1. A method of mitigating locomotion of a device due to a haptic devices, the method comprising:
- activating the haptic device;
sensing movement of the device when the haptic device is activated;
determining, using a processor, if the device'"'"'s movement corresponds to a movement of the device across a surface due to the haptic device activation by determining if the movement exceeds a threshold distance; and
initiating a mitigation routine that reduces the movement of the device due to activation of the haptic device.

Abstract
One embodiment may take the form of a method of reducing noise from vibration of a device on a hard surface. The method includes activating a haptic device to indicate an alert and sensing an audible level during activation of the haptic device. Additionally, the method includes determining if the audible level exceeds a threshold and initiating mitigation routines to reduce the audible level to a level below the threshold if the threshold is exceeded.

8. A portable electronic device comprising:
-
a haptic actuator; a processor coupled to the haptic actuator, the processor configured to control the operation of the haptic actuator; one or more sensors configured to sense movement of the device, wherein the processor is configured to determine if movement of the device exceeds a threshold distance and is attributable to actuation of the haptic actuator, wherein the processor is further configured to implement a mitigation routine to reduce the movement based on the determination; and at least one acoustic sensor, wherein the processor is configured to determine if actuation of the haptic actuator generates sound at a level that exceeds a threshold and, if so, control the operation of the haptic actuator to reduce the sound to a level below the threshold. - View Dependent Claims (9, 10)

11. A method of mitigating of a device due to an actuation of a haptic device, the method comprising:
-
initiating an alert which activates the haptic device; sensing movement of the device when the haptic device is activated; determining, using a processor, if the device'"'"'s movement corresponds to a movement of the device across a surface due to the haptic device activation by determining if the movement exceeds a threshold distance; and initiating an alternative alert to reduce the movement of the device, wherein the alternative alert does not activate the haptic device. - View Dependent Claims (12, 13, 14)
