Abstract: A smart watch and a control method thereof are provided. A smart watch includes a display having a position that is changeable; an estimation-based position controller configured to determine an initial target position based on a face position and control the display to be moved to the determined initial target position; a face position determiner configured to, based on a face recognition result, determine whether a face exists in front of the display positioned at the initial target position; and a face recognition-based position controller configured to, in response to determining a face does not exist in front of the display, determine a modified target position to enable the display to be positioned toward a face and control the display to be moved to the modified target position.

Abstract: An apparatus is configured to structure contents of a meeting. The apparatus includes a voice recognizer configured to recognize a voice to generate text corresponding to the recognized voice, and a clustering element configured to cluster the generated text into subjects to generate one or more clusters. The apparatus further includes a concept extractor configured to extract concepts of each of the generated clusters, and a level analyzer configured to analyze a level of each of the extracted concepts. The apparatus further includes a structuring element configured to structure each of the extracted concepts based on the analysis.

Abstract: A terminal and a method for sharing content are provided. A terminal includes an image acquirer configured to acquire face image data from a camera while content is being displayed, a face recognizer configured to recognize a face included in the face image data, a face change detector configured to detect whether the recognized face is different from a face recognized in a previous image data, a contact searcher configured to, in response to the detection that the recognized face is different from the face recognized in the previous image data, search a contact corresponding to the recognized face, and an information transmitter configured to transmit content usage information to the searched contact.

Abstract: A method of generating a user lifelog includes dividing detection data into data units; recognizing a plurality of user activities from arrangements of the data units; generating a plurality of user activity logs by time-sequentially linking the plurality of the recognized user activities; and generating a user lifelog by hierarchically structuring the plurality of user activity logs based on a correlation between the user activity logs.

Abstract: Provided is a three-dimensional (3D) display system. The 3D display system synthesizes a 3D image and position information data of an observer obtained through a camera with an optimal viewing area image with respect to horizontal and vertical directions of a display panel in a 3D space, and displays the synthesized image on the display panel such that the observer can visually know an optimal viewing area. Accordingly, the 3D display system enables the observer to visually check the optimal viewing area with ease and induces the observer to move to a position in the optimal viewing area.
