Implementation of non-stringed guitar using ATMega128

When guitarists play the guitar for music concert, they need to change guitar strings and tune guitar prior to the concert. In this paper, we propose non-stringed guitar to improve these troublesome things. Non-stringed guitar consists of three parts: chord glove, processor and sound processing software. First, the chord glove composed of FSR and FLEX sensors representing guitar chords. Second, the processor, ATMega128 recognizes guitar chords. Finally, each of sound pitches is transmitted to the sound processing software called Max/MSP. Therefore, Max/MSP can play guitar chords at certain pitch by using graphical object, such as dasiaserialpsila object, dasiaopenpsila object and so on. Also, up and down stroke can be expressed by using different delay.
