Prototype uses carousel of canisters to create flavour samples on hygienic film over flatscreen TV

A Japanese professor has developed a prototype lickable TV screen that can imitate food flavours, another step towards creating a multisensory 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.
