意思是说广告性太强。。。因为之前知道一些朋友也遇到过这个问题，所以直接向他们请教。问题应该是提供的描述、截图与上传的App内容不符，所以修改了一下copyright，再次上传审批。

OpenNI的安装问题

问题描述：Kinect买了好久了，今天终于空下来，有机会来研究下。按照教程安装OpenNI、Sensor、NITE后，然后启动as3-server，报openNI.dll丢失的错误。

问题分析：查看C:\Program Files\OpenNI\bin64;C:\Program Files (x86)\OpenNI\Bin目录，有openNI.dll文件。

问题解决：系统环境变量从
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Common Files\Thunder Network\KanKan\Codecs;C:\Program Files (x86)\ICBCEbankTools\Gemplus\GemSafe Libraries\BIN\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\OpenNI\bin64;C:\Program Files (x86)\OpenNI\bin;C:\Program Files (x86)\PrimeSense\NITE\bin
改为
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Common Files\Thunder Network\KanKan\Codecs;C:\Program Files (x86)\ICBCEbankTools\Gemplus\GemSafe Libraries\BIN\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\OpenNI\bin64;C:\Program Files (x86)\OpenNI\Bin;C:\Program Files (x86)\PrimeSense\NITE\Bin
一切ok了！

iOS录音问题

问题描述：
AD的iPad版有一个鼓掌互动的应用。换了前后三套类库，如下：
SCListener：https://gist.github.com/72914
AVAudioRecorder：http://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioRecorder_ClassReference/Reference/Reference.html
SpeakHere：http://developer.apple.com/library/ios/#samplecode/SpeakHere/Introduction/Intro.html

问题分析：
首先使用SCListener，发现模拟器上正常使用，但是真机不能监听声音。再使用AVAudioRecorder，发现还是有以上真机不能监听的问题。
最后使用SpeakHere，可以监听，但是有一个bug。就是：真机上，声音监听过就不能播放video，而模拟器上一切正常。

问题解决：
原来录音和播放使用的是一个通道，需要手动设置当前通道的状态。而模拟器上就可以忽略这种限制。
修改通道为录音的代码如下：
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryRecord error:nil];
修改通道为播放的代码如下：
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayback error:nil];
播放前修改为播放，录音前修改为录音，一切OK了。

PS：后来发现只要修改对应的通道，AVAudioRecorder在真机上也可以用了。

Kinect驱动

驱动有三种：
OpenNI：Open Natural Interface，没有电驱模块。

Libfreenect：OpenKinect，由号称第一个破解Kinect的Hector Martin发起，有很多geek簇拥Mac，所以本来的目标平台是Linux和Mac，现在有Windows移植。

CLNUL：由NUI的大神AlexP （开发过PS3的Windows驱动），目标平台是Windows7，搭配OpenCV。
