Using Tobii pro SDK Python

[StoyanGanchev]

Hi,
From a while ago I have been trying to retrieve information about gaze position on a screen using the Tobii pro SDK and a Tobii eyetracker 4c, but the only thing I manage to get is the name and the serial number.
I want to ask if there is some further permission I need to get in order to retrieve information about the gaze point.
If anyone has already done such thing, please help.
I put the code I use below:

import tobii_research as tr
import time
found_eyetrackers = tr.find_all_eyetrackers()
my_eyetracker = found_eyetrackers[0]
print("Address: " + my_eyetracker.address)
print("Model: " + my_eyetracker.model)
print("Name (It's OK if this is empty): " + my_eyetracker.device_name)
print("Serial number: " + my_eyetracker.serial_number)
def gaze_data_callback(gaze_data):
    # Print gaze points of left and right eye
    print("Left eye: ({gaze_left_eye}) \t Right eye: ({gaze_right_eye})".format(
        gaze_left_eye=gaze_data['left_gaze_point_on_display_area'],
        gaze_right_eye=gaze_data['right_gaze_point_on_display_area']))
my_eyetracker.subscribe_to(tr.EYETRACKER_GAZE_DATA, gaze_data_callback, as_dictionary=True)
time.sleep(5)
my_eyetracker.unsubscribe_from(tr.EYETRACKER_GAZE_DATA, gaze_data_callback)

4C is a consumer tracker. Tobii Pro SDK only supports the Tobii Pro line of trackers. The list of supported trackers is here: https://developer.tobiipro.com/tobiiprosdk/supportedeyetrackers.html
