zehndetails GmbH, Head of Frontend R&DDec. 2013 ~ Sep. 2014
The company aims at developing an interactive system to discover digital conference posters with intuitive touch interfaces. We explored various touch actions like pinching and dragging to provide better interface to discover large number of scientific conference posters. The system also can present videos as scientific evidences, which was difficult with traditional paper posters. I was responsible for developing interactive iPad app, which also drives external TV as the second screen for the content presentation.Das Terminal

Statistical Synthesis and Analysis of Music PerformanceMay 2011 ~ current
As a Ph.D. candidate at Audio Communication Group, TU Berlin, I am working on developing statistical models of expressive music performance with machine learning. This research would be useful for developing diverse music intelligent systems, such as content-based music search engine, music navigation and expressive sound synthesis systems. Furthermore, the research will provide a new approach for music interpretation studies with statistical methods.
POLYHYMNIA: a fully automated piano performance systemApr. 2009 ~ March 2011
This is the main achievement during my Master's course. The system is able to automatically render a given piano piece with a certain performance style. Statistical models of style-aware musical expressions are trained with human expressive piano performances. It is probably the first automatic piano performance system, which can learn polyphonic expression in piano music. Subjective listening tests indicate that the rendered performances sounded like human piano performances, and individual performance styles could be identified.
ORPHEUS: automatic song composition with Japanese lyrics,Sep. 2008 ~ March 2009
ORPHEUS automatically composes a song with Japanese prosody information, and render it with artificial singing voices. I worked on improving the system by adding the ability of composing songs with musical structures and proposed a method based on combining pre-defined rhythms, chords and accompaniment patterns. The system is currently maintained by SOUND lab. of the University of Tokyo.
