如何以100美元的价格打造自己的VR耳机 (How you can build your own VR headset for $100)

My name is Maxime Peroumal. I’m 16 and I built my own VR headset with my best friends, Jonas Ceccon and Gabriel Combe. And it ended up costing us $100.

我叫马克西姆·佩鲁马尔(Maxime Peroumal)。我今年16岁，我和最好的朋友Jonas Ceccon和Gabriel Combe共同打造了自己的VR耳机。最终花费了我们100美元。

I started programming when I was 13, thanks to my math teacher. Every Monday and Tuesday, my friends and I used to go to his classroom to learn and practice instead of having a meal at the cafeteria.

多亏我的数学老师，我13岁时才开始编程。每个星期一和星期二，我和我的朋友过去常常去他的教室学习和练习，而不是在自助餐厅吃饭。

I spent one year building a very basic 8-bit OS from scratch and competing in robotics contests with my friends.

我花了一年的时间从头开始构建一个非常基本的8位操作系统，并与朋友们参加了机器人竞赛。

I then got interested in VR and with my friends we agreed that it would be really cool to create our own world in VR where we could spend time after school. But facing the fact that an Oculus was $700 at the time, we decided to build our own headset.

然后，我对VR产生了兴趣，并与我的朋友们达成共识，在VR中创建我们自己的世界，在那里我们可以放学后花些时间真的很酷。但面对当时Oculus售价为700美元的事实，我们决定制造自己的耳机。

使所有人都能使用VR？ (Making VR accessible to everyone?)

It was because of an anime called Sword Art Online where the main character is in a virtual reality RPG that I fell in love with VR. I wanted to understand every aspect of it.

因为爱上了VR，这是因为一个名为Sword Art Online的动漫，其中的主要角色是虚拟现实RPG。我想了解它的各个方面。

I bought the cheapest components I could and we started by learning the very basics of the physics and math behind VR (proper acceleration, antiderivatives, quaternions…). And then we re-invented VR. I wrote WRMHL, and then FastVR with Gabriel. Putting all of this together, we ended up with a $100 VR headset.

我买了最便宜的组件，然后开始学习VR背后的物理和数学基础(适当的加速，反导数，四元数……)。然后我们重新发明了VR。我写了WRMHL ，然后写了Gabriel的FastVR 。综合所有这些，我们最终购买了售价100美元的VR头盔。

完全可破解的VR耳机和开发套件 (A fully hackable VR headset and development kit)

To speed up VR development time, we built FastVR, an open-source SDK for developers that is easy to understand and customize. It works like this:

为了加快VR开发时间，我们构建了FastVR，FastVR是面向开发人员的易于理解和自定义的开源SDK。它是这样的：

The core headset computes the position of the headset in space;
核心耳机计算出耳机在空间中的位置；
The position is sent from the headset to WRMHL, and part of the CPU’s power is dedicated to reading those messages;
该位置从耳机发送到WRMHL ，并且部分CPU的功能专用于读取这些消息；
Then FastVR retrieves the data and uses them to render the VR game.
然后， FastVR检索数据并将其用于渲染VR游戏。

Everything you need to build the headset has been open-sourced and can be hacked.

构建头戴式耳机所需的一切均已开源，并且可以被黑客入侵。

为什么要开源？ (Why open source?)

I want to make VR mainstream. So I reached out to Oussama Ammar, one of the co-founders at The Family. I talked to him about setting up a company and launching a Kickstarter.

我想使VR成为主流。因此，我与The Family的联合创始人之一Oussama Ammar进行了接触。我和他谈过有关成立公司和启动Kickstarter的问题。

But he convinced me that for now, it’s better to wait on starting a business, to keep meeting others who have the same goals, and to keep learning.

但是他说服了我，现在最好是等着创业，继续结识志同道合的人，并且不断学习。

We took a trip to Silicon Valley and Oussama introduced me to the chief architect at Oculus, Atman Brinstock. And they gave me some precious advice: make all of this open source.

我们去了硅谷，Oussama向我介绍了Oculus的首席架构师Atman Brinstock。他们给了我一些宝贵的建议：将所有这些开源。

下一步？ (The Next Step?)

There are still a lot of technical points that we want to improve.

我们还有很多技术要改进的地方。

Our big focus right now is on a standalone VR headset, which we already have as a simple version, and cheaper 3D tracking.

目前，我们主要关注的是一款独立的VR头戴式耳机，我们已经将其作为一个简单版本和更便宜的3D追踪功能。

All of this will be released soon.

所有这些都将很快发布。
