Hatsune Miku sings ’Tell Your World’ along with my piano

* This work was exhibited at Maker Faire Tokyo 2015. * This is an Augmented Reality program with an interactive feature. Computer recognizes human piano play, and Hatsune Miku sings along with it. This program can follow bad piano play including misstouches or temporal instability. 3D polygon model display, animation and physics simulations are based on the source code from ’ARToolKit_MMD’ software. I would like to thank the authors of the music, polygon model and ’ARToolKit_MMD’. (NicoNicoDouga: sm239881
