[XBOX360]Johnny Lee（做Wiimote应用的人）博文谈Project Natal，现为微软硬件工作_360游戏_游戏资讯_玩家
导读： 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亾
If you#39;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#39;t seen the vision video, it is definitely worth checking out:
Now, I should preface by saying I don#39;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#39;t really reveal any details that haven#39;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#39;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#39;s pretty neat building the future..安卓手机牛牛游戏保暖防嗮泳装教育培训公司
