Sketch2Makizushi: Interactive Guidance System for Decorative Sushi Rolls with User Sketches

Decorative sushi rolls are produced to look like flowers or cartoon characters at their cross-sections. They are prepared by placing vinegared rice and other ingredients on a laver, which is then rolled. To create unique decorative sushi rolls, it is difficult to come up with a recipe containing descriptions regarding the number and size of the laver, the amount of vinegared rice, and the arrangement of ingredients. To address this issue, we propose using Sketch2Makizushi, an interactive guidance system that allows users to make their desired decorative sushi rolls using a sketch as an input. The proposed system can automatically calculate the recipe for the decorative sushi rolls according to the input sketch and present the cooking process. The proposed system enables the free design of decorative sushi rolls compared with conventional production approaches. We conducted an evaluation study to assess the proposed system to confirm its effectiveness and obtain information on user experience.
