gazesdk

Python language bindings implemented in Cython for Tobii GazeSDK C API.

This is a work in progress. Backwards incompatible changes are possible in the near future. Currently only basic tracking functionality is supported, See TODO below for planned changes.

Note that use of this software is not officially supported by Tobii.

Example

The following example prints normalized screen coordinates for first 20 events.

from gazesdk import *

url = get_connected_eye_tracker()
t = Tracker(url)
t.run_event_loop()

t.connect()
t.start_tracking()

for _ in range(20):
    data = t.event_queue.get()
    print (data.left.gaze_point_on_display_normalized, 
    	   data.right.gaze_point_on_display_normalized)
    t.event_queue.task_done()

t.stop_tracking()
t.disconnect()

t.break_event_loop()

Installation (Windows)

Dependencies: Python 2.7 32 bit

  1. From "Releases" download gazesdk-win32.zip
  2. Extract the pyd file
  3. Copy "TobiiGazeCore32.dll" in the same directory
