First look: Kinect for Windows v2 Developer Preview SDK
Longtime readers know that I have great enthusiasm for the Kinect sensor as a revolutionary NUI technology. Now I can report that I was accepted to the Developer Preview program, and my new Kinect for Windows sensor arrived today.
The packaging goes out of its way to make you feel special: when the box opens, the first thing you see is a panel that reads “Developer Preview” under the K4W logo. Beneath that is a panel of K4W stickers.
Unpacking the Kinect for Windows v2 sensor.
The sensor itself comes with a couple of snazzy decals.

Also, the Developer Preview SDK shipped last week, so I took the whole package for a spin.
There are five sample apps with native (C++/Direct2D) and managed (C#/XAML) solutions:
- BodyBasics-WPF.exe / BodyBasics-D2D.exe
- ColorBasics-WPF.exe / ColorBasics-D2D.exe
- CoordinateMappingBasics-WPF.exe / CoordinateMappingBasics-D2D.exe
- DepthBasics-WPF.exe / DepthBasics-D2D.exe
- InfraredBasics-WPF.exe / InfraredBasics-D2D.exe
Unfortunately, we don’t get any Windows Store app demos – all of the included demos run on the desktop only.
After hooking up everything, including the charmingly prototypical router box, I ran the BodyBasics demo. And nothing happened. Hmm.
The router box that supplies power and connects the sensor to the computer through USB3.0.
I checked the cables and scrutinized the very bright LEDs (blue means the sensor is connected to computer, apparently). Installed the drivers on a different computer, got the same result.
So I consulted the online docs and found out that the KinectService needs to be running. This lives in theC:ProgramDataMicrosoftWindowsStart MenuProgramsKinect for Windows SDK v2.0 folder. D’oh.
With that little bump overcome, the demo apps run fine.

In Visual Studio 2013, all of the sample code builds without a hitch. The API seems well designed. For example, here’s how to get the body models in C#:
- // for Alpha, one sensor is supported
- this.kinectSensor = KinectSensor.Default;
- if (this.kinectSensor != null)
- {
- // get the coordinate mapper
- this.coordinateMapper = this.kinectSensor.CoordinateMapper;
- // open the sensor
- this.kinectSensor.Open();
- // get the depth (display) extents
- FrameDescription frameDescription =this.kinectSensor.DepthFrameSource.FrameDescription;
- this.displayWidth = frameDescription.Width;
- this.displayHeight = frameDescription.Width;
- this.bodies = newBody[this.kinectSensor.BodyFrameSource.BodyCount];
- // open the reader for the body frames
- this.reader = this.kinectSensor.BodyFrameSource.OpenReader();
- // set the status text
- this.StatusText =Properties.Resources.InitializingStatusTextFormat;
- }
- else
- {
- // on failure, set the status text
- this.StatusText = Properties.Resources.NoSensorStatusText;
- }
Easy peasy. The Microsoft.Kinect namespace has everything you need to interact with the sensor at a high level of abstraction. The classes in the Microsoft.Kinect.dll assembly, extracted by using Ildasm, are appended below.
With this preview of the new SDK, I’m more convinced than ever that Kinect is going to revolutionize NUI. I hope that someday soon this hardware will be miniaturized and built into every laptop and slate.
