The economy and technology continues to develop, and each promoted the other. Thetechnology progress have more effect on the development of the economy. When the automobilenot just be the transport, the consumption tendency become the dual requirement of ideal andsensibility. Automobile not only represent identity and status, but also represent the taste andaesthetic, even a complete show of oneself heart. The need of personality and feeling aresatisfied by automobile, so the auto industry have to face greater challenges, the original marketdominated by producers have updated to the buyer dominated. In order to know more andsatisfied the psychological needs of consumer groups, enterprise have to do all kinds ofmarketing investigation and research continuously. With the change of the economic supply anddemand, scientific research also have a new direction. Cooperate with the theory of themarketing and management to understand the demand of the market become more perfect, itseem to be very meaningful to use technology and high-tech equipment to help understand themarket and consumer groups. This article based on perceptual technology, combined with the useof eye tracker, carried on the study of consumer psychology demand of car seats and objectiveevaluation methods of automobile seat comfort. Starting from the design touched the soul, usingscientific design method to experiment study, provides a more comprehensive and convenientdesign method and evaluation method for the enterprise.The article main content is divided into the following four aspects:1. This part of the research combined the design element regularly and acceptability by theestablishment of Likert Scale method, and then integrate the whole design idea, the aestheticform of consumer groups are primitive nature, the tendency of formal aesthetic are therhythm.According to the results of this study, from two angles to mine the design semantic resources,on the one hand, using the divergent thinking, find the key words, extract the symbol, on theother hand, to design innovation aimed at the functional structure, resource analysis of theseat based on nine screen method, and the thought experiment on STC operator, find thetechnical contradiction, then through the contradiction matrix, get the application of thenested principle, the reverse effect principle, and the principle of combination. Getting moredesign symbols and functional requirements. Combined with the research results, conductedthe idealized concept design of car seats. Finally, using eye tracker to verify the objectiveevaluation. Found that this kind of design method and design flow are effective. As a kind ofuniversal design research method, simple and easily operate and economic, can be used inthe process of product design.2. In this paper, this section combined the subjective measure of semantic differential, the levelof discomfort with local body with body pressure distribution measurement to finish theexperimental comparison, find out the objective factors that affect subjective feeling,through the study of car seat visual comfort, from the angle of outward appearance and innerfeelings, to complete the design and measurement of the automobile seat comfort. From thetest of automobile seat static comfort and questionnaire research, the appearance point ofview, and the use of semantic differential method is successful, five different aspects reflects the differences between two kinds of seats, and conformity with the actual situation, provedthat the research can continually exist in the questionnaire as the appearance evaluation. Andgave a comprehensive evaluation method of seat appearance visual comfort and tactilecomfort, which can be used for the laboratory tests and design improvements for the seatmanufacturers.3. In the actual seat vibration, the vibration frequency and transmission rates can’t be feltdirectly, just can perceptual cognize to vibration, can be described in subjective words. Theinfluence of vibration on human body also correspond to the corresponding parts`physiological reaction, and quantified the degree of the strength of the perception in the formof digital, through the questionnaire to establish a quantitative model, not only to saywhether the seat is comfortable, also can explain the concrete degree of seat vibrationcomfort, is a more detailed evaluation method. The formation of subjective and objectiveanalysis is consistent of the seat vibration comfort. Objective analysis can quantized thevibration perception which in subjective analysis, and the objective evaluation can enrich thecontent of subjective analysis, can have a good observation and quantitative for thephysiological and psychological factor which can`t reflected in the experiment, can carry onthe quantitative evaluation on the degree of comfort seat. In the development process of theseat, it is better to use two methods at the same time to verify the seat vibration comfort,through the objective experiment can help designer to control vibration of physical factors toimprove the vibration of the seat comfort, and through the analysis of subjective, it canquantify the degree of the seat vibration comfort. The combination of both can make thejudgment for the seat vibration comfort more accurate.4. Based on the perceptual technology and the cognitive psychology, formed the studyframework of this part, then from the perspective of perceptual engineering explored thepsychological cognitive process of customer’s visual comfort for the car seat, to theexploration of the psychological cognitive process, starting with eye movement trackingtechnique and form the eye tracker experiment content, through the person’s eye movementprocess to describe the person’s psychology cognitive process.On the above conclusions, using the field analysis and three axis analysis to further explorethe result of the experiment. Provided further improvement suggestions for the perfection of thedesign of the car seat.
