To assist busy people such as working persons, students, and nurturing families to have economical and healthy lives with homemade cooking, we have proposed a Web-based HOmemade Cooking Assistance System (HOCAS). Previously, we implemented the menu planning function and the cooking-step scheduling function at the server using JSP/Servlet, so that a user can plan a menu for the whole week and make a cooking-step schedule to efficiently cook multiple dishes at the same time. Unfortunately, a user needs to refer the next cooking-step on a paper during cooking process, which is actually not easy at critical timing in a kitchen, because the schedule is output as a PDF file. In this paper, we propose a cooking guidance function on an Android tablet as a Java application to navigate cooking-steps through touch panel operations. We confirmed the effectiveness by experimentally cooking four dishes using this function.
