center;">当我们迈进这个新天地时必须小心，要知道，眼见的不一定为实。</div><div> </div><div>人们常说，你不能完全相信网上看到的事情，沉浸式技术的出现（VR /AR ）更是让这句话成了铁板钉钉的事实。<span style="line-height: 1.8em;">麻省理工学院的一个项目正在寻找这些问题的答案。这项研究把人们放进自动驾驶汽车的后座，并迫使他们在生死选择的情况下做出道德决定。</span><span style="line-height: 1.8em;">尽管这些沉浸式技术的性能尚未被发掘完全，但我们已经意识到了它们操控人类思想的潜能。</span></div><div><span style="line-height: 1.8em;"><br></span></div><div>你可能觉得自己不会轻易上当，但如果它们技巧娴熟微妙根本无法被发觉呢？的确，一旦置身于VR世界，你可能什么都不知道就已经被“熏陶”了。</div><div><br></div><div>在视频会议中，视频数据所记录的即是原像，但沉浸式技术与之不同，它只是选择性发送信息，并不会传递所有的图像内容。<span style="line-height: 1.8em;">这在多玩家游戏中往往如此，游戏服务器只把坐标和其他信息发到你的电脑上，然后你的电脑再借此描绘出一张完整的图像。</span><span style="line-height: 1.8em;">交互性VR的性质也与此类似。在很多情况下，远程电脑和你的电脑之间所共享的信息很少，实际视觉场面都是各自构建的。</span><span style="line-height: 1.8em;">也就是说，你在你的终端所看到的和在其他终端看到的不尽相同。如果你用VR聊天，那么你的面部特征、表情、手势、肢体表现和其他特征都会被<a href="http://opticaldesign.oecr.com" target="_blank" class="relatedlink">软件</a>所改变，而你对此并不知情。</span></div><div><span style="line-height: 1.8em;"><br></span></div><div style="text-align: left;"><span style="line-height: 1.8em;">像你又像我</span></div><div style="text-align: left;"><span style="line-height: 1.8em;"><br></span></div><div>往好处想，VR在很多领域都所帮助。例如，研究表明，眼神交流会使学生更专注，但在大班教学中老师根本无法与所有学生对视。<span style="line-height: 1.8em;">然而，有了VR，我们就可以将此软件编程为——让老师看上去正在与所有学生同时进行眼神交流。因此，现实中的不可能在虚拟中得以实现。</span><span style="line-height: 1.8em;">但总有人会利用这种手段去做一些不法的事情。如果使用者不是老师，而是政治家或说客，他们说了一些更具争议性的事情，而眼神交流意味着更具说服力，那怎么办？而这只是个开头。</span></div><div><span style="line-height: 1.8em;"><br></span></div><div>研究表明，大家在虚拟世界中的形象能影响现实世界中的我们 。<span style="line-height: 1.8em;">这与某些其他技术相辅相成，那些技术早已被用来提升影响力。模仿就是其中之一，如果在谈话中，一个人模仿了对方的肢体语言，那么对方就会因有好感而向他靠拢。</span><span style="line-height: 1.8em;">这种技术在VR中不难实现。因为每个人的动作都能得到追踪，所以讲话人的虚拟化身可以被编程为模仿所有观众而不被发觉。</span><span style="line-height: 1.8em;">更让人毛骨悚然的是，一个人的所有面部特征也能被软件轻松捕获，然后转移到某虚拟化身中去。斯坦福大学的几项研究<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>，如果一个政治家的面容可以被修改成与每个选民有几分相似，那么哪怕这种修改极其轻微，也会对选票结果产生质的影响。</span></div><div><span style="line-height: 1.8em;"><br></span></div><div>实验设置了一场模拟竞选，并给参与者们和真实候选人分别<a href="http://display.oecr.com" target="_blank" class="relatedlink">照相</a>。之后，每位候选人的照片被变形 为与每位参与者依次相似。<span style="line-height: 1.8em;">他们发现，如果参与者的面部特征有40%被合成到候选人的脸上，参与者们丝毫不会发现图片已被篡改。但是这张合成图却能极大影响投票结果，使参与者们更倾向于支持“合成候选人”。</span><span style="line-height: 1.8em;">虚拟世界里的任何东西都不会长久。因此，当我们迈进这个新天地时必须小心，要知道，眼见的不一定为实。</span></div><div
