Abstract
A system that generates a haptic effect on a device using an Eccentric Rotating Mass ('ERM') actuator determines an acceleration of the device during operation of the device and receives a haptic effect signal including one or more parameters, where one of the parameters is a voltage output level. The system varies the voltage output level parameter based at least on determined acceleration, and applies the varied haptic effect signal to the ERM actuator.
