皮电测量在虚拟仿真驾驶座舱实验教学中的应用

虚拟仿真驾驶座舱评测是汽车人机交互设计教学中的重要一环。依托汽车交互实验室的研究背景和条件,在主观和行为测量基础上,将皮电测量引入研究生课程,在整个设计流程中发挥学生主观能动性,自主展开命题、设计调研、实验设计和可用性评测。以评测车载多屏互动音乐系统为例,学生在驾驶仿真台架上完成两种设计方案实验评测。实验表明,使用中控触屏的皮电高于使用方向盘按键,即中控触屏心理负荷更低,结果与中控触屏系统可用性量表分值更高且任务用时更短趋势一致,说明皮电测量与主观和行为测量结合能有效评测汽车人机交互界面设计的可用性。学生通过课程学习掌握皮电测量评测方法,为自主展开研究奠定基础。

Application of EDA Measurement in Driving Simulator Experiment Teaching

Virtual simulation evaluation is an important part of iteration in the teaching of automobile human-computer interaction design.Relying on the research background and conditions of the UXLAB,the EDA measurement is combined with subjective and behavioral measurement in the graduate course.In the whole design process,we give full play to students'subjective initiative,students can independently carry out propositions,design research,experimental design and usability evaluation.Taking the evaluation of the car music system as an example,the students completed the experimental evaluation of two design schemes on the driving simulator.The experiment shows that the EDA uses the central control touch screen to be higher than that of using the steering wheel keys,that is,the psychological load of the central control touch screen is lower.The results are consistent with the trend that the availability scale score of the central control touch screen system is higher and the task time is shorter.It shows that the combination of EDA measurement and subjective and behavioral measurement can effectively evaluate the availability of automobile human-computer interface design.Students master the methods of EDA measurement and evaluation through the course,which lays a foundation for independent research.
