Recent studies have revealed that consumption of food and beverages is influenced by both its actual volume and external factors during eating and drinking. In this paper, we hypothesized that the augmented reality system which elongate and contract the apparent height of a cup can change our beverage consumption effectively. We conducted two user studies to confirm whether the system can change our drinking behavior and beverage consumption in short and long term. The result of the short-term experiment showed that the amount of one sip became significantly greater when they drank from a visually lengthened cup, and also became significantly smaller when they drank from a visually shortened cup. And the long-term experiment showed that the total amount of consumed beverage in one hour can be modified from about -14% to about 25%.
