  • Patent number: 10437360
    Abstract: Provided are a method and apparatus for moving contents on a screen in a terminal which allows a user to scroll in various directions within a contents page larger than a screen. An initial threshold region is established, which surrounds an initial touch point over displayed contents. A drag movement is detected from the initial touch point to a current touch point breaching the initial threshold region. The contents are moved in the direction of the drag movement if the current touch point is outside predetermined X and Y channels. The contents are moved in only the X or Y direction if the current touch point is within the X or Y channel, respectively. Thus, linear scroll of contents can be produced despite an unintentional nonlinear drag movement.
