Abstract

OBJECTIVE:

To present a quick algorithm to automatically analyze the raw data acquired by a photo-oculography (POG) system.

METHODS:

We developed a simple algorithm for POG data analysis based on an extrapolation of missing values due to blinking and on exclusion of outliers using the robust mean and standard deviation.

RESULTS:

POG curves of 4 children aged between 1.5 and 7 years are shown before and after automatic analysis. After applying our algorithm, the curves are much smoother.

CONCLUSION:

Our algorithm allows a quick data analysis and will help to better interpret and analyze POG data.
