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.

Claims

1. Apparatus and methods 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, substantially as shown and described.
