The virtual forms present dynamically generated visual images containing information that influences a users behavior and thinking. In a typical way, adding a display to show visual expressions or projecting some information on an artifact offers computational visual forms on the existing daily artifacts. Using virtual forms is a very promising way to enhance artifacts surrounding us, and to make our daily life and business richer and more enjoyable. We believe that incorporating fictional stories into virtual forms offers a new possibility for enriching user experiences. In particular, integrating fictional stories into our daily activities through transmedia storytelling is a promising approach. Transmedia storytelling enables virtual forms to be employed everywhere to immersively integrate fictional stories into our daily activities. If we can design attractive virtual forms in a structured way, it will become easy to enrich user experiences. Currently, the design framework for virtual forms is not well defined. The framework needs to take into account the semiotic aspect of a virtual form. One key factor, in particular, is how strongly we believe in the reality of a fictional story within the virtual form. In this paper, we show the extracted insights discussed in the workshops and present some design implications for designing virtual forms that integrate fictional stories into our daily activities.
