- Abstract
This paper introduces the Virtual Taste Interface, a digital control system that simulates the sensation of taste (gustation) on humans. Our approach studies electrical and thermal stimulation on the tip of the human tongue to produce different taste sensations. It consists of two modules: a control system and a specially designed separate module to attach to a user's tongue. Several experimental studies were conducted with human participants based on 1) different properties of electrical stimulation such as the magnitude of current and frequency, 2) temperature change (heating and cooling), and 3) hybrid stimulation by combining both electrical and thermal stimulation. Experimental results show that the system successfully generates salty, sour, and bitter tastes among the five basic taste sensations (i.e., salty, sour, sweet, bitter, and umami). This approach deserves future investigation as the reported sensations show subjective results on a few occasions and to further study the evidence of actuating sweet taste through thermal stimulation. The novelty of this work primarily has three aspects: 1) studying the simulation and control of taste sensations achievable through the Virtual Taste Interface against the properties of electric current and change in temperature, 2) the methods of actuating taste sensations by electrical and thermal stimulation methods, either individually or in combination, and 3) the aim of introducing the human sense of taste as a digitally controllable media.
