MIT:这双AI袜子暴露了你的行动

原标题:MIT:这双AI袜子,暴露了你的行动

编者按:本文来自微信公众号“量子位”(ID:QbitAI),作者:萧箫,36氪经授权发布。

你的行动,全都在这双袜子的掌控之中:

MIT:这双AI袜子暴露了你的行动

无论是单脚站立、还是扭腰、走路,这双袜子都能通过脚上压力的变化,来预测你的行动:

MIT:这双AI袜子暴露了你的行动

最关键的是,材料制造简单。

不需要集成大量高精度传感器,用织衣服的方法,就能做出检测效果非常棒的袜子。

这双有着“超能力”的袜子,由MIT开发,现在登上了Nature子刊:

MIT:这双AI袜子暴露了你的行动

这样准确的预测效果,到底是怎么做到的?

结合AI,准确预测各种姿势

袜子的运动检测原理,本身很简单:

利用机器学习,将人体姿势、与触觉脚印关联起来,从而预测人体的运动。

MIT:这双AI袜子暴露了你的行动

这是因为,人在从一个姿势,改变成另一个姿势时,由于脚上的压力发生变化(如重心从右脚转移到左脚),触觉脚印也会发生相应变化。

通过采集大量数据、利用自监督学习,对模型进行训练,就能预测人体的运动:

MIT:这双AI袜子暴露了你的行动

然而,如何才能让这种织物,既能大量生产、又能保证检测精细?

要知道,批量生产的话,就不可能再精准地对传感器位置一个个进行设计。

为此,这双袜子采用了2种织物混合制成。

包括普通纺织纤维腈纶纱、与能够传感力度的功能性纤维。

如图,功能性纤维中包含有力度传感材料。

因此,这种袜子既保留了袜子本身的柔软性,又具有检测动作的能力。

两条织线之间,会有交叠。

因此,当感知到负载压力的时候,两条线就会相互挤压,里面的传感材料就能通过交叉点,感知到力度的大小。

此前,许多可穿戴设备,需要大量高精度传感器,才能保证测量的准确性。

但与现有的可穿戴电子设备不同,这种袜子的设计,可以被用于大型服装生产中,极大降低成本。

不过,这种袜子在生产时,也可能会出现一些问题。

如果批量制造的话,有些袜子的传感器,可能会无法正常工作。

这时候,就需要结合机器学习算法,来识别和调整袜子中的某些传感器,来及时找出工作不了的传感器部分。

具体检测效果,也确实不错。

例如,扭扭腰。系统预测的动作和正在做的动作,几乎完全一致:

下蹲。机器所预测的姿势,也几乎与真正的姿势完全一样:

试试走路?就连步态、步幅也都基本一致:

再来看看下楼梯。除了步幅以外,其他也基本是完全一样了。

而且,这种智能织物,还不止能用在袜子上。

还有背心、膝盖、手套系列

除了智能袜子,来自MIT的研究人员,还搞出了背心、膝盖、手套等各种系列的智能织物:

MIT:这双AI袜子暴露了你的行动

这套神奇的衣服,原理基本与袜子一样,也是由类似的织物构成。

感知到压力后,利用两条织线交叠产生的压力,就能对人所做的动作进行预测。

这套衣服,可以用于病人的运动和康复训练。

如果家属允许,可以用来监护病人在医院、病患的健康状况,以免他们在独处时跌倒、或者是失去意识。

当然,也能给机器人穿。

通过学习这套衣服中的数据,机器也许就能理解,人类是如何做动作的,从而学会做出各种不同的动作。

有了这套衣服,机器人也许就能“拥有”触觉。

这项研究的第一作者,是一名来自MIT的华人博士小姐姐Yiyue Luo。

Yiyue Luo中学毕业于广州市执信中学,曾在伊利诺伊大学香槟分校就读本科,目前是一名MIT的博士三年级学生。

她的研究方向,是制造、智能织物和触觉传感。
