Ocarina 2.0 is an attempt at exploratory development in using breath as a control via game demos. The use of breath can be very useful in enhancing one's ability to interact with technology. Development in using breath can lead to easier interaction with technology for the disabled, or can be used to enhance one's experience in a game. Take for example, the popular Zelda games, where one aspect of the game is playing an Ocarina. We could enhance the game by allowing one to breath into the controller to play the notes. Or what if in the next version of Rock Band had a Jethro Tull piece and wanted to include a flute? These examples are just a few of the many possible uses of breath as a control. We decided to use the XNA framework to explore development in this area. We modified an Xbox controller to include a pressure sensor to sense how hard the user is breathing. We have 3 demos that utilize the ability of the controller to measure breath.
