What does 'dt' in the eye tracking data represent? Also, Is there a way to get the fixations from eye tracking data provided from Hololens2?

Where did your data from? If you are using MRTK & Unity to develop MR App, we're usually using CoreServices.InputSystem.EyeGazeProvider to access eye-tracking data: Accessing eye tracking data in your Unity script. Could you provide your eye-tracking data sample and the steps to reproduce it?
@Hernando Ren
Thank you for replying. My real question is this, can the timestamped duration in the eye tracking data be used to calculate fixations?
If so, how? Do we directly extract the duration as fixation?
Did your "fixation" mean Eye-gaze and dwell? If so, please refer to the implementation of DwellSelection method to know how to start a timer to detect whether the user is intentionally staring at the target.
