Abstract:
1. An input device comprising: a first operation detecting section which is provided on one stick and detects acceleration based on movement of the one stick; a second operation detecting section which is provided on an other stick and detects acceleration based on movement of the other stick; a note-ON operation judging section which judges a note-ON operation in which each of the one stick and the other stick a swung upwards after being swung downwards when detected that a polarity change from positive to negative has occurred between polarity of acceleration data acquired last time and polarity of the acceleration data acquired this time from the each of the first operation detecting section and the second operation detecting section; a first instructing section which instructs to produce a sound associated with the each of the one stick and the other stick, when the note-ON operation judging section judges the note-ON operation; a first strike judging section which judges that the one stick and the other stick have struck against one another, when detected that sudden acceleration changes in mutually different directions occur in the first operation detecting section and the second operation detecting section simultaneously; and a second instructing section which instructs to produce a sound corresponding to striking of the one stick and the other stick against one another and differing from the sound that the first instructing section instructs to produce, when the first strike judging section judges that the one stick and the other stick have struck against one another.
