My name is Tom Chi.

我叫纪良育(Tom Chi)

I spent two years of my life

我花了两年时间组建用户体验团队。

building the user experience team

for the Google X division of Google,

隶属Google的Google X部门

and it's a place I affectionately call

我把这个地方亲切地称为科幻部。

the Department of Science Fiction

because of the futuristic nature

因为我们接手的项目

of the types of projects we took on:

都是些未来科技。

self-driving cars,

自动驾驶汽车，

Google Glass,

谷歌眼镜，

and other things that you'll see soon enough.

还有其他一些大家马上就会看到的东西。

So, for those who haven't heard of this project,

可能有人还没听说过这个项目，

this is what Google Glass looks like.

这就是谷歌眼镜的样子。

It allows you to overlay digital things into your eye sight

它可以在你的视野中叠加一些数码讯息，

while still maintaining being part of the world.

并让你继续留在现实世界。

So, if I, you know, were to pull out my cell phone

你们知道，如果我拿出手机来看，

and look into it, I'm basically out of this world now,

我就基本上脱离了现实世界，

like, I'm in my own little cell phone-tablet world, what have you.

就像是我进入了自己的手机世界。

But, Google Glass has the vision of allowing us

但是，谷歌眼镜的理念是

to continue to be in the world

让我们置身现实的同时，

but also have access to the digital things that we need and love.

也能获取我们我们需要和喜爱的数码讯息。

Now, I am going to ask you a real simple question about Google Glass:

关于谷歌眼镜，我想问你们一个很简单问题，

how would you prototype this experience?

你们会怎么去试制这种体验？

How long do you think it would take you

你们觉得要花多长时间

to make the first working version of the headset display?

做出第一款可以用的头戴显示装置？

Okay, a little bit on the long side.

好，有点偏久。

The answer is one day.

答案是一天。

And here's what it looked like.

这是它的样子。

So, basically the magic piece is the coat hanger.

基本上，最奇妙的就是这个晾衣架。

The coat hanger, I bent it in a specific shape

我把晾衣架弯成特别的形状，

and the top loop goes around your neck

上面这一圈绕在脖子上，

and then the bottom loop rests against your chest

下面这一圈靠在胸口。

and it allows me to carry a piece of plexiglass

这样我就能带上一块有机玻璃

on with a little sheet protector.

和一小片护套。

So these are the things you put your book reports in

这些东西就是用来装读书报告

so they don't get wet,

以免弄湿了。

I literally got at the drug store.

其实我是从药店买来的。

You know, have it out at the end of the plexiglass

你看，把它装在有机玻璃末端，

and then it gets projected onto with the pico projector

连接笔记本电脑的微型投影机

that's connected to a Netbook.

就可以投射在上面。

And using this set-up, within one day

采用这种形式，

we're already able to start having the experience

一天之内我们就可以开始体验

of what it looks like to have digital things

把数码讯息叠加到真实世界中

overlaid on your physical world,

会是什么样子。

be able to move around with it,

可以戴着走来走去，

用笔记本电脑来试验

and also use the Netbook to try out

软件上面大量的各种各样的创意。

tons and tons of different ideas around software.

Now, after you start getting something like that working,

有了这样一个可以用的东西之后，

you know, a really important problem comes up,

你看，一个很重要的问题出来了，

like you're wearing this thing on your head,

好像是头上戴着这个东西，

it's like a pair of glasses,

就像是一幅眼镜，

so you don't have a mouse or a keyboard or a touchscreen,

所以没有鼠标，没有键盘，也没有触摸屏，

all the ways you are used to interacting with a machine.

所有这些和机器互动的东西都没有。

So, we thought for a second,

所以，我们想了一下，

那么，我们可能可以做点什么

well, maybe we could do something

like, you know, what was shown in <i>Minority Report</i>.

就像是<关键报告>里演的。

So, for folks who haven't seen that,

如果谁没看过的话，

basically Tom Cruise is manipulating software

基本上汤姆·克鲁斯就是用手在面前

with his hands in front of his face

操作着软件

and photos are flying over here

照片就飞到这里

and his email is over here

他的邮件就飞到这里

and so on and so forth.

如此这般。

So I'll ask the the same question again,

那我再问同样的问题，

how long do you think it would take

你们觉得要花多长时间

to have the real experience of doing something like that?

来得到这样一种真实的体验？

Two years, OK.

两年，好吧。

Somebody said one day.

有人说一天。

45 minutes.

45分钟。

So here's how it looks.

它是这个样子。

So you wear the thing that we saw that first time

戴着我们刚看到的这个东西，

because you need some way to go project things,

因为要某种方式来投影，

but what happens is we got two hairbands,

所以就有了两个发圈，

which I think was the hardest part we had to do,

我觉得最难做的事

ask people for their hairbands.

是向别人要她们的发圈。

But you put one hand in each hairband

把发圈戴在手上

and attach that hairband,

我们在发圈上

we tied a fishing line.

绑了一条鱼线。

And the fishing line goes over the top of a whiteboard

鱼线从上面绕过一个白板

and then goes down to this little assembly

连接到下面这个装置，是用胶带粘在地板上的

that's taped to the floor.

And what this means is

这就意味着

every time I move my hand in any direction,

每当我向任意方向挥手

it adds tension to the line

就会拉紧这根线

and it does the following with the assembly on the floor.

然后就传到地上的这个装置。

So, the other end of the fishing wire is attached to a chopstick

鱼线的另一端连着一根筷子

and it's not because I'm Asian,

不是因为我是亚洲人

there's just a cafeteria nearby,

只不过餐厅就在旁边，

I don't just carry chopsticks on me.

我没有说我身边总是带着筷子，

But, I tied it to the end of a chopstick,

那，我把它绑在筷子的一端，

I clipped it into a binder clip,

用长尾夹夹住

and then put it over a pen,

然后装到一支钢笔上，

and basically what happens then

基本上就会这样

is when you move your arm

当挥动手的时候

and it produces tension on the wire,

这根线就会有张紧力，

the chopstick comes down like a lever

筷子就会象杠杆一样

and clicks a presentation clicker,

向下按遥控器。

one hand moves the presentation forward,

一只手控制幻灯片向前滚动

the other hand moves the presentation backwards.

另一只手控制幻灯片向后滚动

So this was built in 45 minutes

所以这是45分钟做出来的

and that meant shortly afterwards,

这意味着不用多久

we were having experiences

我们就能体验

like looking at an image gallery

好像在看一部相册

and saying, "next image,

然后说：“下一张，

next image,

下一张，

previous image,"

前一张，“

or looking at our emails and saying,

或是看着邮件说，

"let me click into this email,

“我要点这封邮件，

let me click reply now."

我要点回复了。”

And this was exactly the experience of what it was like

这种体验的确就像是在用手来控制软件。

to go control software with your hands.

And ultimately, what it taught us is

最后我们认识到

we probably shouldn't have this in the product.

也许不应该把它用到产品里面去。

We learned a lot of things

我们弄懂了很多东西

about the social awkwardness of it

它在社交上的笨拙

and some of the ergonomic aspects of it

和它人体工学的样子，

that you couldn't have figured out

这些是不能靠想象来弄明白的。

ahead of just thinking about it.

And, ergo the second prototyping rule,

因此快速成型的第二条原则

which is "doing is the best kind of thinking."

就是“动手是最好的思考方式。”

They teach you to think a lot in school,

学校里会教你们要多多思考，

but I think it is a little bit overrated.

但我觉得有一点夸张。

Now last example, you know,

在上一个例子中，

事实上谷歌并不是第一个

actually Google is not the first team

that's tried to go make something like this

尝试做这样这样的东西的团队。

and if you search for headset display,

如果搜索“头戴式显示器”，

you get tons of images of teams

会找到大量的团队图片

that have built various systems like this,

做出了各种类似的系统，

but I can tell you at a glance

但我可以说，一眼看去

that none of these pieces of hardware

没有一件能让客户舒服地戴上15分钟的，

are comfortable to wear for more than 15 minutes

可能就除了那边的头盔，

except for maybe the helmet over there,

but then you got to wear a helmet.

可那样你就得带着个头盔了。

So, you know, how would you go figure out a way

所以，要怎样才能想出一种办法

to go wear something like this comfortably?

能够舒服地佩戴这样的东西？

The answer is really basic materials:

答案是很简单的材料：

modeling wire,

造型铁丝，

paper,

clay,

纸

粘土，

and using something like this

用这些东西

is able to make something look like a pair of glasses really quickly.

可以很快地做出像眼镜一样的东西。

I cut out pieces of clay that weighed

我切下一块粘土

exactly the same amount as the electronic components

重量正好等于

放在装置里面的电子元件。

that we were talking about putting on the device,

wrapped it in paper so you didn't get clay on your face,

用纸包起来，以免粘土沾到脸上

and then taped it to the modeling wire in various places

然后用胶带缠到铁丝的不同位置

to go experiment with how a pair of glasses could fit on you.

试试看什么样的眼镜才更合适。

And, we discovered something really important then.

我们就发现了很重要的一点。

Like, if you look at this drawing on the bottom,

好像底下这张图

it turns out that the weight of a pair of glasses

原来一副眼镜戴着感觉有多重

is actually mostly perceived

其实取决于鼻子上有多重。

through how much weight is on your nose.

And, it also turns out that your ears can carry

而且，原来耳朵能够承受的重量

a lot more weight than your nose,

要远比鼻子多

and that is a totally different experiment,

这完全是另一个试验了，

you can ask me about that.

过后可以问我。

But, because of that fact,

不过，基于这个事实，

if you put weight behind your ears,

如果把重量放在耳朵后面

it allows your ear to go act like the fulcrum of a lever

就可以把耳朵当成杠杆的支点

and it then takes weight off of your nose on the front.

那就减轻了前面鼻子的负担。

And, actually, you can try this now, anybody with glasses,

其实大家可以试试看，戴着眼镜的人

if you push very gently on the back of your glasses,

如果你轻轻地压眼镜的后端

you'll find, actually your glasses feel tremendously lighter.

就会发现，感觉眼睛变得很轻了

Now, this meant that we not only discovered

这就表示我们不仅发现了

something interesting about how to go,

有趣的解决办法，

you know, that's useful for developing a device like this,

可以用来开发这样的装置，

we actually discovered something pretty fundamental

我们其实还发现了眼镜的本质特点

that never been discovered about glasses, period.

这在以前的眼镜时代从来没有发现过的。

So, if you have really heavy glasses,

所以，如果你有一副很重的眼镜，

you could do this and you would be more comfortable.

这样去做就会觉得很舒服。

Now, the last point I want to make is

我想说的最后一点是

about two types of learning

关于两种学习方式

because through the process of rapid prototyping,

因为快速成型的过程

you are able to learn very quickly.

可以让你学得很快。

It's a very specific type of learning.

这是一种很特别的学习方式。

The type of learning that you usually learn in school

通常在学校里的那种学习方式

I call book learning.

我称作“书本式学习”。

It comes from what humanity already knows

是来自人类已经知道的东西

and it's a necessary foundation for you guys to go and explore the world.

是你们去探索世界的必需的基础。

But there is a totally different type of learning,

但也有一种完全不同的学习方式，

which I call expansive learning,

我称为“扩展式学习“，

and this is the learning you do on behalf of humanity.

是作为人类的学习。

Right?

You are creating something new,

对吧？

这是在创造新的东西，

you are expanding into the possibilities,

是扩展到了不确定的领域，

and you're building the sphere of human knowledge in that process.

这个过程既是拓展人类知识的宝库。

And, we think about these things and as soon as you hear

我们觉得这些东西

like, ok, the infinite realm of possibilities

一听到无限的可能性

beyond the sphere of human knowledge,

人类知识的未知领域，

you might be thinking there's the scientists

你可能会想到那些科学家

at the Large Hadron Collider

用着大型电子对撞机

who have these amazing instruments,

这样的神奇的设备，

like that's their job, right?

好像这才是他们的工作，对吧？

But the truth is that this action is available to all of us,

但事实上这件事我们都可以做，

you know,

你知道吗？

it's not just for the scientists,

不仅仅是科学家，

it's also for the poet or the songwriter

还有诗人和作曲家

that expresses an emotion for the first time in a unique way.

首次用一种独特的方式来表达情感。

It's also for the person that has an amazing business idea

也可以是某个人有了奇妙的商业创意

that they're certain could help millions of lives.

确信可以帮助成千上万的人。

And, it's the realm of using paper, clay, and tape

用纸、粘土和胶带

in order to go find a new insight

可以在旧的科技中

in an ancient technology.

领悟到新的东西。

So now that you know a lot about rapid prototyping,

现在你们知道了很多快速成型的东西

I'm excited to see what you do with it.

我很期待看到你们用它来做出东西。

Thank you.

谢谢。
