Python Wrapper - QuickLink2 API

Yes!

Here is where most of the development has been happening:

https://github.com/peteristhegreat/ioHub/tree/master/devices/eyeTrackerInterface/HW/EyeTech/QuickLink

It has been tested with a VT2/VT3 (AEye) and Python 3.4 64 bit. For viewing the images in this example, MatPlotLib and NumPy were used.

For it to function properly, make sure you are using the same bitness between python and the QL2 libraries.

QL2 64 bit DLL info and download

ToDo

• Settings
• Calibration
• PyQt example?

Running the Example

Plug in an eye tracker, make sure it is working with Quick Glance... Close Quick Glance and run:

python quicklink2.py
