6种显示模式在虚拟训练中的对比研究

Objective To evaluate the display effects of four display devices, namely desktop, liquid crystal, projection and head-mounted, in virtual training. Methods Twelve subjects used virtual hoisting training as an experimental task and selected evaluation indicators such as objective performance, physiological characteristics and subjective experience to comprehensively compare the virtual training efficacy of six display modes of the four devices. Results The head-mounted display device had the best comprehensive evaluation in virtual training and scored the highest in the three indicators of objective performance, physiological characteristics and subjective immersion, but accompanied by the most severe symptoms of simulation sickness; the 3D display modes of liquid crystal and projection display devices had better evaluation results in virtual training than the 2D display modes; the screen size of the display device had no obvious effect on the efficacy of virtual training. Conclusion Among the four display devices, the head-mounted display device has the best display effect in virtual training.

目的评估桌面式、液晶式、投影式及头戴式4种显示设备在虚拟训练中的显示效果。方法12名受试者利用虚拟吊装训练作为实验任务,选取客观绩效、生理特征和主观体验等评估指标,综合对比4种设备共6种显示模式的虚拟训练效能。结果头戴式显示设备在虚拟训练中的综合评估最优,并且在客观绩效、生理特征、主观沉浸感这3项指标中得分最高,但伴随最严重的仿真病症状;液晶式和投影式显示设备的3D显示模式比2D显示模式在虚拟训练中的评估结果更优;显示设备的屏幕尺寸对于虚拟训练的效能影响作用不明显。结论4种显示设备中头戴式显示设备在虚拟训练中的显示效果最优。
