Within HCI, CSCW, and other related disciplines, participatory design has been proven to be an effective way of developing technological solutions where the end- users are involved throughout the design process. This study aims to find out how and to what extent can the participatory design approach be implemented and investigated involving the end-user perspective to enhance cultural heritage experience in a case study of the Majapahit sites. The process started with an initial understanding of the users and the user’s need via online pre-study involving 53 respondents. The insights gathered envision the possible attributes of design solutions, the visiting experience in Majapahit sites, and the participants' relevant background. Three co-designing sessions with 35 participants were conducted, some needs and qualities were discussed based on the design process and the results of 11 design ideas from the design workshops. Later, to understand the usefulness and novelty of the identified design alternatives conducted from the workshops, further analysis of the design creativity was conducted with two experienced designers. The findings of the thesis involve five design areas in cultural heritage experience: improving the basic facility, support of learning about cultural heritage, assisting the visitor to explore the cultural heritage, social experience of cultural heritage, and support of entertainment and challenge in the cultural heritage experience. Hence, this study enables HCI researchers to do further study in regard to Majapahit sites or in the domain of cultural heritage in general.
