Abstract
A controller for a surface haptic device that generates haptic waveforms and a method of generating desired haptic waveforms on a touch interface having a substrate and one or more electrodes connected to a front surface of the substrate are disclosed. The controller has a signal generator and a low pass filter, and automatically determines an on/off state of each of one or more surface haptic actuators such that a low pass filtered version of the on/off state closely approximates a desired waveform.
