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:

determining a first haptic level corresponding to a threshold of perception on a device;

determining a second haptic level corresponding to a threshold of attention break-in on the device;

receiving a first signal corresponding to a first task from a first application;

receiving a second signal corresponding to a second task from a second application;

if a priority of the first signal is greater than a priority of the second signal, generating a dynamic interaction parameter using the first signal, the second signal, and the first haptic level;

if the priority of the second signal is greater than the priority of the first signal, generating the dynamic interaction parameter using the first signal, the second signal, and the second haptic level;

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 task and the second task.

2. The method of claim 1, wherein 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.

3. The method of claim 1, wherein determining the first haptic level or the second haptic level comprises using a human factor selected from the list consisting of sensitivity to touch, how tightly a user may be holding the device, ambient temperature, age, physical activity, or environment.

4. The method of claim 1, wherein the first haptic level or the second haptic level 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.

5. The method of claim 1, wherein applying a drive signal comprises applying a drive signal to a haptic output device according to the dynamic 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.
