Abstract: A method of displaying 3-dimensional (3D) augmented reality includes transmitting a first image generated by photographing a target object at a first time point, and storing first view data at the first time point; receiving first relative pose data of the target object; estimating pose data of the target object, based on the first view data and the first relative pose data of the target object; generating a second image by photographing the target object at a second time point, and generating second view data at the second time point; estimating second relative pose data of the target object, based on the pose data of the target object and the second view data; rendering a 3D image of a virtual object, based on the second relative pose data of the target object; and generating an augmented image by augmenting the 3D image of the virtual object on the second image.

Abstract: A detachable pad fastening structure of a helmet includes a first fastening unit, which includes a first fastening member having a fastening hole formed therein and is disposed at an inner surface of a helmet main body. A second fastening unit includes a through-hole in the form of a slot in a detachable pad and a second fastening member formed to be movable relative to the through-hole, having at least a part protruding toward the outside of the detachable pad so as to be inserted into the fastening hole when the second fastening member is located at one side of the through-hole, and configured to be inserted toward the inside of the detachable pad so as to be removed from the fastening hole when the second fastening member is moved relative to the through-hole toward the other side of the through-hole.

Abstract: A system for controlling brightness flicker of a parallax barrier LCD having a wide viewing angle capable of minimizing brightness flicker by adjusting a permittivity curve depending on different times into a predetermined waveform when split barriers are on/off by movement of a viewer's viewing angle, and a method thereof. A method of controlling brightness flicker of a parallax barrier LCD having a wide viewing angle for controlling brightness of a display providing a stereoscopic image by acquiring a real-time image of a viewer, recognizing an image of the viewer and extracting locations and coordinates of eyes of the viewer, and controlling turn-on/off of split barrier electrodes.

Abstract: A plasma display panel prevents mutual reaction between the cathode electrodes and resistance layers during the manufacturing process and reduces any decreasing of resistance values. Also, equal brightness on the entire surface of the screen and a high-resolution image is attained. And finally, the manufacturing process is made simple and there is optimization of the whole structure. Connect bars are inserted between the anodes and cathode electrodes in order to make equal, at every connecting discharge cell, the resistance values, and there is a reduction of contact resistance to such an extend that it can be discounted. Trigger electrodes and cathode bus lines, which emit auxiliary discharges, are formed parallel to each other on an identical plane. Branch electrodes that extend out from the trigger electrodes are arranged so as to extend out into the discharge cells.
