Link between Accelerometer and composant in xaml


Accelerometer is used mostly on Games , then we can move objects with just moving our device and it's so easy to do that.


Using the code

Fisrt of all we create an instance of Accelerometer :

Accelerometer a = Accelerometer();

Then we precise the TimeBetweenUpdates, means that how many time you want to update the change of accelerometer. For Example : 

a.TimeBetweenUpdates = TimeSpan.FromMilliseconds(10);

Then you define the Event CurrentValueChanged that will be called after any update to inform us the new x,y,z axes then we start.

a.CurrentValueChanged += new EventHandler<SensorReadingEventArgs<AccelerometerReading>>(a_CurrentValueChanged);


so the responsible method that execute after update is a_CurrentValueChanged : 

void a_CurrentValueChanged(Object sender, SensorReadingEventArgs<Microsoft.Devices.Sensors.AccelerometerReading> sr)
           Dispatcher.BeginInvoke(() => UpdateUI(sr.SensorReading));
       double x, y, z;
       void UpdateUI(Microsoft.Devices.Sensors.AccelerometerReading ar)

           Vector3 xyz = ar.Acceleration;

           x += xyz.X;
           y += xyz.Y;
           z += xyz.Z;

After we get the three demension of accelerometer , we can now bind it to an object.

we create for example an Ellipse : 

<Ellipse Width="50" Height="50" Fill="Blue" Name="cercle" />

on the code behind we link the Margin of the Ellipse by the Vector xyz : 

cercle.Margin = new Thickness(x * 15, -y * 15, -x * 15, y * 15);

You can modify the Speed of the Object by multiplying  coordinates.


I thing it become so clear to work with accelerometer , you can now create your First Game !
