In this paper, we propose a tabletop system for affecting our perception of satiety and controlling energy intakes by controlling a size of a projected image around the food. We hypothesized that ambiguous perception of satiety can be applied to control our food intake. Given that estimating portion size is often a relative judgment, apparent food volume is assessed according to the size of neighboring objects such as many cutleries. Especially, the effect of the size of dish on food intake has been debated. Based on the knowledge, we constructed a tabletop system which projects virtual dishes around the food on it, in order to change the assessed apparent food volume interactively. Our results suggest that the size of virtual dish change the perception of satiety and the amount of food consumption.
