Hi, I am using Tobii eye tracker 4 c and have tried capturing the gaze data but I was unable to retrieve the data using subsribe_To method in python. It is showing that the eye tracker capabilities can deliver the gaze data as below.
OUTPUT – The eye tracker can deliver a gaze data stream.
I have developed applications using both c# and python environments. Can anyone please help me fix this issue?
Gaze data in python is displaying as none and in c# it is not printing the output.18/06/2021 at 13:42 #20553Grant [Tobii]Keymaster
Hi @meghanapuppala, thanks for getting in touch. I suspect you are using the Tobii Pro SDK Python Bindings?
I am afraid to inform you that this SDK only supports the Tobii Pro range of Eye Trackers.
If you wish to develop an interactive (or gaming) application with the Tobii 4C, then we would refer you to:
The Tobii Interaction Library @ https://developer.tobii.com/product-integration/interaction-library/

Thanks for the reply. I was trying to add tobii_stream_engine.dll in the c# project but I have been facing an issue “please make sure that the file is accessible and that it is a valid assembly or com component”, Can anyone help me solving this issue.21/06/2021 at 12:35 #20564Grant [Tobii]Keymaster
Hi @meghanapuppala, we have created an extensive tutorial for the stream engine to help you get up and running using C#
please follow the steps closely and report back with exactly at which step the process is failing and kindly include your system specifications and IDE version, etc. Thanks.
