幫助使用者健康烹飪的卡路里感測智慧型廚房

Abstract

As a daily activity, home cooking is an act of care for family members. Most family cooks are willing to learn healthy cooking. However, learning healthy cooking knowledge and putting the learned knowledge into real cooking prac-tice are often difficult, due to non-trivial nutritional calculation of multiple food ingredients in a cooked meal. This work presents a smart kitchen with UbiComp technology to improve home cooking by providing calorie aware-ness of food ingredients used in prepared meals during the cooking process. Our kitchen is embedded with a calorie tracker that can track the number of calories in the used food ingredients. The calorie tracker is developed based on a hybrid sensing method that integrates weight sensing from load cells and im-age processing from cameras. Thus, the system can provide real-time calorie feedback to users through an awareness display. In this thesis, we have de-signed and implemented three applications of this smart kitchen, in which each of these three applications targets a different goal in raising user awareness on (1) nutrition facts, (2) used calories, and (3) used calories in consideration of nutritional balance. For evaluation, separate user studies were conducted on each of these applications. Our user study results suggested that providing real-time calorie awareness can be an effective means in helping family cooks maintain a healthy level of calories in their prepared meals.
