Pro Eye Tracker Calibration Data

[jc10487]

Hi all,

Is there anyway to access the calibration data? Thanks

@jc10487 What access are you interested in? The eye tracking SDK can provide a validity status and flag for if calibration is needed.

@Corvus is it possible to acquire the fixation positions and eye positions from calibration?

@jc10487 Currently there is no official access to further calibration data beyond what I mentioned in the last post. The gaze direction and eye position data is available after calibration if that is the information you need.

@Corvus That's unfortunate. Thank you for your help, though.

Hi there, how often should I do calibration? Thanks

[Corvus]

@adamsmitt For best accuracy (for example when doing research/training) ideally calibration would be done every time the user puts on the HMD (since every time it is placed and adjusted it can be a slightly different position). For other use cases (gaming or development) where eye tracking accuracy is less necessary I rarely have to calibrate unless switching users.
