如果你好奇我为何很久没更新博客了，现在我终于可以告知你们是因为我一直在为Xbox的Natal做事，如果你还没有看过他的构想视频，你应该去看。

先说明：我对你们在E3上看到的一切并无贡献。一个云集了勤奋与智慧兼备的人员的团队才是那一切的幕后推手，而我的工作的部分则是让你在起居室感受到和E3现场演示内容一样的振奋——在进行此项工作是一个同样聪颖然而规模更大的团队。不幸是很多具体的部分我还不能在进一步公布之前说太多

作为一个在界面与扫描方面浸润将近10年的人，我保证这是一个令人惊讶的软件与硬件的集合，有几次我把部分技术秀给同行学者，都把他们震的合不拢嘴。

Natal的3D扫描本身就是一个强大的设备，能反馈详细的3D信息，效果类似与昂贵的激光范围探测系统，但成本却低廉很多。深度摄像头能不同光照环境下在探测出物体表面上的点集，这些都是普通摄像头无法媲美的。

但当你有了点集和环境3D信息后，你要让机器将点集诠释成人体。这里便是让同行惊奇的地方，我们团队开发的人体追踪演算法在Computer Vision的艺术应用领域（电影，游戏）遥遥领先，其应变能力和演算性能超越所有我见过的专业领域的同类产品，民用产品则更不用提了。这个项目给我一个微型“曼哈顿计划”的感觉，来自世界各地的学者云集于此让这一切成为现实。

我们都希望有朝一日会拥有自己的Holodeck（星际迷航中的虚拟操作界面，与之类似就是少数派报告里的），今天我们的迈出的一部相当可观。

微软和Xbox部门应为承担如此一项前途远大的项目得到嘉奖，你可以随时对自己说“要是####成真多好”，但说出“让我们集合资源令其成真，并且花费多少在所不惜”则就不那么简单了。我们真的是在创造未来呢。

If you've been wondering why my project blog has been pretty quiet, I can finally say it is because I have been helping Xbox with Project Natal. If you haven't seen the vision video, it is definitely worth checking out:

Now, I should preface by saying I don't deserve credit for anything that you saw at E3. A large team of very smart, very hard working people were involved in building the demos you saw on stage. The part I am working on has much more to do with making sure this can transition from the E3 stage to your living room - for which there is an even larger team of very smart, very hard working people involved. The other thing I should say is that I can't really reveal any details that haven't already been made public. Unfortunately.

Speaking as someone who has been working in interface and sensing technology for nearly 10 years, this is an astonishing combination of hardware and software. The few times I’ve been able to show researchers the underlying components, their jaws drop with amazement... and with good reason.

The 3D sensor itself is a pretty incredible piece of equipment providing detailed 3D information about the environment similar to very expensive laser range finding systems but at a tiny fraction of the cost. Depth cameras provide you with a point cloud of the surface of objects that is fairly insensitive to various lighting conditions allowing you to do things that are simply impossible with a normal camera.

But once you have the 3D information, you then have to interpret that cloud of points as "people". This is where the researcher jaws stay dropped. The human tracking algorithms that the teams have developed are well ahead of the state of the art in computer vision in this domain. The sophistication and performance of the algorithms rival or exceed anything that I've seen in academic research, never mind a consumer product. At times, working on this project has felt like a miniature “Manhattan project” with developers and researchers from around the world to coming together to make this happen.

We would all love to one day have our own personal holodeck. This is a pretty measurable step in that direction.

Xbox and Microsoft deserve an enormous amount of credit for taking on such an ambitious project. It’s one thing to say “Wouldn’t it be cool if…”, but it’s another thing entirely to say, “let’s dedicate the resources to really make it happen inventing whatever needs to be invented along the way.” I have to say it's pretty neat building the future.

JOHNNY LEE 是谁，估计这里很多人又要再问一遍了。。。233

我就知道一定是胖子lee参与的，微软GJ
任天堂哭吧。。。

人才资源的大集结~
尽管全都是类广告的形容词~
但听起来确实挺high的~

这个应该是那个拿WII来搞研究的华人，看过他的研究视频，当时就感觉蛮震撼的

恩，我最喜欢这一句。

认识怎样，不认识又怎样？

微软下手太快了

这就是未来啊~~~

——用来作UI操作无敌了

肯定有李胖子的一手啊。。

3D摄像头。。太赞了，能扫描一下自己么

原來胖子已經被吸收了
難怪他對這玩意沒有批評

听说当初胖子的视频上网后，老任和微软都去招揽胖子，胖子最后选择了MS

natal快点成真吧..

肯定还有人质疑，johnny lee算哪根葱，他说的话算啥

换成我选也时选ms，n范围太窄了，只会卖游戏机和扑克
