Get Your Hand Action From Microsoft Band Using Accelerometer Sensor

This article shows how to get the heart beat rate from Microsoft Band in Windows Phone.

Create a new Windows Phone project and add the Microsoft Band SDK and select Manage NuGet Packages as in the following screen:



Now search for and install the Microsoft Band SDK as in the following image:



After installing the Microsoft SDK, ensure that the Proximity capability has been added to the manifest file as in the following image:



Enable Proximity

Add the following code to the Package.appmanifest file. Right-click the appmainfest file and select View Code to add the code.

<DeviceCapability Name="bluetooth.rfcomm" xmlns="http://schemas.microsoft.com/appx/2013/manifest">
   <Device Id="any">
      <Function Type="serviceId:A502CA9A-2BA5-413C-A4E0-13804E47B38F" />
      <Function Type="serviceId:C742E1A2-6320-5ABC-9643-D206C677E580" />
   </Device>
</DeviceCapability>

Design the page as shown in the following image.



The first step is to connect to the Band. To make a connection, the band and the device must be paired with Bluetooth to each other. To get the paired Band and establish a connection use the Band Client Manager. 

1. Add the namespace.
   

   using Microsoft.Band;
   using Microsoft.Band.Sensors;

2. Get the list of paired Bands using the following code.
   

   IBandInfo[] getPairedDevice=await BandClientManager.Instance.GetBandsAsync();

3. Connect to the band.
   

   using(IBandClient client=await BandClientManager.Instance.ConnectAsync(getPairedDevice[0]))
   {
   
   }

4. Ensure the user has consented before getting the heart beat rate from the Band.
   

   if (client.SensorManager.Accelerometer.GetCurrentUserConsent() != UserConsent.Granted)
   {
   }

5. Start the sensor to read the device axis.
   

   await client.SensorManager.Accelerometer.StartReadingsAsync();

6. Create an event handler to read each and every change of the Band axis.
   

   client.SensorManager.Accelerometer.ReadingChanged += Accelerometer_ReadingChanged;
   void Accelerometer_ReadingChanged(object sender, BandSensorReadingEventArgs<IBandAccelerometerReading> e)
   {
   
   }

7. Write the following code to change the hand image axis.
   

   void Accelerometer_ReadingChanged(object sender, BandSensorReadingEventArgs < IBandAccelerometerReading > e)
   {
       var xAxis = e.SensorReading.AccelerationX;
       var yAxis = e.SensorReading.AccelerationY;
       var zAxis = e.SensorReading.AccelerationZ;
       var actionRotation = yAxis * 90;
       this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () = > {
           myHand.Projection.SetValue(PlaneProjection.RotationYProperty, actionRotation);
       });
   }

Now start the Windows Phone app and connect with your Microsoft band and click the Start button to get the band action.
