Abstract
A unique system and method is provided that facilitates pixel-accurate targeting with respect to multi-touch sensitive displays when selecting or viewing content with a cursor. In particular, the system and method can track dual inputs from a primary finger and a secondary finger, for example. The primary finger can control movement of the cursor while the secondary finger can adjust a control-display ratio of the screen. As a result, cursor steering and selection of an assistance mode can be performed at about the same time or concurrently. In addition, the system and method can stabilize a cursor position at a top middle point of a user's finger in order to mitigate clicking errors when making a selection.
