The present invention may provide a device including a haptic driver to drive a coupled actuator causing the actuator to generate a vibratory haptic effect. A touch screen may display a user interface and may include a sensor to detect user interaction with the touch screen within a predetermined range above the touch screen. A controller may calculate a proximity event based on the detected user interaction above the touch screen, and to control haptic driver operations according to the proximity event.
