Method and system for duplicating an object using a touch-sensitive display

摘要

The invention is directed to a computer-implemented method and system 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.

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, wherein the first object corresponds to an assembly of three dimensional (3D) modeled objects or a part of a 3D modeled object; detecting a first user interaction and a second user interaction on the selected first object, wherein the first user interaction and the second user interaction each have a respective beginning and end and each are performed by as few as one contact on the touch-sensitive display; detecting a movement of sliding of the first user interaction outside an outline of the selected first object, such that said detecting begins when the first user interaction is outside the outline; after detecting the movement of sliding of the first user interaction outside the outline of the selected first object, detecting a release of the second user interaction on the selected first object; displaying a second object, after the first user interaction is outside the outline, which tracks the movement of sliding of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and after detecting the release of the second user interaction, positioning the second object according to a last detected location of the first user interaction on the touch-sensitive display.
