Systems for a touchless musical instrument, where the touchless musical instrument includes: multiple sensors, where each sensor detects a presence of an object within a predetermined distance of the sensor; an audio speaker; a processor electrically connected to the sensors and the audio speaker; and executes instructions on the process to: receive, from the plurality of sensors, an object detection signal indicating a location of the object with respect to the plurality of sensors; generate an audio output signal based on the location of the object indicated by the object detection signal; and generate an audible output from the audio speaker by transmitting the audio output signal to the audio speaker.

To provide an electronic wind instrument capable of accurately detecting the amount of rotation of a transmission member. During an electronic wind instrument performance by a performer, external light (such as light from lighting) may easily shine on the upper surface side of an instrument main body. However, the light-receiving section of an optical sensor faces toward the bottom surface side of the instrument main body therefore external light from the upper surface side of the instrument main body can be prevented from reaching the light-receiving section of the optical sensor. As a result, erroneous detection of the external light by the optical sensor can be suppressed therefore the rotation amount of a transmission member can be accurately detected by the optical sensor.

A video game includes an audio-video stream combined with game graphics and game sounds. The game graphics are overlaid on the video stream and updated in synchronization with the stream. Update of the game graphics and sounds depends on inputs received from a game player. The game player may provide input using a game controller coupled to the video game by an adapter. The video game may play on a Blu-ray player.

A method and system for composing music, including: a plurality of game pieces, each representing a musical element and including a first communication module including an identifier that is associated with the musical element; at least one game track, comprising two or more positioning elements, each located at a predetermined position on the track and designed to accommodate placement of a game piece by a user, wherein each positioning element is associated with a respective second communication module configured to communicate with the first communication module of an accommodated game piece; and a computing device configured to: receive from at least one second communication module an identification of a game piece placed at a positioning element associated with the at least one second communication module; and play a tune based on the location of the positioning element and the identification of the game piece.

To provide an electronic wind instrument capable of accurately detecting the amount of rotation of a transmission member. An electronic wind instrument whereby contact with an optical sensor by a flat surface of a rear section can be suppressed even when at least a prescribed amount of a reed is bitten, as a result of the flat surface rotating in a direction away from the optical sensor when the rear section of the transmission member rotates in conjunction with displacement of the reed. As a result, the spacing between the facing flat surface and the optical sensor can be set comparatively narrowly in the initial state and the detection sensitivity at the optical sensor increased, thereby enabling accurate detection of the rotation amount of the transmission member (the amount of the reed that is bitten).

A device and method for an amplitude modulated optical pickup for a stringed instrument are disclosed. A first optical source comprising a first output signal comprising a first carrier frequency is provided and a first photodetector is in optical communication with the first optical source. A vibrating element such as a string on a musical instrument is disposed in an optical path between the first optical source and the first photodetector whereby a vibration of the element varies and modulates an amplitude of the first output signal received by the photodetector that is proportional to an element vibration amplitude and is at the same frequency as the element vibration frequency. An amplitude modulated (AM) photodetector signal output is generated from the first photodetector. The resultant signal is then demodulated with appropriate circuitry to produce a substantially noise free electronic signal representative of the element vibration frequency.
