Abstract

The systems and methods described herein are used to edit haptic effects in real-time. At the outset, an animation object is received. A haptic effect is associated with the animation object, the haptic effect having a corresponding haptic drive signal. Subsequently, interpolation points are associated with the haptic drive signal along a timeline. One or more parameters of the haptic drive signal are adjusted between successive interpolation points to generate a modified haptic effect. While adjusting the parameters, the animation object and the modified haptic effects may be rendered.

Claims

1. A method for editing haptic effects, the method comprising:

retrieving an animation object;

associating a haptic effect with the animation object, the haptic effect having a corresponding haptic drive signal;

associating interpolation points with the haptic drive signal along a timeline;

adjusting one or more parameters of the haptic drive signal between successive interpolation points to generate a modified haptic effect; and

rendering the animation object and the modified haptic effects.

2. The method according to claim 1, wherein the animation object is based on motions of a user.

3. The method according to claim 1, wherein the haptic effect is a multi-frequency haptic effect that is rendered using a mono-frequency haptic output device.

4. The method according to claim 1, wherein the haptic effect is a texture haptic effect that is rendered by modifying multiple parameters of the haptic drive signal.

5. The method according to claim 1, wherein an envelope of the haptic drive signal is modified between successive control points of the haptic drive signal.

6. The method according to claim 1, wherein the parameters of the haptic drive signal are adjusted using a haptic library.

7. The method according to claim 1, wherein the parameters of the haptic drive signal are adjusted according to an event occurring within an application.

8. A non-transitory computer readable storage medium storing one or more programs configured to be executed by a processor, the one or more programs comprising instructions for:

retrieving an animation object;

associating a haptic effect with the animation object, the haptic effect having a corresponding haptic drive signal;

associating interpolation points with the haptic drive signal along a timeline;

adjusting one or more parameters of the haptic drive signal between successive interpolation points to generate a modified haptic effect; and

rendering the animation object and the modified haptic effects.

9. The non-transitory computer readable storage medium according to claim 8, wherein the animation object is based on motions of a user.

10. The non-transitory computer readable storage medium according to claim 8, wherein the haptic effect is a multi-frequency haptic effect that is rendered using a mono-frequency haptic output device.

11. The non-transitory computer readable storage medium according to claim 8, wherein the haptic effect is a texture haptic effect that is rendered by modifying multiple parameters of the haptic drive signal.

12. The non-transitory computer readable storage medium according to claim 8, wherein an envelope of the haptic drive signal is modified between successive control points of the haptic drive signal.

13. The non-transitory computer readable storage medium according to claim 8, wherein the parameters of the haptic drive signal are adjusted using a haptic library.

14. The non-transitory computer readable storage medium according to claim 8, wherein the parameters of the haptic drive signal are adjusted according to an event occurring within an application.

15. A device comprising:

a processor; and

a memory storing one or more programs for execution by the processor, the one or more programs including instructions for;

retrieving an animation object;

associating a haptic effect with the animation object, the haptic effect having a corresponding haptic drive signal;

associating interpolation points with the haptic drive signal along a timeline;

adjusting one or more parameters of the haptic drive signal between successive interpolation points to generate a modified haptic effect; and

rendering the animation object and the modified haptic effects.

16. The device according to claim 15, wherein the animation object is based on motions of a user.

17. The device according to claim 15, wherein the haptic effect is a multi-frequency haptic effect that is rendered using a mono-frequency haptic output device.

18. The device according to claim 15, wherein the haptic effect is a texture haptic effect that is rendered by modifying multiple parameters of the haptic drive signal.

19. The device according to claim 15, wherein an envelope of the haptic drive signal is modified between successive control points of the haptic drive signal.

20. The device according to claim 15, wherein the parameters of the haptic drive signal are adjusted using a haptic library.
