Abstract

One embodiment provides a system for processing gesture inputs on a touch screen display. The system receives a gesture input on the touch screen display. When the gesture is recognized as invoking an annotation canvas, the system determines the height, width and location of an annotation canvas, and displays the annotation canvas on the touch screen display. Then, in response to an input gesture within the annotation canvas, the system recognizes the gesture as an annotation gesture, and executes the annotation gesture. In response to receiving an input gesture outside of the annotation canvas, the gesture is interpreted by the system as a navigation input.

Claims

1. A computer implemented method of processing a gesture input on a touch screen display device, the method comprising:

receiving a gesture input on the touch screen display;

recognizing the gesture as invoking an annotation canvas;

determining a height and a width of the annotation canvas;

displaying the annotation canvas on the touch screen display;

responsive to receiving an input gesture within the annotation canvas, interpreting the gesture as an annotation gesture for input an annotation, and executing the annotation gesture; and

responsive to receiving the input gesture outside of the annotation canvas, interpreting the gesture as a navigation input.

2. A computer implemented method of claim 1, wherein:

receiving a gesture input on the touch screen display further comprises receiving a user'"'"'s touch on the touch screen display.

3. A computer implemented method of claim 2, further comprising:

displaying the annotation canvas on the touch screen display so long as the user'"'"'s touch is maintained on the touch screen display; and

responsive to the user'"'"'s touch being removed from the touch screen display, removing the annotation canvas.

4. A computer implemented method of claim 1, wherein determining a height and a width of the annotation canvas comprises:

determining a first location on the touch screen display at which the gesture invoking the annotation canvas is received by one hand of the user;

determining a second location corresponding to the location of the other hand of the user on the touch screen display; and

determining the width of the annotation canvas based on distance between the first location and the second location.

5. A computer implemented method of claim 1, wherein responsive to receiving the input gesture outside of the annotation canvas, interpreting the gesture as a navigation input further comprises:

blocking execution of the navigation input while an annotation gesture is being received and executed within the annotation canvas.

6. A computer implemented method of claim 1, wherein responsive to receiving the input gesture within the annotation canvas, the method further comprising:

expanding the area of the annotation canvas towards the input gesture in response to the gesture being near a border of the canvas.

7. A computer implemented method of claim 1, further comprising:

displaying an annotation control panel comprising a plurality of annotation controls, each annotation control for configuring a parameter of an annotation to be input into the annotation canvas.

8. A touch screen display apparatus, comprising:

a touch screen display configured to receive multiple concurrent touch inputs;

a memory configured to store an application data and gesture data;

a processor configured to perform a method comprising;

receiving a gesture input on the touch screen display;

recognizing the gesture as invoking an annotation canvas;

determining a height and a width of the annotation canvas;

displaying the annotation canvas on the touch screen display;

responsive to receiving an input gesture within the annotation canvas, interpreting the gesture as an annotation gesture for input an annotation, and executing the annotation gesture; and

responsive to receiving the input gesture outside of the annotation canvas, interpreting the gesture as either a navigation input.

9. A touch screen display apparatus of claim 8, wherein while receiving a gesture input on the touch screen display, the method further comprises:

receiving a user'"'"'s touch on the touch screen display

10. A touch screen display apparatus of claim 9, wherein the method further comprises:

displaying the annotation canvas on the touch screen display so long as the user'"'"'s touch is maintained on the touch screen display; and

responsive to the user'"'"'s touch being removed from the touch screen display, removing the annotation canvas.

11. A touch screen display apparatus of claim 8, wherein determining a height and a width of the annotation canvas comprises:

determining a first location on the touch screen display at which the gesture invoking the annotation canvas is received by one hand of the user;

determining a second location corresponding to the location of the other hand of the user on the touch screen display; and

determining the width of the annotation canvas based on distance between the first location and the second location.

12. A touch screen display apparatus of claim 8, wherein responsive to receiving the input gesture outside of the annotation canvas, interpreting the gesture as a navigation input further comprises:

blocking execution of the navigation input while an annotation gesture is being received and executed within the annotation canvas.

13. A touch screen display apparatus of claim 8, wherein responsive to receiving the input gesture within the annotation canvas, the method further comprises:

expanding the area of the annotation canvas towards the input gesture in response to the gesture being near a border of the canvas.

14. A touch screen display apparatus of claim 8, wherein the method further comprises:

displaying an annotation control panel comprising a plurality of annotation controls, each annotation control for configuring a parameter of an annotation to be input into the annotation canvas.

15. A computer implemented method of processing a gesture input on a touch screen display device, the method comprising:

receiving a gesture input on the touch screen display;

recognizing the gesture as invoking a local region associated with an input mode;

determining a location and a size of the local region;

displaying the local region on the touch screen display; and

responsive to receiving an input gesture within the local region, interpreting the gesture as an input for the input mode and executing a function associated with the gesture.

16. A touch screen display apparatus, comprising:

a touch screen display configured to receive multiple concurrent touch inputs;

a memory configured to store an application data and gesture data;

a processor configured to perform a method comprising;

receiving a gesture input on the touch screen display;

recognizing the gesture as invoking a local region associated with an input mode;

determining a location and a size of the local region;

displaying the local region on the touch screen display; and

responsive to receiving an input gesture within the local region, interpreting the gesture as an input for the input mode and executing the gesture.
