1. An input device comprising:
- a touchscreen for entry of commands by touching an operating surface of the touchscreen or by pressing on the operating surface;
at least one essentially U-shaped spring mechanical connecting the touchscreen to a reference structure;
wherein the operating surface of the touchscreen and at least one essentially U-shaped spring extend generally in the same plane;
an actuator actuated by a control signal to cause physical movement of the touchscreen in at least one direction, wherein a frequency of the physical movement of the touchscreen is at least partially defined by the U-shaped springs; and
a control module to generate the control signal to control the actuator to cause physical movement of the touchscreen as a function of a speed of a touching movement over the operating surface or a quantity derived from this speed.

Abstract
An input device, especially for a vehicle, comprises a touchscreen to enter commands by touching an operating surface of the touchscreen or by pressing on the operating surface, an actuator to move the touchscreen in at least one direction, and a control module to control the actuator as a function of the speed of a touching movement over the operating surface.

16. An input device comprising:
-
a touchscreen for input of commands by touching an operating surface of the touchscreen or by pressing on the operating surface; at least one essentially U-shaped spring mechanical connecting the touchscreen to a reference structure; wherein the operating surface of the touchscreen and at least one essentially U-shaped spring extend generally in the same plane; an actuator actuated by a control signal to cause physical movement of the touchscreen in at least one direction, wherein a frequency of the physical movement of the touchscreen is at least partially defined by the U-shaped springs; and a control module to generate the control signal to control the actuator to cause physical movement of the touchscreen such that; a first supposed surface condition of the operating surface can be felt by one touching the operating surface on a first position; and a second supposed surface condition of the operating surface different than the first supposed surface condition can be felt by one touching the operating surface on a second position distinct from the first position; wherein the first and second supposed surface conditions differ from an actual surface condition of the operating surface.

17. An input device comprising:
-
a touchscreen for entry of a command by touching an operating surface of the touchscreen or by pressing on the operating surface; at least one essentially U-shaped spring mechanical connecting the touchscreen to a reference structure; wherein the operating surface of the touchscreen and at least one essentially U-shaped spring extend generally in the same plane; an actuator actuated by a control signal to cause physical movement of the touchscreen in at least one direction, wherein a frequency of the physical movement of the touchscreen is at least partially defined by the U-shaped springs; and an observer to determine a speed of a touching movement over the operating surface or a quantity derived from the speed, wherein the control signal causes physical movement of the touchscreen as a function of the speed or the quantity derived from the speed. - View Dependent Claims (18)
