Abstract

One illustrative system disclosed herein includes a processor configured to determine an electrostatic force (ESF)-based haptic effect and transmit a haptic signal associated with the ESF-based haptic effect. The illustrative system also includes an ESF controller in communication with the processor, the ESF controller configured to receive the haptic signal, determine an ESF signal based at least in part on the haptic signal, and transmit the ESF signal. The illustrative system further includes a surface configured to contact a user, and an ESF device coupled to the surface and in communication with the ESF controller, the ESF device configured to receive the ESF signal and output the ESF-based haptic effect on the surface.

First claim

What is claimed:

1. A system comprising:
a processor;
a memory comprising program code that is executable by the processor to cause the processor to:
determine a haptic effect;
generate a haptic signal based on the haptic effect; and
transmit the haptic signal; and

a haptic output device including:
a first panel positioned in a first plane and having a first set of electrodes; and
a second panel positioned in a second plane and having a second set of electrodes, the second set of electrodes being positioned to slide relative to the first set of electrodes without contacting the first set of electrodes, the second plane being different from the first plane;

wherein the haptic output device is configured to receive the haptic signal and responsively output the haptic effect at least in part by generating an electrostatic coupling between the first set of electrodes and the second set of electrodes, the electrostatic coupling being configured to cause the first panel to slide laterally with respect to the second panel.

2. The system of claim 1 , wherein the haptic output device is positioned on an automotive dashboard.

3. The system of claim 1 , wherein the haptic output device is positioned on a steering wheel.

4. The system of claim 1 , wherein the haptic output device is positioned on a gear shifter.

5. The system of claim 1 , wherein the haptic output device is positioned on a mobile device.

6. The system of claim 1 , wherein the haptic output device is positioned on a wearable device.

7. The system of claim 1 , wherein the haptic effect comprises a sliding movement.

8. A method comprising:
receiving, by a haptic output device, a haptic signal from a processor, wherein the haptic output device includes:
a first panel positioned in a first plane and having a first set of electrodes; and
a second panel positioned in a second plane and having a second set of electrodes, the second set of electrodes being positioned to slide relative to the first set of electrodes without contacting the first set of electrodes, the second plane being different from the first plane; and

outputting, by the haptic output device, a haptic effect in response to receiving the haptic signal at least in part by generating an electrostatic coupling between the first set of electrodes and the second set of electrodes, wherein the electrostatic coupling causes the first panel to slide laterally with respect to the second panel.

9. The method of claim 8 , wherein the haptic output device is positioned on an automotive dashboard.

10. The method of claim 8 , wherein the haptic output device is positioned on a steering wheel.

11. The method of claim 8 , wherein the haptic output device is positioned on a gear shifter.

12. The method of claim 8 , wherein the haptic output device is positioned on a mobile device.

13. The method of claim 8 , wherein the haptic output device is positioned on a wearable device.

14. The method of claim 8 , further comprising:
transmitting, by a processor, the haptic signal in response to detecting a video game event, wherein the haptic effect is configured to simulate the video game event.

15. The method of claim 8 , wherein the haptic effect comprises a sliding movement.

16. A haptic output device including:
a first panel positioned in a first plane and having a first set of electrodes; and
a second panel positioned in a second plane and having a second set of electrodes, the second set of electrodes being positioned to slide relative to the first set of electrodes without contacting the first set of electrodes, the second plane being different from the first plane;
wherein the haptic output device is configured to receive a haptic signal and responsively output a haptic effect at least in part by generating an electrostatic coupling between the first set of electrodes and the second set of electrodes, the electrostatic coupling being configured to cause the first panel to slide laterally with respect to the second panel.

17. The haptic output device of claim 16 , wherein the haptic output device is positioned on an automotive dashboard, a steering wheel, or a gear shifter.

18. The haptic output device of claim 16 , wherein the haptic output device is positioned on a mobile device.

19. The haptic output device of claim 16 , wherein the haptic output device is positioned on a wearable device.

20. The haptic output device of claim 16 , wherein the haptic effect comprises a sliding movement.
