Virtual reality (VR) can, in its own imperfect ways, transport a user into distant experiences. One thing VR can’t yet do, however, is simulate the experience of eating lunch. But that could change thanks to a new “bio-integrated gustatory interface” device called e-Taste.

Researchers from Ohio State University created a small electromagnetic pump connected to a liquid channel of chemicals that, when mixed in the right ratios, can approximate the taste of coffee, lemonade, cake, and other food and drinks. That newly crafted chemical liquid is then pushed through via a gel. Users ultimately experience the taste as a liquid that sits in their mouth. And while an initial group of human test subjects struggled to accurately differentiate between different taste profiles, the study suggests a future VR steakhouse experience might not be as far-fetched as it sounds.

The researchers tested their new device on 10 volunteers and received mixed results. On the positive side, the test subjects were able to differentiate between various sour taste profile intensities with approximately 70 percent accuracy. The tests were less conclusive though when researchers asked participants to distinguish between flavors intended to represent cake, fried egg, coffee, and fish soup. That discrepancy is not necessarily due entirely to poor device performance, though. Even in the physical world, taste is inherently subjective. Factors such as smell, memory, and visual cues can influence how we perceive food. Two people might experience the taste of the same meal slightly differently. “Taste and smell are greatly related to human emotion and memory,” added one of the researchers. “So our sensor has to learn to capture, control, and store all that information.”

The e-Taste researchers believe their device could also have applications beyond video games. Theoretically, the technology could one day allow users to virtually taste-test items before ordering them. Medical professionals might also use the device to remotely assess whether patients have lost certain aspects of taste, which could be an early indicator of illness. Additionally, the device could serve as an aid in reintroducing taste sensations to individuals with certain neurological disorders or illnesses, such as long COVID, that have impaired their ability to taste food.
