Hi @gizmowww,
Yes, I can confirm you can implement custom calibration such as number of calibration points, speed and calibration point shape with the Tobii Stream Engine SDK.
However, to be able to create custom calibration applications, you must first request a special licence to do so which you can
obtain by getting in touch directly with the SDK licencing team – [email protected]
Please bear in mind however, that whilst possible we do not actively provide support at this time in implementing custom calibration.
