Abstract

A user input device is provided that permits multiple functions to be implemented in a confined space using key images defined by a reconfigurable backlight structure under automatic software control. The keypads change automatically depending on what the user is doing with the device. By selectively illuminating one of several key images at each key location, widely varying keypad functionality can be realized without increased the size of the keypad or the number of key locations.

Claims

1. A multimedia handset, comprising:

a cellular telephone subsystem;

a media player subsystem;

a display on the housing of the handset;

an information processor for controlling the cellular telephone subsystem, the media player subsystem and the display, the information processor comprising operating modes configuring the cellular telephone subsystem of the handset in a telephone mode, configuring the display in a navigation, menu or list mode, or configuring the media player subsystem of the handset in a media player mode; and

a reconfigurable keypad for generating multiple patterns in association with an array of keys responsive to the information processor in each of the operating modes for providing one of a numeric keypad state, a navigation keypad state, and a media player keypad state automatically generated with the operating modes of the information processor.

2. A multimedia handset as recited in claim 1, comprising a soft-key user input positioned relative to the display.

3. A multimedia handset as recited in claim 1, wherein the reconfigurable keypad comprises multiple patterns at least one of which is used for each of the operating modes.

4. A multimedia handset as recited in claim 3, wherein the multiple patterns comprise one or more light emitting elements.

5. A multimedia handset as recited in claim 3, wherein the multiple patterns comprise an EL panel.

6. A multimedia handset as recited in claim 3, wherein the multiple patterns are positioned atop the array of keys, each key comprising a switching element that may be activated by user contact with at least one of the multiple patterns.

7. A multimedia handset as recited in claim 6, wherein the switching elements comprise mechanical switches including a plurality of momentary switch elements, or mechanical popple elements.

8. A multimedia handset as recited in claim 6, wherein the switching elements comprise a twelve-key ITU standard telephone keypad, and at least one of the multiple patterns comprises a twelve-key ITU standard telephone keypad pattern.

9. A multimedia handset as recited in claim 8, wherein at least one of the multiple patterns comprises a navigation mode, up, down, left, right and select image.

10. A multimedia handset as recited in claim 8, wherein at least one of the multiple patterns comprises a media player operating pattern comprising control symbols for play, reverse, forward or pause.

11. A multimedia handset as recited in claim 9, comprising the navigation mode in combination with a media player operating pattern comprising control symbols for play, reverse, forward or pause.

12. A handset device, comprising:

a first communications subsystem;

a second player subsystem;

a display on the housing of the handset device;

an information processor for controlling the first subsystem, the second subsystem and the display, the information processor comprising operating modes configuring the first subsystem of the handset device in a first mode, configuring the second subsystem of the handset device in a second mode, or configuring the display in a navigation mode; and

a reconfigurable keypad for generating multiple patterns in association with an array of keys responsive to the information processor in each of the operating modes for providing one of a numeric keypad state, a media control keypad state, and a navigation keypad state automatically generated with the operating modes of the information processor.

13. A handset device as recited in claim 12, comprising a soft-key user input positioned relative to the display.

14. A handset device as recited in claim 12, wherein the reconfigurable keypad comprises multiple patterns at least one of which is used for each of the operating modes.

15. A handset device as recited in claim 14, wherein the multiple patterns comprise one or more light emitting elements.

16. A handset device as recited in claim 14, wherein the multiple patterns comprise an EL panel.

17. A handset device as recited in claim 14, wherein the multiple patterns are positioned atop the array of keys, each key comprising a switching element that may be activated by user contact with at least one of the multiple patterns.

18. A reconfigurable keypad for generating multiple patterns in association with an array of keys comprising:

an information processor;

a layer comprising a surface to act as keys; and

a sheet located atop said layer, said sheet comprising multiple patterns coordinated with said layer and in conjunction with the information processor for operating as a plurality of input for the information processor; and

a film of a predetermined level of tint color located atop said sheet, with said sheet having an associated color such that the film appears transparent to incident light, and such that the film appears opaque to ambient light.

19. A reconfigurable keypad as recited in claim 18, wherein said layer comprises compressible popples to act as keys, said sheet selectively illuminates one or more of a multiplicity of patterns in relation to the keys with light illuminated for said sheet being transmissive through said film.

20. A reconfigurable keypad as recited in claim 19, wherein said sheet comprises one or more EL panels.

21. A reconfigurable keypad method in a handset device having a display on its housing with the handset device being operable with a plurality of subsystems, the method comprising:

information processing controlling the plurality of subsystems and the display, the information processing including operating modes configuring a first of the plurality of subsystems in a first mode, configuring a second of the plurality of subsystems in a second mode, or configuring the display in a navigation, menu or list mode;

providing a reconfigurable keypad with an array of keys; and

generating multiple patterns in association with the array of keys responsive to the information processing step in each of the operating modes for providing one of a numeric keypad state, a media control keypad state, and a navigation keypad state automatically generated with the operating modes of the information processing step.

22. A reconfigurable keypad method as recited in claim 21, wherein the step of generating multiple patterns comprises generating multiple patterns at least one of which is used for each of the operating modes.

23. A reconfigurable keypad method as recited in claim 22, wherein the step of generating multiple patterns comprises selectively illuminating one or more of the multiple patterns in relation to the array of keys automatically with the information processing step responsive to the operating modes.
