延迟率指用户的交互动作（如转头，移动，躲避）在虚拟环境中反馈出来并逞现在用户眼前这段时间的间隔。例如你蹲下那么在虚拟世界也会跟着蹲下，从你蹲下到虚拟世界蹲下的这个时间间隔就是延迟率，这个延迟率越低越好，行业标准是20ms以下，普遍厂商都能做到。影响延迟的因素有很多，例如定位延迟，显卡渲染延迟，如果是无线串流也会有网络因素等。
Medicolegal components of MR security: Discovering from your faults of Other people. With this section, quite a few real legal situations in which MR security-relevant medical malpractice was alleged will likely be reviewed and analyzed.

Defining and standardizing the assumed system algorithms for examining no matter if a client/system/implant/international object can properly bear MR imaging; reviewing the advantage-risk evaluation approach and setting up protocols and recommendations regarding tips on how to formalize the reward-danger ratio evaluation for each patient.
Additionally, it incorporates a review of a number of new recommendations and/or specifications for MR safety, such as These from the Joint Commission, ACR, and the tips with the Global consensus document entitled, “Suggested responsibilities for administration of MR basic safety”.
刷新率是指显示器每秒刷新画面的次数。常规最低是60Hz以上眼睛看起来才不会感觉到视觉延迟，达80Hz刷新频率就可完全消除图像闪烁和抖动感，眼睛也不会太容易疲劳。主流厂商刷新率保留在75Hz，90Hz，120Hz。

菲涅尔镜片又称螺纹透镜，镜面上刻录了大小不一的螺纹。上一代主流会采用菲涅尔镜片因为这样透镜更薄更轻，厚度很薄，通常只有几毫米，重量也大大减轻。使用螺纹镜片会有一定的牺牲，因为螺纹会影响曲率和光线聚焦。
非球面镜片比球面镜片更平、更薄、视物更逼真，这样观察虚拟世界不会发生边缘变形扭曲的现象。球面镜片在边缘视野范围会产生物象轻微的扭曲变形，这就是二者的最重要的区别。
