Serious dietary education system for changing food preferences "food practice shooter"

We propose Serious Dietary Education System for Food Preferences system using eating food. "Eating food and mastication" and smiling, is required to clear the game. This system is a preferences shooting game. A user has to eat some food that most children may dislike, for example, tomatoes, carrots and bell peppers to beat monsters that on the screen. The number of bullets is settled by the number of chews (mastication) and the bullets are charged by a gun device by smiling. We aim to change food presences with this system.
