Exploring Taste Sensation in the Metaverse: A Literature Review

Metaverse represents a hypothetical iteration of the Internet as a single immersive virtual world in which users can interact with each other. Nowadays, despite the efforts to embed sensory feedback in the metaverse scenarios, there is still a problem with doing that with chemical senses, therefore taste is not included in it. In our work, we present how the sense of taste could be implemented in a metaverse virtual world, analyzing currently developed and possible future devices eventually implementing digital taste, to induce virtual taste to users. Its hypothetical implementation would indeed break ground in digital communication such as in the videogame empire, increasing the user experience and opening a completely new era of gaming, entertainment, and media, with a predictable blast in revenues for the related industry.
