Abstract: A method for spatial messaging includes the steps of setting, as a space for messaging, a location designated by a user as a virtual space assigned a unique coordinate value corresponding to a location in the real world; and collecting, as a message for the space, at least one content authored by another user who shares the corresponding space through a coordinate value of the space.

Abstract: A method of obtaining a route from a point of departure to a destination includes providing route guidance through an augmented reality (AR) view including an image captured by a camera. To provide route guidance, as a user terminal moves toward a destination on the basis of an obtained route, when an interaction occurs between the user terminal and a node or a link in which predetermined information included in the route is registered, content associated with the predetermined information is augmented and displayed as guidance information on an image of an AR view.

Abstract: A route guidance method includes acquiring a route from a source to a destination and providing route guidance through an augmented reality (AR) view that includes an image captured by a camera. When providing the route guidance, as a user terminal moves toward the destination based on the acquired route, a point indicator that guides to a turn point approached by the user terminal included in the route or an instruction indicator that instructs a movement to a corresponding turn point is displayed through augmentation on an image.

Abstract: Disclosed are an electronic device and an operating method of the electronic device, which relate to location-based augmented reality (AR) linkage of object-based augmentation content, and may recognize an object based on an image being captured, detect a preset location in association with at least one of the object and the image, determine augmentation content based on the object and the location, and output the augmentation content in correspondence to the object while displaying the image.

Abstract: Provided is a method and system for performing a map image search based on the context of an image. A map image search method may include receiving a query for a map image search; searching for a map image corresponding to the query using context that is acquired as an image analysis result of the map image; and providing a service or content using the map image corresponding to the query.

Abstract: An information sharing method includes the steps of creating a virtual space by assigning a unique coordinate value to a location specified by an electronic device; linking augmented reality (AR) content to the virtual space; and sharing the AR content linked to the virtual space via the coordinate value of the virtual space.

Abstract: Provided are methods, apparatuses, systems, and non-transitory computer readable media for image trend detection and curation. A method includes collecting image content created in association with each of events and performing image clustering with respect to each of the events; detecting information about a representative event that represents an image trend based on a cluster according to the image clustering; and providing information about the representative event to an electronic device, in response to a service request received from the electronic device over a network.

Abstract: Provided is a method and system for automatically updating a point of interest in a virtual exploration environment. The automatic update method may include marking a specific point in a virtual exploration environment using a panoramic image; updating information data associated with the specific point using location information corresponding to the specific point; and providing update information associated with the specific point to a user that marks the specific point.

Abstract: A method of sharing video through a chatting window of a messenger service includes generating a chatting window according to a request to create the chatting window. The request to create the chatting window is received from one of a plurality of chatting window participants. The chatting window includes a first portion where messages are to be displayed and a second portion where video is to be displayed. The first portion is allocated according to the request to generate the chatting window. A request to share video is received by at least one of the plurality of chatting window participants. The second portion is allocated according to the request to share video. The video is provided by displaying the video in the second portion, where at least one of the chatting window participants accessing the video via the second portion.

Abstract: An apparatus for analyzing a video capture screen includes: a video frame extracting unit extracting at least one frame from a video having a plurality of frames; an extracted frame digitizing unit digitizing features of each of the at least one frame extracted by the video frame extracting unit; an image digitizing unit digitizing features of at least one collected search target image; an image comparing and searching unit comparing the search target image with the at least one frame extracted from the plurality of frames by digitized values of the collected search target image and the at least one frame; and a search result processing unit mapping related information of the collected search target image to a frame coinciding with the search target image and storing the related information in a database, when the extracted at least one frame coinciding with the search target image is present in a comparison result.

Abstract: Disclosed herein is a group messaging system for providing file sharing through bidirectional interlock with a cloud server, including: a messenger server receiving information requesting creation of a group chatting room including group members and instructing user terminals of the respective group members to create the group chatting room; and a cloud server interlocking with the messenger server, receiving information about the creation of the group chatting room from the messenger server, and creating a sharing group mapped to the group chatting room in a one-to-one scheme.
