The actual news here is that Japanese telecom giant KDDI has partnered with a firm named Mawari (which means something along the lines of “surroundings” in Japanese) to create a virtual assistant you can “see” through the window of your smartphone in augmented reality, one who might automatically pop up to give you directions and interact if you point your phone at a real-world location. (You’ll also see walking directions and indoor maps in the video, but those simply appear to be packaged together as part of the proof of concept.)
If you peek the video atop this post, you can see it’s not that much more advanced than, say, Pokémon Go. But behind the scenes, the partners claim that KDDI’s 5G network, Amazon’s low-latency AWS Wavelength edge computing nodes, and a proprietary codec from Mawari combine to let “digital humans” stream to your phone in real time instead of running natively on your phone’s chip.
