You can use the built-in Ionic Gesture to track various touch event like : hold , tap , doubletap , drag , dragstart , dragend , dragup , dragdown , dragleft , dragright , swipe , swipeup , swipedown , swipeleft , swiperight , transform , transformstart , transformend , rotate , pinch , pinchin , pinchout , touch , release .

In your case, I think touchmove can be replaced with drag event. This event return the x, y for you.

This is how to use:

In your controller: Inject the $ionicGesture dependency.

myApp.controller('myCtrl', ['$ionicGesture', function($ionicGesture){
    $ionicGesture.on('drag', function (e) {
        //Your logic here.
        //You can use console.log(JSON.stringify(e, null, 2)) to check the object (x,y coors)
    })
}]);
