    Publication number: 20160037153
    Abstract: An image rendering apparatus and method for rendering a stereoscopic image are provided. The image rendering apparatus may estimate a disparity of an image pixel included in an input image. Based on the disparity, a viewpoint direction of the image pixel may be determined by the image rendering apparatus. The image rendering apparatus may render a stereoscopic image by assigning a pixel value of the image pixel to a display pixel having a viewpoint direction corresponding to the viewpoint direction of the image pixel, instead of generating a multiview image.

  • APPARATUS AND METHOD FOR CONTROLLING INTERFACE
    Publication number: 20150370337
    Abstract: In an apparatus and method for controlling an interface, a user interface (UI) may be controlled using information on a hand motion and a gaze of a user without separate tools such as a mouse and a keyboard. That is, the UI control method provides more intuitive, immersive, and united control of the UI. Since a region of interest (ROI) sensing the hand motion of the user is calculated using a UI object that is controlled based on the hand motion within the ROI, the user may control the UI object in the same method and feel regardless of a distance from the user to a sensor. In addition, since positions and directions of view points are adjusted based on a position and direction of the gaze, a binocular 2D/3D image based on motion parallax may be provided.
