Kinect status and setup the Kinect for interaction

Introduction 

The article will give you a getting started with kinect for windows sensor SDK 1.8 and how the kinect for interaction works. I am going to use the kinect sdk 1.8 and a WPF project using visual studio. 

Pre-Requisites   

• Visual studio 2012
• .NET 4.5
• Kinect for windows sensor device.
• Kinect for Windows SDK (http://go.microsoft.com/fwlink/?LinkID=323588)
• Kinect for Windows Developer Toolkit (http://go.microsoft.com/fwlink/?LinkID=323589) 

Kinect for window sensor status

Create a WPF Application project WPFKinect18 using visual studio 2012.

Add the following references:From the C:\Program Files\Microsoft SDKs\Kinect\v1.8\Assemblies\ folder, add Microsoft.Kinect.dll.

From the C:\Program Files\Microsoft SDKs\Kinect\Developer Toolkit v1.8.0\Assemblies\ folder, add Kinect.Toolkit.dll, Kinect.Toolkit.Controls.dll and Kinect.Toolkit.Interaction.dll

Add the KinectSensorChooserUI to the MainWindow to get the Status of the Kinect sensor. Plugged, unplugged, powered.

And a label control to display the Kinect status change. 

Kinect not connected

Kinect is initializing (you can see the status by hovering on it)

Kinect Connected

Setup the Kinect for interaction

Copy these “KinectInteraction180_32.dll, KinectInteraction180_64.dll” dll’s on the output directory of your project. As shown below (you can find these dll’s in the source code of this article.)

Now change the “SensorChooserOnKinectChanged” event by the following code.

On the mainwindows.xaml

<k:kinectuserviewer k:kinectregion.kinectregion="{Binding ElementName=kinectRegion}" height="150" primaryusercolor="Violet" usercoloringmode="HighlightPrimary" horizontalalignment="Right" verticalalignment="Bottom">
</k:kinectuserviewer>

You can see the user depth image on the right bottom of the screen. User is detected in-front of Kinect but not active. The user is looking gray colored

Now the user is active and moving hand and its depth image becomes colored. And you can also see the user’s hand, both hands are track able. You can switch hand cursor control from left hand to right hand easily.

Adding the Kinect tile button inside the Kinect region

<k:kinecttilebutton click="ClickMe_Click" label="Click Me" x:name="ClickMe" />

In the MainWindow.cs page.

private void ClickMe_Click(object sender, RoutedEventArgs e)
        {
            KinectStatus.Content = "Clicked me";
        }

Hover hand on the button on the button

Taking your hand towards Kinect sensor, like pushing a button. Partial pushed button

Pressed button looks like this.

Take you hand back to fire up the click event of this button.

For scrolling area on the Kinect: grip your figures and scroll from left to right and right to left.

Using the code
