Gesture Recognition Toolkit

Welcome to the main wiki page for the Gesture Recognition Toolkit.

The Gesture Recognition Toolkit (GRT) is a cross-platform, open-source, C++ machine learning library that has been specifically designed for real-time gesture recognition.

In addition to a comprehensive C++ API, the GRT now also includes an easy-to-use graphical user interface:

You can find out more about the GUI here.

The GRT has been designed to:

  • be easy to use and integrate into your existing C++ projects
  • be compatible with any type of sensor or data input
  • be easy to rapidly train with your own gestures
  • be easy to extend and adapt with your own custom processing or feature extraction algorithms (if needed)

The GRT features a large number of algorithms that can be used to:

  • recognize static postures (such as if a user has their hands in a specific posture or if a device fitted with an accelerometer is being held in a distinct orientation)
  • recognize dynamic temporal gestures (such as a swipe or tap gesture)
  • perform regression (i.e. continually map an input signal to an output signal, such as mapping the angle of a user's hands to the angle a steering wheel should be turned in a driving game)

The GRT currently works across several operating systems including:

  • Windows (Tested on Windows XP, Windows 7)
  • OS X (Tested on 10.7)
  • Linux (Tested on Ubuntu 12)

The current development build of the GRT contains machine-learning algorithms such as:

In addition to the machine-learning algorithms, the GRT also contains a large number of pre-processing, post-processing, and feature-extraction algorithms such as:

The current development version of the GRT can be downloaded from http://code.google.com/p/gesture-recognition-toolkit/.
