摘要：

Exact calibration in real time is critical for gaze control systems. Five different calibration techniques were investigated: a standard calibration using linear and second order models (9 and 25 points); 2D mapping with interpolation: a mapping with developed model, describing eye image Formation process. Results show that there is no significant difference between polynomial calibration method and a mapping with developed model. Calibration using model has an advantage because there is no need to follow a whole calibration points each time. The point of gaze accuracy achieved during experiments is less than 1 degree.
