  • Patent number: 5512920
    Abstract: A three degree-of-freedom locator device for the control of graphical objects on a computer display mimics natural two-dimensional movement of the user's hand by providing for simultaneous translation and rotation of the graphical object. In one embodiment, a computer mouse-type locator with two trackball and position-encoder sensor systems detects movement of the locator over a stationary pad or like device. The graphical object is selected by a mouse button click. Subsequent two-dimensional translation and rotation of the locator are detected by the dual trackball system and used to control the position and orientation of the graphical object. The result is intuitive control of the placement of the selected object on the computer screen. The natural movement of the mouse in the user's hand is transformed into simultaneously translation and rotation of the object.

  • Patent number: 5512918
    Abstract: A method and apparatus for quickly copying a first frame region into a second frame region. A video memory array comprising a plurality of video random access memory devices is divided into at least two frame regions. A background image is rendered by a central processing unit into a background frame region within the video memory array. The central processing unit then requests the background image in the background frame region to be copied into a new frame region in the video memory array. A dedicated circuit copies the entire background image in the background frame region into the new frame region. The dedicated circuit operates by using a serial data register within each video random access memory device during the vertical retrace period of a video timing signal. The dedicated circuit performs the background frame copy without requiring any processing resources from the central processing unit.
