Abstract

The subject disclosure is directed towards a graphical or printed keyboard having keys removed, in which the removed keys are those made redundant by gesture input. For example, a graphical or printed keyboard may be the same overall size and have the same key sizes as other graphical or printed keyboards with no numeric keys, yet via the removed keys may fit numeric and alphabetic keys into the same footprint. Also described is having three or more characters per key, with a tap corresponding to one character, and different gestures on the key differentiating among the other characters.

Claims

1. A system comprising, a keyboard on a touch-sensitive surface at which tap input and gesture input is detected, the keyboard configured with a removed key set comprising at least one removed or substantially removed key, each key of the removed key set corresponding to a character that is enterable via a gesture.

2. The system of claim 1 further comprising logic coupled to the touch-sensitive surface to differentiate between taps and gestures.

3. The system of claim 1 wherein the removed key set comprises a removed shift key, a removed space key, a removed backspace key and a removed enter key.

4. The system of claim 1 wherein the removed key set comprises at least one of:

a removed shift key, a removed space key, a removed backspace key or a removed enter key.

5. The system of claim 1 wherein the removed key set comprises a shift key, and wherein a shifted key entry is detected via a gesture initiated on a non-shifted key corresponding to the shifted key entry.

6. The system of claim 1 wherein the keyboard includes a key representing three or more characters, and wherein at least two of the characters are entered and distinguished from one another via distinct gestures initiated on the key.

7. The system of claim 1 wherein the keyboard includes a key representing at least four characters, wherein a first character of the at least four characters is entered upon detecting a tap on the key, wherein a second character of the at least four characters is entered upon detecting an up and left gesture starting on the key, wherein a third character of the at least four characters is entered upon detecting a generally straight up gesture starting on the key, and wherein a fourth character of the at least four characters is entered upon detecting an up and right gesture starting on the key.

8. The system of claim 1 wherein the keyboard is further configured to provide a virtual touchpad input area that provides a plurality of cursor keys, or a pointer input region, or both a plurality of cursor keys and a pointer input region.

9. The system of claim 1 wherein the keyboard is further configured to provide a virtual touchpad input area that provides a plurality of cursor keys in one mode, and a pointer input region in another mode.

10. The system of claim 1 wherein the gesture input surface is divided into at least two regions including a first region and a second region, and wherein a gesture, if started in a first region, is assigned a different meaning from the same gestured if started in a second region.

11. The system of claim 10 wherein the gesture, if started in the first region is assigned a meaning comprising a key entry, and if started in the second region, is assigned a meaning comprising a command relating to an edit mode.

12. The system of claim 1 wherein a gesture made with two fingers, or made with one finger while another finger is pressing on the keyboard, has a different meaning from a similar gesture made with one finger.

13. The system of claim 1 wherein a gesture may be canceled or changed by reversing the gesture.

14. The system of claim 1 wherein the keyboard is implemented on a tablet computing device or a mobile phone device.

15. A method comprising, receiving data corresponding to interaction with a key of a keyboard comprising a plurality of keys, in which the key represents at least three characters, and if the data indicates that the interaction represents a first gesture, outputting a first character value, or if the data indicates that the interaction represents a second gesture that is different from the first gesture, outputting a second character value.

16. The method of claim 15 wherein if the data indicates that the interaction represents a tap, outputting tap-related character value represented by the key.

17. The method of claim 15 wherein if the data indicates that the interaction represents a third gesture that is different from the first gesture and the second gesture, outputting a third character value.

18. One or more computer-readable media having computer-executable instructions, which when executed perform steps, comprising, providing a graphical or printed keyboard, in which the graphical or printed keyboard includes alphabetic keys and numeric keys in a same-sized or substantially same-sized screen area relative to a different graphical or printed keyboard that includes alphabetic keys and does not include numeric keys, and in which the graphical or printed keyboard and the different graphical or printed keyboard have same-sized or substantially same-sized alphabetic keys, including by removing one or more keys from the graphical or printed keyboard that are made redundant by gesture input.

19. The one or more computer-readable media of claim 18 wherein removing the one or more keys from the graphical or printed keyboard that are made redundant by gesture input comprises removing at least one of:

a space key, an enter key, a shift key, or a backspace key.

20. The one or more computer-readable media of claim 18 having further computer executable instructions comprising, representing at least four characters on a single key of the graphical or printed keyboard, and outputting the first character entry, the second character entry, the third character entry or the fourth character entry, by processing tap input on the single key to differentiate the first character entry from among the at least four characters represented, or processing different gesture input starting on the single key to differentiate the second, third or fourth character entries from among the at least four characters represented.
