Erotic licking content?
A prototype “lickable” TV screen which can mimic food flavors has been developed by a Japanese professor.
The device, called Taste the TV (TTTV), uses a carousel of 10 flavor canisters that spray in combination to create the taste of a particular food. The flavor sample then rolls onto a “hygienic film” over a flat TV screen for the viewer to lick.
Professor Homei Miyashita of Meiji University, suggested it could be used to train cooks or sommeliers remotely,
If made commercially, the TV would cost $875 (£735), he estimated.
“The goal is to make it possible for people to have the experience of something like eating at a restaurant on the other side of the world, even while staying at home,” he told Reuters.
He is reportedly in talks with manufacturers about other possible applications of the flavour-spraying technology, such as adding flavours to toast.
The professor envisages a world of downloadable “taste content”.
