9. The display method of claim 8, further comprising:

animating the icon.

10. The method according to claim 8, wherein after the displaying, the method further comprises:

receiving additional user contact at the input area; and

causing an application associated with the event to execute responsive to the additional user contact.

11. The method according to claim 1, further comprising:

simultaneously receiving the user contact on at least two discrete locations of the input area;

identifying that the user contact corresponds to at least two regions of the plurality of regions to define a selection request; and

selecting an identified item of the items responsive to the selection request.

12. The method according to claim 11, further comprising:

providing tactile feedback responsive to the selection request.

13. The method according to claim 1, further comprising:

causing an event to occur at the mobile terminal responsive to the user contact; and

displaying an icon representing the event using a plurality of the at least one light emitting device.

14. The method according to claim 1, further comprising:

outputting audio of an audio signal; and

displaying an image corresponding to the audio signal using a plurality of the at least one light emitting device.

15. The method according to claim 14, wherein the image includes one or more of strength of the audio signal as a function of frequency, and an animated equalizer image.

16. A portable device, comprising:

an input area for receiving user contact;

a touchpad associated with the input area and comprising a plurality of regions;

a display for displaying items;

at least one light emitting device, which is separate from the display, and which is proximately located to the input area; and

a control unit for providing light feedback to a user, wherein the control unit is configured to;

identify which region of the plurality of regions of the touchpad is associated with the user contact;

navigate items displayed on the display responsive to the user contact; and

activate the light emitting device responsive to the user contact.

17. The portable device according to claim 16, wherein one of the plurality of regions defines a navigational direction key region, wherein the control unit is further configured to:

navigate the items responsive to user contact with the navigational direction key region.

18. The portable device according to claim 16, wherein one of the plurality of regions defines a selection key region, wherein the control unit is further configured to:
