Interaction library calibration and comparison with stream engine

[Zeyu Mao]

Trying to use the interaction library to interfacing the eye tracker, succeed to run some cpp samples but then realize it needs a calibration. How to calibrate the eye tracker via the interaction library?

Also what is the difference between the interaction library and the stream engine?

Thank you in advance!

Hi @mzy2240, thanks for reaching out. All calibration is managed and performed using the Tobii Experience App system tray icon and is not accessible programmatically via the Tobii Interaction Library.

Custom Calibration is available with the Stream Engine API but only with the purchase of a special licence file.

The main differences between the Stream Engine and Interaction Library is the the Stream Engine is a lower level API with a lower memory footprint but requires a higher degree of programming experience to implement whilst the Interaction Library is designed for users to create interactive application as quickly as possible using .NET architecture.
