Key press disambiguation using a keypad of multidirectional keys
View Patent ↗Multidirectional keys of a reduced keypad are used to disambiguate between multiple symbols associated with a single key. For example, pressing a key identifies a collection of two or more symbols associated with the key and subsequently rocking the key selects one of the two or more symbols as unambiguously identified by the user.
1. A machine comprising:
a processor;
a memory operatively coupled to the processor; and
a data entry module (i) which executes in the processor from the memory and (ii) which, when executed by the processor, causes the machine to disambiguate among two or more symbols associated with a key of the machine by:
detecting a first type of actuation of the key;
in response to the detecting of the first type of actuation, displaying a representation of the two or more symbols;
detecting a second type of actuation of the key; and
selecting a selected one of the two or more symbols in accordance with the second type of actuation.
2. The machine readable medium of claim 1 wherein the first type of actuation includes pressing the key.
3. The machine readable medium of claim 2 wherein the second type of actuation includes rocking the key.
4. The machine readable medium of claim 1 wherein the key is a virtual key realized in a touch-sensitive device; and
further wherein the first type of actuation includes touching the virtual key within the touch-sensitive device.
5. The machine readable medium of claim 4 wherein the touch-sensitive device is a touch-sensitive screen.
6. The machine readable medium of claim 4 wherein the second type of actuation is a sliding along the touch-sensitive device.
7. The machine readable medium of claim 1 wherein selecting comprises:
navigating through the representation according to the second type of actuation of the key.
8. A method for disambiguating among two or more symbols associated with a key, the method comprising:
detecting a first type of actuation of the key;
in response to the detecting of the first type of actuation, displaying a representation of the two or more symbols;
detecting a second type of actuation of the key; and
selecting a selected one of the two or more symbols in accordance with the second type of actuation.
9. The method of claim 8 wherein selecting comprises:
navigating through the representation according to the second type of actuation of the key.
10. The method of claim 8 wherein the first type of actuation includes pressing the key.
11. The method of claim 10 wherein the second type of actuation includes rocking the key.
12. The method of claim 8 wherein the key is a virtual key realized in a touch-sensitive device; and
further wherein the first type of actuation includes touching the virtual key within the touch-sensitive device.
13. The method of claim 12 wherein the touch-sensitive device is a touch-sensitive screen.
14. The method of claim 12 wherein the second type of actuation is a sliding along the touch-sensitive device.
15. A machine readable medium useful in association with a machine which includes a processor and a memory, the machine readable medium including instructions which are configured to cause the machine to disambiguate among two or more symbols associated with a key of the machine by:
detecting a first type of actuation of the key;
in response to the detecting of the first type of actuation, displaying a representation of the two or more symbols;
detecting a second type of actuation of the key; and
selecting a selected one of the two or more symbols in accordance with the second type of actuation.
16. The machine readable medium of claim 15 wherein selecting comprises:
navigating through the representation according to the second type of actuation of the key.
17. The machine readable medium of claim 15 wherein the first type of actuation includes pressing the key.
18. The machine readable medium of claim 17 wherein the second type of actuation includes rocking the key.
19. The machine readable medium of claim 15 wherein the key is a virtual key realized in a touch-sensitive device; and
further wherein the first type of actuation includes touching the virtual key within the touch-sensitive device.
20. The machine readable medium of claim 19 wherein the touch-sensitive device is a touch-sensitive screen.
21. The machine readable medium of claim 19 wherein the second type of actuation is a sliding along the touch-sensitive device.
