Claim:
1. An electronic device, comprising: a processing unit; a memory; and a haptic actuator; wherein the memory is operative to store instructions for generating a plurality of input waveforms to drive the haptic actuator; the haptic actuator is operative to move in response to the plurality of input waveforms applied to the haptic actuator; each input waveform is operative to cause the haptic actuator to move differently than other input waveforms in the plurality of input waveforms when applied as input to the haptic actuator in response to an instruction received by the processing unit; and the processing unit is operative to apply different combinations of the plurality of input waveforms to the haptic actuator for different alert conditions; and, at least one input waveform is formed from two or more discrete waveform components.
