificity of product design evaluation.

Therefore, scientifically extract the common factors from products, use the high-efficient technologies, scientific theories of the quantitative evaluation in Kansei engineering and the intuitive interactive evaluation in virtual reality, to effectively integrate product design evaluation method and model, systematically build scientific and high-efficient product design universality evaluation standard system, and make a useful exploration on the researches on complex product design evaluation system.

5 Conclusions and Prospect

The author in this paper constructs the product design universality evaluation standard system based on Kansei engineering theory and virtual reality technology, which will effectively solve the realistic problem of current product design evaluation to the maximum: people are often at a loss during conducting the product design evaluation. On the one hand, people do not know what ways or means they can achieve the effect of the scientific evaluation; On the other hand, are there methods or models, etc. which can effectively solve design evaluation problem of the product among nearly one hundred product design evaluation methods or models. There are great differences in evaluation indicators of nearly one hundred product design evaluation methods or models, which are likely to cause thinking confusion of evaluation users and difficulty in evaluation work. Establish a set of generally applicable evaluation indicator standards and the corresponding evaluation solutions, and condense and unify the evaluation indicators, so as to make the product design evaluation become more standardized and objective, which provides theoretical support for the government establishing the scientific and standardized product design evaluation standards or specifications from the national level.

The product design universality evaluation criteria system established based on the “scientificity” of Kansei engineering and “technical advancement” of virtual reality provides scientific basis and guidance for enterprise conducting product independent innovation design, which is of important strategic significance and practical significance to enhance the product design and innovation ability, scientific level and quantitative evaluation ability in our country, improve corporate product development efficiency and reduce corporate product development risks, etc. The project research results will provide theoretical support, quantitative evaluation method and technological means for product design theory research.
