@Hemanth: Our runtime can either use live data from the sensor, or via Kinect Studio, pre-recorded color and depth feeds. Kinect Studio is a new Tool that ships in the Kinect for Windows Toolkit 1.5.0. It allows you to record and playback these feeds.
When you play them back, they are in your application just like a live feed, so you can see the Skeletal Tracking data, etc...
KinectSensorChooser got more investment in v1.5. Look in the DeveloperToolkit Browser under "Components". KinectSensorChooser is now a UI-less (logic only) class that finds Kinect Sensors for you app. KinectSensorChooserUI is a WPF based UI experience that uses KinectSensorChooser.
SkeletonViewer still exists...we added a KinectManager to the viewers project...that the Viewers current rely on. Would love feedback. Perhaps you could go to http://bit.ly/KinectSDKForums and report how it goes and what questions or feedback you have.
@Mark- I'd recommend you consider which UI Framework will meet your application needs, and pursue languages that work with that UI Framework. Our Toolkit contains samples using WPF, XNA, Direct3D, and Direct2D. Once you choose the framework that will meet your needs, the language choice is clear.
@aL3891- Nothing to announce about fingers. Common request.
@wowps- Kinect for Windows sensors may not be used with an Xbox 360. Kinect for Xbox sensors may not be used in licensed deployments on Windows (they may be used by Devs...but we strongly recommend devs migrate towards Kinect for Windows sensors).
@Burkholder - look at the set of related functions that Bas mentions. I'll have to check if we have a Color -> Depth mapping. Most scenarios I've seen that deal with both color and depth, start with Depth, and get the appropriate Color for each "pixel" by calling GetColorPixelCoordinatesFromDepthPixel.
@Bas - yes, the naming and locations of all those "sensor space mapping" methods is a bit suspect. We've not yet been able to go make sense of them, but have many suggestions from people like you to do so. We understand the need.
@Ahmad - Not with our beta2 build. You may not, in the same process, use 2 kinects (with skeletal tracking turned on both). I believe that having 2 apps on the same machine...would allow both apps to use a different Kinect and get skeletal tracking going.
@Mo Relax - take a look at the readme and the documentation and the program files entry for the sdk and you'll find the location. %KINECTSDK_DIR%\Samples\Bin has a compiled version of that app. %KINECTSDK_DIR%\Samples\ also (in b2) has a .zip file with the source code for all the C#/C++ samples. (unzip to my docs, or related for best results). We are considering building a sample browser app (like Xbox SDK and DirectX SDK) to make it easy to run the different samples, or install the source code, or jump to docs about the sample.
