A directional input device for use in a handheld device is disclosed herein. The directional input device provides input to an element of the user interface in response to the inclination of the handheld. The input device can be embedded into any handheld communicating or computing device to provide directional input to an element of the user interface of the handheld without consuming space on the face of the device that could otherwise be used for a larger screen.

1. An input device within a mobile device for providing directional input in the mobile device in response to an inclination of the mobile device, the input device comprising: a primary contact positionally fixed in the mobile device;a plurality of directional contacts positionally fixed in the mobile device and operatively connected to the primary contact, each one of the plurality of directional contacts corresponding to a direction;a circuit closing element, the circuit closing element being in electrical contact with the primary contact, the circuit closing element being movable in response to inclination of the mobile device in the direction of at least one of the plurality of directional contacts, between a neutral position in which the primary contact and the at least one of the plurality of directional contacts form an open circuit, and an active position in which the primary contact and the at least one of the plurality of directional contacts form at least one closed circuit; anda direction interpreter, operatively connected to the primary and directional contacts; wherein when more than one closed circuit is formed, the direction interpreter generates a directional input corresponding to an average of each of the directions associated with each of the directional contacts in each of the closed circuits. 2. The input device of claim 1, wherein when only one closed circuit is formed, the direction interpreter generates a directional input corresponding to the direction associated with the directional contact of the closed circuit. 3. The input device of claim 1, wherein each of the plurality of directional contacts comprises a wall made of conductive material. 4. The input device of claim 3, wherein the plurality of directional contacts cooperatively enclose an area. 5. The input device of claim 4, further comprising a base, electrically connected to the primary contact, for supporting the circuit closing element. 6. The input device of claim 5, wherein the base corresponds to the area enclosed by the plurality of directional contacts. 7. The input device of claim 6, wherein the base biases the circuit closing element to the neutral position. 8. The input device of claim 7, wherein the circuit closing element is a ball bearing. 9. The input device of claim 7, wherein the circuit closing element is a mercury contact. 10. A mobile device, comprising: a display;a processor;a memory, the memory storing an operating system executed by the processor to display on the display a graphical user interface for controlling the operation of the mobile device, wherein the graphical user interface provides a graphical element responsive to a direction input signal processed by the processor;an internally-located directional input device comprising: a primary contact positionally fixed in the mobile device;a plurality of directional contacts positionally fixed in the mobile device and operatively connected to the primary contact, each one of the plurality of directional contacts corresponding to a direction;a circuit closing element, the circuit closing element being in electrical contact with the primary contact, the circuit closing element being movable in response to inclination of the mobile device in the direction of at least one of the plurality of directional contacts, between a neutral position in which the primary contact and the at least one of the plurality of directional contacts form an open circuit, and an active position in which the primary contact and the at least one of the plurality of directional contacts form at least one closed circuit; anda direction interpreter, operatively connected to the primary and directional contacts;wherein when more than one closed circuit is formed, the direction interpreter generates a directional input corresponding to an average of each of the directions associated with each of the directional contacts in each of the closed circuits; andwherein the processor causes the graphical element to move in response to the directional input. 11. The mobile device of claim 10, wherein when only one closed circuit is formed, the direction interpreter generates a directional input corresponding to the direction associated with the directional contact of the closed circuit. 12. The mobile device of claim 10, wherein each of the plurality of directional contacts comprises a wall made of conductive material. 13. The mobile device of claim 10, wherein the plurality of directional contacts cooperatively enclose an area. 14. The mobile device of claim 13, further comprising a base, electrically connected to the primary contact, for supporting the circuit closing element. 15. The mobile device of claim 14, wherein the base corresponds to the area enclosed by the plurality of directional contacts. 16. The mobile device of claim 15, wherein the base biases the circuit closing element to the neutral position. 17. The mobile device of claim 16, wherein the circuit closing element is a ball bearing. 18. The mobile device of claim 16, wherein the circuit closing element is a mercury contact.
