Abstract

A method and apparatus are provided for recognizing multi-touch gestures on a touch sensitive display. A plurality of graphical objects is displayed within a user interface (UI) of a display screen operable to receive touch input. A first touch input exceeding a first time duration is detected over a first graphical object. A touch-and-hold gesture action is generated, which is then applied to the first graphical object. A second touch input is then detected over a second graphical object and a touch-select gesture action is generated, which is then applied to the second graphical object. The first and second gestures are processed to determine an associated operation, which is then performed on the second graphical object.

Claims

1. A method for recognizing multi-touch input on a display screen, the method comprising:

displaying a plurality of graphical objects in a user interface of a display screen operable to receive touch input from a user;

detecting a first touch input associated with a first graphical object, the first touch input lasting a first duration of time;

generating a gesture action if the first duration of time is longer than a first reference amount of time; and

detecting a second touch input associated with a second graphical object.

2. The method of claim 1, wherein:

the first touch input is detected as a result of a first finger on a hand of a user being in proximate contact with the first graphical object; and

the second touch input is detected as a result of a second finger on a hand of a user being in proximate contact with the second graphical object.

3. The method of claim 1, wherein:

the generated gesture action simulates a touch-and-hold user gesture, the touch-and-hold gesture applied to the first graphical object; and

the second touch input is a touch-select user gesture, the touch-select gesture applied to the second graphical object.

4. The method of claim 1, wherein the second touch input is performed within a second reference amount of time subsequent to the generation of the gesture action.

5. The method of claim 1, further comprising:

processing the first and second touch inputs to determine an operation to be performed on the second graphical object

performing the operation on the second graphical object.

6. The method of claim 5, wherein the operation performed on the second graphical object results in the second graphical object being moved to the first graphical object.

7. The method of claim 5, wherein the operation performed on the second graphical object results in the second graphical object being executed by the first graphical object.

8. The method of claim 1, further comprising:

terminating the generated gesture action, responsive to an occurrence of a terminating event.

9. The method of claim 8, wherein the terminating event includes one of a:

detection of an end of the first touch input prior to the detecting of a second touch input; and

expiration of the second reference amount of time before the detecting of a second touch input.

10. The method of claim 1, wherein the display screen is operable to perform palm-rejection on a touch input.

11. An apparatus for recognizing multi-touch input on a display screen, the apparatus comprising:

means to display a plurality of graphical objects in a user interface of a display screen operable to receive touch input from a user;

means to detect a first touch input associated with a first graphical object, the first touch input lasting a first duration of time;

means to generate a gesture action if the first duration of time is longer than a first reference amount of time; and

means to detect a second touch input associated with a second graphical object.

12. The apparatus of claim 11, wherein:

the first touch input is detected as a result of a first finger on a hand of a user being in proximate contact with the first graphical object; and

the second touch input is detected as a result of a second finger on a hand of a user being in proximate contact with the second graphical object.

13. The apparatus of claim 11, wherein:

the generated gesture action simulates a touch-and-hold user gesture, the touch-and-hold gesture applied to the first graphical object; and

the second touch input is a touch-select user gesture, the touch-select gesture applied to the second graphical object.

14. The apparatus of claim 11, wherein the second touch input is performed within a second reference amount of time subsequent to the detection of the first touch input.

15. The apparatus of claim 11, further comprising:

means to process the first and second touch inputs to determine an operation to be performed on the second graphical object

means to perform the operation on the second graphical object.

16. The apparatus of claim 15, wherein the operation performed on the second graphical object results in the second graphical object being moved to the first graphical object.

17. The apparatus of claim 15, wherein the operation performed on the second graphical object results in the second graphical object being executed by the first graphical object.

18. The apparatus of claim 11, further comprising:

means to terminate the generated gesture action, responsive to an occurrence of a terminating event.

19. The apparatus of claim 18, wherein the terminating event includes one of a:

detection of an end of the first touch input prior to the detecting of a second touch input; and

expiration of the second reference amount of time before the detecting of a second touch input.

20. The apparatus of claim 11, wherein the display screen is operable to perform palm-rejection on a touch input.
