中学生VOA英语阅读之科技让“空气”吉他成为现实Advanced Technology Turns “Air Guitar” Into Real InstrumentLearning to play guitar requires a lot of practice, perseverance, and at least in the beginning, painful blisters on fingers.学习弹吉他不仅需要勤奋练习，持之以恒，对于初学者来说，手上还会磨出水泡。Playing the “air guitar” is a lot easier and can be a lot of fun, but does not produce any sound.相对来说，空气吉他既容易又有趣，但是没有声音。Now, researchers from Goldsmiths, University of London and the University of Sussex used gesture recognition technology to build a digital instrument that turns the air guitar motions into music.伦敦大学金斯密斯学院和苏塞克斯大学的科研人员将手势识别技术运用于电子乐器中，让空气吉他也能演奏音乐。“What we have done is really take a whole bunch of different sensors, accelerometers, gyroscopes, magnetometers, pressure-sensitive stuff, and then combine that with a mobile phone, which has the computational power to actually drive real-time music synthesis.”“我们利用不同的传感器、加速器、陀螺仪、磁力仪、压感器等，与手机连接，利用计算机实际上推动实时的音乐合成。”A small pad with eight buttons fits neatly into the palm of the left hand, while the strumming hand holds an oversized electronic pick.By pressing the buttons, the player chooses chords, which can be played with the strumming motion of the right hand.左手持一块小遥控器，上面有八个按钮，另一只手持着超大号电子拨片。左手可以选择不同按钮，确定和弦，右手拨动就能演奏。“So we mapped out the entire guitar and bass fretboard, and we did acoustic and electric guitar.And we did single notes and chords, and the total, I think, came to something well over a thousand samples.So theres a huge amount of possibility.”“我们设计出完整的吉他和低指板，还有原声吉他和电子吉他两种。我们还设计了乐谱和和弦。综合所有，我觉得空气吉他可以弹奏上千种音乐。所以，空气吉他具有很大的可能性”。With just a few minutes of practice, someone who has never played a guitar can learn to play a simple riff.仅需要几分钟练习，即使从未学习过吉他的人也可以演奏一段简单的音乐。“I did not think I can do it, but today I believe I can, and it is great!”“我从未想过我会弹吉他，但今天我相信我可以，真是太赞了！”The Kurv guitar plays through a smartphone or a tablet via Bluetooth, freeing the headphone jack for connection to an amplifier.这种吉他通过蓝牙连接智能手机或者平板电脑，不需要用耳机孔连接扩音器。Players can choose from three instrumentselectric, acoustic and bass guitar, and the pick is sensitive to the intensity of the strumming motion.演奏者有三种选择，电子吉他、原声吉他以及低音吉他，电子拨片对弹奏动作的强度非常灵敏。Its inventors are currently crowdsourcing funds for mass production, planned to begin in March 2016.目前，空气吉他的研制者正在寻求资金支持，有望在2016年3月进入大规模生产阶段。单词及例句详解1 practice prktis练习；实践；（医生或律师的）业务；惯例；例句1.Genuine knowledge comes frompractice.; Practice yields genuine knowledge.实践出真知。2.It is thepracticein Britain to drive on the left.车辆靠左行驶是英国的制度。3.Weve made our plans, and now we must put them intopractice.我们已订好计划，现在应付诸实施了。2 perseverance p:svrns毅力 ；韧性；不屈不挠的精神；例句1.High school exam required perseverance, asas there is perseverance, you will be able to enter.考高中需要有恒心，只要有恒心，你一定能考上。2.He became a champion at last in virtue of hisperseverance.凭着坚韧不拔的精神，他终于成为冠军。3.He succeeded by means ofperseverance.他是通过坚持成功的。3 painful peinful痛苦的；（肉体）疼的；费力的，（工作）困难的；讨厌的，使人厌烦的；例句1.A verypainfulsurmise arose concerning her character.对她的人格产生了一种令人难堪的猜度。2.The sting of a jellyfish is verypainful.让水母刺着是很痛的。3.Extension of the injured arm waspainful.把受伤的胳膊伸展开是很疼的。4blister英 blst(r) 美 blst n.水疱; 水肿; 疱; 气泡vt.& vi.（使）起水泡vi.（使表皮等）涨破，爆裂变形复数：blisters过去式：blistered过去分词：blistered现在分词：blistering第三人称单数：blisters例句1.I was bothered about the blister on my hand.手上起的水泡让我心烦。2.It is not a good idea to burst a blister.把水泡挑破不是个好主意。3.The bandage must be put on when the blister breaks.水疱一旦破了就必须用绷带包扎起来。5 gesture dest手势， 姿势；举止，动作；古语仪态；计算机光笔指令；例句1.He made a rudegesturewith his digits.他用手指做了一个不礼貌的手势。6 recognition reknin认识，识别；承认，认可；褒奖；酬劳；例句1.A sudden smile ofrecognitionflashed across his face.他脸上掠过一丝笑意，表示认识对方。2.The photo has faded beyondrecognition.相片已经模糊，不能辨认。3.He was rewarded inrecognitionof his service.他的贡献得到认可而受到嘉奖。7 technology teknldi科技（总称）；工业技术；工艺学；总称术语；例句1.About 30 major medical centers in the United States have xenon CAT scantechnology.美国大约有30家主要医疗中心有氙气CAT扫描仪技术。2.The results of this research can be applied to new developments intechnology.这项研究成果能应用于新的技术开发方面。3.Anyone who tries to resist the spread of newtechnologyis fighting a losing battle.想阻止新技术传播的人注定要失败。8 digital ddtl数字的；数据的；手指的；指状的；例句1.A device which converts digital-type information into analog quantities is called a digital-to-analog converter.改变数字类型信息成模拟的数量的一套设备被称为一个digital-to-analog变换器。2.Indigitalsignal technique, a signal that uses a positive(or negative) excursion and ground as the two binary signal states.在数字信号技术中，用正(或负)向电压与地两个电平来表示二进制“1”和“0”的一种信号3.Pertaining to a device that operates in a proportional or continuous manner, such as an analog amplifier.
