Change in the Amount Poured as a Result of Vibration When Pouring a Liquid

Visual and tactile stimulation are known to affect the experience of eating and drinking. In this study, we focused on the vibration of a Japanese Sake bottle when used to pour liquid. We manufactured a device that can be attached to the neck of any plastic bottle and investigated how beverage consumption was affected by the vibration. We found that presentation of the vibration affected the amount of poured beverage when visual and sound cues were masked.
