Abstract

There is provided an information processing apparatus including a position detection section which detects a position of an object, and a coordinate calculation section which calculates absolute coordinates based on the position of the object detected by the position detection section, and which calculates relative coordinates, which indicate a display position of the object on a screen, depending on the absolute coordinates and a motion of the object. The coordinate calculation section moves the relative coordinates in order for the relative coordinates to be asymptotic to or correspondent to the absolute coordinates based on a predetermined condition.
