我们讨论了三个实验,研究如何虚拟的肢体和身体可以来感觉像真实的肢体和身体。第一个实验表明,一个虚拟的手臂出现在一个人的肩膀伸出的所有权的错觉,可以产生一个人的隐藏的真实的手的触觉刺激和同步刺激看到的虚拟手。第二个实验表明,这种错觉可以通过人隐藏的真实的手和虚拟手的同步运动来产生。第三个实验表明,当采用脑机接口通过运动想象而没有任何触觉刺激来移动虚拟手时,可以产生较弱形式的错觉。我们讨论相关的研究表明,所有权错觉可能会产生整个身体。这对于科学地理解身体所有权和一些实际应用具有重要意义。
We discuss three experiments that investigate how virtual limbs and bodies can come to feel like real limbs and bodies. The first experiment shows that an illusion of ownership of a virtual arm appearing to project out of a person's shoulder can be produced by tactile stimulation on a person's hidden real hand and synchronous stimulation on the seen virtual hand. The second shows that the illusion can be produced by synchronous movement of the person's hidden real hand and a virtual hand. The third shows that a weaker form of the illusion can be produced when a brain–computer interface is employed to move the virtual hand by means of motor imagery without any tactile stimulation. We discuss related studies that indicate that the ownership illusion may be generated for an entire body. This has important implications for the scientific understanding of body ownership and several practical applications.
