Abstract
Embodiments of the invention provide methods and apparatuses for updating the physical coordinates of logical keys of a virtual keyboard on a touch input system as a result of detecting and determining the drift of the user'"'"'s fingers that make touch contact with a touch-sensitive member of the touch input system to operate the logical keys. The logical keys are given coordinates at the moment fingers are placed on the virtual keyboard in a home-row position. As the user types on the virtual keyboard, the device detects any drift of the fingers from the home-row position and determines the distance and direction of the drift. The device recalibrates the touch-sensitive member by updating the physical coordinates of some or all of the other logical keys to reflect the drift of the fingers.
