显示界面多维视觉编码综合评价模型

为预测与评估多维视觉编码对飞行员信息辨识的影响,在大量已有单维视觉编码研究的基础上,采用元分析和综合绩效法对显示界面上的多维视觉编码进行归一量化,结合G1法所确定的权重系数并运用模糊加权平均算子,建立了一种新的显示界面多维视觉编码综合评价数学模型.为了验证模型的效度,对波音和空客界面进行了综合评价,据此设计出优化界面,采用22名被试在不同显示界面下开展仪表监视实验,并采用了主观评价法、任务绩效评价法和生理评价法(包括眼动追踪测量和心电图时域指标测量)3种方法记录实验数据.综合测评结果表明:模型的理论预测值与多种实验方法测量结果显著相关,优化界面更利于被试完成信息辨识任务.显示界面多维视觉编码综合评价模型的提出对指导飞机驾驶舱显示界面的设计具有一定的参考价值.

Comprehensive evaluation model of multidimensional visual coding on display interface

To predict and evaluate the effects of multidimensional visual coding on pilot's information identification, a new comprehensive evaluation mathematical model of multidimensional visual coding on display interface, which adopted meta-analyses and integrated performance values (IPVs) for the unitary quantification of multidimensional visual coding, and combined the weight coefficient determined by G1 method with fuzzy weighted average operator, was proposed based on a large number of existing research about single-dimensional visual coding. In order to verify the validity of the model, interfaces of Boeing and Airbus were comprehensively evaluated, based on which optimized interface was designed. 22 subjects performed an instrument supervision task under different display interface. Subjective evaluation, performance measure and physiological assessment, including eye-movement tracking and electrocardiogram (ECG) time domain index, were introduced to record the experimental data. The integrated experimental results reveal that theoretical predictions calculated by the model is significantly correlated with the practical experimental results, and the optimized interface provides performance advantages, especially for more difficult tasks. This comprehensive evaluation model of multidimensional visual coding on display interface will provide a reference for the optimized design of aircraft cockpit display interface.
