Abstract

The invention is directed to a computer-implemented method for duplicating an object using a touch-sensitive display. The method comprises: (i) displaying a selected first object on the touch-sensitive display; (ii) detecting a first user interaction and a second user interaction on the selected first object; (iii) detecting a movement of the first user interaction outside the selected first object; (iv) displaying a second object which tracks the movement of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and (v) positioning the second object according to a last detected location of the first user interaction on the touch-sensitive display.

Claims

1. A computer-implemented method for duplicating an object using a touch-sensitive display, the method comprising:

displaying a selected first object on the touch-sensitive display;

detecting a first user interaction and a second user interaction on the selected first object;

detecting a movement of the first user interaction outside the selected first object;

displaying a second object which tracks the movement of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and

positioning the second object according to a last detected location of the first user interaction on the touch-sensitive display.

2. The method of claim 1, further comprising, after the step of detecting a movement of a first user interaction, the step of:

detecting the end of the second user interaction on the selected object.

3. The method of claim 1, wherein the first user interaction and the second user interaction are performed concomitantly or successively, independently of the order of their detection on the selected first object.

4. The method of claim 1, wherein the last detected location of the first user interaction is the location on which the end of the first user interaction on the touch-sensitive display is detected.

5. The method of claim 1, wherein the step of displaying a selected first object and the step of positioning the second object are performed within a same window of a graphical user interface.

6. The method of claim 1, wherein, at the step of displaying a second object, the rendering of the second object is modified in comparison with the rendering of the first object.

7. The method of claim 1, wherein the first user interaction and the second user interaction are performed by the contact on the touch-sensitive display by at least one of the following or the combination of:

a stylus;

a finger.

8. The method of claim 1, wherein the first user interaction and the second user interaction are performed by the contact on the touch-sensitive display of a respective finger of two hands of the user.

9. A computer program, stored on a computer readable medium, for duplicating an object using a touch-sensitive display, comprising code means for causing a computer to take the steps of:

displaying a selected first object on the touch-sensitive display;

detecting a first user interaction and a second user interaction on the selected first object;

detecting a movement of the first user interaction outside the selected first object;

displaying a second object which tracks the movement of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and

positioning the second object according to a last detected location of the first user interaction on the touch-sensitive display.

10. An apparatus for duplicating an object using a touch-sensitive display, the apparatus comprising means for:

displaying a selected first object on the touch-sensitive display;

detecting a first user interaction and a second user interaction on the selected first object;

detecting a movement of the first user interaction outside the selected first object;

displaying a second object which tracks the movement of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and

positioning the second object according to a last detected location of the first user interaction on the touch-sensitive display.
