Abstract

A method and device for moving an indicator on an on-screen keyboard depicted on a display device is described. A series of signals transmitted from a remote-control unit are received at the display device. The indicator on a grid depicted on the display device is moved based on the received signals. A time for moving the indicator on the grid varies based on the series of signals received from the remote-control unit.

First claim

The invention claimed is:

1. A method, comprising:
receiving at a display device a series of signals transmitted from a remote-control unit, wherein the series of signals are generated by successive activations of keys on the remote-control unit;
analyzing a time for moving an indicator successive positions on a grid depicted on the display device based on the series of signals received from the remote-control unit; and
modifying said time and moving the indicator successive positions based on said modified time.

2. The method according to claim 1 , wherein the grid comprises at least one row and a plurality of columns or a plurality of rows and at least one column.

3. The method according to claim 1 , wherein the time for moving the indicator successive positions is based on the inverse of the time interval for moving the indicator between consecutive positions on the grid.

4. The method according to claim 3 , wherein
the time for moving the indicator successive positions is a first time, if a number of indicator moves is lower or equal to a first number of indicator moves; and
the time for moving the indicator successive positions is a second time, less than the first time, if the number of indicator moves is greater than the first number of indicator moves.

5. The method according to claim 1 , wherein the time is analyzed when the indicator is moved at least N successive positions in a first direction, with N≥2, followed by M successive positions in a second direction opposite to said first direction, with M=1 or M=2.

6. The method according to claim 5 , wherein the time is modified if at least two antagonist moves, P>2, are performed during a time period, D1, wherein said antagonist move comprises at least N successive positions in the first direction, with N≥2, followed by M successive positions in the second direction opposite to said first direction, with M=1 or M=2.

7. The method according to claim 6 , wherein if 2≤P≤4, and 10 s≤D1≤30 s, the time for moving the indicator successive positions on the grid is decreased.

8. The method according to claim 6 , wherein if P=0, and 40 s≤D1≤120 s, the time for moving the indicator successive positions on the grid is increased.

9. The method according to claim 1 , wherein said grid is one of:
an on-screen keyboard;
an on-screen menu; and
an on-screen list.

10. A device, comprising:
a receiver, configured to receive a series of signals transmitted from a remote-control unit, wherein the series of signals are generated by successive activations of keys on the remote-control unit; and
a processor, configured to:
analyze a time for moving an indicator successive positions on a grid depicted on a display device based on the series of signals received from the remote-control unit; and
modify said time and moving the indicator successive positions based on said modified time.

11. The device according to claim 10 , wherein the grid comprises at least one row and a plurality of columns or a plurality of rows and at least one column.

12. The device according to claim 11 , wherein the time for moving the indicator successive positions is based on the inverse of the time interval for moving the indicator between consecutive positions on the grid.

13. The device according to claim 12 , wherein
the time for moving the indicator successive positions is a first time, if a number of indicator moves is lower or equal to a first number of indicator moves; and
the time for moving the indicator successive positions is a second time, less than the first time, if the number of indicator moves is greater than the first number of indicator moves.

14. The device according to claim 10 , wherein the time is analyzed when the indicator is moved at least N successive positions in a first direction, with N≥2, followed by M successive positions in a second direction opposite to said first direction, with M=1 or M=2.

15. The device according to claim 14 , wherein the time is modified if at least two antagonist moves, P>2, are performed during a time period, D1, wherein said antagonist move comprises at least N successive positions in the first direction, with N≥2, followed by M successive positions in the second direction opposite to said first direction, with M=1 or M=2.

16. The device according to claim 15 , wherein if 2≤P≤4, and 10 s≤D1≤30 s, the time for moving the indicator successive positions on the grid is decreased.

17. The device according to claim 15 , wherein if P=0, and 40 s≤D1≤120 s, the time for moving the indicator successive positions on the grid is increased.

18. The device according to claim 10 , wherein said grid is one of:
an on-screen keyboard;
an on-screen menu; and
an on-screen list.

19. A system, comprising:
a remote-control unit; and
a device according to claim 10 .

20. A non-transitory computer-readable medium containing a program comprising a sequence of instructions for implementing a method according to claim 1 , when executed.
