Constructing Music Applications for Smartphones
Masathoshi Hamanaka, Mikito Yoshiya, Shyuhei Yoshida · 2011
This paper describes three applications for iPhone / iPod Touch: ShakeGuitar, BandNavi, and Twitraker. ShakeGuitar enables users to have a simulated experience of playing a guitar by simply shaking the iPhone / iTouch; shaking with varying degrees of strength influences the level of guitar-melody difficulty, which smoothly changes in real-time from soft backing to heavy soloing. BandNavi enables users to find new bands and music by examining the relations between musicians in bands, which are affected by member changes, collaborations, etc. Twitracker enables users to share music fragments by using twitter's time-line, and users can compose a piece of music using the fragments, even if they are musical novices. The main advantage of our applications is that they are based on our research on computer music. So far, our applications have been downloaded more than one hundred and fifty thousand times, and we have gotten a lot of positive comments from users. 1.
