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 ordistracts its original function, and (2) whether the object’s digital interaction matches orconflicts 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.
