Abstract

A handheld wireless communication device configured to send and receive text messages. The device is hand cradleable with a body configured to be held in one hand by an operator during text entry. A display is located on a front face of the body and upon which information is displayed to the operator during text entry. A key field is also located on the front face of the body and that includes a plurality of alphanumeric input keys and menu keys. A trackball navigation tool is located on the front face of the body. The alphanumeric input keys include several alphabetic keys with letters arranged in a traditional (QWERTY), but non-ITU Standard E.161 telephone letter layout. A microprocessor is provided that receives operator commands from the keys and the trackball navigation tool and which affects corresponding changes to the display based on user input.

Claims

1. A handheld wireless communication device configured to send and receive text messages, said device comprising:

a hand cradleable body configured to be held in one hand by an operator of said device during text entry;

a display located on a front face of said body and upon which information is displayed to the operator during text entry;

a key field located on the front face of said body, said key field being composed of a plurality of keys selected from a plurality of alphanumeric input keys and at least one menu key;

a navigation tool located on the front face of said body;

said alphanumeric input keys comprising a plurality of alphabetic keys having letters associated therewith and said letters, in a top row of said alphabetic keys, comprising in consecutive order the letters Q, W, E, R and T; and

a microprocessor configured to receive operator commands from said alphanumeric input keys, said menu keys and said navigation tool and to affect corresponding changes to the display,

wherein said at least one key of said key field that is positioned adjacent to said navigation tool is a menu key that upon actuation displays an available action menu on said display.

2. The handheld wireless communication device as recited in claim 1, wherein said letters associated with said alphabetic keys are arranged in a QWERTY layout.

3. The handheld wireless communication device as recited in claim 1, wherein said letters associated with said alphabetic keys are arranged in a reduced-QWERTY layout.

4. The handheld wireless communication device as recited in claim 1, wherein said letters associated with said alphabetic keys are arranged in a QWERTZ layout.

5. The handheld wireless communication device as recited in claim 1, wherein said alphanumeric input keys comprise numeric keys having numerals associated therewith and wherein said associated numerals are arranged in a telephone keypad layout.

6. The handheld wireless communication device as recited in claim 1, wherein said body is configured to be held in the hand of the operator with a long axis of said device substantially horizontally oriented during text entry.

7. The handheld wireless communication device as recited in claim 1, wherein said body is configured to be held in the hand of the operator with a long axis of said device substantially vertically oriented during text entry.

8. The handheld wireless communication device as recited in claim 7, wherein said display is located in an upper portion of the front face of said body during text entry, said key field is located in a lower portion of the front face of said body during text entry and said navigation tool is located substantially between said key field and said display.

9. The handheld wireless communication device as recited in claim 1, wherein said navigation tool is at least partially surrounded by said key field.

10. The handheld wireless communication device as recited in claim 1, wherein a majority of said navigation tool is surrounded by said key field.

11. The handheld wireless communication device as recited in claim 1, further comprising:

said handheld wireless communication device being configured to send and receive voice communications;

wherein at least one key of said key field is positioned adjacent to said navigation tool and said at least one key has a circular arc-shaped edge conformance fitting to a circular arc-shaped boundary about said navigation tool; and

two call keys oppositely and laterally flank said navigation tool, one of said two call keys being a call initiation key and the other being a call termination key.

23. The handheld wireless communication device as recited in claim 1, wherein said displayed available action menu is an extended menu.

12. A handheld wireless communication device configured to send and receive text messages, said device comprising:

a hand cradleable body configured to be held in one hand by an operator of said device during text entry;
