Abstract

A system and method for document editing. A system includes an operator input device, a processor, gesture recognition program, and an edit mode program. The operator input device that senses gestures and multiple simultaneous touch points. The processor is coupled to the operator input device. The processor executes the gesture recognition program, which recognizes inputs from the input device. The gesture recognition program recognizes a predetermined edit mode gesture and, based only on the gesture, causes the processor to execute the edit mode program. The edit mode program provides a plurality of document editing functions for modifying a currently displayed document.

Claims

1. A system, comprising:

an operator input device that detects gestures and multiple simultaneous touch points;

a processor coupled to the operator input device, the processor executes a gesture recognition software program that processes inputs from the input device;

wherein the gesture recognition program recognizes a predetermined edit mode gesture and, based on the gesture, the processor executes an edit mode software program that provides a plurality of document editing functions for modifying a currently displayed document.

2. The system of claim 1, wherein the edit mode program when executed by the processor provides a cut function, a paste function, a copy function, and an undo function.

3. The system of claim 1, wherein the processor discontinues execution of the edit mode program when execution any one of the plurality of editing functions is complete.

4. The system of claim 1, wherein the gesture recognition program when executed by the processor causes the processor to execute the edit mode software program when the gesture recognition program causes the processor to detect two user contact points within a predetermined proximity to one another.

5. The system of claim 1, wherein the edit mode program causes the processor to execute a copy function when the gesture recognition program causes the processor to detect two user contact points on the input device within a predetermined proximity to one other and one of the user contact points subsequently moves in semi-circular arc to a lower position on the input device while the other user contact point is stationary.

6. The system of claim 1, wherein the edit mode program causes the processor to execute a paste function when the gesture recognition program causes the processor to detect two user contact points on the input device within a predetermined proximity to one other and one of the user contact points subsequently moves in semi-circular arc to higher position on the input device while the other user contact point is stationary.

7. The system of claim 1, wherein the edit mode program causes the processor to execute a cut function when the gesture recognition program causes the processor to detect a user contact point on the input device and the point subsequently moves in clockwise loop forming a teardrop bottomed letter ‘

X’

()

8. The system of claim 1, wherein the edit mode program causes the processor to execute an undo function when the gesture recognition program causes the processor to detect a user contact point on the input device and the point subsequently moves counterclockwise to form an uppercase letter ‘

U.’

9. A method, comprising:

receiving a first signal from a gesture input device indicating that a document editing mode program is to be executed;

executing the document editing mode program, the program allows a single selected editing operation of a plurality of available editing operations to be performed on a document;

receiving a second signal from the gesture input device selecting the single editing operation to be performed;

executing the single selected document editing operation;

exiting the document editing mode program on completion of the single selected document editing operation.

10. The, method of claim 9, further comprising selecting the single document editing operation from a group consisting of a cut operation, a paste operation, a copy operation, and an undo operation.

11. The method of claim 10, further comprising determining that the second signal indicates agesture selected from a group consisting of

a cut gesture formed by depressing a point on the gesture input device and subsequently moving the point in a clockwise loop forming a teardrop bottomed letter ‘

X’

();

a paste gesture formed by depressing two points on the gesture input device within a predetermined proximity to one other and subsequently moving one of the points in a clockwise semicircular arc to a higher position on the gesture input device while the other point remains stationary;

a copy gesture formed by depressing two points on the gesture input device within a predetermined proximity to one other and subsequently moving one of the points in a counterclockwise semicircular arc to a lower position on the gesture input device while the other point remains stationary; and

an undo gesture formed by depressing a point on the gesture input device and subsequently moving the point counterclockwise to form a uppercase letter ‘

U’

.

12. A computer readable medium encoded with a computer program comprising instructions that cause a processor to perform the operations of claim 10.

13. The computer readable medium of claim 12, further comprising instructions that cause a processor to perform the operations of claim 11.

14. A computer readable medium encoded with a computer program, comprising:

instructions that when executed cause a processor to perform an edit function selected from a group of edit functions comprising a copy function, a cut function, a paste function, and an undo function; and

instructions that when executed cause a processor to identify a gesture corresponding to a request to perform an editing function;

wherein the instructions that when executed cause the processor to identify an edit gesture cause the processor to identify a copy gesture formed by depressing two points on a gesture input device within a predetermined proximity to one other and subsequently moving one of the points in a counterclockwise semicircular arc to a lower position on the gesture input device while the other point remains stationary.

15. The computer readable medium of claim 14, wherein the instructions that when executed cause the processor to identify a gesture cause the processor to identify an edit function gesture selected from a group of edit function gestures consisting of:

a cut gesture formed by depressing a point on the gesture input device and subsequently moving the point in a clockwise loop forming a teardrop bottomed letter ‘

X’

();

a paste gesture formed by depressing two points on the gesture input device within a predetermined proximity to one other and subsequently moving one of the points in a clockwise semicircular arc to a higher position on the gesture input device while the other point remains stationary; and

an undo gesture formed by depressing a point on the gesture input device and subsequently moving the point counterclockwise to form a uppercase letter ‘

U.’
