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 is:

1. A system comprising:
a processor;
a memory device that includes instructions executable by the processor to cause the processor to:
determine a game event; and
transmit a haptic signal based on the game event; and

a haptic output device communicatively coupled to the processor, the 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 plane being different from the first plane;

wherein the haptic output device is configured to output, based on the haptic signal, a haptic effect 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 a game controller.

3. The system of claim 2 , wherein the processor and memory device are positioned in a game system that is remote from the game controller.

4. The system of claim 2 , wherein the haptic output device is positioned on a joystick, a trigger, or a button of the game controller.

5. The system of claim 1 , wherein the haptic effect is configured to simulate movement or fluid flow in a video game.

6. The system of claim 1 , wherein the haptic output device further comprises a housing formed from an insulator material, and wherein an electrode in the first set of electrodes or the second set of electrodes comprises a deposited carbon nanotube.

7. Wherein the first panel is substantially parallel to the second panel.

8. The system of claim 1 , further comprising a sensor configured to detect a contact between a surface of the haptic output device and an object and transmit a sensor signal associated with the contact.

9. The system of claim 8 , wherein the memory device further includes instructions executable by the processor to cause the processor to:
receive the sensor signal from the sensor; and
generate the haptic signal based at least in part on the contact.

10. The system of claim 1 , wherein the haptic effect comprises: a change in a perceived coefficient of friction, a stroking sensation, a simulated texture, or a simulated vibration.

11. The system of claim 1 , wherein the haptic output device is flexible.

12. The system of claim 1 , wherein the memory device further includes instructions executable by the processor to cause the processor to:
determine a non-electrostatic force (ESF)-based haptic effect; and
transmit a second haptic signal associated with the non-ESF-based haptic effect to a second haptic output device, the second haptic output device being configured to receive the second haptic signal and output the non-ESF-based haptic effect.

13. A method comprising:
determining, by a processor, a game event;
transmitting, by the processor, a haptic signal to a haptic output device based on the game event, 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 plane being different from the first plane; and

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

14. The method of claim 13 , wherein the haptic output device is positioned on a game controller.

15. The method of claim 14 , wherein the haptic output device is positioned on a joystick, a trigger, or a button of the game controller.

16. The method of claim 13 , wherein the first panel is substantially parallel to the second panel.

17. A haptic output device comprising:
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 plane being different from the first plane;
wherein the haptic output device is configured to output, based on a haptic signal from a processor, a haptic effect 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.

18. The a haptic output device of claim 17 , wherein the haptic output device is positioned on a game controller or a wearable device.

19. The haptic output device of claim 18 , wherein the haptic output device is positioned on joystick, a trigger, or a button of the game controller.

20. The haptic output device of claim 17 , wherein the first panel is substantially parallel to the second panel.
