Thread: Electronic compass on iGO?

Pardon my English.

Yea, Sygic Truck has the ability to use compass for accurate heading, very cool. I wish IGO soon add it.

how useful can "accurate heading" be in an "on-road" navigation program?

When you rotate your unit, GPS response slow but compass fast. Nuff said, I'm not going to justify usefulness, each to his/her own.

Is this kind of like the apple's compass function?

Have no idea since I do not use/have apple product. But considering that GPS only compute direction if you are moving, having a compass as part of GPSNav doesn't hurt, just makes it better.

iGO should add the function that using gps for directions when moving on road and using internal electronic compass when stop moving.

Unfortunately, for the electronic compass, first it must be
supported from the application.
And after with utilities with lua code.
Here is an example which
Enable internal compass
In java.
This must be in the primo apk.


Java example...

import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

public class InternalCompassOrientationProvider implements SensorEventListener, IOrientationProvider
{
private IOrientationConsumer mOrientationConsumer;
private final SensorManager mSensorManager;
private float mAzimuth;

public InternalCompassOrientationProvider(Context context)
{
mSensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
}

//
// IOrientationProvider
//

/**
* Enable orientation updates from the internal compass sensor and show the compass.
*/
@Override
public boolean startOrientationProvider(IOrientationConsumer orientationConsumer)
{
mOrientationConsumer = orientationConsumer;
boolean result = false;

final Sensor sensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
if (sensor != null) {
result = mSensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_UI);
}
return result;
}

@Override
public void stopOrientationProvider()
{
mSensorManager.unregisterListener(this);
}

@Override
public float getLastKnownOrientation()
{
return mAzimuth;
}

//
// SensorEventListener
//

@Override
public void onAccuracyChanged(final Sensor sensor, final int accuracy)
{
// This is not interesting for us at the moment
}

@Override
public void onSensorChanged(final SensorEvent event)
{
if (event.sensor.getType() == Sensor.TYPE_ORIENTATION) {
if (event.values != null) {
mAzimuth = event.values[0];
if (mOrientationConsumer != null)
mOrientationConsumer.onOrientationChanged(mAzimuth, this);
}
}
}

i mean the electronic sensor (compass) from our android device

like Sygic....

in Primo

we are already use the compass , but , it comes from map , gps .

NOT from internal sensor

from that we need Java
