On June 1, children's day. 6月1号,儿童节。 After mechanical exoskeleton project establishment and investment budget two weeks, Zhejiang ** ci( brain-computer interface) laboratory. 距离机械外骨骼项目立项及投入预算后两周,浙**ci(脑机接口)研究室。 A researcher whole face sits down in front of the screen grudgingly, two colleague hands and feet put on the eeg headgear to him deftly, then turns on the controller one by one, the preparation starts experiment of this day. 一名研究员满脸不情愿地在屏幕前坐下,身后的两名同事正手脚麻利地给他套上eeg头套,然后又逐一打开控制器,准备开始这一天的实验。 „Will Brother Chen, why always I, I really like not working as the white mouse, we draw lots to be good tomorrow? Who pulls out to whom does the experiment.” “陈哥,为什么老是我啊,我真的不像当小白鼠了,明天咱们抽签好不好？谁抽到谁就来做实验。” By people that he is called Brother Chen named Chen strength, is the double branch doctor of biological and electrical engineering, is hundred years of rare talent in the bci domain ---- Naturally, this technology from birth to the present not over 100 years, but in any event, his talent is obvious to all internally. 被他叫做陈哥的人大名叫陈力,是生物学和电气工程学的双科博士,在bci领域属于百年都难得一见的天才----当然,这个技术从诞生到现在都不超过一百年,不过无论如何,他的才华在国内有目共睹。 „vermilion, do not struggle, our entire laboratory is weakest on your egg signal, tests to achieve the optimal result with you.” “朱啊,你就别挣扎了,咱们整个实验室就你的egg信号最弱,用你来测试才能达到最优的结果。” „Said again, making you sit for day in this, does not need to look that the data does not need to calculate the model, closes one's eyes to think, isn't relaxed?” “再说了,让你在这坐一天,又不用看数据又不用算模型,就闭着眼睛动动脑子,还不轻松吗？” Sits the person on chair name is vermilion Xuan, he is also a computer doctor, contributed many unprecedented convolution neural network algorithm models in the bci project of Zhejiang University, but experiments to conduct the final revision adjustment stage now, his work gradually was also short. 坐在椅子上的人叫朱轩,他本身也是一个计算机博士,在浙大的bci项目中贡献了许多突破性的卷积神经网络算法模型,不过现在实验已经进行到最后的修正调整阶段,他的工作也逐渐少了下来。 Therefore, he was then regarded the white mouse naturally, every day arrives at the laboratory, first was pressed on the chair to put on the egg headgear, starts to test they most recent mechanical arm. 于是,他便自然而然地被当成了小白鼠,每天一到实验室,第一时间就被摁到椅子上戴上egg头套,开始测试他们最新研发的机械手臂。 Today is also same, vermilion Xuan has not even had the breakfast with enough time, had started a he day of test work. 今天也是一样,朱轩甚至连早饭都还没来得及吃,就已经开始了他一天的测试工作。 Is listening to Chen strength words, he about is shaking the head to say discontentedly: 听着陈力的话,他不满地左右摇着头说道: „You were too ruthless, he before made the monkey operation of experiment correctly to give back to a banana to eat, I? In this sits is one in the morning, does not drink to me the saliva.” “你们太狠了,他么的以前做实验的猴子操作正确了还给口香蕉吃,我呢？在这一坐就是一上午,连口水都不给我喝。” „I am not really clear, I with monkey difference which?” “我真就不明白了,我跟猴子差哪了？” „...... The monkey grew hair, you are not long.” “......猴子长毛了,你没长。” „I, if also long woolen cloth?” “那我要是也长毛呢？” „....... That I also give your banana to eat. Ok, do not pull, device attachment, close your eyes, I wear the eye-shade to you, I must first adjust your mi signal.” “.......那我也给你香蕉吃。行了,别扯了,设备连接完了,闭眼,我给你戴眼罩,我要先校正你的mi信号。” The so-called mi signal is the motor imagery brain wave signal, this real-time control attempts to direct the muscle group in the brain, when the neural pathway died of suffocation is unable to transmit, after the egg headgear catches this signal, the mi translation model that the brain opportunity the signal inputs the decoder, the decoder according to vermilion Xuan and he brings the team that writes to translate the mechanical electrical signal this signal, thus the movement of director mechanical arm. 所谓的mi信号就是运动想象脑电波信号,这种信号发生于大脑尝试指挥肌肉群,但神经通路被堵死无法传递时,通过egg头套捕获到这种信号后,脑机会将信号输入解码器,解码器根据朱轩和他带的团队写的mi翻译模型把这种信号翻译成机械电信号,从而指挥机械臂的动作。 vermilion Xuan arm had tied up firmly on the chair arm rest, the goal is to simulate the arm incapacitating, or loses the condition of arm. 朱轩的手臂已经被牢牢地绑在椅子扶手上,目的是为了模拟手臂失能、或者失去手臂的状态。 „Sits this chair each time I always some not good feelings, but must wear the eye-shade ....... the total feeling next second of leather whip to pull out.” “每次一坐上这个椅子我总有种不好的感觉,还要戴眼罩.......总感觉下一秒皮鞭就要抽上来了。” „....... Comes, Xiaoya, goes to prepare the good candle to bring us.” “.......来,小雅,去把我们准备好的蜡烛拿过来。” „Lying trough! You are serious!” “卧槽！你玩真的啊！” vermilion Xuan arm pulls out suddenly, the entire chair was pulled by him jumps. 朱轩的手臂猛然一抽,整个椅子都被他拉得一跳。 Because there is a constrained tape limit system, his arm movement has not carried out successfully, one side is places the mechanical arm to contract on the contrary suddenly, nearly rubs clear/pain Ya of standing on one side. 因为有拘束带限制,他的手臂动作并没有成功执行,反倒是放在一边的机械手臂猛然收缩,险些擦到站在一边的楚雅。 „senior brother, your response was also too big ....... the mi signal propagation to be normal, data intensity ok, can conduct the test.” “师兄,你这反应也太大了吧.......mi信号传递正常,数据强度ok,可以进行测试了。” „It is not, I did not respond in a big way, I was feared that you really took the candle to drop me, I remember that previous time you have said that under what unconsciousness condition must test the command capability of reflection signal to mechanical arm, now you do wasn't this matter?” “不是,我不是反应大,我是怕你们真拿蜡烛滴我,我记得上次你们就说过,要测试什么无意识状态下反射信号对机械手臂的指挥能力,现在你们干的不就是这事儿吗？” clear/pain Ya goes to a helpless look to Chen Litou, later says: 楚雅向陈力投去一个无奈的眼神,随后开口说道: „What to do, does Brother Chen, return the candle?” “咋办,陈哥,还上蜡烛吗？” „On, why not on, but must first measure the foundation operation first. Come, vermilion, your front has an apple, imagines, moves about 20 centimeters your arm toward right, then puts out a hand to grasp the apple.” “上啊,干嘛不上,不过得先测完基础操作先。来,朱啊,你面前有一个苹果,想象一下,把你的手臂向右移动二十厘米左右,然后伸手去抓苹果。” „Right, the position was right, what kind of, can feel?” “对对对,位置对了,怎么样,能感受到吗？” vermilion Xuanshou on seat had the facial expression of joke, under the eye-shade, he has closed the eye to enter the ponder condition, later, the mechanical arm starts to move. 座椅上的朱轩收起了玩笑的神情,在眼罩之下,他已经闭上了眼睛进入沉思状态,随后,机械臂开始移动。 The speed of mechanical arm is quick, the five fingers joint expands and contracts unceasingly, tries to hold front apple. 机械臂的速度很快,五指关节不断屈伸,试图去抓住面前的苹果。 „Very good, you have bumped into, can feel the current signal?” “非常好,你已经碰到了,能感受到电流信号吗？” The vermilion Xuan slight nod, replied: 朱轩微微点头,回答道: „Shoulder has the numb feeling, but must establish this feeling in the logical system of brain is not easy, I cannot respond that this electric current from touching of mechanical arm to object, in the brain must circle a great-circle to revise the logic.” “肩膀有酥麻感,不过要把这种感觉重新建立在大脑的逻辑系统里不容易,我根本反应不过来这种电流是来自于机械臂对物体的触碰,脑子里要绕一大圈才能修正逻辑。” „This operation too counter- intuition, Brother Chen, can you develop one system, transforms the sense of touch signal instead to write about in the brain the pressure signal?” “这种操作太反直觉了,陈哥,你们能不能开发一套系统,把压力信号转换成触觉信号反写到大脑里？” „In doing was doing, now the deeploop project does is this, this just did not take the budget to want on ultra to calculate that after waiting ultra to be counted, resolves to attempt the electrical signal.” “在搞了在搞了,现在deeploop项目做的就是这个,这不是刚刚拿了预算要上超算嘛,等超算上了之后把电信号解算出来就可以尝试了。” „You concentrate on the electric stimuli now, so long as after the special training, the formation condition reflection is not difficult. Come, you continue, now you had three fingers to bump into the apple, can feel the electric current? Gets hold , the power frequency should speed up.” “不过你现在还是专注电刺激吧,只要经过专门的训练,形成条件反射还是不难的。来,你继续,现在你有三根手指已经碰到苹果了,能感受到电流吗？握紧一些,电流频率应该会加快。” vermilion Xuan nods, replied: 朱轩点了点头,回答道: „Can feel, I should five fingers bump into now, five points that before buried in advance have the electric stimuli to feed back. The middle finger, thumb and index finger feedback region frequency is highest, should be consistent with the stress logic.” “能感觉到,我现在应该五根手指都碰到了,之前预埋的五个点位都有电刺激反馈。中指、拇指、食指反馈区频率最高,应该是跟受力逻辑一致的。” „That did not have the issue. Now lifts the apple, does the arm pressure stimulation area have the response?” “那就没问题了。现在把苹果举起来,手臂压力刺激区有反应吗？” „Some responses, but exciting is very very strong, isn't this weight of apple?” “有反应,但是很刺激很强啊,这根本就不是苹果的重量吧？” Hears vermilion Xuan words, clear/pain Ya looks at each other one with Chen strength, on the face the same fashion shows the joyful look. 听到朱轩的话,楚雅和陈力对视一眼,脸上同时流露出欣喜的神色。 This naturally is not the apple, now on the mechanical arm is grasping, is Chen strength specially the ball attachment of dumb bells looks for from the gym. 这当然不是苹果,现在机械手臂上握着的,是陈力专门从健身房找来的哑铃的球形端。 Goal that they do that to confirm mechanical arm the real function on fma electric stimuli feedback system purely. 他们这么做的目的,纯粹是为了验证机械手臂上的fma电刺激反馈系统的真实作用。 It looks like from the present result, like vermilion Xuan after the user of training, is can definitely without drawing support from vision and haptic feedback, through buries in body other in advance has the electrode stimulation of sensation spot to judge oneself grasp grasps the object the basic situation. 从现在的结果看来,像朱轩这样经过训练的使用者,是完全可以在不借助视觉和触觉反馈的情况下,通过预埋在身体其他有感知部位的电极刺激来判断自己所抓握物体的基本情况的。 If after the long-term training, forms one set of perfect thought processing logic to these electric stimulis, the user even can judge the object shape through the mechanical arm directly, this will give their technology to bring the leaping change. 如果经过长期训练,对这些电刺激形成一套完善的思维处理逻辑,使用者甚至可以直接通过机械手臂来判断物体形状,这将给他们的技术带来飞跃性的改变。 Naturally, such training is inevitably difficult, because its essence is to destroy human to the inherent logic that the limbs controls, then establishes one set newly machinery -based logic, this even start to study to from the infancy be more difficult. 当然,这样的训练必然是艰苦的,因为它的本质就是打碎人类对肢体控制的固有思维逻辑,然后重新建立一套新的基于机械的思维逻辑,这甚至要比从婴儿阶段开始学习要更加困难。 However, regarding their users, this difficulty, is really not anything. 不过,对于他们的用户来说,这点困难,实在是算不上什么。 Thinks of here, Chen strength opens the mouth to explain: 想到这里,陈力开口解释道: „This truly is not the apple, this is dumb bells. vermilion, you studies quick, seems like our systems basically available, come, puts down the dumb bells, we then measure other.” “这确实不是苹果,这是一个哑铃。朱啊,你学的很快嘛,这么看起来咱们这套系统基本上还是可用的,来,把哑铃放下,我们接着测别的。” „....... Brother Chen, I sat over half a month on this chair, studied can not be quick? Wait, your stopper what strange thing to my hand in?” “.......陈哥,我都在这椅子上坐了大半个月了,学的能不快吗？等等,你塞了什么奇奇怪怪的东西到我手上？” „This weight, how this shape...... I felt the cylinder? The pressure among each fingers is similar, you wait/etc, I trade only the hand to touch.” “这重量,这形状......我怎么感觉是圆柱形的？各个手指间的压力都差不多,你等等,我换只手摸一下。” Is saying, vermilion Xuan while moved another mechanical arm, had been grasped the object that grips after him slowly, starts to point at to probe the object with one shape. 一边说着,朱轩一边移动了另一只机械手臂,缓缓靠近他已经被抓握住的物体后,开始用一只手指去试探物体的形状。 This is an extremely counter- intuition, with the touching operation completely different behaviors of normal person, side he at the matter of doing, on a pressure transmitter with the aid of finger, gives the object on hand to trace. 这是一个极为反直觉、也跟正常人的触摸操作完全不同的行为,他所在做的事情,是借助一根手指上的压力传感器,去给手上的物体进行描边。 The finger after the object has transferred one, vermilion Xuan is basic has the judgment. 手指围绕着物体转过一圈之后,朱轩心里基本已经有了判断。 „I know that was anything.” “我知道是什么了。” „Cylinder, probably more than ten centimeters, cannot judge soft and hard, but the curve ....... first removes my first thinking that strange thing, that answer only has one.” “圆柱形的,大概有十几厘米长,判断不出来软硬,不过略带弧度.......首先排除我第一个想到的那种奇怪的东西,那答案只有一个。” „Banana.” “香蕉。” „It is not, Brother Chen, your he really planned that makes me eat the banana?!” “不是,陈哥,你他么真打算让我吃香蕉啊？！” Chen strength happily is nodding to him, later says: 陈力欣慰地对着他点点头,随后开口说道: „Eats the banana certainly to eat the banana, but is not only eats that simply.” “吃香蕉是肯定要吃香蕉的啦,但是不仅仅是吃那么简单。” „Come, you try to bare the banana skin now, then oneself feed in your mouth.” “来,你现在试着把香蕉皮剥开,然后自己送进你嘴里。” „....... This a little excessive Brother Chen, the movement was too fine, is very difficult.” “.......这有点过分了陈哥,动作太精细了,很难啊。” „Also must do again fine, we can count on that in the later user does live does not have the fine movement? The exhausted banana is daily, even this cannot complete, how our brain machines also counted on that changes others life?” “再精细也要做,难道我们能指望以后的用户生活里没有精细动作吗？剥香蕉已经非常日常了,连这个都做不好,我们的脑机还怎么指望改变人家的生活啊？” „Let alone, opened mouth quickly!” “别说了,快张嘴！”
