Title:
PERFORMANCE DEVICE AND PERFORMANCE DEVICE CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP3922273
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To carry out a enjoyable dynamic game by making the characteristics of music sounds variable corresponding to the moving mode of moving coordinates moving in a two dimensional area or the moving coordinates to match the shift in the inclination of a device itself or the way of moving it.
SOLUTION: In the performance device MC, matrix switches mtSW each of which has a matrix display segment mtLED arrayed correspondingly to each of them are arranged in a matrix. A G sensor 24 for detecting the accelerations in three-dimensional directions (X. Y and Z axes) is provided. In the G sensor mode, a slide movement of designated balls dp and moving balls mp is made or the speed of the moving balls mp is altered according to the changes in the accelerations in the directions of the X and Y axes. The cut-off frequency F of musical sound signals outptted from a sound source 12 is altered and set based on the changes (values of ZN-ZS) in the acceleration in the direction of the Z axis, thereby causing the variation in the characteristics of the musical sounds generated.
