Calibration Quality

[warbyrd]

How exactly is the 5-star ranking in the EyeTribeUI defined - is it just the average error? Or does it some more fancy calculation to define the quality?

Code: Select all

            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

I wrote a custom calibration procedure (in JavaScript) and could not get above 2 stars - for all those who have a similar problem:

i solved that issue, by giving the user time to rest his eyes for ~500ms before starting to collect data (sending 'pointstart') in every point. and not - like before - jump from one point to another - that gave me

huge errors - like 15 degrees and such. - this could be mentioned in the calibration api to help former developers, maybe.

now i easily get 5 stars with my own procedure and implemented your star-ranking, too - thank you for pointing that out to me.
