Paranoia 'reduced with virtual reality'

虚拟现实可减轻妄想症

Virtual reality has been used to help treat severe paranoia.

虚拟现实已被运于治疗严重的妄想症。

Patients who suffered persecutory delusions were encouraged to step into a computer-generated underground train carriage and a lift. The simulations allowed 30 patients to learn social situations they feared were actually safe.

研究员鼓励患有迫害妄想症的患者进入由计算机生成的地铁车厢和电梯模拟情境，让参与研究的30名病患了解他们害怕的社会情境实际上是安全的。

The research at Oxford University, published in the British Journal of Psychiatry, was funded by the Medical Research Council.

牛津大学进行的这项研究刊登在《英国精神病学期刊》上，该项研究由英国医学研究理事会资助。

Members of a group of patients were told to use their normal defensive behaviour, such as avoiding eye contact.

研究员告诉其中一组病患展示平常的防卫行为，例如避免眼神接触。

The rest of the patients were encouraged to lower their defences and try to learn they were safe by approaching computer characters (avatars) and standing toe-to-toe or staring at them.

其余的病患则被鼓励降低防卫心理，并走近计算机角色（化身），与这些角色近距离站立或直视他们，从而设法了解这些角色是安全的。

This group, who fully tested out their fears, showed the biggest reduction in their paranoid delusions. More than half of them no longer had severe paranoia at the end of the testing day.

全力测试抗拒恐惧的一组病患，迫害妄想症减轻幅度最大。测试当天结束时，多一半人不再有严重的妄想症。

The first group, who used their defences, also saw some reduction in the level of severe paranoia.

表现出防卫心态的第一组，严重妄想症也有一定种程度的降低。

The study was led by Prof Daniel Freeman, a clinical psychologist at Oxford University's Department of Psychiatry. He said, "At the heart of paranoia is the unfounded belief that people are under threat. With virtual reality we can help the person to re-learn that they are safe, and when they do that, the paranoia melts away."

该研究由牛津大学临床心理学家弗利曼（Daniel Freeman）教授主持。他说：“妄想症的核心是一种毫无根据的想法，认为人们都在遭受威胁。运用虚拟现实，我们可以帮助患者重新了解他们是安全的；当他们意识到这一点时，他们的妄想症便烟消云散了。

关于虚拟现实

虚拟现实是仿真技术的一个重要方向，是仿真技术与计算机图形学人机接口技术多媒体技术传感技术网络技术等多种技术的集合，是一门富有挑战性的交叉技术前沿学科和研究领域。虚拟现实技术(VR)主要包括模拟环境、感知、自然技能和传感设各等方面。模拟环境是由计算机生成的、实时动态的三维立体逼真图像。感知是指理想的VR应该具有一切人所具有的感知。除计算机图形技术所生成的视觉感知外，还有听觉、触觉、力觉、运动等感知，甚至还包括嗅觉和味觉等，也称为多感知。自然技能是指人的头部转动，眼睛、手势、或其他人体行为动作，由计算机来处理与参与者的动作相适应的数据，并对用户的输入作出实时响应，并分别反馈到用户的五官。
