Abstract

Products and processes for providing haptic feedback in a user interface are disclosed. One exemplary embodiment of an apparatus comprises a first element comprising a first surface, a second element comprising a second surface, and an actuator configured vary a force between the first and second surfaces. In one embodiment, the second element may be configured to be displaced relative to first element in a degree of freedom. In another embodiment, at least one of the first surface and the second surface may comprise a thermoplastic polymer.

Claims

1. An apparatus comprising:

a first element comprising a first surface;

a second element comprising a second surface and configured to be displaced relative to the first element in a degree of freedom, at least one of the first surface and the second surface comprising a thermoplastic polymer; and

an actuator configured to vary a force between the first surface and the second surface.

2. The apparatus of claim 1, further comprising a manipulandum coupled to at least one of the first element and the second element, wherein the actuator is operable to communicate a haptic effect through the manipulandum.

3. The apparatus of claim 2, wherein the manipulandum comprises one of:

a joystick, a knob, a scroll wheel, or a slider.

4. The apparatus of claim 1, wherein the degree of freedom comprises a rotary degree of freedom.

5. The apparatus of claim 1, wherein the force comprises a component substantially normal to the degree of freedom.

6. The apparatus of claim 1, further comprising a biasing element coupled to the actuator.

7. The apparatus of claim 1, further comprising a housing, wherein the housing is a housing of one of:

a mobile phone, a personal digital assistant, a camcorder, a control knob, a computer mice, or a joystick.

8. An apparatus comprising:

a magnetic target comprising a surface;

a magnetic core comprising a surface disposed in facing opposition to the surface of the magnetic target; and

a frictional element interposed between the surface of the magnetic target and the surface of the magnetic core, the frictional element comprising a thermoplastic polymer.

9. The apparatus of claim 8, wherein the frictional element comprises an acetal polymer.

10. The apparatus of claim 8, wherein the magnetic target comprises a transition metal alloy.

11. The apparatus of claim 8, wherein the magnetic target comprises a nickel-plated steel.

12. The apparatus of claim 8, wherein the frictional element is coupled with the magnetic target or the magnetic core.

13. The apparatus of claim 8, further comprising a manipulandum coupled to at least one of the magnetic target or the magnetic core.

15. The apparatus of claim 8, further comprising a housing, wherein the housing is a housing of one of:

a mobile phone, a personal digital assistant, a camcorder, a control knob, a computer mice, or a joystick.

14. The apparatus of claim 14, wherein the manipulandum comprises one of:

a joystick, a knob, a scroll wheel, or a slider.

16. A method comprising:

providing a magnetic target comprising a surface;

providing a magnetic core comprising a surface disposed in facing opposition to the surface of the magnetic target; and

interposing a frictional element between the surface of the magnetic target and the surface of the magnetic core, the frictional element comprising a thermoplastic polymer.

17. The method of claim 16, wherein the frictional element comprises an acetal polymer.

18. The method of claim 16, wherein the magnetic target comprises a transition metal alloy.

19. The method of claim 16, wherein the magnetic target comprises a nickel-plated steel.

20. The method of claim 16, wherein a distance between the surface of the magnetic target and the surface of the magnetic core comprises a range between approximately 0.0005 and approximately 0.0040 inches.

21. The method of claim 16, wherein the frictional element comprises a ring.

22. The method of claim 21, wherein the magnetic core comprises a first diameter and the frictional element comprises a second diameter, the first diameter greater than the second diameter.
