Abstract

A mobile terminal includes a housing, a first user interface located on a first face of the housing, a second user interface located on a second face of the housing different from the first face, and a controller within the housing and coupled to the first and second user interfaces. The second user interface includes a touch sensor configured to be used in tandem with the first user interface. The second user interface is positioned on the housing relative to the first user interface such that, when the mobile terminal is held in the user'"'"'s hand, the first user interface is operable by a thumb and the second user interface is operable by a finger of the same hand. The first user interface is configured to receive a first user input, and the second user interface is configured to receive a second user input. The controller is configured to detect a combination of the received first and second user inputs, and is configured to perform a mobile terminal function associated with the detected combination responsive to detection of the combination. Related user interfaces and methods of operation are also discussed.

a controller within the housing and coupled to the first and second user interfaces, wherein the controller is configured to detect a combination of the received first and second user inputs and perform a mobile terminal function associated with the detected combination responsive to detecting the combination.

2. The mobile terminal of claim 1, wherein the second face comprises a back of the mobile terminal housing configured to face away from a user during operation of the mobile terminal.

3. The mobile terminal of claim 2, wherein the first face comprises a front of the mobile terminal housing opposite the back and configured to face toward the user during operation of the mobile terminal.

4. The mobile terminal of claim 1, wherein the second user interface comprises a secondary interface, and wherein the controller is configured to only perform mobile terminal functions responsive to detecting a combination including the first user input.

5. The mobile terminal of claim 1, wherein the controller is configured to detect the combination based on first and second user inputs that are received substantially concurrently via the first and second user interfaces, respectively.

6. The mobile terminal of claim 1, wherein the first user interface comprises a keypad configured to detect depression of a button thereof as the first user input.

7. The mobile terminal of claim 1, wherein the first user interface comprises a second touch sensor configured to detect at least one touch and/or direction of motion thereon as the first user input.

8. The mobile terminal of claim 1, wherein the first user interface includes at least one physical and/or virtual button thereon including at least two alphanumeric characters and/or symbols associated therewith, and wherein:

the controller is configured to enter a first one of the associated characters and/or symbols responsive to detecting activation of the button on the first user interface as the first user input; and

the controller is configured to enter a second one of the associated characters and/or symbols responsive to detecting activation of the button on the first user interface as the first user input in combination with detecting at least one touch and/or direction of motion on the second user interface as the second user input.

9. The mobile terminal of claim 8, wherein the button includes at least three alphanumeric characters and/or symbols associated therewith, and wherein:

the controller is configured to enter the second one of the associated characters and/or symbols responsive to detecting activation of the button on the first user interface as the first user input in combination with detecting a first direction of motion in on the second user interface as the second user input; and

the controller is configured to enter a third one of the associated characters and/or symbols responsive to detecting activation of the button on the first user interface as the first user input in combination with detecting a second direction of motion different from the first direction on the second user interface as the second user input.

10. The mobile terminal of claim 1, wherein the controller is configured to determine a handedness of the user and perform the function responsive to detection of a different combination of the first and second user inputs based on the handedness of the user.

11. A method of operating a handheld mobile terminal, the method comprising:

receiving a first user input via a first user interface located on a first face of a mobile terminal housing;

receiving a second user input via a second user interface located on a second face of the mobile terminal housing different from the first face, the second user interface comprising a touch sensor configured to be used in tandem with the first user interface, wherein the second user interface is positioned on the housing relative to the first user interface such that, when the mobile terminal is held in the user'"'"'s hand, the first user interface is operable by a thumb and the second user interface is operable by a finger of the same hand to enable one-handed operation of the mobile terminal;

detecting a combination of the received first and second user inputs; and

performing a mobile terminal function associated with the detected combination responsive to detecting the combination.

12. The method of claim 11, further comprising the following when the mobile terminal is held in the user'"'"'s hand:

operating the first user interface with the thumb of the user'"'"'s hand to provide the first user input; and

operating the second user interface with the finger of the same hand to provide the second user input and enable one-handed operation of the mobile terminal.

13. The method of claim 12, wherein the second face comprises a back of the mobile terminal housing configured to face away from a user during mobile terminal operation.

14. The method of claim 13, wherein the first face comprises a front of the mobile terminal housing opposite the back and configured to face toward the user during mobile terminal operation.

15. The method of claim 11, wherein performing the mobile terminal function further comprises:

performing no mobile terminal functions responsive to receiving the second user input without receiving the first user input.

16. The method of claim 11, wherein detecting the combination of the first and second user inputs comprises:
