Patent ID: 7352365

Claim:
Computer input system device with a touch-sensitive input surface having a plurality of input surface regions, and a control unit which is coupled to the input surface, in each case a character comprising a letter, a number or some other control symbol, being assigned to a specific one of said plurality of input surface regions, characterized in that the touch-sensitive input surface is configured in the topography of a computer keyboard defined by two substantially continuously updated topographies consisting of a basic topography corresponding to the respective positions of the fingertips of the hands in a basic keyboard position and an assignment topography defining the arrangement of target pressure points comprising said plurality of input surface regions arranged in positions determined relative to the positions of said basic topography, wherein the control unit dynamically adapts the positions of said plurality of input surface regions assigned to the various characters during operation of the device in response to actual finger keystroke contacts with the input surface, and further wherein the control unit substantially continuously monitors the position of the user's hands relative to the basic topography such that any change in the basic topography by the control unit causes a corresponding change in the assignment topography of the computer keyboard.
