虚拟现实（VR）是一种新兴的腹腔镜技能培训的新模式，然而，大多数模拟器缺乏现实的触觉反馈。增强现实（AR）是一种新的腹腔镜模拟系统，提供了物理对象和VR模拟相结合。腹腔镜器械在使用视频跟踪的同时在组织或物体上的混合人体模型内使用。本研究旨在评估AR和VR腹腔镜模拟在真实性、触觉反馈和教学价值方面的差异。本研究中使用了ProMIS AR和LapSim VR模拟器。参与者在两个模拟器上执行了一项基本技能任务和一项基本技能任务，之后他们填写了一份关于他们的人口统计数据的问卷，并在5分制的李克特量表上对两个模拟器进行了评分。参与者根据他们的经验分为3组：专家，中间和新手。采用配对t检验计算显著性差异。所有组的普遍共识是，ProMIS AR腹腔镜模拟器在基本技能任务中比LapSim VR腹腔镜模拟器更逼真（平均值分别为4.22和4.22）。2.18，P < 0.000）以及重复任务（平均4.15，P < 0.000）。1.85，P < 0.000）。ProMIS被认为具有更好的触觉反馈（平均3.92，1.92，P < 0.000），并且对于培训外科住院医师更有用（平均值分别为4.51。2.94，P < 0.000）。与VR模拟器相比，AR腹腔镜模拟器被所有参与者视为所有测试功能的腹腔镜技能培训的更好模拟器。
Virtual reality (VR) is an emerging new modality for laparoscopic skills training; however, most simulators lack realistic haptic feedback. Augmented reality (AR) is a new laparoscopic simulation system offering a combination of physical objects and VR simulation. Laparoscopic instruments are used within an hybrid mannequin on tissue or objects while using video tracking. This study was designed to assess the difference in realism, haptic feedback, and didactic value between AR and VR laparoscopic simulation. The ProMIS AR and LapSim VR simulators were used in this study. The participants performed a basic skills task and a suturing task on both simulators, after which they filled out a questionnaire about their demographics and their opinion of both simulators scored on a 5-point Likert scale. The participants were allotted to 3 groups depending on their experience: experts, intermediates and novices. Significant differences were calculated with the paired t-test. There was general consensus in all groups that the ProMIS AR laparoscopic simulator is more realistic than the LapSim VR laparoscopic simulator in both the basic skills task (mean 4.22 resp. 2.18, P < 0.000) as well as the suturing task (mean 4.15 resp. 1.85, P < 0.000). The ProMIS is regarded as having better haptic feedback (mean 3.92 resp. 1.92, P < 0.000) and as being more useful for training surgical residents (mean 4.51 resp. 2.94, P < 0.000). In comparison with the VR simulator, the AR laparoscopic simulator was regarded by all participants as a better simulator for laparoscopic skills training on all tested features.
