Introduction

• Part 1: Setting up the Camera stream
• Part 2: Knowing the Device Attitude (Orientation)
• Part 3: Getting our data from Nimbus
• Part 4: Augmented our data to the camera stream

Prerequisites

• A Windows Machine with Windows Phone Developer Tools Installed (7.1 beta),
  downloadable from: [http://create.msdn.com]
• Basic knowledge in C#.NET or VB.NET programming language
  (we would be programming in c# in these tutorials)
• a pair of hands that can code 😀

Development

(a) the Camera Stream

1. Start Visual Studio 2010 / Visual Studio 2010 Express for Windows Phone. There are multiple templates that are available. We will choose the basic one for this application: ‘Windows Phone Application‘ and give your application a name. (If it prompts you, after pressing ok, on “which Windows Phone Platform you want to target for this application”, choose “Windows Phone 7.1”)
   
2. Go to the Design View of MainPage. Remove all the existing User elements in the design view such that there is only the “layoutroot” grid.
3. Set the page’s Supported Orientations to Landscape and Orientation to Landscape. Set the system tray visibility to false, This allows us to maximise the screen real estate.
   [cc lang=’xml’ line_numbers=’false’]SupportedOrientations=”Landscape” Orientation=”Landscape”[/cc]
4. Next, add a rectangle, of width 640 and height 480 to the layout root. Inside the rectangle, set the Fill property to “VideoBrush” type. Set its name to “ViewFinderBrush”:
   <Grid x:Name=”LayoutRoot” >
   <Rectangle Width=”640″ Height=”480″ >
   <Rectangle.Fill>
   <VideoBrush x:Name=”ViewFinderBrush” />
   </Rectangle.Fill>
   </Rectangle>
   </Grid>
   
5. Open the code view of the MainPage (MainPage.xaml.cs). You would only see the constructor of the MainPage.
6. add the using statement for “Microsoft.Devices” to the page, then declare a “PhotoCamera” variable. Name it “camera”[cc lang=’csharp’ line_numbers=’false’]using Microsoft.Devices;[/cc]
7. Next,

   override the OnNavigatedTo event for the page

   1. Initialize the PhotoCamera variable, “camera” inside the OnNavigatedTo event
   2. Set the videobrush’s source to the camera.
      [cc lang=’csharp’ line_numbers=’false’]protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
      {
      camera = new PhotoCamera();
      ViewFinderBrush.SetSource(camera);
      base.OnNavigatedTo(e);
      }[/cc]
8. Press “F5” to debug the application, set the device as the Windows Phone Emulator. You should see something like this, on the emulator and the phone, respectively:
   
9. Ta Da…. You now have an application with the camera stream in your application.
