Electrode Lets People Taste In Virtual Reality
Temperature sensitive electrical pads make a user's tongue believe they are tasting something not there
Nimesha Ranasinghe, a research fellow at the National University of Singapore, and his colleague Ellen Yi-Luen Do, a professor at the School of Industrial Design and the School of Interactive Computing, experimented with thermal stimulation to trick human taste buds. Participants would place the tip of their tongue on an electronic surface and feel a different temperature. When the tongue was exposed to the different temperatures, the participants reported a mint flavor at temperatures around 18 °C and a spicy one when around 35 °C.
