Abstract
A calibrating system is provided, and a reference result calculating device of the calibrating system generates an eye position and a reference line-of-sight angle at each historical time point. Furthermore, a filtering processing device performs filtering process on a first predicted line-of-sight angle generated by a line-of-sight predicting device according to a first image of the eye, so as to obtain a second predicted line-of-sight angle at the historical time points. e. A compensation value calculating device obtains a bias value according to the second predicted line-of-sight angle and the reference line-of-sight angle. A configuration managing device updates the second predicted line-of-sight angles and bias values in a configuration file. A line-of-sight correcting device calculates an average bias value of the second predicted line-of-sight angle according to the configuration file, and compensates a future predicted line-of-sight angle according to the average bias value.
