Cymatics Cup: Shape-Changing Drinks by Leveraging Cymatics

To enhance the dining experience, prior studies in Human-Computer Interaction (HCI) and gastrophysics have demonstrated that modifying the static shape of solid foods can amplify taste perception. However, the exploration of dynamic shape-changing mechanisms in liquid foods remains largely untapped. In the present study, we employ cymatics, a scientic discipline focused on utilizing sound frequencies to generate patterns in liquids and particles-to augment the drinking experience. Utilizing speakers, we dynamically CHI '24, May 11-16, 2024, Honolulu, HI, USA Chen et al.

reshaped liquids exhibiting ve distinct taste proles and evaluated resultant changes in taste perception and drinking experience. Our research objectives extend beyond merely augmenting taste from visual to tactile sensations; we also prioritize the experiential aspects of drinking. Through a series of experiments and workshops, we revealed a signicant impact on taste perception and overall drinking experience when mediated by cymatics eects. Building upon these ndings, we designed and developed tableware to integrate cymatics principles into gastronomic experiences.
