World's first: Tech uses human-augmentation platform for sharing taste perceptions

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 analysed 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.

This technology will be introduced during the ‘docomo Open House '24’ online event beginning on January 17.
