Getting the tap position in Google Glass

I checked the Google Glass GDK, Mirror API and documentation on gestures.

A tap is detected as KeyEvent.KEYCODE_DPAD_CENTER

Is there any way to determine the position of the tap on the track pad?

Thank you.

You will need to subclass the Glass GestureDetector and override onMotionEvent(MotionEvent event) to capture the X_AXIS information. X increases as you tap closer to the front. 1000 is about at the front and 200 is towards the back. 

package foo;

import android.content.Context;
import android.view.MotionEvent;

import com.google.android.glass.touchpad.GestureDetector;

public class CustomGestureDetector extends GestureDetector {

    public CustomGestureDetector(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    @Override
    public boolean onMotionEvent(MotionEvent event) {
        // TODO Auto-generated method stub
        System.out.println(String.format("X: %.2f Y: %.2f", event.getAxisValue(MotionEvent.AXIS_X), event.getAxisValue(MotionEvent.AXIS_Y)));
        return super.onMotionEvent(event);
    }

}
