Abstract: A method for processing a virtual interview using division content, the method including generating a distribution inversely proportional to a usage amount of division content divided into a minimum unit to implement a virtual interview, extracting the division content in response to cache information of a user terminal, which includes content request information, transmitting combination content generated by combining the extracted division content to the user terminal, and controlling a selection probability in such a manner that the selection probability is inversely proportional to a usage amount of the extracted division content.

Abstract: A touch screen using infrared cameras hardly affected by external disturbance light includes an infrared radiation base having a plurality of infrared emitting elements and the infrared cameras, thereby preventing malfunction resulting from the external disturbance light. The touch screen includes a body having a screen part to which an image is output, an infrared radiation base having a plurality of infrared emitting elements and disposed around the screen part in transverse and longitudinal directions, and infrared cameras receiving the infrared light emitted from the infrared emitting elements of the infrared radiation base and detecting the position of an object touched on the screen part according to whether or not the infrared light emitted from each infrared emitting element is received.

Abstract: Disclosed are an apparatus and a method for adjusting a finger depth using a camera and a touch screen having the apparatus. The apparatus includes a light source installed at an edge of a panel to radiate light in parallel to a surface of the panel, a camera that photographs an object and light emitting points of the light source, and a control circuit that establishes a reference line having a predetermined finger depth by joining the light emitting points and limit lines having various finger depths which are remote from the reference line by several pixels corresponding to resolution of the camera. The control circuit determines whether the object approaches the reference line or the limit lines and determines a position of the object to output a display control signal. The apparatus allows a user to select a desired finger depth.
