The Mobile World Congress (MWC) is primarily a pow-wow for the big-wigs of the telecom industry, but far from the main thoroughfares of the vast conference there are always hidden tech gems.
Here are some of the most offbeat products spotted by AFP.
A clone at last
As advertising slogans go, "you can live forever" is up there with the best.
That is how Memori Yamato explains the "personalised AI clone" from her Japanese company Alt Inc.
"Your descendants can continue to speak and interact with you, even after your death," Yamato told AFP.
The idea is to upload as many videos, images and audio samples as you can while alive.
The system will use it to generate an AI mirror, cloning you forever in the digital world.
"It will look like you, it speaks in your voice, and it even thinks like you," she said.
The idea has been nine years in the making, she said, and feedback from early users suggests the technology has nailed appearances and voices.
A dog's nose carries similar identifying traits as a human fingerprint.
South Korean start-up Petnow took this info and ran with it — like a dog after a stick — to create a biometric database of pets based on noseprints rather than microchips.
"Since the 1940s, we've known that dogs' noses worked a little like fingerprints," the firm's Peter Jung told AFP.
He explained that around 100 000 animals are abandoned each year in South Korea, often because owners cannot afford vet bills.
"Less than 10 percent have chips because people don't like the process," he said.
Petnow just requires a photo and AI does the rest, ensuring the photos are good enough for identity purposes.
Jung says 50,000 pet owners have signed up since last year and he hopes the government will change the rules to allow his system to replace chips.
And cat lovers need not worry. Their noses may be too petite to be identifiable, but each feline face is unique and can be used in the system.
A staple from the pages of science-fiction and the dream of the super-rich, flying taxis could be with us as soon as 2025, according to SK Telecom.
At the MWC, some attendees got an early taste, thanks to VR headsets and a real-life prototype complete with juddering seats.
Halfway between a helicopter and a drone, the craft has six electric motors that allow vertical take-offs and landings.
