Python tobii_research – subscribe_to

[Hanan]

Hi,

I’m trying to use the function subscribe_to for my Tobii eye tracker 5 in my python code and my callback function wants a call at all.
maybe someone can help?

Connection:

                found_eyetrackers = tr.find_all_eyetrackers()
                my_tobii = found_eyetrackers[0]

subscribe:

my_tobii.subscribe_to(tr.EYETRACKER_GAZE_DATA, callback=gaze_data_callback, as_dictionary=True)

gaze_data_callback:

 def gaze_data_callback(gaze_data):
    global media_player, stimeSinceStart, global_gaze_data
    currentTimeSinceStart = media_player.get_time() / 1000
    stimeSinceStart.append(currentTimeSinceStart)
    global_gaze_data = gaze_data
    print(currentTimeSinceStart)
    print(gaze_data)

I’m calibrate by calling Tobii.Configuration.exe -C through cmd.

Thank you for your help!

Hi @hananw, The Tobii Pro SDK Python API is only available for Tobii Pro Trackers. The only SDK that is compatible with the Tobii ET5 is the Tobii Stream Engine which you need to apply for access via the form @ https://developer.tobii.com/software-downloads/
