The Miburi is a wearable musical instrument which was released commercially by the Yamaha Corporation’s Tokyo-based experimental division in 1994.〔Marrin, Teresa and Paradiso, Joseph “The Digital Baton: a Versatile Performance Instrument, International Computer Music Conference, Thessaloniki, Greece, pages 313-316, 1997”〕 == Categorisation and functions of the Miburi== The Miburi can be characterized as an “inside-in” system according to Axel Mulder’s three categories of motion sensing systems: * inside-in - sensor(s) and source(s) that are both on the body; * inside-out - on-body sensors that sense artificial external sources; * outside-in - external sensors that sense artificial sources on the body 〔Axel Mulder, Human movement tracking technology, Hand Centered Studies of Human Movement Project, Technical Report 94-1, 1994. “()”〕 It conforms to what Todd Winkler refers to as the ‘body sensor’ group of controllers (the other are spatial sensors, acoustic models and ‘new instruments’).〔Todd Winkler, “Composing Interactive Music: techniques and ideas using Max. Cambridge Massachusetts, MIT Press p. 315-8”, 1998〕 The Miburi system consists of a vest with embedded capacitive displacement sensors, two hand-grips, and shoe inserts with pressure sensors, and a belt-worn signal distribution unit joined by a cable to a small synthesizer/MIDI converter. A wireless version, conforming to Japanese wireless frequency regulations was available within Japan only. The Miburi's belt unit, “MBU-20”, processes data from the sensors into MIDI pitch and velocity information. The unit can be programmed to interpret the data using three ‘trigger’ modes: ‘Cross-point’ mode; ‘Stop’ mode and ‘All’ a combination of both modes. ‘Cross-point’ mode measures the speed of the transducer’s flexion asit traverses its zero point (when the flex sensor is straight). The six ‘flex’ sensors send 12 notes – this is because they measure inward and outward movement of each joint as separate notes. ‘Stop’ mode sends note and maximum velocity values at the conclusion of a gesture. ‘All’ interprets sensor data in both modes simultaneously.〔Yamaha Corporation, “Miburi R3 Manual. Tokyo, Japan: Yamaha Corporation”, 1996.〕 The mapping of each sensor is highly programmable. Each sensor can be mapped on the synthesizer unit, “MSU-20”, to any MIDI note, interpreted in any of the three modes outlined above according to 48 different response modes. The response modes (preset by Yamaha) define the manner in which the sensor’s output is graphed to velocity. All the above definitions are components of a single Map ‘Preset’, there are 32 programmable preset positions available. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Miburi」の詳細全文を読む スポンサード リンク
