About ‘tele-taste’ TV screen

• The device, called Taste the TV (TTTV), uses a carousel of 10 flavour canisters that spray in combination to create the taste of a particular food. The flavour sample then rolls on hygienic film over a flat TV screen for the viewer to try.
• In the COVID-19 era, this kind of technology can enhance the way people connect and interact with the outside world, said Meiji University professor Homei Miyashita.
• Its 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.
