Reposting a scented bouquet is no longer a joke. Scientists from the USA and China created Centroni: an electronic nose with AI detects the smell, transmits data over the network, and a device at the other end reproduces the aroma. Everything is automatic, the receiver can be built into a bracelet or pendant. In the tests, 14 volunteers smelled coffee, beer, wine, cake and an orange. Single scents were detected in about 73% of cases, pairs - in 71%. The system processed a simple signal in 0.6 seconds, complex smells - up to several tens of seconds. The authors even put together a cup with taste and aroma for virtual drinks. But it will not be possible to send your favorite perfume one to one: the system selects a scent from a pre-loaded set, and does not copy its chemical composition. It has not yet been tested outside of the lab. - The evolution of virtual gifts continues.
