GRAPHICAL OBJECT MANIPULATION WITH A TOUCH SENSITIVE SCREEN
First Claim
Patent Images
1. A method for graphical object manipulation using a touch sensitive screen, the method comprising:
- detecting a presence of two user interactions within a defined boundary of a graphical object displayed on the touch sensitive screen;
determining position of each of the two user interactions with respect to the graphical object;
detecting displacement of at least one of the two user interactions; and
manipulating the graphical object based on the displacement to maintain the same position of each of the two user interactions with respect to the graphical object.

Abstract
A method for graphical object manipulation using a touch sensitive screen, the method comprises detecting a presence of two user interactions within a defined boundary of a graphical object displayed on the touch sensitive screen, determining position of each of the two user interactions with respect to the graphical object, detecting displacement of at least one of the two user interactions, and manipulating the graphical object based on the displacement to maintain the same position of each of the two user interactions with respect to the graphical object.

20. A method for graphical object manipulation using a touch sensitive screen, the method comprising:
-
determining global coordinates of a plurality of user interactions on a touch sensitive screen, wherein the global coordinates are coordinates with respect to a global coordinate system locked on the touch sensitive screen; detecting a presence of two user interactions within a defined boundary of a graphical object displayed on the touch sensitive screen, wherein the presence is determined from the global coordinates of the two user interactions and the global coordinates of the defined boundary of the graphical object; defining a local coordinate system for the at least one graphical object, wherein the local coordinate system is locked on the at least one graphical object; determining coordinates of each of the two user interactions in the local coordinate system; detecting displacement of a position of at least one of the two user interactions; and manipulating the at least one graphical object in response to the displacement to maintain the same coordinates of the two user interactions determined in the local coordinate system. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
