Abstract

Described herein are systems and methods for interfacing a user with a touch-screen. In overview, some embodiments provide for an array of conventional numerical keys to be graphically represented as a primary menu on a touch-screen of a cellular phone or PDA. The graphically represented keys arranged as sectors or annular sectors in a contiguous array around a central origin. To provide text-based input (for example in the process of authoring a text-message or email), a user touch-selects one of the keys, and is provided with a secondary menu for allowing selection of a particular alphanumeric character associated with the selected numerical key. This association is optionally based on a protocol such as ETSI ETS 300 640 or ITU-T Recommendation E.161. In some embodiments the secondary menu, or a similar tertiary menu, is used to provide additional predictive text functionality.

Claims

1. A method for interfacing a user with a touch-screen, the method including the steps of:

(a) displaying on the touch-screen a representation of a substantially circular primary menu, the primary menu including a plurality of primary input regions arranged as sectors or annular sectors in a contiguous array, each primary input region being associated with a respective primary command, each primary input region displaying a representation indicative of its respective primary command;

(b) being responsive to a touch-selection of one of the primary input regions for identifying one or more secondary commands related to the primary command associated with the touch-selected primary input region;

(c) displaying on the touch-screen a representation of a secondary menu, the secondary menu radially extending substantially as an annular sector from the periphery of the primary menu substantially adjacent the touch-selected primary input region, the secondary menu including one or more secondary input regions, the one or more secondary input regions being respectively associated with the one or more secondary commands, each secondary input region displaying a representation indicative of its respective secondary command.

2. A method according to claim 1 wherein, for at least one primary input region, the representation is indicative of a plurality of distinct alphanumeric characters.

3. A method according to claim 2 wherein, for the at least one primary input region, the associated primary command is related to a plurality of secondary commands respectively corresponding to at least one of the distinct alphanumeric characters.

4. A method according to claim 3 wherein the relationship between primary and secondary commands is affected by the operation of a predictive text protocol, such that for the at least one primary input region, the associated primary command is relatable to a plurality of secondary commands respectively corresponding to predicted words.

5. A method according to claim 1 wherein the secondary menu shares a common origin with the primary menu.

6. A method according to claim 1 wherein the secondary menu has an angular divergence of between 50% and 200% of an angular divergence of the touch-selected primary input region.

7. A method according to claim 1 wherein the secondary menu has an angular divergence of between 100% and 150% of an angular divergence of the touch-selected primary input region.

8. A method according to claim 1 wherein the secondary menu has an angular divergence approximately equal to an angular divergence of the touch-selected primary input region.

9. A method according to claim 1 wherein, upon the secondary menu being displayed, the on-screen positioning of the primary and secondary menus varies.

10. A method according to claim 9 wherein the variation includes movement substantially along a vector defined by a central radius of the touch-selected primary input region having a direction towards an origin of the primary menu.

11. A method according to claim 1 wherein, upon the secondary menu being displayed, the on-screen scaling of the primary and secondary menus varies.

12. A method according to claim 1 wherein the primary input regions correspond to keys on a twelve-key telephone keypad.

13. A method according to claim 1 including the further steps of:

(d) being responsive to a touch-selection of one of the secondary input regions for inputting a character, symbol or word represented by that secondary input region;

(e) following step (d), closing the secondary menu.

14. A method according to claim 1 including the further steps of:

(f) being responsive to a touch-selection of one of the secondary input regions for identifying one or more tertiary commands related to the secondary command associated with the touch-selected secondary input region;

(g) displaying on the screen a representation of a tertiary menu, the tertiary menu radially extending substantially as an annular sector from the periphery of the secondary menu substantially adjacent the touch-selected secondary input region, the tertiary menu including one or more tertiary input regions, the one or more tertiary input regions being respectively associated with the one or more tertiary commands, each tertiary input region displaying a representation indicative of its respective tertiary command.

15. A method according to claim 14 including the steps of:

(h) being responsive to a touch-selection of one of the tertiary input regions for inputting a character, symbol or word represented by that tertiary input region;

(i) following step (h), closing the tertiary and secondary menus.

16. A method according to claim 1 including the steps of:

(j) being responsive to touch selection of a primary input region for identifying one or more predicted words on the basis of a predictive text protocol;

(k) providing in the secondary menu one or more secondary input regions each having an associated secondary command indicative of one of the predicted words, and displaying a representation indicative of that predicted word.

17. A method according to claim 16 including the steps of:

(l) being responsive to a touch-selection of one of the secondary input regions having an associated secondary command indicative of a predicted word for inputting that predicted word;

(m) following step (l), closing the secondary menu.

18. A method according to claim 1 including the steps of:

(n) being responsive to touch selection of a primary input region for identifying one or more predicted words on the basis of a predictive text protocol;

(o) displaying on the screen a representation of a tertiary menu, the tertiary menu radially extending substantially as an annular sector from the periphery of the secondary menu displayed at step (c), the tertiary menu including one or more tertiary input regions, the one or more tertiary input regions being respectively associated with one or more tertiary commands each respectively indicative of a predicted word, each tertiary input region displaying a representation indicative of its respective predicted word.

19. A method according to claim 18 including the steps of:

(p) being responsive to a touch-selection of one of the tertiary input regions having an associated tertiary command indicative of a predicted word for inputting that predicted word;

(q) following step (p), closing the tertiary and secondary menus.

23. A computer-readable carrier medium carrying a set of instructions that when executed by one or more processors cause the one or more processors to carry out a method according to any one claim 1.

24. A device including:

a touch-screen; and

a processor coupled to the touch-screen for carrying out a method according to claim 1.

20. A method for interfacing a user with a touch-screen, the method including the steps of:

(a) displaying on the touch-screen a representation of a substantially circular primary menu, the primary menu including a plurality of primary input regions arranged as sectors or annular sectors in a contiguous array, the primary input regions including a set of primary input regions that correspond to one or more keys on a 12-key telephone keypad;

(b) being responsive to a touch-selection of one of the primary input regions for identifying one or more characters related to the touch-selected primary input region;

(c) displaying on the touch-screen a representation of a secondary menu, the secondary menu radially extending substantially as an annular sector from the periphery of the primary menu substantially adjacent the touch-selected primary input region, the secondary menu including one or more secondary input regions, the one or more secondary input regions corresponding to the one or more characters related to the touch-selected primary input region.
