gVarvi

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.

Dependencies

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)

• [msgpack-python] (https://pypi.python.org/pypi/msgpack-python/)
• [VLC] (http://www.videolan.org/vlc/)

How to change playback backend

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))
