Abstract:
1. A method comprising: receiving touch input to a first region of a surface of a touch sensitive device; selecting, in response to receiving the touch input to the first region, a first set of drive frequency values; outputting one or more first drive frequency signals, at frequencies based on the first set of drive frequency values, to respective one or more first haptic actuators included in a plurality of haptic actuators coupled to the surface of the touch sensitive device, the one or more first haptic actuators being located in proximity to the first region; receiving touch input to a second region of the touch sensitive device; selecting, in response to receiving the touch input to the second region, a second set of drive frequency values; and outputting one or more second drive frequency signals, at frequencies based on the second set of drive frequency values, to respective one or more second haptic actuators included in the plurality of haptic actuators coupled to the surface of the touch sensitive device, the one or more second haptic actuators being located in proximity to the second region,
