Hi @mixware and thanks for your query. I am afraid we have currently no official support for Delphi, but perhaps the best bet if for you to try the Tobii Stream Engine API C++ bindings available @ https://developer.tobii.com/consumer-eye-trackers/stream-engine/getting-started/
and try to combine this with C++ builder which should also be compatible with Delphi.
Please try this out and let us know how you get on. Best Wishes.
