meet "InsufficientLicenseException: The license is insufficient. API error code"

Hi,

I am newbie of Tobii.
I am trying to run the calibration from unity on Windows 10 PC.

The device is Tobii EyeTracker 4C.
Unity version is 2019.2.17f1.
OS: Windows 10.

I can see the connect log and start log from console shown as the following:
#1 Connected Log
Connected to Eye Tracker: IS404-100109720872
UnityEngine.Debug:Log(Object)

#2 Start Log
Calibration started
UnityEngine.Debug:Log(Object)

Then the exception log was shown as the following:
InsufficientLicenseException: The license is insufficient. API error code: SeInsufficientLicense.

BTW, The software “Tobii Eye Tracking” can work and do calibration work.

Could somebody tell me how to solve this problem?

Thank you in advance.

Hi @chysun2000, and thanks for your query. In order to use the Tobii Pro SDK with the 4C Tracker, you will need to purchase a special analytical use licence to do so which you can read more about @ https://analyticaluse.tobii.com/

However, if your intention is simply to use Unity Engine with the 4C for interaction purposes, you can use the Tobii Unity For Desktop API which is designed to operate freely with this consumer-level eye tracker.

Please try it out @ https://developer.tobii.com/tobii-unity-sdk/ and let us know how you get on. Best Wishes.
