System and method for modifying haptic feedback response of a touch sensor

Abstract

One variation of a method for modifying haptic feedback response includes, during a set-up period: at a calibration system, applying a target selection force, to a target location on a surface of a touch sensor; at the touch sensor, triggering vibration cycles across haptic actuators to oscillate the touch sensor surface; capturing a haptic waveform representing oscillations at the first target location on the surface during the vibration cycles; interpreting a vibration cycle for the haptic actuators corresponding to a target haptic intensity at the target location based on the haptic waveform. The method also includes, during a deployment period, following the set-up period: detecting a force magnitude for a touch input applied proximal the target location on the surface; and in response to the force magnitude exceeding the target selection force, triggering the vibration cycle at the haptic actuators to oscillate the surface at the target haptic intensity.
