中文摘要:

      目的 了解头戴式虚拟现实设备的热特性，以及用户的主观热舒适感受。方法 让被试者使用头戴设备45 min，过程中采用温度记录器记录数据，最后用主观量表获取热舒适评分。获得的数据用SPSS进行方差分析，并结合设备的物理属性进一步进行主观热舒适影响因素分析。结果 三款头戴设备的平均微环境温度在使用时间内共上升了8.11 ℃，主观热不适程度随使用时间的增加而增强。数据统计结果表明，三款设备间的微环境温度和主观热舒适数据差异显著（p<0.05）。结论 头戴式虚拟现实设备在使用时间内的微环境温度变化会对用户造成“轻微不适”的热感受，在提升产品热舒适方面可以从显示器的发热性和目镜的散热性入手。用户更青睐透气性强、且对面部相对不造成压力的S款设计。

英文摘要:

      The work aims to understand the thermal characteristics of head-mounted display and users’ subjective thermal comfort. Subjects were asked to wear the headset for 45 minutes. During the process, a temperature recorder was used to record the data. Finally, a subjective scale was used to obtain the thermal comfort score. The obtained data were analyzed by SPSS for variance analysis, and the factors influencing subjective thermal comfort were further analyzed based on the physical attributes of the equipment. The average microclimate temperature of the three head-mounted displays increased by 8.11 ℃ during the use time, and the subjective thermal discomfort increased with the use time. The statistical results showed that the microclimate temperature and subjective thermal comfort data were significantly different among the three devices (p<0.05). The microclimate temperature change of the head-mounted display during the use time will cause “slight discomfort” to the user. In order to improve the thermal comfort of the product, it can start with the thermal performance of the display and the heat dissipation of the eyepiece. Users prefer the S design with strong air permeability and relatively no pressure on the face.
