Abstract: In some aspects, an electronic device may display a keyboard user interface on a touchscreen display panel. The electronic device may detect a key press interaction with the keyboard user interface. The electronic device may trigger one or more haptic actuators to generate a vibration waveform associated with a haptic pattern that is based at least in part on a context associated with the key press interaction. Numerous other aspects are described.

Abstract: Audio and haptic signal processing systems and methods are provided. There is provided a method for haptic drive signal generation. The method comprises receiving an input audio signal for driving an audio speaker. The method further comprises deriving, from the audio signal, data components indicative of behaviour of the audio speaker when being driven by the input audio signal, each data component being associated with a respective frequency range. The method further comprises determining a haptic drive component from each data component. A gain is selected to provide to each of the haptic drive components, the gain being selected for each respective frequency range. Each selected gain is applied to the respective haptic drive component to produce gain adjusted haptic drive components. A haptic drive signal is determined from the gain adjusted haptic drive components, the haptic drive signal being so as to produce a mechanical behaviour of the haptic actuator when the haptic drive signal is used to drive the haptic actuator
