South by Southwest (SXSW) Interactive专注于社交网站。ｔｗｉｔｔｅｒ就在０７年的South by Southwest (SXSW) Interactive赢得关注的。
Microsoft BizSpark Accelerator是South by Southwest (SXSW) Interactive中的一个创业公司比赛，有３２个公司。去年是第一届，今年的比赛从３月１５号开始。其中出现了很多有趣的网站，有不少利用各种AI作为核心技术。
比如Siri，提供个人虚拟助理（virtual personal assistant），将语音识别，机器学习，网络结合起来。
再比如Khush，提供一个iphone app叫做Ladida，用户对着ｉｐｈｏｎｅ清唱，然后程序会自动帮你配上乐曲。。牛逼吧。
貌似3月16号比赛就结束了，可是我没找到结果。。。汗
到这里看ｍｉｔ ｒｅｖｉｅｗ。
看到一则关于微软Natal的小道消息，全文照抄如下：
Yesterday, I was invited to a private Project Natal sneak peek. The event was held at the beautiful EZ Studios in New York City. I met with a member of the Project Natal product team. She gave us a brief explanation of the Natal vision and gave us only a few technical details:
- RBG camera
- depth camera
- Current games will not be compatible with Natal
- “Project Natal” is a code name and will not be the final name of the product
- [Work in progress] Use voice commands to control services i.e. music, videos, movies
- [Work in progress] Facial recognition
- [Work in progress] Use gesturing to navigate the XBOX menu structure
- [Work in progress] Distinguishing between the primary player and a spectator
- [Work in progress] Suppressing background noise
Once we were briefed — we were given the opportunity to play a dodge ball (like) game. It was a great experience. There I was (without a controller) standing, kicking, swatting, jumping and working up a sweat. The responsiveness of the Natal system was incredible and very accurate. If I physically moved forward, back, swung faster or slower my dodge ball avatar responded in kind.
“Our advances in computer vision and audio-signal processing,” Malvar notes, “have enabled the development of Project Natal, a new level of experience for Xbox, in which user gestures and voice take the place of the standard game controller.– Rico Malvar, managing director of Microsoft Research Redmond
语音识别可以多国语言么？可以自定义么？
搞了这么久，终于要上市了。
突然有个疑问，natal能同时追踪多人么？
据这篇报道，natal不光有手势，姿态识别，还有语音识别，表情识别（当玩家表情厌烦的时候，游戏难度会降低么？）。
The key aspect of Project Natal is its ability to recognize gestures, but the system also includes the ability to respond to voice commands and facial or object recognition. These last two technologies are well established at this point. Despite some consistency issues and a literal learning curve, voice recognition is commonly found in cell phones and speech-to-text typing applications. Facial recognition, often viewed with trepidation for its big-brother security implications, is now widely available in consumer point-and-shoot cameras.
