"A fictional 16-year old anime character by the name of Hatsune Miku has had chart topping hits and has been featured in online videos receiving millions of views. This has subsequently been followed by live performances in which the character is displayed as a hologram in front of a live band to the throngs of cheering fans. If that wasn’t surprising enough the character’s voice is not even human. It is synthetic and completely produced by a computer."
Some think it's creepy. I dunno, I just think it's cool. And astonishing. (Not even the voice is real... dang.)
It'll be interesting to see what idorus will appear as the tech matures. Of course the main difference between Gibson's idoru character and this real (unreal) one is that so far the real thing does not have artificial intelligence and self-awareness. So far. That's a very tough problem in computing.
Here's a video with more info on her. It's in Japanese, and though it has some instruction on how to get English subtext or audio (there's a Settings selection in the resolution menu for some reason), I didn't get that to work.
...much of it is available in HD ... try searching YouTube for 'Meltdown Live in HD (1080p 1920 x 1080)'!
Unfortunately, it gives the game away at this resolution though ... it would appear that it is NOT a hologram, but is actually a back-projected image onto a translucent screen.
The bright pinpoints of light originating behind 'her' from within the band are the projection unit, and around 1.06ish, you can briefly see the glass-like screen stretching across the stage, onto which they are creating the image.
