Sonic Tennis: A Rhythmic Interaction Game For Mobile Devices

Stefano Baldan, Amalia De Götzen, Stefania Serafin
2013 Zenodo  
This paper presents an audio-based tennis simulation game for mobile devices, which uses motion input and non-verbal audio feedback as exclusive means of interaction.  ...  The game aims to be entertaining but also effective for educational purposes, such as ear training or improvement of the sense of timing, and enjoyable both by visually-impaired and sighted users.  ...  As a matter of fact, the sound parameters used to modulate the audio signals are strongly related, if not directly mappable, to musical features and concepts.  ...
