项目摘要

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.

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在大范围内的水平/垂直眼动数据。在原始研究中，只有水平和纵向震级校准应用于记录之前的数据。然而，数据的线性化有时会超出记录的实际范围。为了避免数据的非线性，我们提出了校准过程的新技术。为了校准数据，在数据采集之前进行了多次眼部扫描和短时间注视。实验结束后，利用定标过程中得到的线性方程中的参数对眼球水平和垂直数据点进行换算，为了进行大量的定标程序，我们引入了高性能的计算机图形系统，该系统通过GPIB接口与小型机系统接口。我们开发了200多种实用程序，使我们能够在CRT显示器上生成矢量。利用这些工具在屏幕上生成校准程序和视觉运动刺激，并结合多次校准程序进行各种数据采集，以检验校准方法是否令人满意。结果非常令人满意。并将该方法应用于EOG数据采集。同样，该应用程序足以将数据线性化。
