Sketch2Bento: Sketch-based Arrangement Guidance for Lunch Boxes

In recent years, sharing the images of the meals has been popular on social media as an artwork. In terms of the food culture in Japan, the lunch box is especially prevalent because of the lovely looking, such as character-bento. However, it is challenging and difficult to arrange a lunch box for common users without experiences and delicate skills. In this work, we propose Sketch2Bento, a sketch-based arrangement guidance system of food ingredients using spatial augmented reality technology. The proposed sketch interface allows users to design the blueprint of a desired lunch box. We then utilize the projection mapping to guide users with the projected arrangement hints in the boxes accordingly. Finally, we conduct a user study to verify the system usage and user experiences.
