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.
