My motivation is audience usually shake their hands in a concert. It means people usually shake hands according to the beat or drum sound in the song. And smartphone becomes really popular in current days. So I propose a an application on smartphone, which lets user to change the speed of music and generate the drum sound by shaking their smartphone.
By using accelerometer and Geomegnetic rotation sensor built in smartphone, my system can detect user's tempo pattern in the interaction mode. First repeated pattern will trigger the music to play. and later repeated pattern will change the speed of the music. And in the drum mode, user can generate different drum sound by using different hand gesture.
