you call the addCalibrationPoint function. This instructs the eye tracker to collect data for the given point. There is a small delay (about 500 ms if I remember right) before the actual recording starts. The operation finishes when enough data has been collected, or after a timeout.
Ah, that’s the information I was missing, thanks. It would probably be a good addition to the dev guide. Since that function was always called AFTER displaying the calibration targets in the code samples, I was under the assumption that previously collected data was used and no recording of new data was triggered.
Am I correct to assume that addCalibrationpPoint is a blocking function so that I can do whatever I want, as soon as control is returned to the calling function?
