Researchers at Ohio State University have developed a device that allows people to taste flavors remotely using virtual reality goggles. The device uses microfluidics and miniature pumps to transmit the taste of foods and drinks from a distance.
The device was tested with volunteers who were able to accurately identify flavors such as coffee, fried eggs, cake, lemonade, and fish soup. However, simulating all tastes is challenging due to the complexity of human taste perception. The researchers are now investigating ways to improve the device, including adding vibrations to simulate texture and using scents to enhance the sensory experience.
The potential applications of this technology include online grocery shopping, where customers could virtually taste-test hot sauces before buying them. It also raises questions about why we can’t currently see or hear what’s going on while eating remotely. The researchers are confident that their device will continue to evolve and become more compact, potentially even wearable like a locket or pendant in the future.
