Abstract: A position detection system includes: a scan beam illumination section which causes a first-direction line-shaped scan beam that is parallel to the X-axis to scan in the Y-axis direction at a predetermined scanning speed, then causes a second-direction line-shaped scan beam that is parallel to the Y-axis to scan in the X-axis direction at a predetermined scanning speed; a light-receiving section which detects the timings at which the first and second-direction line-shaped scan beams pass through a pointing position on a screen; and a position calculation section which calculates the pointing position by a pointing device on the screen, based on the time from the start of scanning of the first-direction line-shaped scan beam until the passage thereof through the pointing position is detected and the time from the start of scanning of the second-direction line-shaped scan beam until the passage thereof through the pointing position is detected.

Abstract: A game system for providing players with a higher sense of presence, a virtual reality environment and real-life simulations. A forward lean position of a player is detected by a forward lean position detector to carry out game computation to control a moving object on a screen according to operation information supplied by the player, including information indicative of the detected forward lean position. A force to rotate the moving object, a speed of the moving object and a motion of a cartoon character on the screen are controlled according to the forward lean position information. An information storage medium applicable to such a game system is also provided.

Abstract: To provide a game system which can lighten the burden imposed on a player and even the third person can enjoy, when a gun shooting game is played using a rifle equipped with a scope, a proximity sensor section (210) is provided on a gun device 200, for changing an image from a long-distance image to a short-distance image, using an image changing section (130) when it is judged that the player has come close to the proximity sensor section (210) and looks into the scope section (220), to thereby display the short-distance image on the display section (140).

Abstract: A simulator improved in operability and reality, in which a player can maintain a riding portion at a predetermined angle and return it to a neutral position, with the player's feet being apart from a base. The simulator has a base 112, a riding portion 114 located above the base 112, a rear end supporter 118 located on the base 112 to support the rear end of the riding portion 114 at a point, and a forward end supporter located on the base 112 to support the front end of the riding portion 114 so that the riding portion 114 can be rocked laterally from the neutral position about the rocking point in the rear end supporter 118.

Abstract: The present invention provides an action input device for a simulator that requires only a small installation space but can provide an extremely realistic experience.This travel simulator comprises a base portion 40, an input board 20 on which the player stands and rides, and an oscillatory mechanism that attaches the input board 20 in a freely oscillatory manner to the base portion 40, to form a travel simulator in which the input board 20 is made to oscillate in the leftward and rightward direction to control the direction of movement of a virtual player in the leftward and rightward direction.

Abstract: An operational input device is operated by an operator to control an image displayed on a projector screen. A grip bar is arranged such that it extends laterally of the operator sitting on a seat. The grip bar is rotatable around each of a vertical axis and a horizontal axis, so that it can freely move about the respective vertical and horizontal axes within a three dimensional space. Therefore, the operator can operate the grip bar as if it is a paddle of a canoe. Since the grip bar extends laterally of the operator, a plurality of operators can grasp the grip bar simultaneously.
