It seems that we have seen already all ways of controlling our application. But sometimes you can find new approach for already known issues. As an example we should look at innovative way of controlling application used in Sax app. This is next application that is simulating some musical instrument. It this case it is a saxophone.
But in this case you use the whole phone to control the application. As it is in other apps you need to tap the screen to get some sounds. The new thing is adding gyroscope to this process. Each change of the position of your phone will modify output sound.
