1. A method for operating a computer system having, a data processing unit;
- a touch-sensitive, position-resolving input surface which is a surface that is provided with sensors in such a manner that, as soon as it is touched by an object, it provides a sensor signal to said data processing unit which states that said surface is touched and said sensor signal contains the position coordinates of the point of contact; and
multiple freely movable input devices which are used to touch the input surface for the purpose of providing input to the data processing unit, each of said multiple freely movable input devices being a computer mouse which has a data connection to the data processing unit, the method comprising the steps of;
measuring with said touch-sensitive, position-resolving input surface the absolute position of points of contact on said touch-sensitive, position-resolving input surface and transmitting this absolute position information to said data processing unit;
and simultaneously measuring with each of said multiple freely movable input devices the relative position changes of said freely movable input device in that a relative shift with respect to a surface along which said freely movable input device is moved is measured in two coordinates and transmitting this relative position information of each of said multiple freely movable input devices to said data processing unit; and
comparing said absolute position information of each point of contact on said touch-sensitive, position-resolving input surface and said relative position information of each of said freely movable input devices with said data processing unit to identify which absolute position information of a point of contact correlates with the relative movement data of which freely movable input device thus identifying, which freely movable input device is located on which point of contact detected by said touch-sensitive, position-resolving input surface.

Abstract
A computer system that includes a data-processing unit, a touch-sensitive, position-resolving input surface in data communication with the data-processing unit, and a freely movable input device, by which the input surface is to be touched for the purpose of inputting into the data-processing unit. The freely movable input device is a computer mouse, which is in data communication with the data-processing unit. With comparatively low sensor complexity, inter alia, both the absolute position of the computer mouse and also subtle position changes of the computer mouse can therefore be very easily detected by the data-processing unit.
