    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(
    my_eyetracker.subscribe_to(tr.EYETRACKER_GAZE_DATA, gaze_data_callback, as_dictionary=True)
    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
