Abstract

A method, apparatus and computer program product are provided for facilitating data entry into an electronic device via a touchscreen. As a user places his or her finger on the touchscreen, a cursor may be displayed at a location relative to other items displayed on the touchscreen that is proximate the physical location where the user touched the touchscreen. Because the cursor is likely now obscured by the user'"'"'s finger, the items displayed on the touchscreen, including the cursor, may then be shifted or scrolled so that the cursor is offset from the physical location where the user touched the touchscreen. At the same time, the items displayed on the touchscreen may be magnified in order to further facilitate data entry. At this point, the user may shift or tilt his or her finger in order to achieve the desired cursor placement.
