Imagine tapping into the mind of a coma patient, or watching one's own dream on YouTube. With a cutting-edge blend of brain imaging and computer simulation, scientists at the University of California, Berkeley, are bringing these futuristic scenarios within reach. Using
functional Magnetic Resonance Imaging (
fMRI) and computational models, UC Berkeley researchers have succeeded in decoding and reconstructing people's dynamic visual experiences – in this case, watching Hollywood movie trailers. As yet, the technology can only reconstruct movie clips people have already viewed. However, the breakthrough paves the way for reproducing the movies inside our heads that no one else sees, such as dreams and memories, according to researchers. "This is a major leap toward reconstructing internal imagery," said Professor Jack Gallant, a UC Berkeley neuroscientist and coauthor of the study to be published online Sept. 22 in the journal
Current Biology. "We are opening a window into the movies in our minds."

While volunteers watched movie clips, a scanner watched their brains. And from their brain activity, a computer made rough reconstructions of what they viewed. Scientists reported that result Thursday, Sept. 22, 2011 and speculated such an approach might be able to reveal dreams and hallucinations someday. In the future, it might help stroke victims or others who have no other way to communicate, said Jack Gallant, a neuroscientist at the University of California, Berkeley, and co-author of the paper.

智能电表将能发现你正在看什么
Münster应用科学大学的研究人员
发现，根据智能电表记录的用电量数据是可能判断出
用户正在观看哪个电视节目。从理论上说，通过分析用电模式，也可能识别出DVD上正在放的是哪部电影。
进行此类模式识别分析的关键是电影中大量的明暗变化、大数据量和没有多少其它用电设备的干扰。研究人员测试了EasyMeter智能电表，电表将用电数据每2秒发送到服务器。这些用电量信息可以被提取出来，分析用户可能观看的电视节目。
