While floral tributes are commonly used for the public commemo- ration of victims of disasters, war, and other accidents, flowers in vases color everyday life. In this research, these features of flowers are intertwined with the recent phenomenon of online memorials to develop a virtual floral tribute concept that includes physical rit- uals. We designed SenseVase, a smart vase to detect flowers placed in it, and a 3DCG Virtual Memorial that illustrates floral tributes given by people using SenseVases at home. This paper describes how we developed our design concept by reviewing previous lit- erature and social aspects, and presents a video illustrating the concept. To validate the current concept, we interviewed several experts knowledgeable in public commemorations, virtual and on- line communities, and the floral business. Through a discussion of our findings from the design process and interviews, we propose a new direction for how HCI technology can contribute to public commemoration in addition to personal memorialization.
