A study on the normalization procedure for eye movement recording.

该项目的目标是建立新开发的程序，以校准包括EOG方法在内的记录技术的广泛区域内的水平/垂直眼动数据。在原始研究中，在记录之前，只对数据进行了水平方向震级校准。然而，数据的线性化有时超出了记录的实际范围。为了避免数据的非线性，我们提出了校正过程的新技术。为了校准数据，在数据采集之前进行多次眼睛扫描和短时间注视。实验结束后，利用标定周期得到的线性方程参数对垂直、水平数据点进行转换。为了进行大量的各种校准程序，我们介绍了由GPIB与小型计算机系统接口的高性能计算机图形系统。开发了二百多种使我们能够在CRT显示器上生成矢量的实用程序。使用这些工具在屏幕上生成校准程序和视觉运动刺激。为了检验校准方法是否令人满意，我们进行了各种数据采集，并进行了多次校准程序。结果非常令人满意。并在EOG数据采集中进行了验证。同样，应用程序足以线性化数据。

The project had a aim that would establish the newly developed procedure to calibrate the horizontal/vertical eye movement data in a broad wide area fo the recording technique including EOG method. On a primitive study, only the horizontal andertical magnitude calibration has been applied to the data prior to the recordings. However the linearization for the data is sometimes exceeds the practical range on recordings. To avoid the un-linearity of the data, we proposed the new technique of the calibration procedure. To calibrate the data, multiple eye scanning and short fixations on them was performed prior to the data aquisition. After the experiments, eyert horizontal and vertical data point were converted with using the parameters from the linear equation which was obtained from the calibration periods.To carry on the great amount of the kinds of the calibration procedure, we introduced the high performance computer graphic system interfaced by GPIB with minicomputer system. Over two hundred kinds of the utility which enables us the generation of the vector on CRT display were developed. Calibration procedure and visual moving stimuli were generated on the screen with using these utilities.To test wheather the calibration method is satisfactory or not, we carried on various kind of the data acquisitions coupled with the multiple calibration procedure. The result was extremely satisfactory. The methods were tested to the EOG data aquisition too. Again the application was enough to linearize the data.
