"fragra - an interactive olfactory game system"

　"fragra" is an interactive game which you can experience "fragrance" of some foods, for examples: apples, bananas, melons, peaches and even breads. Although the olfaction is a rare theme in virtual reality domain, players can interact with fragrances easily.

　With Olfaction Display Device:Kaori-chan, players can smell objects displayed on HMD(Head Mounted Display). (Players can catch the objects with their virtual right hands.)

Game tutorial

　There is a mysterious tree which bears many kinds of foods. Players can catch them by moving their right hands. When they catch one of foods and move it in front of their nose, they can smell something. The fragrance they smell does not always correspond to the appearance. So they have to distinguish whether the fragrance corresponds to the appearance or not.
