With the change in our diet, importance was placed on dietary education, and various systems for dietary education have been proposed. However, there has been no system that deals cooking tools. This article, therefore, proposes a peeler-type device, ‘TamaPeeler’, in the hypothesis that touching the food directly and being involved in cooking would raise their interest in food. TamaPeeler detects motions of peeling vegetables, and simultaneously makes various peeling sounds from the wirelessly connected smart phone. As we observed children during its exhibit, we have observed them proactively peeling vegetables, or showing interests in peeling other vegetables, and it was suggested that using an interactive cooking tool can raise the interests of children in food and diet.
