Abstract: A method for processing of cursor in a touch screen is provided to process the input signal and to indicate a cursor in a screen in case a touch screen senses the contacts more than 2 points in the touch screen. A sensing point of the axis of x-direction of a screen is detected by an electrical signal. A sensing point of the axis of y-direction of a screen is detected by an electrical signal. The maximum coordinates and the minimum coordinates are set up from the coordinates of all spots of the detected x-axis. The maximum coordinates and the minimum coordinates are set up from the coordinates of all spots of the detected y-axis. It is determined that a size of a square consists of 4 points is within a predetermined threshold value. In case the size of square is within the predetermined threshold value, a circumscribed circle of the maximum size which includes 4 points of the square in a circumference or in a circle is set up as a cursor.

Abstract: PURPOSE: An apparatus and information controlling system on a network by hand action is provided to improve interaction between a user and various input devices/display devices under ubiquitous computing environment. CONSTITUTION: A controlling device(300) detects data input or file selection. A controlled device(400) interprets and displays data delivered from the controlling device. If the predetermined controlling device is selected and the predetermined controlled device is pointed by hand action, a management server(200) analyzes the hand action, and combines the selected controlling device with the pointed controlled device by a network. A combination management module controls network combination.

Abstract: A method for processing input of touch screen is provided to regularly maintain a reaction speed about an input signal and to solve an uncertain input signal process due to a malfunction of a sensor system and a scratch on a screen. A successive frame of a touch input domain on screen and a rear screen shot are photographed with a camera(S100). A color RGB(Red, Green, Blue) image photographed in the camera is transformed to a gray image(S110). A touch input domain is extracted about the gray image(S120). A center of the touch input domain is calculated to coordinate on frame(S130). A coordinates on a frame photographed by a camera in early stage is a reference point, and the coordinates on the next frames are stored as the vector data(S140). A displacement of stored vector data is calculated, and the displacement of vector data is acknowledged as the input signal on a screen(S150).
