Abstract

A method (300) in an electronic device (100) having a touch sensitive display (102) for searching entries in a stored list includes presenting (302) a reference character set as reference character ranges on an A by B matrix (103) of touch sensitive keys (120,121,122,123,124,125). Upon actuating a touch sensitive key having a reference character range presented thereon, the touch sensitive keys (120,121,122,123,124,125) are reconfigured to present (306) a secondary reference character set having alphanumeric characters within the reference character range presented on the touch sensitive key prior to actuation. Upon actuating a touch sensitive key having an alphanumeric character presented thereon, the alphanumeric character is added (308) to a search string indicator (111). Soft keys (104,105) and a soft key identification line (106) may be used in conjunction with the A by B matrix (103).

Claims

1. A method in an electronic device having a touch sensitive user interface of searching entries in a stored list, comprising:

receiving, with one or more processors comprising instructions to implement the method, a search actuation from the touch sensitive user interface; and

presenting, on the touch sensitive user interface, a reference character set for the stored list as reference character ranges on a matrix of A.times.B touch sensitive keys;

wherein the reference character ranges are less or equal in number than A.times.B; and

wherein each reference character range is presented on a different key;

detecting, with the one or more processors, actuation of one key of the matrix of A.times.B touch sensitive keys; and

presenting, with the one or more processors, a secondary reference character set on the matrix of A.times.B touch sensitive keys, and

omitting presentation of reference characters from the secondary reference character set not corresponding to the at least one entry of the stored list;

wherein each reference character of the secondary reference character set is within a reference character range presented on the one key prior to actuation.

2. The method of claim 1, wherein A.times.B is six or fewer.

3. The method of claim 2, wherein the reference character ranges comprise at least A-F, G-L, M-R, S-X, and Y-@.

4. The method of claim 2, wherein the stored list comprises one of a contact list or a file list.

5. The method of claim 1, wherein the each reference character corresponds to at least one entry of the stored list.

6. The method of claim 1, wherein when the secondary reference character set comprises more than A.times.B reference characters, further comprising:

presenting a subset of the secondary reference character set on a subset of the matrix of A.times.B touch sensitive keys; and

presenting an indicator of additional characters on at least one key of the matrix of A.times.B touch sensitive keys.

7. The method of claim 1, further comprising:

detecting actuation of a key of the matrix of A.times.B touch sensitive keys having a reference character presented thereon; and

presenting the reference character in a search string indicator.

8. The method of claim 7, further comprising presenting at least some of the entries of the stored list adjacent to the matrix of A.times.B touch sensitive keys, the at least some of the entries of the stored list beginning with the reference character.

9. The method of claim 7, further comprising presenting fewer of the entries of the stored list than the at least some of the entries of the stored list as reference characters are added to the search string indicator.

10. The method of claim 9, wherein the presenting fewer of the entries continues until a user selection of one of the entries is detected, and further comprising presenting the user selection on a display of the electronic device.

11. The method of claim 7, further comprising:

again presenting the reference character set for the stored list as the reference character ranges on different keys of the matrix of A.times.B touch sensitive keys.

12. The method of claim 9, further comprising:

detecting additional actuations of keys of the matrix of A.times.B touch sensitive keys; and

presenting additional secondary reference character sets on the matrix of A.times.B touch sensitive keys, wherein each additional reference character of the additional secondary reference character sets is within an additional reference character range presented on the keys of the matrix of A.times.B touch sensitive keys prior to actuation.

13. The method of claim 12, further comprising:

presenting additional reference characters in the search string indicator upon actuation of reference character-keys having additional reference characters presented thereon.

14. The method of claim 1, further comprising:

presenting an approximation key adjacent to the matrix of A.times.B touch sensitive keys;

detecting actuation of the approximation key; and

presenting the entries of the stored list corresponding to alphanumeric characters presented in a search string indicator.

15. A wireless communication device, comprising:

a processor;

a contact list application, operable with the processor, configured to store contacts as entries in a stored list;

a touch sensitive display, operable with the processor, and configured to present a three-by-two matrix of touch sensitive keys on the touch sensitive display; and

a search module, operable with the processor and the contact list application to find a contact, and configured to present partitioned alphanumeric character ranges on the touch sensitive keys;

wherein when a user actuates a touch sensitive key, the search module is configured to present only alphanumeric characters both within a partitioned alphanumeric character range presented on the touch sensitive key prior to actuation by the user and corresponding to entries in the stored list along the three-by-two matrix of touch sensitive keys.

16. The wireless communication device of claim 15, wherein when a user additionally actuates an additional touch sensitive key, the search module is configured to present an alphanumeric character corresponding to the additional touch sensitive key in a search string of the contact list application.

17. The wireless communication device of claim 16, wherein the partitioned alphanumeric character ranges comprise A-F, G-L, M-R, S-X, Y-@, and 123.

18. In address book application operating in a communication device having a touch sensitive user interface, a method of selecting an entry using the touch sensitive user interface, comprising:

presenting, with one or more processors comprising instructions to implement the method, alphanumeric character ranges in a three-by-two matrix of touch sensitive keys on the touch sensitive user interface, wherein each alphanumeric character range is presented on a different touch sensitive key;

detecting, with the one or more processors, actuation of one of the touch sensitive keys;

presenting, with the one or more processors, alphanumeric characters on the touch sensitive keys, wherein each of the alphanumeric characters corresponds to both an alphanumeric character range presented on the one of the touch sensitive keys prior to actuation and at least one entry of a stored list of the address book application;

detecting actuation of another of the touch sensitive keys; and

presenting, with the one or more processors, an alphanumeric character presented on the another of the touch sensitive keys in a search string indicator.

19. The method of claim 18, further comprising, upon presenting the alphanumeric character in the search string indicator, again presenting alphanumeric character ranges in the three-by-two matrix of touch sensitive keys.
