The Alteration of Gustatory Sense by Virtual Chromatic Transition of Food Items

摘要

When we visually recognize food items, their color influences the impression of their taste, because the gustatory sense is affected by other senses such as smell and eyesight. In this study, in order to control the gustatory sense of human beings, we examined the influence on gustatory sense by giving a virtual chromatic transition of food through Head-Mounted Display. The experiment was conducted under six conditions that changed three factors: "before or after eating", "viewing through HMD or naked eyes", "with virtual chromatic transition or without". As a result, we confirmed that the difference in the amount of visual information influenced the impression of food items before eating. It is expected to realize more applicative control of the gustatory sense by analyzing this difference.
