May 27 (UPI) — Researchers have developed a “licking screen” device that reproduces the taste of food when it comes into contact with a human tongue, according to a recent study published by the American Computer Association’s (ACM) Digital Library.
Digital devices that simulate the taste of virtual food
Homei Miyashita, a researcher at Meiji University in Japan, created the virtual taste device. The device uses electrolytes inserted into a five-color gel that controls the strength of five basic flavors, including bitters, salts, fresh tastes, sweets, and acids.
Microscopic particles are activated by charge when they migrate, which produces electrophoresis, and this virtual taste is provided by electrophoresis. When the device’s five electrolyte tubes touch the tongue, one subjectively perceives all five tastes. However, when the device passes at a lower voltage, it produces a different charge, and some flavors may be magnified, while others may be reduced.
Compare a virtual taste to a picture
Miyashita compares the device’s ability to enhance taste perception to the ability of humans to perceive images or monitors. When our eyes see beautiful images on the screen, we know that each image is the result of a combination of red, blue, and green pixels of different intensity, we can still form an emotional response.
“Optical displays use three basic pigments to produce arbitrary colors, similar to this device, which synthesizes and distributes any taste of data collected by taste sensors,” Miyashita said in his research paper. “
Miyashita calls his device a “sushi synthesizer.” In one of his experiments, he enhanced the experiment’s experience by wrapping dried purple vegetables around an electronic synthesizer, while he also enhanced the sour and salty taste to more accurately mimic the taste of sushi.
Virtual food ready to taste
Miyashita adds that the synthesizer “doesn’t need to put anyfood in your mouth to give people a taste ranging from rubber candy to sushi.” “But there is an embarrassment that cannot be ignored: if we get meaningful experiences from simulated objects, are we really just being deceived by illusions?”
As a new concept, the new version of the device will allow passengers to enjoy virtual consumption on flights without additional services, without the need to set up a canteen to allow them to taste delicious dishes such as ice cream sundae and raw steaks.
