A novel gaze tracking method that requires only one calibration marker for personal calibration is proposed. In general, personal calibration is known to be a troublesome task, which requires the user looks at nine to twenty calibration markers in succession. Unlike traditional methods, the proposed method drastically reduces the cost of personal calibration. This method, which is called the One-Point Calibration method (OPC method), requires only one calibration marker for the personal calibration. While the user looks at the calibration marker, the difference between the user's eyeball shape and the eyeball model used in calculating the user's gaze direction is estimated, and residual error is compensated by the parameters derived by the calibration.
