I chosed according to this, but my version is SRanipal_GazeRaySample.cs.Using this i could get data in 90HZ,if i use SRanipal_GazeRaySample_v2.cs,i just got data in 50HZ.Why does it lead to such a structure? Thanks in advance!

've learned about eye movement data from the SDK, but I don't know anything about getting these data. I hope you can help me. Thank you very much! Here's some code for eye movement data： public struct SingleEyeData { /** The bits containing all validity for this frame.*/ public System.UInt64 eye_data_validata_bit_mask; /** The point in the eye from which the gaze ray originates in meter miles.(right-handed coordinate system)*/ public Vector3 gaze_origin_mm; /** The normalized gaze direction of the eye in [0,1].(right-handed coordinate system)*/ public Vector3 gaze_direction_normalized; /** The diameter of the pupil in meter miles*/ public float pupil_diameter_mm; /** A value representing how open the eye is.*/ public float eye_openness; /** The normalized position of a pupil in [0,1]*/ public Vector2 pupil_position_in_sensor_area; public bool GetValidity(SingleEyeDataValidity validity) { return (eye_data_validata_bit_mask & (ulong)(1 << (int)validity)) > 0; } } @Corvus

Hello @Corvus, How to get eye movement data through the SDK?I use the HTC Pro instrument. In the SDK, i found some eye movement data code, but i want to know how to extract it.thank you so much！ public struct SingleEyeData { /** The bits containing all validity for this frame.*/ public System.UInt64 eye_data_validata_bit_mask; /** The point in the eye from which the gaze ray originates in meter miles.(right-handed coordinate system)*/ public Vector3 gaze_origin_mm; /** The normalized gaze direction of the eye in [0,1].(right-handed coordinate system)*/ public Vector3 gaze_direction_normalized; /** The diameter of the pupil in meter miles*/ public float pupil_diameter_mm; /** A value representing how open the eye is.*/ public float eye_openness; /** The normalized position of a pupil in [0,1]*/ public Vector2 pupil_position_in_sensor_area; public bool GetValidity(SingleEyeDataValidity validity) { return (eye_data_validata_bit_mask & (ulong)(1 << (int)validity)) > 0; } }
