Systems and methods for inputting data using multi-character keys
View Patent ↗Systems and methods are provided for inputting data to a mobile device using multi-character keys. A first input may be generated by pressing a multi-character key on the mobile device. In response to the first input, the mobile device may sequentially display a plurality of characters associated with the pressed multi-character key. When a desired character is displayed, a second input may be generated to select the currently displayed character as character data input.
1. A method for inputting character data to an electronic device that includes a keyboard having a plurality of multi-character keys, comprising:
sequentially displaying, one character at a time, characters associated with a first multi-character key in response to the first multi-character key being pressed and released; and
selecting a displayed character in response to a second key being pressed.
2. The method of claim 1 wherein the first multi-character key and the second key are the same key.
3. The method of claim 1 wherein the first multi-character key and the second key are different keys with the second key being a dedicated key.
4. The method of claim 1 wherein the sequentially displaying characters associated with the first multi-character key is in response to a first switch being activated in response to the first multi-character key being pressed and selecting the displayed character is in response to a second switch being activated in response to the second key being pressed.
5. The method of claim 4 wherein the first switch is activated by partially depressing the first multi-character key and the second switch is activated by completely depressing the second key.
6. The method of claim 1 wherein the sequentially displaying characters associated with the first multi-character key are displayed in accordance with a display rate.
7. The method of claim 6 further comprising adjusting the display rate for sequentially displaying characters associated with the first multi-character key in response to receiving an input from an auxiliary input device.
8. The method of claim 1 wherein the sequentially displayed characters associated with the first multi-character key are displayed one at a time in an alphabetic sequence.
9. The method of claim 1 wherein the sequentially displayed characters associated with the first multi-character key further are displayed one at a time in an alphabetic sequence including capital and lower case characters.
10. An electronic device, comprising:
a keyboard comprising a plurality of multi-character keys;
a display; and
computer instructions stored on one or more non-transitory memory devices and executable by one or more processing devices in the electronic device, when executed the computer instructions being operable to:
sequentially display, one character at a time, characters associated with a first multi-character key in response to the first multi-character key being pressed and released; and
select a displayed character in response to a second key being pressed.
11. The electronic device of claim 10 wherein the first multi-character key and the second key are the same key.
12. The electronic device of claim 10 wherein the first multi-character key and the second key are different keys with the second key being a dedicated key.
13. The electronic device of claim 10 wherein each multi-character key includes a first switch and a second switch, and wherein the sequentially display, one character at a time, characters associated with a first multi-character key is in response to pressing the first multi-character key to activate the first switch and the select the displayed character is in response to pressing the second key to active the second switch.
14. The electronic device of claim 13 wherein the first switch is activated by partially depressing the first multi-character key and the second switch is activated by completely depressing the second key.
15. The electronic device of claim 10 wherein the sequentially displaying characters associated with the first multi-character key are displayed in accordance with a display rate.
16. The electronic device of claim 15 further comprising adjusting the display rate for sequentially displaying characters associated with the first multi-character key in response to receiving an input from an auxiliary input device.
17. The electronic device of claim 10 wherein the sequentially displayed characters associated with the first multi-character key are displayed one at a time in an alphabetic sequence.
18. The method of claim 1 wherein the sequentially displayed characters associated with the first multi-character key are displayed one at a time in an alphabetic sequence including capital and lower case characters.
19. A electronic device, comprising:
means for sequentially displaying, one character at a time, characters associated with a first multi-character key in response to the first multi-character key being pressed and released; and
means for selecting a displayed character in response to a second key being pressed.
20. The electronic device of claim 19 wherein the first multi-character key and the second key are the same key.
21. The electronic device of claim 19 wherein the first multi-character key and the second key are different keys with the second key being a dedicated key.
