Video game device, video game method, video game program, and video game system

A video game device in which a real interface device that a player within a real space manipulates is represented by a virtual interface device within a virtual space, the video game device comprising:

• position detecting means that detects three dimensional coordinates of the real interface device within the real space;
• conversion means that converts the three dimensional coordinates of the real interface device within the real space into three dimensional coordinates within the virtual space, and displays the virtual interface device in the three dimensional coordinates within the virtual space on a display;
• and
• operating means that displays movements of the virtual interface device on the display, the operating means causing the position detecting means to detect the three dimensional coordinates of the real interface device within the real space and the conversion means to determine the three dimensional coordinates of the virtual interface device within the virtual space at predetermined time intervals;
• trajectory storing means that stores the three dimensional coordinates of the virtual interface device taken at predetermined time intervals;
• command storage means that stores a plurality of commands that are associated on a one-to-one basis with a plurality of predetermined trajectory patterns of the virtual interface device;
• and
• command execution means that calculates a trajectory of the virtual interface device based upon the three dimensional coordinates of the virtual interface device stored in the trajectory storing means, determines whether or not the trajectory matches any of the predetermined trajectory patterns, and executes the command associated with the predetermined trajectory pattern if a match exists.

• calculating a point in which an imaginary straight line that extends between the points on the real interface device intersects with the display and displaying a marker thereon;
• and
• determining whether or not the point lies on an object being displayed on the display, and allowing the player to select the object if the point lies thereon.
