The interaction design of iBeat (2010) follows and explores assumptions regarding the potential of body movement, cf. also Wii, Nintendo, all of them revolving around issues of a more natural and richer interaction, enabling direct expression in real-time and allowing to pacing yourself. iBeat uses the accelerometer of the mobile device to create drumbeats. The accelerometer included in the iPhone, enables one to respond to rotation around three axes X, Y and Z. The iBeat prototype provides a configuration interface, which allows the user to choose four out of six different instruments and assign them to four different movement directions.
The increased body movement suggests an enhanced engagement of the musician. Moreover, stimulating the musician to perform dance movements, we assume that the interaction supports emotional experience. However, most important for our further studies we found the behavioral transformation happening throughout the process of interaction and related to that the transformation of the device.Hajinejad N.; Grüter B.
