Abstract
A system that generates a haptic effect using an Eccentric Rotating Mass (“ERM”) actuator determines a vibration level of the device during operation of the device. The system receives a haptic effect signal including one or more parameters, where one of the parameters is a voltage amplitude level as a function of time. The system varies the voltage amplitude level based at least on vibration level and applies the varied haptic effect signal to the ERM actuator.
