基于不同脑力负荷和任务类型的信息颜色编码

The Color Coding of Information Based on Different Mental Workload and Task Type

通过分析飞行员驾驶战斗机过程中的任务特征,开发了一个包含四个显示界面的交互仿真模型,每个显示界面对应不同类型的任务。通过改变任务信息显示频率来控制脑力负荷,以正确反应率和反应时间作为绩效指标,评价和分析被试对不同颜色编码信息的辨识情况,为信息显示界面的工效学设计提供科学依据。实验结果表明:脑力负荷对不同颜色编码的信息辨识情况影响不尽相同;对于不同类型的任务,信息颜色编码方式不尽相同;颜色编码方式对信息辨识具有显著影响,需根据不同的脑力负荷和任务类型进行选择。

Through analyzing task characteristics in the process of driving aircrafte by pilot, an interactive simulation model was developed, which contains four display interfaces corresponding to different types of the tasks. The subject＇ s identification situation to the different color codings was evaluated and analyzed by the experiment, in which mental workload is controlled by changing display frequency of task information and correct response rate and reaction time are regarded as performance indicators, to provide a scientific basis for designing ergonomics of information display interface. The experimented results show that the mental workload has different influences on information identification when the color coding schemes are different; the information color coding has different influence when the task types are different; the matched background-target colors have significant effect on information identification, which are selected according to the different mental workloads and task types.
