Guest Calibration in 1.4.451

[NicholasC]

In the previous version TobiiEyeXSdk-DotNet-1.3.443 and C#, launching Guest Calibration triggers the usual 9-point calibration.

Using TobiiEyeXSdk-DotNet-1.4.451 , launching Guest Calibration triggers a 5-point calibration exercise instead. Subsequently, when I launch Recalibrate, it becomes the usual 9-point calibration.

Hence, may I ask if changing the guest calibration to the 5-point is intentional? and whether we could change it back to the usual 9-point calibration at the start?

thanks

Hi Nicholas,

The change to a 5-point calibration is intentional. The point is to have temporary calibrations done more quickly. This makes a huge difference if you want to demo your eye tracking application for a large number of people in a short time, and for that kind of situation the difference in accuracy and precision is not noticable.

Could you describe further why you find the 5-point calibration unsuitable for your use case?

Thank you Jenny for your reply. We have yet to test the 5-point calibration but we had noticed this sudden change from the 9-point to the 5-point calibration when we upgraded the software, hence we were wondering the reasons behind it.
