Example applications:

• Creation of new musical instruments
• Create mappings between gesture and computer sounds. Control a drum machine using your webcam! Play Ableton using a Kinect!
  
• Creation of gesturally-controlled animations and games
• Control interactive visual environments like Processing or Quartz Composer, or game engines like Unity, using gestures sensed from webcam, Kinect, Arduino, etc.
  
• Creation of systems for gesture analysis and feedback
• Build classifiers to detect which gesture a user is performing. Use the identified gesture to control the computer or to inform the user how he's doing.
  
• Creation of real-time music information retrieval and audio analysis systems
• Detect instrument, genre, pitch, rhythm, etc. of audio coming into the mic, and use this to control computer audio, visuals, etc.
  
• Creation of other interactive systems in which the computer responds in real-time to some action performed by a human user (or users)
• Anything that can output OSC can be used as a controller
• Anything that can be controlled by OSC can be controlled by Wekinator

The Wekinator includes:

• real-time feature extraction 
  • built-in feature extraction from audio input, USB game controllers, laptop motion sensors, and webcams
  • ability to plug-in other feature extractors that output OSC, for getting control data from Arduino, Kinect, Processing/OpenCV, iPhone/iPad running TouchOSC, or other programs written in Java/C++/Python/you-name it
• Weka's implementations of discrete and continuous supervised learning methods
  • including neural networks, AdaBoost, support vector machines, k-nearest-neighbor, and decision trees
• A GUI for managing input devices, feature extraction, selection and configuration of learning algorithms, creating training examples by demonstration, and the training and running of machine learning models 
  • allows users to interactively create machine learning models from scratch, without any programming
• built-in support for ChucK sound synthesis so users can easily plug in their own ChucK code
• support for controlling other sound synthesis, visuals, or other processes in other programs or environments that can receive OSC
  • e.g., control Processing, Max/MSP, PD, SuperCollider, Ableton, Quartz Composer, Unity 3D game engine, ... or custom programs written in Java/C++/Python/you-name-it.
