Abstract: A handheld controller includes a three-axis, linear acceleration sensor that can detect linear acceleration in three directions, i.e., the up/down direction (Y-axis), the left/right direction (Z-axis), and the forward/backward direction (X-axis). A programmed object adjustment process adjusts a falling object to decrease the velocity v at which the object is moving in response to detected tilt changes in a first direction, and to increase the velocity v at which the object is moving in response to detected tilt changes in a second direction different from the first direction.

Abstract: First, at least a player object and a non-player object are placed in a virtual three-dimensional space. Next, the player object is moved based on an input from predetermined operation means. Subsequently, current position data is obtained which indicates the current position, in the virtual three-dimensional space, of the player object which has been moved. Based on the current position data, the orientation of the non-player object is controlled such that a predetermined plane of the non-player object faces the current position of the player object.

Abstract: An intentionally non-realistic video game simulation is provided in which Newtonian Physics may in part be optionally suspended. A truck or other vehicle flying through mid-air with no visible means of adjusting its own pitch and/or velocity may nevertheless adopt an attitude and/or velocity which corresponds to the attitude and/or velocity based on the tilt of a hand-held controller held by a human operator.
