Design and Implementation of Meal Information Collection System Using IoT Wireless Tags

In recent years, people with lifestyle-related diseases are increasing, because of lack of exercise, overeating, stress and smoking. With this situation, applications of Personal Computer (PC) or smart phone which support healthy life are widespread. Turning to the system dealing with meal information, there are two type systems. One is that meal records are inputted by hand and managed as meal logs. Another one is that a meal image is shot by a smart phone, and meal contents are recorded by image recognition. However, these systems need a lot of time for inputting of meal contents or shooting of meal images. Therefore, it is difficult to continue use. Moreover, the second system has a problem for accuracy of image recognition. In this paper, to solve these problems, we propose a meal information collection system which uses IoT wireless tags. An IoT wireless tag is corresponded to a meal and the system can automatically get meal information such as meal contents, meal sequence, meal time and so on. We implemented the meal information collection system which aims automatic collection and getting of various information which do not get at other systems. From the evaluation results of collection accuracy and comparison with conventional systems, we verified effectiveness of the proposed system.
