Personal OrchestraThe goal of the Personal Orchestra series of projects is to adapt this centuries-old interaction metaphor to digital multimedia so that everyone may enjoy the wonderful experience of conducting world-famous orchestras.
Our primary research goals for this line of research are:
- innovative interfaces for musical expression
- gesture recognition (capturing the physical user movements)
- gesture modelling and interpretation
- real-time interactive audio and video time-stretching without pitch-shifting artifacts
- time design and frameworks for time design of multimedia
- A permanent demo installation of the Personal Orchestra exhibit is now set up in our lab (operating instructions) (Aug 14, 2014)
- Today, the HOUSE OF MUSIC VIENNA launched our redesigned Personal Orchestra exhibit. Using an infrared baton, visitors can conduct the Vienna Philharmonic by controlling speed, volume, and the emphasis of different instrument sections. The new system now features our PhaVoRIT continuous real-time high-quality audio stretching, six new recordings of the orchestra in full HD video, an electronic music stand displaying the score, and helpful hints by maestro Zubin Mehta. Our original exhibit was installed in 2000, and has been used by 1.5 million visitors since, making it the most successful station in the house, and a top tourist attraction - see the TV news report (Nov 27, 2009 --video cached on our server, 11.6 MB).
- Documentary about "Haus der Klänge" (House of sound) and a interview on personal orchestra (ZDFinfokanal, July 2007, video, 28 MB)
- Coverage of Personal Orchestra 1 in Vienna City Guides (English+German, 2006)
- Documentary about Personal Orchestra 1 from "Abenteuer Erde" on 19 April 2006 (high (41 MB) /low (18 MB) resolution)
Personal Orchestra 13: The Virtual Conductor '14 (2013-2014)HOUSE OF MUSIC VIENNA, Austria
The 2014 version of this system was developed primarily with the following goals in mind:
- exchanging the active infrared baton for a passive baton, which will be tracked using standard motion caption hardware, to reduce maintenance load on the active batons
- developing reliable tracking and conducting motion classification algorithms
- updating the software to be compatible with newer versions of the underlying operating system
- updating video and audio rendering to use modern APIs and provide smoother playback
- tighten the closed loop for the conducting speed tracking to allow better and more fine grained tempo control
- allow a wider spatial range of conducting gestures without losing dynamic range
These changes make the most successful exhibit in the Vienna House of Music even more enjoyable for visitors and much less maintenance prone for the museum staff.
HOUSE OF MUSIC VIENNA, Austria
This system was designed for the HOUSE OF MUSIC VIENNA. It was opened to the public on Nov 27, 2009. It replaced our original PO1 exhibit installed there in 2000, which had been used by 1.5 million visitors since, making it the most successful station in the house, and a top tourist attraction.
Using an infrared baton, visitors can conduct the Vienna Philharmonic by controlling speed, volume, and the emphasis of different instrument sections. The new system features
- the MICON electronic music stand that shows the score, highlighting the current position and emphasized instrument section, and turning pages in a 3D animation,
- six new recordings of the orchestra in full HD video,
- greatly improved conducting fidelity, giving visitors the tightest control over the orchestra of all our systems, including the ability to stop conducting for a fermata,
- our PhaVoRIT continuous real-time high-quality audio stretching,
- up to six different instrument sections that can be emphasized by conducting towards them,
- helpful hint video scenes by maestro Zubin Mehta explaining how best to conduct each piece.
One of the major new research and development challenges in this version was to create a video pipeline architecture that can display full HD video at rapidly varying speeds from 0 to 200% without any stuttering or other artifacts. The system is based on the advanced video rendering subsystem inside Mac OS X.

This system was developed for a children's museum. The main new feature developed for this project was an adaptive gesture recognition to accommodate both regular conducting gestures by adults and irregular conducting movements by young children.

You're the Conductor was our second generation conducting system designed specifically for kids (but it works great for adults too!). It features "Stars and Stripes Forever" performed by the Boston Pops/Boston Symphony Orchestra.
You're the Conductor offers an improved technical framework over You're the Conductor, especially in the area of time-stretching audio. Audio is processed in real-time using an improved phase vocoder algorithm, resulting in increased responsiveness, audio quality and tempo range over the Virtual Conductor. Movies are stored as standard QuickTime movies with uncompressed PCM audio.
The key research contributions were:
- first conducting system specifically designed for children, featuring an audio and video recording for an orchestra.
- design and implementation of a technical framework for real-time interactive audio time stretching without pitch shifting artifacts.

The Virtual Conductor was the world's first system that allowed users to conduct an actual audio and video recording of an orchestra. It has become a highlight of the HOUSE OF MUSIC VIENNA where it has been a permanent exhibit and museum highlight ever since the museum's opening in June 2000. It features exclusive performances from the world-famous Vienna Philharmonic Orchestra.
Users conduct the Vienna Philharmonic using a Buchla Lightning II infrared baton that sends MIDI data to a host computer performing the gesture recognition. Gestures are interpreted as simple up-down motions and translated to speed, volume and instrument emphasis which are then sent to a second computer responsible for processing the audio and video for display. Movies are stored as a multi-track QuickTime movie including a series of pre-processed, pitch-shifted tracks. By switching between these different audio tracks and varying the playback speed, the audio is time-stretched without any pitch-shifting artifacts.
The key research contribution was:
- first system to let a human conduct an actual audio and video recording.
