Abstract

A method and device is for a multi-touch based correction of a handwriting sentence system. The method includes receiving touch inputs, generating interpreted input data as a function of the touch inputs, and displaying the interpreted input data on a display device. A request to correct a portion of the interpreted input data then switches to a correction mode. During the correction mode, a correction user interface is displayed on the display device, a gesture is received so setting data is determined as a function of a first disposition of the gesture, the setting data indicating a type of correction to be applied to the portion of the interpreted inputs, a correction data is determined as a function of a second disposition of the gesture, and the portion of the interpreted input data is corrected as a function of the touch input, the setting data, and the correction data.

Claims

1. An electronic device, comprising:

a touch sensitive display device configured to receive at least one touch input;

a processor generating interpreted inputs as a function of the touch inputs; and

a memory arrangement storing at least the at least one touch input and the interpreted inputs,

wherein the display device is further configured to show the interpreted inputs and to receive a request to correct at least a portion of the interpreted inputs, the processor switching to a correction mode,

wherein, during the correction mode, a correction user interface is displayed on at least a portion of the display device, a gesture being received via the correction user interface, further wherein the gesture is a multi-touch input comprising a multi-finger gesture, and

wherein the processor determines a setting data as a function of a first disposition of the multi-finger gesture, the setting data indicating a portion of the interpreted inputs to which one of a set of types of correction is to be applied, the processor further determining a correction data as a function of a second disposition of the multi-finger gesture so that the portion of the interpreted inputs is corrected as a function of the at least one touch input, the setting data, and the correction data, wherein the set of types of correction comprises;

a separation to correct a split-over combination error; and

a combination to correct a combine-over segmentation error.

2. The electronic device of claim 1, wherein the separation is identified via a two-finger gesture wherein each finger is disposed substantially within a single one of the touch inputs in the first disposition, and the fingers are separated in the second disposition.

3. The electronic device of claim 1, wherein the combination is identified via a two-finger gesture wherein each finger is disposed substantially within two adjacent touch inputs in the first disposition, and the fingers are brought together in the second disposition.

4. The electronic device of claim 1, wherein the set of types of correction further comprises:

a symbol correction identified via a three-finger gesture in which each finger is substantially disposed within a single one of the touch inputs in the first disposition, and the three-finger gesture comprises a separation of each finger from each other and a merging of each finger to each other.

5. The electronic device of claim 4, wherein the separation of each finger from each other for the three-finger gesture is to change the single character from a lower case to an upper case and the merging of each finger to each other for the three-finger gesture is to change the single character from an upper case to a lower case.

6. The electronic device of claim 1, wherein the correction user interface is launched upon choosing the portion of the interpreted inputs and opening a menu including an option for the launching of the correction user interface.

7. The electronic device of claim 1, wherein the correction user interface includes at least the interpreted input data and the at least one touch input as entered by a user.

8. A method, comprising:

receiving at least one touch input via a touch sensitive display device;

generating interpreted input data as a function of the at least one touch input;

displaying the interpreted input data on the display device;

receiving a request to correct at least a portion of the interpreted input data;

switching to a correction mode; and

during the correction mode, performing the following sub-steps;

displaying a correction user interface on at least a portion of the display device;

receiving a gesture via the correction user interface, wherein the gesture is a multi-touch input comprising a multi-finger gesture;

determining a setting data as a function of a first disposition of the multi-finger gesture, the setting data indicating a portion of the interpreted inputs to which one of a set of types of correction is to be applied;

determining a correction data as a function of a second disposition of the multi-finger gesture; and

correcting the portion of the interpreted input data as a function of the at least one touch input, the setting data, and the correction data, wherein the set of types of correction comprises;

a separation to correct a split-over combination error; and

a combination to correct a combine-over segmentation error.

9. The method of claim 8, wherein the separation is identified via a two-finger gesture wherein each finger is disposed substantially within a single one of the touch inputs in the first disposition, and the fingers are separated in the second disposition.

10. The method of claim 8, wherein the combination is identified via a two-finger gesture wherein each finger is disposed substantially within two adjacent touch inputs in the first disposition, and the fingers are brought together in the second disposition.

11. The method of claim 8, wherein the set of types of correction further comprises:

a symbol correction identified via a three-finger gesture in which each finger is substantially disposed within a single one of the touch inputs in the first disposition, and the three-finger gesture comprises a separation of each finger from each other and a merging of each finger to each other.

12. The method of claim 11, wherein the separation of each finger from each other for the three-finger gesture is to change the single character from a lower case to an upper case and the merging of each finger to each other for the three-finger gesture is to change the single character from an upper case to a lower case.

13. The method of claim 8, wherein the correction user interface includes at least the interpreted input data and the at least one touch input as entered by a user.

14. A non-transitory computer readable storage medium including a set of instructions executable by a processor, the set of instructions operable to:

receive at least one touch input via a touch sensitive display device;

generate interpreted input data as a function of the at least one touch input;

display the interpreted input data on the display device;

receive a request to correct at least a portion of the interpreted input data;

switch to a correction mode; and

during the correction mode, the set of instructions operable to perform the following sub-steps;

display a correction user interface on at least a portion of the display device;

receive a gesture via the correction user interface, wherein the gesture is a multi-touch input comprising a multi-finger gesture;

determine a setting data as a function of a first disposition of the multi-finger gesture, the setting data indicating a portion of the interpreted inputs to which one of a set of types of correction is to be applied;

determine a correction data as a function of a second disposition of the multi-finger gesture; and

correct the portion of the interpreted input data as a function of the at least one touch input, the setting data, and the correction data, wherein the set of types of correction comprises;

a separation to correct a split-over combination error; and

a combination to correct a combine-over segmentation error.
