Mobile rhythmic interaction in a sonic tennis game.

This paper presents a game for mobile devices which simulates a tennis match between two players. It is an audio-based game, so the majority of information and feedback to the user is given through sound instead of being displayed on a screen. As users are not requested to keep their eyes on the display, the device can be used as a motion-based controller, exploiting its internal motion sensors to their full potential. The game aims to be useful for both entertainment and educational purposes, and enjoyable both by visually-impaired (the main target audience for audio-based games nowadays) and sighted users.
