1. A method implemented by a portable computer device, the method comprising: detecting a touch input that from a position at least partially off of a touch-screen, crosses over an edge of the touch-screen, and progresses as an expanding contact region from the edge of the touch-screen toward approximately a center region of the touch-screen while the touch input remains in contact with the touch-screen; determining the expanding contact region as a touch pull-in gesture to initiate a display of a user interface component based on a direction variable, a start region position variable, and a motion rate variable for which data is ascertained from the detected touch input; and initiating a display of the user interface component at a location of the touch pull-in gesture where detected as the touch input on the touch-screen, the touch pull-in gesture giving the appearance that the user interface component is dragged onto the touch-screen in a direction of the touch-pull in gesture.
