Graphical tool for heart rate Variability Analysis in Response to audioVisual stImuli. gVarvi supports all heart rate monitors that use [ANT+] (http://www.thisisant.com/) protocol and Polar Wearlink®+ over Bluetooth. gVARVI is fully functional on Linux Systems. Windows support is experimental.

To work propertly, gVarvi needs some external software:

• [Python] (https://www.python.org/downloads/) (version 2)
• [wxPython] (http://wxpython.org/download.php)
• [PyGame] (www.pygame.org/)
• [PyBluez] (https://pypi.python.org/pypi/PyBluez/)
• [Matplotlib] (http://matplotlib.org/)
• [PyUSB] (http://sourceforge.net/projects/pyusb/) (1.0.0a2 or later)
• [Pyserial] (https://pypi.python.org/pypi/pyserial)
• [msgpack-python] (https://pypi.python.org/pypi/msgpack-python/)
• [VLC] (http://www.videolan.org/vlc/)

If you want to use Pygame instead of VLC for video playback you need to change this line

     from player.VideoPresentationPlayerVLC import VideoPresentationPlayer

by this one

     from player.VideoPresentationPlayerPygame import VideoPresentationPlayer

at [VideoPresentation] (gvarvi/activities/VideoPresentation.py) module. Notice that Pygame only supports MPG video format (more info [here] (http://www.pygame.org/docs/ref/movie.html))

Binaries for debian based distributions are available [here] (https://github.com/milegroup/gVarvi/tree/master/dist)
