   Abstract—Cooking is the theme that causes interest to everyone
as element that is essential in life. Everyone try to cook, but fire
and knifes are dangerous to handle for children. So children are
felt difficult to cook directly. In this paper, we describe about
development of cooking system that gives imaginary cooking
experience to children. Our cooking system consists of two major
technologies (Augmented Reality, Tabletop display) that can
interact with user. Using augmented reality technology gives to
user more arresting and accessible virtual cooking environment.                    Figure 1 overview of cooking system
Using tabletop display that provides multi-touch can provide
interaction between user and the cooking system effectively.
