I am creating a web app that I am wanting to be usable on mobile devices. The initial mechanic of said app requires the current X/Y coordinates of the mouse - which doesn't require clicking and dragging, just simply moving the mouse around a browser window.
Now I have been looking in to the various jQuery/Javascript libraries concerning Touch and Gestures, yet I am unable to find anything that suits what I am after.
So basically I am looking for a way to get the x/y pos of a single finger touch/drag.
Eg: Touch the screen at 0, 0 then hold and drag it to 480,320. The values would then interpolate between x1, y1 to x2, y2.
Thanks.
You shouldn't need a library for this, it's fairly easy to write your own code using the touchstart, touchmove and touchend events.

As a side note, if you're using the iOS simulator for testing, be aware that it can sometimes give incorrect coordinates in a way that an actual device wouldn't, so you'll always need to keep a physical iOS device handy to verify that your code works.
