Problem using tobii 4C python example code

[Fred]

Hi,
I just bought a tobii 4C yesterday. I download core software from https://www.tobii.com/getstarted and it works like charm. But when I follow the guide in http://developer.tobiipro.com/python/python-step-by-step-guide.html and try to run the most simple example code, I went into some problem:

python could find my device and give the information right. But it just won’t call the callback function, which means no eye information data was printed.

Could help me out?

Thanks,
Fred

Hi @yxhao and thanks for your query. The Python bindings you refer to are part of the Tobii Pro SDK which by default will not operate in conjunction with the Tobii 4C Consumer level eye tracker.

In order to get the 4C to work with the Pro SDK you need to purchase a special unlock file for which you can obtain a quote by email the SDK Licencing Sales department directly at [email protected]

Alternatively, if you are comfortable with .NET, you may freely use the Tobii Core SDK which operates without restriction on the 4C.

To get started, checkout our guide @ https://developer.tobii.com/consumer-eye-trackers/core-sdk/getting-started/

with sample applications available @ https://github.com/Tobii/CoreSDK

Any further questions, please don’t hesitate to get in touch again.
