“Meta Cookie” by Narumi, Kajinami, Tanikawa and Hirose

So far, 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 makes it difficult to build up a gustatory display.

Our research utilizes the complexity of cognition mechanism for gustatory sensation, in order to create a pseudo-gustatory display, which induces cross-modal effect by presenting scent. Therefore, for the realization of a novel gustatory display system, we aim to establish the method for letting humans feel various tastes without changing chemical substances by changing only accompanying information. In this paper, we propose the method to change perceived taste of a cookie when they eat by changing appearance and smell with augmented reality technology.
