Zooming Method
First Claim
1. A method of zooming in a graphical user interface of an electronic device having a touch screen for receiving input from a user via touch interactions, wherein the method comprises:
- detecting a first touch event, which is the result of a first touch interaction at a first coordinate of said touch screen;
detecting a second touch event, which is the result of a second touch interaction, subsequent to the first touch interaction, at a second coordinate of said touch screen;
detecting a third touch event, which is the result of a third touch interaction, subsequent to the second touch interaction, at a third coordinate of said touch screen; and
controlling the touch screen to perform a zoom operation on an image displayed on the graphical user interface, wherein the zoom operation is representative of a first distance L1 between the first coordinate and the second coordinate and a second distance L2 between the first coordinate and the third coordinate.

Abstract
A method of zooming in a graphical user interface of an electronic device (1) having a touch screen (2) for receiving input from a user via touch interactions is disclosed. The method comprises detecting a first touch event, which is the result of a first touch interaction at a first coordinate (c1) of said touch screen (2). The method further comprises detecting a second touch event, which is the result of a second touch interaction, subsequent to the first touch interaction, at a second coordinate (c2) of said touch screen (2). Furthermore, the method comprises detecting a third touch event, which is the result of a third touch interaction, subsequent to the second touch interaction, at a third coordinate (c3a, c3b) of said touch screen (2). Moreover, the method comprises controlling the touch screen to perform a zoom operation on an image displayed on the graphical user interface. The zoom operation is representative of a first distance L1 between the first coordinate (c1) and the second coordinate (c2) and a second distance L2 between the first coordinate (c1) and the third coordinate (c3a, c3b). A corresponding electronic device, a corresponding computer program product, and a corresponding computer readable medium are also disclosed.

15. An electronic device comprising:
-
a touch screen having a graphical user interface and configured to receive input from a user via touch interactions; and a control unit operatively connected to the touch screen and configured to; detect a first touch event, which is the result of a first touch interaction at a first coordinate of said touch screen; detect a second touch event, which is the result of a second touch interaction, subsequent to the first touch interaction, at a second coordinate of said touch screen; detect a third touch event, which is the result of a third touch interaction, subsequent to the second touch interaction, at a third coordinate of said touch screen; and control the touch screen to perform a zoom operation on an image displayed on the graphical user interface, wherein the zoom operation is representative of a first distance L1 between the first coordinate and the second coordinate and a second distance L2 between the first coordinate and the third coordinate. - View Dependent Claims (16, 17, 18)
