A system and method may dynamically control and/or dynamically adjust haptic output based on a particular application or context within which the output is to be generated. This may allow for output of an appropriate level of vibratory, or haptic output, that is dynamically tailored, or dynamically adjusted, for the particular situation, or application, or context for which the output is generated. This may include a mode in which an output having a relatively high peak amplitude is desired or most effective for the particular situation, or application, or context, a mode in which a relatively large bandwidth is desired or most effective for the particular situation, or application, or context, and the like.

Dynamic bandwidth adjustment and electromagnetic damping

A method includes: receiving, in an electronic device having a trackpad, a force signal that a force sensor of the trackpad generates based on a user input at the trackpad; receiving, in the electronic device, a touch signal that a touch sensor of the trackpad generates based on the user input; selecting, by the electronic device and based on at least one of the force signal or the touch signal, a first driver signal waveform from among multiple driver signal waveforms applicable to an actuator coupled to the trackpad; scaling, by the electronic device, the first driver signal waveform into a second driver signal waveform, the scaling based on at least one of the force signal or the touch signal; and generating, by the electronic device, a haptic output in response to the user input by providing the second driver signal waveform to the actuator.

A method for performing a calibration process in an electronic device includes generating a drive signal from a haptic driver in a haptic system disposed in an electronic device, transmitting the drive signal to an actuator in the haptic system, detecting a back Electromotive Force (bEMF) signal from the actuator in the haptic system, analyzing an output waveform from the bEMF signal, and adjusting a scale of the drive signal generated from the haptic driver.

The controller can be configured to activate the texture haptics layer in response to an object moving along the cover, control an image presented by the display layer, and activate the impact haptics layer in response to the object contacting the cover.
