Creating an impression of virtual liquid by modeling Japanese sake bottle vibrations

It is known that visual, auditory, and tactile modalities affect the experiences of eating and drinking. One such example is the “glug” sound and vibration from a Japanese sake bottle when pouring liquid. Previous studies have modeled the wave of the vibration by summation of two decaying sinusoidal waves with different frequencies; we examined the validity of this model by subjective evaluation. Furthermore, to enrich expression of various types of liquid, we included two new properties of liquid: the viscosity and the residual amount of liquid, both based on recorded data.
