<p>PROBLEM TO BE SOLVED: To provide a visual line detector to sufficiently cope with recalibration to be performed when input of a visual line becomes difficult by easy calibration. SOLUTION: This visual line detector is provided with a deviation correcting part 2C to perform calibration at either one point among plural standard points whose positions are known, to calculate an error due to motion of the head where an eyeball as a detecting object exists and t correct deviation of a detection result of visual line based on the calculated error when a recalibration instruction is received. Thus, since the deviation of the detection result of visual line is corrected by recalculating a correlation coefficient of a proper value according to the present situation simply by performing the recalibration of either one point among the plural standard points, the recalibration is performed in shorted time and more comfortable operability is provided to a user in comparison with the conventional manner.</p> |
