Abstract:
A display apparatus including a communicator configured to perform data communication with a content server and to receive at least one of a main document and a sub document related to the main document; a document analyzer configured to extract a keyword having a high frequency of occurrence from the main document and to determine a head keyword for generating a summarized document from the extracted keyword with reference to the received sub document; and a processor configured to determine a reliability of each sentence of the main document based on the head keyword, extract a sentence that matches a predetermined condition with reference to the determined reliability, and analyze a structural format of the extracted sentence so as to re-configure a word that forms the sentence and generate a summarized sentence, thereby generating a summarized document where information and logical cohesion have been obtained.
Abstract:
A view sensor, a home control system including the view sensor, and a method of controlling the home control system are provided. The view sensor includes: a lens unit configured to receive light in order to capture an image or project light in order to display the image; an image acquirer configured to acquire the image by using the light received from the lens unit; a projector configured to provide light to the lens unit in order to display the image; a beam splitter configured to provide the image acquirer with the light received from the lens unit or transmit the light generated by the projector to the lens unit; and a controller configured to, in response to the image being captured, control the beam splitter to provide the image acquirer with the light received from the lens and, in response to the image being displayed, control the beam splitter to provide the lens unit with the light generated by the projector.
Abstract:
An apparatus and method for sensing body information is provided. The apparatus includes: a light-emitting device configured to emit a light signal toward an object that is to be sensed; a light-receiving device configured to detect a reflected light signal reflected from the object; an image sensor configured to detect the reflected light signal reflected from the object; and a controller configured to selectively drive at least one of the light-receiving device and the image sensor according to a distance between the object and the light-emitting device and to sense volume information or blood flow information of the object by using the reflected light signal.
