Abstract
A system and method for detecting at least two-finger input on a touch screen of a display such as computer, etc. includes a display screen; a sensing grid arranged for sensing touch on said display screen; a plurality of electrodes connected electrically to the sensing grid. A controller receives an output from the sensing grid, and a module identifies at least two points on the grid indicating locations of the display screen that have been touched by a user and identifies a geographic portion of the display screen to be identified based on said at least two points. As the position of the fingers are relative to the position of the screen via change in a direction of a Z-coordinate, a variable zoom can be provided by the sensing grid commensurate with different distances that the multiple fingers are sensed from the display screen.
