The latest research by the scientists at the National University of Singapore shows the possibility of sharing the taste and color of a drink over the internet, which would allow people to feel one another’s sensory experiences even when they are apart.
In an experiment, the researchers dipped a stick, loaded with pH level and color sensors, into a lemonade and then passed on the data to a tumbler filled with plain water, writes CNET. The L.E.D.s in the tumbler mimicked the lemonade color while the metal strips (electrodes) in the cup simulated and transmitted the flavor when volunteers stuck their tongues on to the electrodes.
Elaborating the potential of this technology, researcher Nimesha Ranasinghe says virtual drinks could help diabetics savor sugary drinks without taking in any sugar or people can enjoy hard drinks without getting intoxicated, notes Futurism. The team is now working on creating a full virtual cocktail with smell, taste and color all covered.
