This paper presents the scrapbook mobile app for families, resulting from a user-centered research through design project. This app is intended to be used by family members to embed a variety of content related to family events on its interface which combines features of a calendar and a photo album. The app takes as its premise the generative potential when parents and children plan, share, and recollect family events together. This paper also presents the design process of the app and proposes the main design concept of complementing family communication in a time-series relation among the past, current, and the future. Reflecting on the overall design process, we discuss the app and our design activities, particularly, in terms of the relevance of our concept, impacts on family communication, and the relation to other design examples. We suggest that this work has implications not only for the design of mobile apps such as that in this case study, but also for the design of all interventions aimed at supporting family communication.
