The appeal of consumers choosing their products has changed from being functionally practical to sensational, and sensation has already become the main motivation for consumers to choose their products. Also, lifestyle ethnic groups are the most favorable analyzed subjects of marketing currently, so making good use of ethnic lifestyle group analysis to penetrate the consumer market in Taiwan will be helpful for operators of different industries to realize the characteristics of potential consumers. In the future, all kinds of lifestyle ethnic groups will be targeted to conduct deeper observation, investigation, and research of specific themed products or services. This research will hold 2 expert group seminars respectively though literature review, expert group seminars, and Method of Semantic Differential, and 131 total questionnaires will be distributed in two batches to implement a three-phase experimental survey and conduct research on three lifestyle ethnic groups and their corresponding Semantic Differential. The research results obtained the 31 most commonly used Semantic Differentials on design, and the 3 most often encountered lifestyle ethnic groups on design, which are LOHAS, the technology group, and texture group. Meanwhile, the respective image expect vocabulary of the three lifestyle ethnic groups will also be obtained, for example, the images expect vocabulary of LOHAS is practical, simple, and organic. The images expect vocabulary of the technology group is versatile, streamlined, innovative, and technological. The images expect vocabulary of the texture group is fashionable, popular, luxurious, and abstract. Through the results of the research, we can also obtain that (1) different lifestyle ethnic groups actually have different corresponding Semantic Differentials, and (2) not all of the commonly used Semantic Differentials on design are suitable for different lifestyle ethnic consumption groups, so the extraction of Semantic Differentials should actually be put in more detailed divisions. Moreover, (3) the Semantic Differentials decided by different designers on different lifestyle ethnic groups might lead to the distortion of the extraction of designing elements because the deciding process is too rough. Also, (4) the research of the relevance among different lifestyle ethnic groups, Semantic Differentials, and images can be conducted subsequently, and the e-platform of an image billboard can be constructed to be a tool able to support and operate during design.
