There will always be some difference between individuals and the accuracy of a calibration. However, the rating function is an approximation that doesn't tell the full story. It's possible that a four star is fairly close to a five since the cut off is a hard limit. The rating is done like this (values are in degrees of visual angle):

Code:: if (accuracy < 0.5) // perfect return 5; if (accuracy < 0.7) // moderate etc. return 4; if (accuracy < 1) return 3; if (accuracy < 1.5) return 2; return 1; // redo

So a 0.51 calibration would yield 4 stars but it's a still a good result

Try to check the accuracy with the mouse-redirect, is it constantly of any specific area of the screen?

The primary factors affecting the result is screen size and distance from the device (other than individual differences in pupil size, eye shape etc).

Sometimes I get 5, some days 4. Maybe to do with the room lighting at different times? I don't have any real knowledge of the difference.

[Resolved] 5 Stars Calibration

2014-09-10T22:03:40+02:00

Hi,

I was wondering if anyone was able to get a 5 stars calibration.
The best I was able to achieve is 4 stars.

Thanks

Christophe.
