Development of a support system for holding chopsticks correctly

摘要

Chopsticks are tools that can easily handle food and are widely used in Asian countries. Chopsticks have functions equivalent to those of knives and forks, such as "grabbing", "cutting", "scooping" and so on. Also, properly holding of chopsticks is considered as one of manners. In order to fully use the functions of chopsticks, it is necessary to have chopsticks correctly. However, in Japan, the proportion of people who can hold chopsticks correctly is decreasing, and many adults who are over 20 years old can not possess chopsticks correctly. Therefore, in this research, we will develop an appropriate usage support system for chopsticks for adults who want to hold chopsticks correctly. In this system, the correctness of how to use chopsticks can be judged from the two situations of how to hold chopsticks and how to move them.
