Some weeks ago I stumble across a really cool video where Hatsune Miku performs live at the 39′s Giving Day concert in Japan. There are also three other characters performing, but I don’t know their names. ^^

Check out Miku’s performance below:

The first time I watched the video I saw it in very low resolution, so I couldn’t really tell how the technology to show her worked. At first I thought that maybe it was a real actor in a costume or a robot, since Japan is a really robot friendly country. Then I googled to find answer and I found this article – stating that Miku on the concert was a 3D hologram. But I wasn’t sure if the article was right, which it wasn’t. Because I thought it sounded a bit too advance with 3D hologram.

If you watch the performance in higher resolution you can easily see that she is very pixely at close distance, which proves that she isn’t real or a robot. It is also possible to see that there is a huge frame on the stage with a net, that Miku is projected on with a camera from behind. So in reality it is only a 2D image on a net. However, it still looks awesome and the spirit on the concert is fantastic.
