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 there's 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.

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 instruments——electric, 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。
