Abstract: A performance apparatus prevents a player's unintentional motion from being detected as a playing, thereby generating no sound, when the player plays a virtual musical instrument. The performance apparatus has a player operated stick, a ROM for storing layout information, which correlates plural areas set on a pickup-image plane to tone colors, respectively, an image sensor for continuously taking pickup images of a subject including the stick, and a CPU 21 for calculating a difference image between a first pickup image and a second pickup image taken prior to the first pickup image and for detecting an operating position of the stick based on the difference image. A CPU 31 refers to the ROM to specify a tone color correlated to the area corresponding to the operating position detected by CPU 21, and a sound source generates a tone of the tone color specified by CPU 31.

Abstract: A master terminal transmits sound waves that are a synchronization signal from a speaker to a slave terminal at random time intervals. Upon acquiring the sound waves that are the synchronization signal by microphone, the slave terminal promptly transmits a response signal through wireless communication to the master terminal. The master terminal receives the response signal and a terminal ID transmitted from the slave terminal. The master terminal receives the response signal multiple times and determines whether time intervals when synchronization signals were transmitted and time intervals when response signals were received match. When the synchronization signal time intervals and the response signal time intervals match, the master terminal recognizes the slave terminal that transmitted response signals at time intervals matching the synchronization signal time intervals as a wireless communication connection target. Slave terminals that transmitted response signals at time intervals not matching the synchronization signal time intervals are excluded from wireless communication connection targets.
