ABSTRACT:
An apparatus and method for providing a virtual graffiti function and a recording medium for the same. The apparatus for providing a virtual graffiti function includes: a touch-screen display for displaying information on its screen, and at the same time receiving user-entry data created by a user touching the screen; and a controller connected to the touch-screen display, which overlaps a graffiti screen image with a main screen image in a virtual graffiti area for providing a portion of the screen with virtual graffiti, classifies the user-entry data created by the user touching the screen into application execution entry data and graffiti entry data according to the touched position and/or method, and processes the classified user-entry data differently from each other. Therefore, the apparatus can effectively implement a graffiti function in a hand-held device limited in size, and can also provide an effective recording medium.
