NTT DOCOMO, Miyashita Laboratory of the School of Interdisciplinary Mathematical Sciences, Meiji University,1 and H2L announced that they have developed a technology that enables taste information to be shared between people via a human-augmentation platform developed by DOCOMO.
The solution combines DOCOMO's human-augmentation platform with Miyashita Laboratory and H2L's technology for reproducing tastes. The technology, which DOCOMO believes is the world's first3 of its kind, comprises a sensing device that detects data on a person's perception of taste, a human-augmentation platform that shares the taste by taking into account individual differences in sensitivity, and a "driving" device that reproduces the taste for enjoyment by others.
Specifically, after a specific taste is analyzed and quantified, a proprietary algorithm on the human-augmentation platform estimates how the first person perceived the taste using approximately 25 data points, and then the taste is reproduced using the driving device for sharing with others.
The driving device reproduces the five basic tastes (sweet, sour, salty, bitter and umami) using 20 types of base liquids. For related tastes, it uses a base solution.4 As a result, tastes that are difficult to convey in words can be shared more clearly with others.
The technology is expected to be used in virtual experiences in the metaverse space, which until now has been a purely visual and auditory world, as well as in combination with film and animation. The inclusion of taste expressions will enable users to enjoy extra-rich content and experiences with an unprecedented sense of presence.
Going forward, DOCOMO, Miyashita Laboratory and H2L will develop solutions for sharing taste perceptions based on their new technology, aiming to create new communication culture and providing new value for enhanced quality of life.
