The assessment of color vision is crucial in both fundamental visual research and clinical diagnosis. However, existing tools for color vision assessment are limited by various factors. This study introduces a novel, efficient method for color vision assessment, which is based on a continuous motion tracking task and a Kalman filter model. The effectiveness of this new method was evaluated by assessing the color vision of both color-deficient observers and normal controls. The results from both a small sample (N = 29, Experiment 1) and a large sample (N = 171, Experiment 2) showed that color-deficient observers could be perfectly identified within 20 s using the tracking performance. We also compared the new method with a traditional psychophysical detection task to examine the consistency of perceptual noise estimation between the two methods, and the results showed a moderate correlation (Pearson's r = .59 ~ .64). The results also demonstrated that the new method could measure individuals' contrast response functions of both red-green and blue-yellow colors (e.g., the L-M and S-(L + M) axes in DKL color space) in just a few minutes, showing much higher efficiency than traditional methods. All the findings from this study indicate that the continuous motion tracking method is a promising tool for both rapid screening of color vision deficiencies and fundamental research on color vision.
色觉评估在基础视觉研究和临床诊断中都至关重要。然而,现有的色觉评估工具受到多种因素的限制。本研究引入了一种基于连续运动跟踪任务和卡尔曼滤波器模型的新型高效色觉评估方法。通过评估色觉缺陷观察者和正常对照者的色觉来评估这种新方法的有效性。小样本(N = 29,实验1)和大样本(N = 171,实验2)的结果均表明,使用跟踪性能可在20秒内完美识别出色觉缺陷观察者。我们还将新方法与传统心理物理学检测任务进行比较,以检验两种方法之间感知噪声估计的一致性,结果显示出中等相关性(皮尔逊r = 0.59 ~ 0.64)。结果还表明,新方法可以在几分钟内测量个体对红绿色和蓝黄色的对比度响应函数(例如,DKL颜色空间中的L - M和S -(L + M)轴),显示出比传统方法更高的效率。本研究的所有结果表明,连续运动跟踪方法是快速筛查色觉缺陷和进行色觉基础研究的一种有前途的工具。
