| 目的 将本研究开发的基于虚拟现实（VR）的工作记忆测试系统应用于认知康复的执行功能评估，并与传统E-prime工作记忆测试系统进行比较，以期为临床提供一种新的工作记忆测试工具。 方法 邀请2名资历较深的康复治疗师作为主试，招募30例健康受试者，对比传统工作记忆测试系统和基于VR的工作记忆测试系统在完成2-back任务时的平均反应时和正确率，并采用通过系统可用性量表（SUS）、模拟器不适感量表（SSQ）和半结构式访谈评估基于VR的工作记忆测试系统的可用性和用户体验。 结果 30例受试者VR工作记忆测试的平均反应时和正确率与传统工作记忆测试比较，差异均无统计学意义（P>0.05）。VR工作记忆测试的SUS评分为（76.0±9.2）分，处于“Good-Excellent”水平；其SSQ评分为（4.80±3.16）分，未出现显著不适感；半结构式访谈评估显示，VR工作记忆测试系统易操作、沉浸感强，在认知康复的执行功能评估中适用。 结论 基于VR的工作记忆测试系统具有较高的可用性和用户接受度，可为受试者实现沉浸式的个性化测试场景，可作为工作记忆的测试工具。 |

| Objective To compare the effectiveness of a new virtual reality (VR) working memory test system with that of the traditional E-prime working memory test system in terms of evaluating executive function in cognitive rehabilitation. Methods Two experienced rehabilitation therapists tested 30 healthy subjects. The average reaction time and accuracy of the traditional and the VR-based working memory test systems in completing the 2-back task were compared. The usability and user experience of the VR-based working memory test system were also evaluated using the system usability scale (SUS), a simulator discomfort scale (SSQ) and semi-structured interviews. Results There was no significant difference in the average reaction time and accuracy of the 30 subjects between the two different tests. The SUS score of the VR working memory test was at the "Good-Excellent" level, and the SSQ scores demonstrated that no significant discomfort was observed. In the interviews the VR working memory test system was described as easy to operate and as having a strong sense of immersion. Conclusions The VR-based working memory test system has good usability and user acceptance, and can provide subjects with an immersive and persona-lized test scenario. Therefore, it can be used as a tool for testing working memory. |
