Abstract
Provided are an apparatus and method for improving usability of a touch screen. The apparatus includes a touch sensing unit that senses a first touch and a second touch and detects the touched locations of the sensed touches, a pointer setting unit that sets a pointer to the detected location of the first touch, and a coordinate transforming unit that transforms movement of a touched location, which is caused by movement of the second touch, into movement of a location of the pointer.
