With the advent of the service experience, the role of service design in satisfying customers' preferences and focusing on the value of consumers' personal experiences is becoming important. This study sought to derive the prospect and direction of contents of service design output as a result of the paper through the consideration of the content value and role of service design output, literature study, and case analysis. If you look at this, it looks like this: First, as we enter the age of content production that sells experience to customers, we need to be able to grasp the role of design content that provides intangible experience rather than tangible goods. Second, the development of service design content requires a process that resolves the cognitive experience of the user's experience and is persuasive, and also provides the results that can be presented visually can be an important solution. Third, it is expected that service contents will be required to consider hyper-connectivity using ICT in the fourth industrial era and identify the needs of consumers and sublimate them into a more valuable experience. Through the results of this study, we were able to present a plan for developing content that can satisfy customer needs in service design and, in addition, research materials that can raise the quality of service contents that are key in service development.
