A display system and method for use in controlling movement of a virtual image version of a physical object is described. A physical object may be placed on or near a display surface, which may sense the presence of the object and display a virtual image version of the object. In response to movement of the physical object, the virtual image may move as well. Movement speed of the virtual image may be capped at a maximum speed, so that if the physical object is moved too quickly, the image will remain moving at a constant maximum speed. Movement effects, such as blurring, fading, animation, etc. may be applied to the image during the movement. The movement may change direction as the physical object is detected in different positions, and the movement effects may be applied to smooth the change in direction (e.g., curving trajectory).
