近年来，通过脑电波控制电脑进而控制其他设备的技术渐渐发展起来。在今年的CES大展上，多家公司展示了“脑机接口”产品。也许要不了几年，这类产品就会流行起来。
The emerging mind-reading technology
by Julia Boorstin
It's not the self-driving cars, flying cars or even the dish-washing robots that stick out as the most transformative innovation at this year's Consumer Electronics Show (CES): It's the wearable gadgets that can read your mind.
stick out 突出、显眼
transformative /trænsˈfɔːmətɪv/ adj. 使彻底改观的（由transform加后缀-ative变成形容词）
innovation /ˌɪnəˈveɪʃ(ə)n/ n. 创新
wearable /ˈweərəb(ə)l/ adj. 可穿戴的（由wear加后缀-able变成形容词）
gadget /ˈɡædʒɪt/ n. 小装置、小玩意儿
There's a growing category of companies focused on the "Brain-Computer Interface." These devices can record brain signals from sensors on the scalp（头皮） and translate them into digital signals. This industry is expected to reach $1.5 billion this year, with the technology used for everything from education and prosthetics（假肢学）, to gaming and smart home control.
category /ˈkætəɡri/ n. 种类、类别
focus /ˈfəʊkəs/ v. 聚焦（focus on就是“聚焦在、专注于”）
interface /ˈɪntəfeɪs/ n. 界面、接口
device /dɪˈvaɪs/ n. 设备
record /rɪˈkɔːd/ v. 记录
signal /ˈsɪɡn(ə)l/ n. 信号
sensor /ˈsensə(r)/ n. 传感器
translate /trænsˈleɪt/ v. 转变、转化
billion /ˈbɪljən/ n. 十亿
gaming /ˈɡeɪmɪŋ/ n. 电脑游戏
control /kənˈtrəʊl/ n./v. 控制
I tried a couple of wearables that track brain activity at CES last week, and was surprised to find they really work. NextMind has a headset that measures activity in your visual cortex（大脑皮层） with a sensor on the back of your head. It translates the user's decision of where to focus his or her eyes into digital commands.
wearable /ˈweərəb(ə)l/ n. 可穿戴设备
track /træk/ v. 跟踪、追踪
activity /ækˈtɪvəti/ n. 活动
headset /ˈhedset/ n. 戴在头上的装置
measure /ˈmeʒə(r)/ v. 测量
visual /ˈvɪʒuəl/ adj. 视觉的
command /kəˈmɑːnd/ n. 命令
"You don't see with your eyes. Your eyes are just a medium," NextMind CEO Sid Kouider said. "Your vision is in your brain, and we analyze your vision in your brain and we can know what you want to act upon and then we can modify that to basically create a command."
medium /ˈmiːdiəm/ n. 媒介
vision /ˈvɪʒ(ə)n/ n. 视觉
analyze /ˈæn(ə)laɪz/ v. 分析
modify /ˈmɒdɪfaɪ/ v. 修改、改变
basically /ˈbeɪsɪk(ə)li/ adv. 基本上、实质上（由basic加后缀-ally变成副词）
Wearing a NextMind headset, I could change the color of a lamp – red, blue and green – by focusing on boxes lit up with those colors. The headset also replaced a remote control. Staring at a TV screen, I could activate a menu by focusing on a triangle in a corner of the screen. From there, focusing my eyes, I could change the channel, mute（静音） or pause video, just by focusing on a triangle next to each command.
light /laɪt/ v. 点亮、照亮（lit是过去分词）
remote /rɪˈməʊt/ adj. 遥远的（remote control就是遥控器）
stare /steə(r)/ v. 盯着看、凝视
activate /ˈæktɪveɪt/ v. 激活（由active加后缀-ate变成动词）
triangle /ˈtraɪæŋɡ(ə)l/ n. 三角形（由angle加上表示三的前缀tri-）
channel /ˈtʃæn(ə)l/ n. 频道
Another company focused on the brain-computer interface, BrainCo, has the FocusOne headband, with sensors on the forehead measuring the activity in your frontal cortex. The "wearable brainwave visualizer（观测仪）" is designed to measure focus, and its creators want it to be used in schools.
headband /ˈhedbænd/ n. 绑在头上的带子
frontal /ˈfrʌnt(ə)l/ adj. 前部的（由front加后缀-al变成形容词）
brainwave /ˈbreɪnweɪv/ n. 脑电波
focus /ˈfəʊkəs/ n. 焦点、关注点（这里指注意力是否集中）
creator /kriːˈeɪtə(r)/ n. 创造者（由create加上表示人的后缀-or）
"FocusOne is detecting the subtle electrical signals that your brain is producing," BrainCo President Max Newlon said. "When those electrical signals make their way to your scalp, our sensor picks them up, takes a look at them and determines, 'Does it look like your brain is in a state of engagement? Or does it look like your brain is in a state of relaxation?'"
detect /dɪˈtekt/ v. 监测
subtle /ˈsʌt(ə)l/ adj. 细微的
president /ˈprezɪd(ə)nt/ n. 总裁
determine /dɪˈtɜːmɪn/ v. 确定、决定
state /steɪt/ n. 状态
engagement /ɪnˈɡeɪdʒmənt/ n. 参与（由engage加后缀-ment变成名词）
relaxation /ˌriːlækˈseɪʃ(ə)n/ n. 放松（由relax加后缀-ation变成名词）
BrainCo also has a prosthetic（假肢的） arm coming to market later this year. It detects muscle signals and feeds them into an algorithm that can help it operate better over time, Newlon said.
muscle /ˈmʌs(ə)l/ n. 肌肉
feed /fiːd/ v. 把…放入机器、把…输入系统
algorithm /ˈælɡ(ə)rɪð(ə)m/ n. 算法
operate /ˈɒp(ə)reɪt/ v. 运作
over time 随着时间的推移
"The thing that sets this prosthetic（假肢） apart is, after enough training, a user can control individual fingers and it doesn't only rely on predetermined gestures. It's actually like a free-play mode where the algorithm can learn from him, and he can control his hands just like we do," Newlon said.
set something apart 使某事物与众不同
individual /ˌɪndɪˈvɪdʒuəl/ adj. 个体的、单个的
rely /rɪˈlaɪ/ on 依靠、依赖
predetermined /ˌpriːdɪˈtɜːmɪnd/ adj. 预先确定的（由determine的过去分词加上表示“之前”的前缀pre-）
gesture /ˈdʒestʃə(r)/ n. 手势、动作
mode /məʊd/ n. 模式
