Balanced Glass Design: A flavor perception changing system by controlling the center-of-gravity

In this paper, we propose Balanced Glass Design, a system to change flavor perception. The system consists of glass-type device shifting its center of gravity in response to the user’s motion which allows drinking a beverage with a virtual perception of weight through drinking motion. We thought It’s possible to intervene in the user’s perception of flavor by displaying virtual weight perception, and so conducted experiments on weight perception and demonstrations as a user study. This paper describes the system design, the result of experiments, and comments obtained through a user study.
