Abstract: Embodiments of the inventive concept described herein relate to a method and a program for providing augmented reality image using depth data. According to an embodiment of the inventive concept, a method for providing an AR image using depth data includes a step S120 (a virtual image data receiving step) of receiving, by a client, virtual image data from a server, a step S140 (a display location determining step) of determining, by the client, a location, at which each pixel is to be displayed in a reality space, based on the depth data, and a step S160 (a virtual image data displaying step) of displaying the virtual image data in the reality space based on the determined location.

Abstract: Disclosed a precursor compound for producing a photoactive layer of a thin film solar cell that may be used as a precursor of a CIS, CGS or CIGS thin film that may be used as a photoactive layer of a solar cell, and a production method thereof. The precursor compound is represented by a following Chemical Formula 1: wherein, in the Chemical Formula 1, X represents indium (In) or gallium (Ga), Y represents chlorine (Cl) or iodine (I), each of R1, R2, R3 and R4 independently represents a methyl group, a propyl group or an alkyl group having 2 to 10 carbon atoms.

Abstract: Disclosed are a method for providing a virtual reality image, and a program using the same. The method includes receiving virtual reality image data from a server and allocating the virtual reality image data to a first layer, generating a second layer containing control information of at least one controller, receiving movement information of the at least one controller, and determining a collision point between a predetermined object in the virtual reality image data and the control information based on the movement information, modifying the control information based on a normal vector at the collision point, and allocating combination data including the modified control information to the second layer, and synthesizing the first layer and the second layer with each other to generate a last image frame.

Abstract: Disclosed are a method for transmitting a virtual reality image, a method for reproducing a virtual reality image, and a program using the same. A method for transmitting a virtual reality image includes an operation (S120) of creating an initial image frame by a server, an operation (S140) of determining image direction data corresponding to the initial image frame, an operation (S160) of creating a final image frame by coupling the image direction data to the initial image frame as meta information; and an operation (S180) of transmitting the final image frame to a client through wireless communication.
