Abstract

An input device is provided that includes a touch-sensitive surface, and an attachment structure for attaching the surface. The surface is assigned a plane, wherein the attachment structure is configured to allow a displacement of the surface along an axis perpendicular to the assigned plane. The surface can assume a first position and, by displacement, a second position that is different from the first.

Claims

1. An input device, comprising:

a touch-sensitive surface;

a guide rail attached to the touch sensitive surface,

wherein the surface is assigned to a plane,

wherein the guide rail is configured to allow a displacement of the surface by a user along an axis perpendicular to the assigned plane, whereby the surface assumes a first position and, via the displacement, a second position that is different from the first position; and

a force exerting device configured to exert forces on the surface parallel to the axis, said forces being perceivable at varying levels as a function of the position of the surface,

wherein the force exerting device is further configured to exert forces such that the surface remains in the first position without forces being exerted by a user on the surface and, in response to the displacement to the second position, remains in the second position without forces being exerted by the user on the surface.

2. The input device according to claim 1, further comprising:

a position sensor configured to detect and output whether the surface is in the first position or the second position.

3. The input device according to claim 1, wherein the force exerting device is one of an electric motor, a magnet and a solenoid.

4. The input device according to claim 3, wherein the force exerting device is configured to exert forces such that the surface does not remain in the first or second position without forces being exerted by the user.

5. The input device according to claim 1, wherein the force exerting device is configured to exert forces such that the surface does not remain in the first or second position without forces being exerted by the user.

6. The input device according to claim 5, wherein the force exerting device is configured to generate locking positions for the surface.

7. The input device according to claim 1, wherein the surface is displaceable parallel to the axis by a user by exerting perceptible forces on the surface.

8. The input device according to claim 1, wherein the touch-sensitive surface is configured to detect a position of touch inputs of a user on the surface, which are used to control the position of a pointer on a display.

9. A computer, comprising:

an input device comprising;

a touch-sensitive surface;

a guide rail attached to the touch sensitive surface,

wherein the surface is assigned to a plane, and

wherein the guide rail is configured to allow a displacement by a user of the surface along an axis perpendicular to the assigned plane, whereby the surface assumes a first position and, via the displacement, a second position that is different from the first position; and

a force exerting device configured to exert forces on the surface parallel to the axis, said forces being perceivable at varying levels as a function of the position of the surface, and wherein the force exerting device is further configured to exert forces such that the surface remains in the first position without forces being exerted by a user on the surface and, in response to the displacement to the second position, remains in the second position without forces being exerted by the user on the surface;

a position sensor, which is configured to detect and output whether the surface is in the first position or second position;

an electronic arithmetic unit; and

a display, which is configured to display a graphical user interface, wherein the user interface creates the impression for a user as if a first object were disposed spatially in front of a second object,

wherein the electronic arithmetic unit is configured to receive the position of the surface and associate the first position of the surface with the first object and associate the second position of the surface with the second object.

10. The computer according to claim 9, wherein the first position of the surface is in front of the second position of the surface for the user, or wherein the first position of the surface is behind the second position of the surface for the user.

11. The computer according to either claim 10, wherein the first object comprises an area, and the arithmetic unit is configured to receive the position of a touch of the surface and to associate the position of the touch with a position in the area of the first object.

12. The computer according to claim 11, wherein the area is a window.

13. The computer according to claim 11, wherein the display is an autostereoscopic display or a head-mounted display.

14. The computer according to claim 9, wherein the display is an autostereoscopic display or a head-mounted display.

15. The computer according to claim 9, wherein the force exerting device is one of an electric motor, a magnet and a solenoid.

16. The computer according to claim 9, wherein, wherein the force exerting device is configured to exert forces such that the surface does not remain in the first or second position without forces being exerted by the user.

17. The computer according to claim 16, wherein the force exerting device is configured to generate locking positions for the surface.
