1. A method of generating haptic effects for a user of a haptically-enabled system, the method comprising:

  • generating a control signal configured to cause a haptic device to output a first haptic effect, wherein the first haptic effect is within a frequency range where changes in a frequency of a haptic effect are tactilely undetectable to the user;

    receiving a request to generate a second haptic effect having a higher frequency than the first haptic effect, wherein the haptic device comprises a rotating mass and the second haptic effect is within the frequency range; and

    modifying the control signal to cause the haptic device to output the second haptic effect using the rotating mass and to cause the haptic device to output an audio output using the rotating mass;

    wherein the first haptic effect and the second haptic effect as output by the haptic device are both within the frequency range, and the audio output is configured to cause the user to perceive the second haptic effect to comprise the higher frequency than the first haptic effect.
