10年前我记得汤姆克鲁斯演过一部电影叫《少数派报告》，讲述的是未来的刑侦机构可以预知刑事犯罪的时间和地点，并在悲剧真正发生前瞬间将被害人救出，并将罪犯绳之以法。在此，故事情节我不想提及，大片随时都可以去网上看。我只想针对其中办案人员通过手势驱动计算机系统的运作从而产生虚拟现实场景，作进一步的展开，还是那句话，我们电梯人只谈电梯。
虚拟现实技术也被称作VR，是Virtual Reality的缩写，如果您看到的是VRP，那就是Virtual Reality Platform的缩写，即虚拟现实平台。目前我国电梯领域的专业软件公司运用VR技术已经开始在国际电梯安装维保领域中展露头角。戴上虚拟现实智能眼镜，手握控制手柄后你就是一个穿着桔色工作服的虚拟电梯检修工了。
By wearing virtual reality glasses or helmet, and 2 wireless remote stickers, now you are soon becoming an elevator installer in a world of virtual reality.
通过眼镜你就会看到虚拟井道安装场景，控制手柄就是你的手，通过手柄操作可以完成抓取、移动、定位、按压等动作。如下是轿厢架吊装安装的虚拟场景，通过手势握持动作可以把持吊装铁链将上梁移动到安装位置。
Through the glasses you will see the entirely real situation what you’d ever seen in the hoist-way. You can use the stickers as your hands to grab, to move and to press work-pieces until they kept their place in position. Below is about the process of crosshead lifting and mounting.
通过手势握持动作抓住导靴，系统会自动提示你安装的位置和在导靴板上的方向定位，如下图黄色部分所示：
Below is the process of grabbing guide shoes and adjust its direction for correct mounting, which has been high-lightened in yellow.
当然通过系统的智能解析模块，也可以自动判断出你身体部位的位置，比如在检查门机光幕的响应精度过程中，可以在关门时把手放到门缝中，感受门板停住并弹开的反应，系统会自动记录光幕的响应时间并给调试员做出引导。
By the function of embedded intelligent analysis module, the system will know wher your body exactly is. The best example for this is to try extending your hand in the middle of two car door panels as they are closing, and see its sensibility. The module will automatically record the reaction time of light curtain probing the obstacle and bouncing to opposite direction.
培训模拟不仅可以是单人模式，也可以有多人联机模式，比如一人在在底坑检查限速器张紧装置的同时另一个人检查电气开关的安全性是否符合要求。
The training courses can be set to the mode of multiple installers by networking. For example one guy is inspecting tension device of over-speed governor meanwhile allow the other checking the electrical switches in pit.
在具体某个科目的检修环节中，系统还会自动提供引导人员如何进入，比如轿顶检修的基本操作，下图方框中的脚印图标显示的是踩踏点，引导如何正确安全进入到轿厢顶部。
During the course of car roof inspection, the system will guide the installer enter by following the footprint marked on the surface of car roof, which means you can step onto it safely.
企业可以根据培训需求制定针对本企业的培训科目，带教老师也可以录制培训知识点的具体操作过程，作为企业标准安装培训视频教程，还可以针对学员科目知识点考试结果予以评分，如下图所示。
The training department of elevator company can figure out detail subjects according to their own requirements. This also allows the trainers to create a series of preliminary correct operation activities with proper sequence as standard and assess students performance when in exam.
