Method for influencing movements of an electronically controlled machine or system in a manually controlled manner, comprising: manual operation of a proportional or quasi-analogue controlling input means (9, 9'), generating a temporal sequence of quasi-analogue setpoint values, particularly positional values, speed values or acceleration values for a control device or for a drive controller of at least one drive of the electronically controlled machine or system, which temporal sequence of quasi-analogue setpoint values is based on the instructions or entries made by an operator with respect to the quasi-analogue controlling input means (9, 9'), wherein an at least one-dimensionally resolving, touch-sensitive position detection sensor, particularly of a touchpad or touchscreen (12, 12') type, serves as the input means which is used for the continuous detection of a sweeping activation movement or of at least a single activation position within an activating surface of the touch-sensitive position detection sensor that can be evaluated electronically, and wherein a temporal sequence of specified or position values is determined with the aid of the touch-sensitive position detection sensor relative to the activation surface thereof and converted into a corresponding temporal sequence of setpoint values for the drive controller characterized in that a plate-like screen and/or foil is superimposed on the touch-sensitive position detection sensor, which screen is furnished with recesses and/or which foil is furnished with elevations that serve to facilitate positioning or haptic guidance of an operator's fingers with respect to the touch-sensitive position detection sensor. manual operation of a proportional or quasi-analogue controlling input means (9, 9'), generating a temporal sequence of quasi-analogue setpoint values, particularly positional values, speed values or acceleration values for a control device or for a drive controller of at least one drive of the electronically controlled machine or system, which temporal sequence of quasi-analogue setpoint values is based on the instructions or entries made by an operator with respect to the quasi-analogue controlling input means (9, 9'), wherein an at least one-dimensionally resolving, touch-sensitive position detection sensor, particularly of a touchpad or touchscreen (12, 12') type, serves as the input means which is used for the continuous detection of a sweeping activation movement or of at least a single activation position within an activating surface of the touch-sensitive position detection sensor that can be evaluated electronically, and wherein a temporal sequence of specified or position values is determined with the aid of the touch-sensitive position detection sensor relative to the activation surface thereof and converted into a corresponding temporal sequence of setpoint values for the drive controller a plate-like screen and/or foil is superimposed on the touch-sensitive position detection sensor, which screen is furnished with recesses and/or which foil is furnished with elevations that serve to facilitate positioning or haptic guidance of an operator's fingers with respect to the touch-sensitive position detection sensor.
