「Meta Cookie」は、クッキーに対し、視覚情報と嗅覚情報を重畳することで、クッキーの「風味」を変化させ、食べる人が受け取る味の認識を変化させるシステムである。カメラによって認識可能なマーカのついたクッキーに、HMDを使ってさまざまなクッキーの写真を重畳表示し、さらに嗅覚ディスプレイによって匂いを付加する。この見た目と匂いの変化によって、体験者が食べたときに感じる味が変化する。体験者はインタラクションによってARクッキーに重畳する匂い・写真を選ぶことができ、好みの味のクッキーを食べることができる。 "Meta Cookie" is the world's first pseudo-gustation system which induces cross-modal effect to let humans perceive various tastes without changing chemical substances by changing only visual and olfactory information. Our system evokes cross-modal effect among vision, olfaction and gustation and let users feel that they are eating a flavored cookie although they are just eating a plain cookie with an AR marker. Gustatory information has rarely been studied in relation to computers, even though there are lots of studies on visual, auditory, haptic and olfactory information. This scarcity of research on gustatory information has several reasons. One reason is that gustatory sensation is based on chemical signals, whose functions have not been fully understood yet. Another reason is that perception of gustatory sensation is affected by other factors, such as vision, olfaction, thermal sensation, and memories. Thus, complexity of cognition mechanism for gustatory sensation as described above <b>...</b>
