Proposal of Kansei Support System to Choose Menu Based on a Survey at Kaiten-Sushi Restaurant

In recent years, the development of food culture and transportation has increased our chances of meeting unknown dishes. However, it is not easy to choose these new dishes without enough information about them. Although there is much research on menu choice and new dining experiences, but only some research is based on the behavior analysis of menu choice at a restaurant. Moreover, there have yet to be approached to propose a menu choice system based on this analysis. This study aims to survey users’ behavior when choosing a menu at Kaiten-Sushi restaurants and clarify users’ dissatisfaction and factors to interrupt the choice of new dishes using the service blueprint method and the customer journey map method. Moreover, the proposal of a new support system to choose a menu based on the survey result is the final purpose of this research. Therefore, we visited three Kaiten-sushi restaurants in Hakodate and investigated dining experiences there. As a result, we could extract the following three points; 1) There is an active type of menu choice and a passive one at Kaiten-sushi restaurants. 2) There are different types of expressions of allergy information, easy to understand or not. 3) Different languages in the menu information depending on the restaurant. Based on these results, we proposed a new Kansei support system. The Kansei support system has two main features; 1) Allergy information for specific products is expressed on each dish information page of the system. 2) The new expression of dish information which users can be interested to learn new information about the dish.
