Device yaw in degrees using gyroscope.

[synasir]

I am trying to determine the device's yaw in degrees using the gyro sensor on my S3. I am using Erel's sample code to get the gyro data but I have no idea on how to use the X,Y,Z data. Can anyone help me on this. Thanks!

Which device are you using? Most devices do not have a gyroscope sensor.

The Samsung S3 mini, your sensor app is showing the gyroscope data when I run it.

You can read about the sensors here: Motion Sensors | Android Developers

I think that you need to use the orientation sensor instead of the gyroscope.

The X of the orientation sensor gets the azimuth of the compass. I need to get the yaw of the device i.e with the device in front of you and tilting the device to the left or right. Thanks.

The accelerometer can do that. Hold your device like a steering wheel and this will show the angle it's tilted.

Sub Process_Globals
    Dim Accelerometer As PhoneAccelerometer
End Sub

Sub Globals
   Dim lblAngle As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
      lblAngle.Initialize("")
      lblAngle.TextSize = 20
      Activity.AddView(lblAngle, 40%x, 45%y, 20%x, 30dip)
    End If
End Sub

Sub Activity_Resume
    Accelerometer.StartListening("Accelerometer")
End Sub

Sub Activity_Pause (UserClosed As Boolean)
    Accelerometer.StopListening
End Sub

Sub Accelerometer_AccelerometerChanged (X As Float, Y As Float, Z As Float)
   lblAngle.Text = "Angle = " & Round(ATan2D(Y, X))
End Sub

Ok, thanks. Will try that.:sign0098:
