Answer: Japan
Notes: A professor of Japan has developed a prototype of a lickable TV screen which can imitate food flavors. The technology has been named Taste the TV (TTTV), which uses a carousel of 10 flavour canisters that spray 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 experience. This prototype is seen as a step towards achieving multi-sensory viewing experience in the media industry.
