Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a method for mashing up heterogeneous sensors, which includes collecting an activity log from at least one sensor, converting the collected activity log into a common markup format, extracting an activity of a user from the activity log, based on an activity model which defines relations among activities, and outputting the extracted activity of the user in a semantic unit. Thus, it is possible to integrally utilize information of heterogeneous sensors, provide meaningful and intuitive information to a user, and share information of various applications and devices.

Abstract: Disclosed is a method and apparatus for managing content media. The method for managing content media includes creating or receiving content media, receiving level of detail (LOD) setting information at which the content media is displayed, and determining a display format of a point of interest (POI) on the content media based on the LOD setting information.
