    ABSTRACT: The paper discusses a kitchen that intelligently senses cooking activities and provides realtime nutritional information helps facilitate healthy cooking by letting family cooks make informed decisions. It creates opportunities to embed pervasive computing in a smart kitchen to facilitate healthy cooking.

    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 practice 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 awareness of food ingredients used in prepared meals during the cooking process. Our kitchen has sensors to track the number of calories in food ingredients, and then provides real-time feedback to users on these values through an awareness display. Our user study suggests that bringing calorie awareness can be an effective means in helping family cooks maintain the healthy level of calories in their prepared meals.

    ABSTRACT: To realize Weiser's vision of ubiquitous computing, a popular approach has been to create so-called smart living objects, which are everyday objects in our living environment augmented with digital technology. In this paper, we survey different smart living objects and classify their design choices into different types of digital enhancement. These design choices are about choosing the relation between the object's digital enhancement and its traditional use - (1) whether the object's digital function enhances or distracts its original function, and (2) whether the object's digital interaction matches or conflicts with its original interaction. Finally, we formulate design heuristics that new digital enhancement should consider the object's traditional function and interaction method, and avoid conflict between the digital enhancement and the traditional use.

    ABSTRACT: We present a smart kitchen that can enhance the traditional meal preparation and cooking process by raising awareness of the nutrition facts in food ingredients that go into a meal. The goal is to promote healthy cooking. Our smart kitchen is augmented with sensors to detect cooking activities and provides digital feedbacks to users about nutritional information on the used food ingredients. We have created a preliminary prototype for evaluation, and the result is promising.

    ABSTRACT: This study has created the Playful Tray that adopts Ubicomp and per- suasive techniques into play-based occupational therapy for reducing poor eat- ing behavior in young children after they reached their self-feeding age. The design of the Playful Tray reinforces active participation of children in the ac- tivity of eating by integrating digital play with eating. Results of a pilot user study suggest that the Playful Tray may improve child meal completion time and reduce negative power play interactions between parents and children, re- sulting in an improved family mealtime experience.
