  • Auto-scrolling with mouse speed computation during dragging
    Patent number: 5726687
    Abstract: A system for scrolling during a drag and drop operation is provided wherein the determination of whether to scroll is based on the location of a mouse indicator as well as the speed of the mouse indicator. The system maintains a predetermined threshold that is empirically proven to reliably distinguish as to whether a user wishes to perform a drag and drop operation or whether the user wishes to invoke the automatic scrolling of the present invention. The system determines when the mouse indicator is over a predefined area of a window, compares the speed of the mouse indicator to the predetermined threshold and scrolls the window if the mouse indicator is over the predefined area and the speed is less than the predetermined threshold.
    Type: Grant
