Japan professor creates lickable TV screen that imitates food flavours

A Japanese professor has developed a prototype lickable TV screen that can imitate food flavours, another step towards creating a multi-sensory viewing experience.

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.

“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 said.

Miyashita works with a team of about 30 students that has produced a variety of flavour-related devices, including a fork that makes food taste richer. He said he built the TTTV prototype himself over the past year and that a commercial version would cost about 100,000 yen ($875) to make.

Potential applications include distance learning for sommeliers and cooks, and tasting games and quizzes, he said.
