Abstract: The present invention relates to a technique for setting a text block based on a multi-touch manipulation performed by a user on a virtual keyboard of a touch device, such as a touch screen or a track pad, on a smart phone or a smart pad and performing various edit operations (copy, cut, paste, or block movement, etc.). According to the present invention, edit time is shortened and user convenience is provided when a user sets a text block and simplifies an edit process using multi-touches. In particular, when the present invention is applied to a virtual keyboard user environment, a text block can be set in a text sentence and various edit functions can be performed through a manipulation in the same style as a text input. Accordingly, document editing can be easily performed even in a smart phone having a small display.

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.
