normal output

Brain-computer Interface ( BCI) is a communication system that connects brain and computer or other electric equipment. The character of BCI is that it can make a person communicate with the outside world without depending on peripheral nerves and muscle's normal output channels.

脑机接口（Brain computer interface，BCI）是连接大脑和计算机或其它电子设备的通信系统，其特点是能够使人在完全不依赖肌肉和外围神经的情况下实现人脑与外界的通信与交流。

Brain-computer interface ( BCI) is a brand-new interface between the human brain and the computer. BCIs give their users communication and control channels that do not depend on the brain's normal output channels of peripheral nerves and muscles, but accepts commands encoded in neurophysiological signals.

脑机接口（BCI）是一种全新的人机接口方式，它不依赖于脑的正常输出通道（外周神经与肌肉系统），而是直接从大脑获取与外界通讯的信息。

For example, an attacker might close one or more of them so that the next file you open is also where normal output goes.

例如，攻击者可能会关闭它们中的一个或多个，以使得您打开的下一个文件同时也是正常的输出位置。
