Abstract

Technologies are generally described for devices, methods, and programs for reducing key input errors. An example device includes a detector to determine characteristics of a detected input and an arbiter to reject the detected input that has characteristics of an input error.

Claims

1. A device, comprising:

a detector to determine characteristics of a detected touch input; and

an arbiter to reject the detected touch input that has characteristics of a key input error.

2. The device of claim 1, wherein the characteristics of a key input error include a simultaneous multi-touch input that does not include a touch input of a special function key.

3. The device of claim 1, wherein the characteristics of a key input error include a simultaneous multi-touch input that does not include a touch input of at least one of a “

shift”

key, a “

control”

key, an “

alt”

key, or a “

function”

key.

4. The device of claim 1, wherein the characteristics of a key input error include a continuous key input for a duration that exceeds a predetermined threshold limit.

5. The device of claim 1, wherein the characteristics of a key input error includes a continuous key input of a non-special function key for a duration that exceeds a predetermined threshold limit.

6. A computer-readable medium that stores one or more executable instructions that, when executed, cause one or more processors to:

receive a designation of a special function input;

determine whether a simultaneous multi-touch input includes the special function input; and

deny entry of a function or feature corresponding to the simultaneous multi-touch input when the determination is negative.

7. The computer-readable medium of claim 6, wherein the computer-readable medium and the one or more processors are hosted on a client device that is communicatively coupled to a standard keyboard of which the special function input is a key.

8. The computer-readable medium of claim 6, wherein the computer-readable medium and the one or more processors are hosted on a client device that includes a touch keyboard of which the special function input is a key.

9. The computer-readable medium of claim 6,

wherein the computer-readable medium and the one or more processors are hosted on a client device that includes a virtual keyboard, and

wherein further the multi-touch input includes a simultaneous input from two or more keys on the virtual keyboard.

10. The computer-readable medium of claim 8, wherein the special function input includes at least one of a “

shift”

key, a “

control”

key, an “

alt”

key, or a “

function”

key.

11. The computer-readable medium of claim 8, wherein the special function input includes a user-designated combination of keys.

12. The computer-readable medium of claim 6, wherein the computer-readable medium and the one or more processors are hosted on a client device that includes:

a virtual keyboard of which the special function input is a key, and

a touch input display.

13. The computer-readable medium of claim 6,

wherein the computer-readable medium and the one or more processors are hosted on a client device that includes a virtual keyboard and a touch input display, and

wherein further the multi-touch input includes an input from either of the virtual keyboard and the touch input display simultaneous with at least one other input from either of the virtual keyboard and the touch input display.

14. The computer-readable medium of claim 13, wherein the special function input includes at least one of a “

shift”

key, a “

control”

key, an “

alt”

key, or a “

function”

key.

15. The computer-readable medium of claim 13, wherein the special function input includes a user-designated combination of touch inputs.

16. A device, comprising:

a key input user interface to receive a key input from a user;

a detector to measure time from a detected start of the key input from the user;

an arbiter to reject a function corresponding to the key input from the user when an end of the key input has not been detected within a predetermined threshold amount of time.

17. The device of claim 16,

wherein the key input user interface is a virtual keyboard, and

wherein further the key input corresponds to physical contact with any key on the virtual keyboard that is not designated as a special function key.

18. The device of claim 16,

wherein the key input user interface is a standard keyboard, and

wherein further the key input corresponds to physical contact with any key on the standard keyboard that is not designated as a special function key.

19. The device of claim 17, wherein the special function key may be at least one of the “

shift”

key, the “

control”

key, the “

alt”

key, or the “

function”

key.

20. A computer-readable medium that stores one or more executable instructions that, when executed, cause one or more processors to:

detect a touch input;

time the touch input; and

reject the touch input after a predetermined amount of time has elapsed and an end to the touch input has not been detected.

21. The computer-readable medium of claim 20, wherein the special function key may be at least one of the “

shift”

key, the “

control”

key, the “

alt”

key, or the “

function”

key.
