Abstract: Disclosed is an apparatus for obtaining 3D virtual object information which includes a 3D coordinates calculation portion for calculating 3D coordinates data for a body of a user to extract first space coordinates and second space coordinates from the calculated 3D coordinates data, a touch location calculation portion for calculating virtual object contact point coordinates for the surface of the virtual object building on the 3D map information that is met by a line connecting the first space coordinates and the second space coordinates extracted from the 3D coordinates calculation portion; and a space location matching portion for extracting virtual object (location) belonging to the virtual object contact point coordinates data calculated from the touch location calculation portion, and providing the extracted corresponding information of the virtual object to a display portion of a user's terminal or the apparatus for obtaining the 3D virtual object information.

Abstract: The present invention is to provide a transparent display virtual touch apparatus capable of exquisitely operating by a display portion worn on a user's face and located in front of an eye of a user and of identifying contents regardless of the direction and location of the user.

Abstract: Provided is a 3D game device using a virtual touch, the three-dimensional game device using a virtual touch includes a 3D game executing unit rendering a 3D stereoscopic game pre-stored in a game database and generating a 3D stereoscopic image regarding the rendered 3D game to provide the 3D stereoscopic image to a display unit, and a virtual touch unit generating spatial coordinate data of a specific point of a user and image coordinate data from a user's viewpoint using the 3D stereoscopic image provided from the display unit and comparing the generated spatial coordinate data and image coordinate data to verify whether or not a specific point of a user contacts or approaches the 3D stereoscopic image and thus recognize a touch of the 3D stereoscopic image.

Abstract: Disclosed is a remote control apparatus and method using a virtual touch of a three-dimensionally modeled electronic device. The remote control apparatus includes a 3D coordinate calculation unit, an electronic device detecting unit, a user detecting unit, an electronic device driving control unit, and an electronic device information database. The remote control apparatus enables the user to remotely control an operation of an electronic device using a virtual touch through a motion or gesture of the user's finger.

Abstract: Provided is a virtual touch device for remotely controlling electronic equipment having a display surface. The virtual touch apparatus include an image acquisition unit, a spatial coordinate calculation unit, a touch location calculation unit, and a virtual touch processing unit. The image acquisition unit includes two image sensors disposed at different locations and photographs a user's body at the front of the display surface. The spatial coordinate calculation unit calculates three-dimensional coordinate data of the user's body using an image from the image acquisition unit. The touch location calculation unit calculates a contact point coordinate where a straight line connecting between a first spatial coordinate and a second spatial coordinate meets the display surface using the first and second spatial coordinates received from the spatial coordinate calculation unit.

Abstract: Provided is a virtual touch apparatus and method for remotely controlling electronic equipment having a display surface. The virtual touch apparatus includes a three-dimensional coordinate calculator and a controller. The three-dimensional coordinate calculator extracts a three-dimensional coordinate of a user's body. The controller includes a touch location calculation unit and a virtual touch processing unit. The touch location calculation unit calculates a contact point coordinate where a straight line connecting between a first spatial coordinate and a second spatial coordinate meets the display surface using the first and second spatial coordinates received from the three-dimensional coordinate calculator. The virtual touch processing unit creates a command code for performing an operation corresponding to the contact coordinate received from the touch location calculation unit and inputs the command code into a main controller of the electronic equipment.

Abstract: A method of generating a frame sync signal of a mobile terminal is provided. The mobile terminal includes an input unit, which receives through an I-channel and a Q-channel frames into which a data frame transmitted from a base station is divided; a preamble detection unit, which detects timing information of the base station from a preamble pattern of the received frames; a frame sync pattern detection unit, which receives the frame through the I-channel and an output of the preamble detection unit and verifies the timing information; and a frame sync signal generation unit, which generates a frame sync signal according to an output of the frame sync pattern detection unit.
