虚拟现实的4种迷人应用

Virtual Reality （VR） headsets are now being used in many industries as a way of training people or providing a new way to experience things. Here are four ways in which virtual-reality technology is being used.

目前，虚拟现实（VR）头显设备广泛应用于多种行业，其主要用于训练或提供一种新的体验方式。以下是VR技术的4种应用。

Theater audiences can already enjoy 3D movies， but with apps like Oculus Cinema， users can be even more deeply immersed in their movie experiences. They can watch movies on a huge virtual screen， something like their own personal theater， or even watch as if they were inside the movie itself， surrounded by the imagery and sound effects. And if you are a sports fan， the virtual reality platform company LiveLike VR has built a virtual stadium so you can have the thrill of game day experiences with your friends， right from the comfort of your couch.

電影观众已经能体验3D电影带来的乐趣，但如果再配合Oculus Cinema 这类应用，使用者将拥有更深入的沉浸式观影体验。观众可以通过VR头显设备投射出的巨大虚拟屏幕观看影片，好似拥有一个个人专享的影院一般，画面、声效萦绕，仿佛身临其境。如果你是体育迷，你和朋友舒服地窝在沙发里也能体验到比赛现场的刺激;而这只需要通过虚拟现实平台公司LiveLike VR所创建的虚拟球场应用便可实现。

The health care industry has been a big adopter of virtual reality tech， with some institutions using the computer-generated images for diagnosis and treatment. Virtual reality simulations， such as those created by software companies Surgical Theater and Conquer Mobile， use actual diagnostic images from CAT scans or ultrasounds to construct 3D models of a patients anatomy. The virtual models help both new and experienced surgeons determine the safest and most efficient way to locate tumors， place surgical incisions or practice difficult procedures ahead of time.

Beyond surgery， virtual reality could also serve as a cost-effective and engaging tool for rehabilitation. Stroke and brain injury victims across Europe can now use an immersive virtual-reality therapy created by MindMaze to regain motor and cognitive function faster than with traditional physical therapy， according to the company.

医疗卫生一直以来都是VR技术的主要应用领域，一些机构利用电脑生成的图像进行诊断和治疗。Surgical Theater 和 Conquer Mobile 等软件公司研发的VR仿真模拟软件使用CAT扫描或者超声波诊断图像来生成患者身体构造的3D模型。虚拟模型可以帮助新手或有经验的外科医生找到最安全、最有效的方法来定位肿瘤和手术切口位置，或是提前练习有操作难度的手术流程。

除了应用于手术，VR同时也是一种高性价比康复工具，对病患颇具吸引力。MindMaze公司称，在欧洲，中风及脑损伤患者现在可以使用其研发的沉浸式VR疗法来恢复运动和认知能力，使用这种疗法的恢复速度要比传统的物理治疗更快。

Scientists at NASA have a tough mission： to search for life on other planets. Thats why they look to cutting-edge virtual reality technology to control robots on Mars and to provide astronauts with a way to de-stress. At NASAs Jet Propulsion Laboratory， researchers connected the Oculus Rift with motion-sensing equipment from the Kinect 2 sensor and Xbox One game console to control a robotic arm with the operators gestures. The setup could one day be used to control rovers or other instruments millions of miles away， according to NASA. By adding a Virtuix Omni treadmill to the setup， researchers were also able to simulate a walk on Mars to prepare astronauts for a potential human landing.

美国航空航天局的科学家面临一个艰巨的任务，即搜寻其他星球上的生命。因此，他们希望用前沿的VR技术控制火星上的机器人，并为宇航员提供一种解压方式。在美国航空航天局的喷气推进实验室，研究人员把Oculus Rift和Kinect 2 传感器上的运动传感设备以及Xbox One游戏主机连接起来，利用操作者的手势控制机械臂。美国航空航天局称，这套设备未来可能被用来控制巡视器或其他几百万英里以外的设备。如果把Virtuix Omni 跑步机与这套设备连接，研究者也可以模拟在火星表面行走，为未来人类登陆火星做准备。

Virtual reality can also act as a therapeutic tool for those who experience debilitating stress， including post-traumatic stress disorder （PTSD）， and panic disorders or phobias， researchers say. Virtual reality tech could provide a safe environment for patients to come in contact with the things they fear， while remaining in a safe， controlled environment.

研究者稱，VR技术也可以作为一些严重压力疾病的治疗工具，比如创伤后应激障碍，以及惊恐性障碍或恐惧症。VR技术可以给患者提供一个安全可控的环境，让他们接触自己恐惧的事物。
