【摘要】：通过主、客观实验相结合的方法对面向视觉显示终端(VDT)的信息显示界面视觉舒适度的客观描述模型进行研究。以不同色彩组合的仪表界面为测试对象,采集被试者的脑电信号,得到P100和P300幅值、潜伏期以及各频段下的脑波能量P,并对表盘界面进行舒适度主观评分。利用多项式拟合回归,建立视觉舒适度(VC)与FP4和β波能量Pβ之间的数学模型。研究结果表明:通过相关性分析,得到视觉舒适度分别与顶叶P4处的P300幅值FP4(相关系数为0.644,显著性ρ0.05)、β波能量Pβ(相关系数为0.850,ρ0.005)及比值P(α+θ)/β(相关系数为-0.872,ρ0.005)均显著相关。模型显示视觉舒适度与FP4呈正向线性关系,与Pβ呈二次抛物线关系,二者的交互作用与视觉舒适度呈负相关关系。利用该数学模型对视觉舒适度进行客观描述是可行的,同时该模型可用于对VDT视觉显示界面视觉舒适度的评价。
[Abstract]:The objective description model of visual comfort for visual display terminal (VDT) is studied by combining subjective and objective experiments. Taking the instrument interface with different color combinations as the test object, the EEG signals of the subjects were collected, and the P100 and P300 amplitudes, the latency period and the brain wave energy under various frequency bands were obtained, and the subjective score of the comfort degree of the dial interface was evaluated. The mathematical model between visual comfort (VC), FP4 and 尾 wave energy P 尾 was established by polynomial fitting regression. The results showed that visual comfort was significantly correlated with P300 amplitude FP4 (correlation coefficient 0.644, significant 蟻 0.05), 尾 wave energy P 尾 (correlation coefficient 0.850, 蟻 0.005) and ratio P (伪胃) / 尾 (correlation coefficient -0.872, 蟻 0.005). The model showed a positive linear relationship between visual comfort and FP4, a quadratic parabola relationship with P 尾, and a negative correlation between visual comfort and visual comfort. It is feasible to use the mathematical model to describe the visual comfort, and the model can be used to evaluate the visual comfort of VDT visual display interface.
