Abstract

When a cursor ( 105 : FIG. 12 ) is correctly manipulated in correspondence with guides (“G 1” to “G 4” and “g 1 ” to “g 5” : FIG. 12 ), the display of the dance object ( 106 : FIG. 12 ) and the background ( 110 : FIG. 12 ) is controlled in accordance with the manipulation direction of the cursor. The position of the operation article on a screen ( 91 : FIG. 1 ) is obtained as the coordinates of the cursor by intermittently irradiating an operation article ( 150 : FIG. 1 ) by a stroboscope and capturing the image thereof by an imaging unit ( 13 : FIG. 1 ).

       6 . The music game apparatus as claimed in  claim 1  wherein the guide is displayed in each of a plurality of positions which is determined in advance in a screen, and 
 wherein the guide control unit is operable to change the appearance of the guide in a timing on the basis of the music;    
   
   
       7 . The music game apparatus as claimed in  claim 1  wherein the guide is expressed in an image with which it is possible to visually recognize the motion from a first predetermined position to a second predetermined position on a screen, and 
 wherein the guide control unit is operable to control the display of the guide in a timing on the basis of the music.    
   
   
       8 . The music game apparatus as claimed in  claim 7  wherein the guide is expressed by the change in appearance of a plurality of objects which are arranged in a path having a start point at the first predetermined position and an end point at the second predetermined position on the screen.
