  • Patent number: 9715326
    Abstract: Technologies are generally described for systems and methods effective to display a first output and simultaneously display a second output corresponding to user input superimposed on the first output. In some examples, a second output is displayed on a display simultaneously with and superimposed on a first output. The second output corresponds to user input. In an area of the display that the first output and the second output overlap, the second output is opaque and the first output is visible through the opaque second output. In an area of the display that the first output and the second output do not overlap, the first output is visible. The first output may be a video portion of a video telephone conference, and the second output may correspond to annotations or notes that are received from a user during the telephone conference.

  • Patent number: 9081414
    Abstract: The disclosure relates to controlling and manipulating an image of an object on a display device based on tracked eye movements of an observer. When the object is displayed according to an initial view, the observer's eye movement is tracked and processed in order to determine the focus of the observer's attention or gaze on the image. Thereafter, the displayed image is modified to provide a better view of the part of the object in which the observer is most interested. This is accomplished by modifying at least one of the spatial positioning of the object within the viewing area, the angle of view of the object, and the viewing direction of the object.

  • Patent number: 8934708
    Abstract: A method, apparatus, computer readable medium storing computer readable instructions are disclosed for processing volumetric image data. According to the method, 3-dimensional data points are collected. A plurality of 2-dimensional image maps is obtained from the 3-dimensional data points. At least one of the plurality of 2D image maps is extracted to form at least one image frame. A frame gallery is created from the at least one image frame.
