Virtual Reality Takes a Sweet Turn: New Device Lets You Taste Cake, Study Reveals
Advertisement
Novel technology intends to redefine the virtual reality experience by expanding to incorporate a new sensory connection: taste.
The interface, dubbed ‘e-Taste’, uses a combination of sensors and wireless chemical dispensers to facilitate the remote perception of taste – what scientists call gustation. These sensors are attuned to recognize molecules like glucose and glutamate — chemicals that represent the five basic tastes of sweet, sour, salty, bitter, and umami. Once captured via an electrical signal, that data is wirelessly passed to a remote device for replication.
The study is published in the journal Science Advances.
“The chemical dimension in the current VR and AR realm is relatively underrepresented, especially when we talk about olfaction and gustation,” said Jinghua Li, co-author of the study and an assistant professor of materials science and engineering at Ohio State. “It’s a gap that needs to be filled and we’ve developed that with this next-generation system.
