The research talks about cross-cultural product design which combines cultural tradition and user's behavior and perception. It provides an example of a tea product design, demonstrating the process of how to include Chinese's tea culture and perception about tea drinking from people who live in North America in a cross-cultural product. To understand what are Chinese cultural elements and the users' perceptions about tea, this study first investigated current Chinese cultural products and conducted 100 interviews about drinking tea. This study suggested a method of designing a cross-cultural product, which consists of two main parts. One is to investigate the traditional design elements of one's culture and the other is to learn the users' perceptions.
