What: The Weight-Changing Cup changes Your Perception of Flavor
The relationship between taste and the appearance of a dish or beverage is widely known, but the relationship of taste to the perceived weight of the utensil has never been investigated. The weight of cup can change your perception of what you drink.
Who: Researcher Masaharu Hirose, a student at the the University of Tokyo, and their school adviser Masahiko Inami
How: Human senses can affect how taste is perceived too, as researchers discovered with a cup that can change its center of gravity and how heavy it feels in the hand.
It perches a cupholder (so the cup itself can be easily replaced for hygiene reasons) atop a handled mechanism that uses a motorized sliding weight to cleverly change its center of gravity as someone lifts the cup to their mouth to drink. As the weight slides toward the direction of the user, the cup feels heavier in hand. When it slides away, the cup feels lighter.
