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 notification signal from a local device, the notification signal having a percentage completion value;

comparing the notification signal to a foreground haptic threshold;

if the percentage completion value is greater than or equal to the foreground haptic threshold, generating an interaction parameter using a foreground haptic effect signal corresponding to a primary task from a first application;

if the percentage completion value is less than the foreground haptic threshold, generating an interaction parameter using a background haptic effect signal corresponding to a non-primary task from a second application; and

applying a drive signal to a haptic output device according to the interaction parameter allowing a user to distinguish between the primary task and the non-primary task.

2. The method of claim 1, wherein the foreground haptic effect signal or the background haptic effect signal comprises a haptic effect signal selected from the list consisting of strength, frequency, duration, rhythm, dynamics, positive additive effect, negative subtractive effect, or change in effect.

3. The method of claim 1, wherein the foreground haptic effect signal or the background haptic effect signal comprises an adaptive set of static or dynamic haptic effects or effect components in response to user input, system input, device sensor input or ambient input.

4. The method of claim 1, wherein the notification signal from a local device comprises a notification signal selected from the list consisting of a local user, a primary user, or a remote user.

5. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device according to the interaction parameter concurrently with a visual display.

6. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a user to distinguish between different effects and identifying them as originating from different sources.

7. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a user to distinguish between virtual simulations or animations.

8. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a natural or gradual foregrounding of haptic effects.

9. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a non-distracting augmentation of haptic encoded content.

10. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device representing any type of input by any number of haptic events on one or more foreground or background haptic channels.

11. A haptic effect enabled system comprising:

a haptic output device;

a drive module electronically coupled to the haptic output device for receiving a notification signal from a local device, the notification signal having a percentage completion value, and comparing the notification signal to a foreground haptic threshold, and generating an interaction parameter using a first haptic effect signal combined with a first priority level and a second haptic effect signal combined with a second priority level; and

if the percentage completion value is greater than or equal to the foreground haptic threshold, generating an interaction parameter using a foreground haptic effect signal corresponding to a primary task from a first application; and

if the percentage completion value is less than the foreground haptic threshold, generating an interaction parameter using a background haptic effect signal corresponding to a non-primary task from a second application; and

a drive circuit electronically coupled to the drive module and the haptic output device for applying a drive signal to the haptic output device according to the interaction parameter allowing a user to distinguish between the primary task and the non-primary task.

12. The system of claim 11, wherein the foreground haptic effect signal or the background haptic effect signal comprises a haptic effect signal selected from the list consisting of strength, frequency, duration, rhythm, dynamics, positive additive effect, negative subtractive effect, or change in effect.

13. The system of claim 11, wherein the foreground haptic effect signal or the background haptic effect signal comprises an adaptive set of static or dynamic haptic effects or effect components in response to user input, system input, device sensor input or ambient input.

14. The system of claim 11, wherein the notification signal from a local device comprises a notification signal selected from the list consisting of a local user, a primary user, or a remote user.

15. The system of claim 11, wherein applying a drive signal comprises applying a drive signal to a haptic output device according to the interaction parameter concurrently with a visual display.

16. The system of claim 11, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a user to distinguish between different effects and identifying them as originating from different sources.

17. The system of claim 11, wherein applying a drive signal comprises applying a drive signal to a haptic output device providing a user to distinguish between virtual simulations or animations.
