This invention is about a procedure and a system of operator interaction with tactile surface computers. The procedure/ system outlined by this invention are applicable to process computers equipped with touch screens. The system of operator interaction with tactile surface computers supporting the interaction procedure is made up of a screen (1) with a tactile surface (2) that are both connected to a computer (3). Data about the fmger touching the tactile surface (2) is scanned by a controller (5), which sorts out any hesitating gestures and turns them into plane (x,y) coordinates, which are then conveyed to the computer (3). There they are then taken over by a unit of primary data analysis (8), which determines when one sequence of (x,y) coordinates ends and when the other begins, depending on the time interval between two successive coordinates. If a gesture (11) is identified, its code is generated and a corresponding command (7) is executed by an execution/command unit (9). The execution of command (7) will lead to a change in computer (3) reflected in changed data on screen (1) or in changes in other units (10).
