提出了当受试者凝视固定目标时眼球运动的小波分析。这使我们能够从原始数据中获得眼球运动的低噪声波形。数据的时间导数,i。例如,速度和加速度,可以使用这种方法轻松获得。将结果与使用 FIR 滤波器平滑微型眼球运动波形的方法获得的结果进行比较。讨论了三种应用:使用混沌吸引子的眼球运动表示、眼球运动加速度的矢量表示以及估计微型眼球运动加速度的微小偏度的统计分析。还讨论了使用小波分析来减少眨眼成分。这些应用程序可用于评估新型虚拟和立体显示器的图像质量。
Wavelet analysis of eye movements when subjects gaze at a fixed target is proposed. This enables us to get a low-noise waveform of eye movement from raw data. Time derivatives of the data, i. e., velocity and acceleration, can be easily obtained using this method. The results are compared with the results obtained by a method that smooths the waveform of miniature eye movement using an FIR filter. Three applications are discussed : a representation of eye movement using chaotic attractor, a vector representation of acceleration of eye movement, and a statistical analysis to estimate minute skewness of miniature eye movement acceleration. The decrease of the blink component using wavelet analysis is also discussed. These applications can be used to evaluate the picture quality of new virtual and stereoscopic displays.
