First Claim
Patent Images
1. A touch-based input control method, comprising:
- a first step of implementing a virtual keyboard in a touch device;
a second step of identifying user touch input in a screen in which the virtual keyboard is displayed;
a third step of identifying moving of the user touch;
a fourth step of processing a keyboard stroke for a character in the virtual keyboard corresponding to the touch location if the touch becomes released without a predetermined threshold-over event for the user touch;
a fifth step of identifying input mode when the threshold-over event happens for the user touch; and
a sixth step of moving edit cursor corresponding to the moving direction of the user touch if the input mode is keyboard input mode.

Abstract
The present invention relates to touch-based input control technology in which cursor operation and pointer moving operation are properly identified by interpreting touch-based gesture in manipulating user terminals such as smart phones (e.g., i-phone) or smart pads (e.g., i-pad). According to the present invention, a user may easily, quickly and automatically control text input operation, cursor move operation and pointer move operation properly in context without cumbersome task of changing input modes.

8. The touch-based input control method, comprising:
-
a first step of implementing a virtual keyboard in a touch device; a second step of identifying multi-touch input on the virtual keyboard; a third step of identifying moving of the multi-touch; a fourth step of checking whether the multi-touch is released without identifying a predetermined threshold-over event for the multi-touch; a fifth step of, when a first location of the multi-touch is moving and a second location of the multi-touch is released, moving edit cursor corresponding to the touch-moving direction of the first location of the multi-touch with configuring the input mode into keyboard input mode; and a sixth step of, when the first location of the multi-touch is released and the a second location of the multi-touch is moving, moving control pointer corresponding to the direction and distance of the touch-moving of the second location with configuring the input mode into focus control mode. - View Dependent Claims (9, 10, 11, 12, 13)
