POOP UP is a service design system with the stoma patient in mind. While it helps to address the stoma leakage that is a major concern for people with stoma, it also attempts to improve the psychological problems of people with stoma. Converting the poo they least want to see into a link to reconnect with society. It also allows the general public to learn more about this group of people. POOP UP, which stands for "pop up", means to appear out of nowhere. Although this annoying pocket appears unexpectedly, we don't want patients to see it as a burden, but rather as a pocket for Doraemon, from which they can make up many valuable things, and this is the idea I always try to convey to the patients.
