Abstract: An electronic percussion instrument including: a detecting section which is provided in a stick and detects acceleration and angular speed based on movement of the stick; a first timing generating section which generates beat timing based on a predetermined tempo and beat width; a first pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section; and a sound production instructing section which instructs to produce a sound at the beat timing generated by the first timing generating section, when the first pre-sound-production movement detecting section detects the pre-sound-production movement.

Abstract: An input apparatus including: a first operation detecting section provided on a first operating section which detects acceleration and angular speed based on movement of the first operating section; a second operation detecting section provided on a second operating section which detects acceleration and angular speed based on movement of the second operating section; a judging section which judges whether or not the first and second operating sections have been held together, based on the accelerations and the angular speeds detected by the first and second operation detecting sections; a detecting section which detects a change operation based on the accelerations and the angular speeds detected by the first and second operation detecting sections, when the judging section judges that the first and second operating sections have been held together; and a changing section which changes a predetermined parameter in accordance with the change operation detected by the detecting section.

Abstract: A character recognition device which recognizes an operation for writing a character performed by a housing including an acceleration sensor 7 while being moved in a spatial plane based on a measurement result from the acceleration sensor, a control section 1 acquires acceleration data of each component acquired during the period from the start of writing to the end of the writing of one character determined based on acceleration data of a component associated with each axis of the acceleration sensor, as a series of acceleration data that are temporally continuous from the first stroke to the last stroke of the character including acceleration between strokes. The control section identifies feature points for each component that exist in a series of acceleration data, generates feature point data for each component which includes the plurality of feature points as inputted character data, and collates it with basic character data.
