Abstract: The present invention discloses a method and apparatus for controlling an object movement on a screen. The method senses a first change in a position of a pointing device in a coordinate system to obtain a first displacement, and controls the object movement by a first displacement output ratio according to the first displacement. The method senses a second change in a position of the pointing device in a coordinate system to obtain a second displacement, and controls the object movement by a second displacement output ratio when a difference between a direction of the first displacement and a direction of the second displacement exceeds a first angle threshold, wherein the second displacement output ratio is lower than the first displacement output ratio.
