Disclosed is a device and method for representing HTML elements having three-dimensional (3D) information on web, the device including a virtual space providing unit configured to provide a 3D virtual space that is displayed on the web, and an HTML element placing unit configured to place an HTML element that is displayed in a 3D layout on the 3D virtual space, based on an HTML document.

Device and method for representing HTML elements having 3-dimensional information on web

A method for supporting 3D printing includes identifying a product, searching and providing a 3D model present on a web in relation to the identified product, calculating and simulating suitability between the identified product and the searched 3D model based on information of the identified product and the searched 3D model, and transmitting the 3D model information to a 3D printer to produce the 3D model. Accordingly, the 3D printing technique may be actively utilized for DIY in various fields, business models or the like.

Terminal and method for supporting 3D printing, and computer program for performing the method

There are provided an augmented reality contents providing apparatus based on a Web information structure including: an HTML document that includes a URI setting unit setting a uniform resource identifier (URI) corresponding to a point of interest (POI), a POI processing unit collecting attribute information from a target terminal and identifying the POI by using the collected attribute information, a virtual object processing unit that matches a virtual object associated with the URI to the identified POI; and a 3D browser engine used for setting coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through a Web browser of the target terminal, analyzing video information of the POI and the virtual object based on the set coordinates, and providing the target terminal the analyzed video information.

Apparatus and method providing augmented reality contents based on web information structure

Disclosed is a system for authoring and providing augmented reality contents, which includes a database storing a plurality of place models expressing an inherent physical place, a positioning unit for determining a current position of a user, a place model processing unit for searching and loading a place model corresponding to the current position of the user from the database, and a virtual object processing unit for disposing a virtual object expressed through a HTML document at a predetermined location in the loaded place model, wherein the plurality of place models is hierarchically stored so that at least one place model has at least one another place model of a subordinate concept.

System for authoring and providing augmented reality contents

Disclosed is a content management method, which includes obtaining data for a content including a plurality of point-of-interest (POI) and a plurality of POI documents associated with each of the plurality of POIs, obtaining at least one level-of-detail (LOD) information which allows the content to be displayed according to an interest of the user, and determining a display format for the content based on the LOD information. Here, the LOD information may include information for the interest level of the user with regard to the content, and the interest level may be independent from a scale level of a map at which the content is displayed.

Content management device and content management method

The motion tracking method disclosed herein suggests a method for precisely tracking the motion of a scanning device by correcting the surrounding information distortedly recognized due to the time differences between pieces of information regarding the surroundings of the device over one scanning cycle. The method, as a motion tracking method of a scanning device collecting the surrounding information corresponding to a plurality of the points of the surroundings, includes collecting the surrounding information, obtaining the displacement data of the scanning device using the surrounding information, updating the velocity of the scanning device using the displacement data of the scanning device, correcting the surrounding information using the updated velocity of the scanning device, and determining location and position information of the scanning device using the corrected surrounding information. According to the method herein, the motion of the scanning device may be more precisely tracked because the surrounding information is corrected based on the velocity of the scanning device.
