CLAIMS

1. A method for displaying a virtual keyboard layout to be used for typing a text on a mobile terminal (1 ), the method comprising:

- determining (a), by a processing unit (1 1 ) of the mobile terminal (1 ), a movement level of the mobile terminal (1 );

- selecting (b), by the processing unit (1 1 ), a virtual keyboard layout (VKLs), among a set of virtual keyboard layouts ({VKLj}je[ ;n]) displayable on a screen (13) of the mobile terminal, as a function of the determined movement level ; and

- displaying (c) the selected virtual keyboard layout (VKLS) on the screen (13).

2. A method according to claim 1 , wherein the selection of the virtual keyboard layout (VKLS) is performed among a set of virtual keyboard layouts ({VKI_i}ie[i ;n]) designed for the current display orientation mode of the screen (13).

3. A method according to claim 1 or 2, further comprising obtaining, by the processing unit (1 1 ), a pace indication of a user holding the mobile terminal (1 ), said movement level being determined as a function of the pace indication.

4. A method according to claim 3, further comprising receiving, by the processing unit (1 1 ), acceleration and/or angular velocity data from at least one sensor and calculating the pace indication from said data.

5. A method according to claim 3, further comprising receiving, by the processing unit (1 1 ), a step count from a pedometer connected to the mobile terminal (1 ) and calculating the pace indication from said step count.

6. A method according to any one of claims 1 to 5, wherein the movement level is selected among a plurality of predetermined movement levels, each predetermined movement level being associated to a virtual keyboard layout (VKL,) of said set ({VKLj}je[ ;n]), the virtual keyboard layout selected (VKLS) at step (b) being the virtual keyboard layout (VKL,) associated with the movement level determined at step (a).

7. A method according to one of claims 3 to 5 in combination with claim 6, wherein the predetermined movement levels are defined by threshold values of pace indication, the method further comprising comparing the obtained pace indication of the user holding the mobile terminal (1 ) with said threshold values.

8. A method according to any one of claims 6 and 7, wherein the more a predetermined movement level is associated with a fast user's movement, the larger is a size of keys of the virtual keyboard layout (VKL,) associated to this predetermined movement level.

9. A method according to any one of claims 1 to 8, wherein said set of virtual keyboard layouts ({VKI_i}ie[i;n]) comprises at least a full-alphabetical layout and a ABC-9-key layout.

10. A method according to claim 9, wherein said set of virtual keyboard layouts ({VKLj}je[ ;n]) further comprises a single-key layout for voice input.

11. A mobile terminal (1 ) comprising a processing unit (1 1 ) and a screen (13), the processing unit (1 1 ) being configured to:

- determine a movement level of the mobile terminal (1 );

- select a virtual keyboard layout (VKLS), among a set of virtual keyboard layouts ({VKLi}ie[o;n]) displayable on a screen (13) of the mobile terminal, as a function of the determined movement level, for display by the screen (13).

12. A mobile terminal (1 ) according to claim 1 1 , wherein the processing unit (1 1 ) is further configured to perform the selection of the virtual keyboard layout (VKLS) among a set of virtual keyboard layouts ({VKI_i}ie[i;n]) designed for the current display orientation mode of the screen (13).

13. A computer program product, comprising code instructions for executing a method according to any one of claims 1 to 10 for displaying a virtual keyboard layout to be used for typing a text on a mobile terminal (1 ), when executed by a processing unit of a mobile terminal.

14. A computer-readable medium, on which is stored a computer program product comprising code instructions for executing a method according to any one of claims 1 to 10 for displaying a virtual keyboard layout to be used for typing a text on a mobile terminal (1 ).
