Abstract

A system that produces a haptic effect and generates a drive signal that includes at least two haptic effect signals each having a priority level. The haptic effect is a combination of the haptic effect signals and priority levels. The haptic effect may optionally be a combination of the two haptic effect signals if the priority levels are the same, otherwise only the haptic effect signal with the highest priority is used. The frequency of haptic notifications may also be used to generate a drive signal using foreground and background haptic effect channels depending on whether the frequency ratio exceeds a foreground haptic effect threshold.

Claims

1. A method of producing a haptic effect comprising:

receiving a first input signal from a virtual simulation or animation;

receiving a second input signal from the virtual simulation or animation;

if the second input signal has a lower priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of perception;

if the second input signal has a higher priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of attention break-in;

applying a drive signal to a haptic output device according to the dynamic interaction parameter allowing a user to distinguish between the first input signal and the second input signal.

2. The method of claim 1, wherein determining the haptic level comprises using a signal component selected from the list consisting of strength, frequency, duration, rhythm, or dynamics.

3. The method of claim 1, wherein the first input signal or the second input signal comprises feedback originating from a local device.

4. The method of claim 1, wherein the first input signal or the second input signal comprises feedback originating from a primary user.

5. The method of claim 1, wherein the first input signal or the second input signal comprises feedback originating from another user.

6. The method of claim 1, wherein the haptic level comprises a defined or adaptive set of haptic effects.

7. The method of claim 1, wherein the threshold of perception comprises a natural or gradual foregrounding threshold.

8. The method of claim 1, wherein the threshold of perception comprises a non-distracting or “

polite”

threshold.

9. The method of claim 1, wherein the threshold of attention break-in comprises a threshold of pain.

10. The method of claim 1, wherein a virtual simulation or animation comprises a multi-tasking application.

11. A haptic effect enabled device comprising:

a haptic output device;

a drive module electronically coupled to the haptic output device for receiving a first input signal from a virtual simulation or animation, and receiving a second input signal from the virtual simulation or animation, and if the second input signal has a lower priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of perception, and if the second input signal has a higher priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of attention break-in; and

a drive circuit electronically coupled to the drive module and the haptic output device for applying a drive signal to a haptic output device on the device according to the dynamic interaction parameter allowing a user to distinguish between the first input signal and the second input signal.

12. The system of claim 11, wherein the drive module comprises a drive module for determining the first haptic level or the second haptic level comprises using a signal component selected from the list consisting of strength, frequency, duration, rhythm, or dynamics.

13. The system of claim 11, wherein the first input signal or the second input signal comprises feedback originating from a local device.

14. The system of claim 11, wherein the first input signal or the second input signal comprises feedback originating from a primary user.

15. The system of claim 11, wherein the first input signal or the second input signal comprises feedback originating from another user.

16. The system of claim 11, wherein the haptic level comprises a defined or adaptive set of haptic effects.

17. The system of claim 11, wherein the threshold of perception comprises a natural or gradual foregrounding threshold.

18. The system of claim 11, wherein the threshold of perception comprises a non-distracting or “

polite”

threshold.

19. The system of claim 11, wherein the threshold of attention break-in comprises a threshold of pain.

20. The system of claim 11, wherein a virtual simulation or animation comprises a multi-tasking application.

21. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, causes the processor to produce a haptic effect, the instructions comprising:

receiving a first input signal from a virtual simulation or animation;

receiving a second input signal from the virtual simulation or animation;

if the second input signal has a lower priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of perception;

if the second input signal has a higher priority than the first input signal, generating a dynamic interaction parameter using the first input signal, the second input signal, and a haptic level corresponding to a threshold of attention break-in;

applying a drive signal to a haptic output device according to the dynamic interaction parameter allowing a user to distinguish between the first input signal and the second input signal.

22. The non-transitory computer readable medium of claim 21, wherein determining the haptic level comprises using a signal component selected from the list consisting of strength, frequency, duration, rhythm, or dynamics.

23. The non-transitory computer readable medium of claim 21, wherein the first input signal or the second input signal comprises feedback originating from a local device.
