Intuitive Gestural Interfaces / Adaptive Environments and Mobile Devices / Apps.: Playing Music and the Musical Work as a Role Model for Personalized Gestural Interaction in Social Environments.

Generally mobile devices are seen being transportable, but they are moveable too - their ability to detect body-motions is often ignored. Based on theories of the origin of music and of playing music, the instrumentarization / mediatisation of expressive sounds and behaviour become role models for intuitive emotional / personalized interfaces in social interaction. The ability to detect motion make mobile devices a kind of extension of the expressive body-motion to create expressive sounds; the ability to share these sounds in social interaction make mobile devices tools to create collective "sounds in progress" and collectivize the agents. Based on these theories of music being emotional communication in social interaction and these abilities of devices being "mobile" various solutions of emotional communication by sound creating a new kind of "pop-music" as "playing music" immediately by the body is introduced. Based on experimental studies of musical and gestural interaction the use of mobile devices and apps. (creating those new kinds of (pop-)music) in music-education/-therapy or measuring emotional behaviour in marketing research is shown. Finally intuitive adaptive gestural interfaces / (living-)environments and mobile devices / apps. in everyday-life of a hedonic culture are introduced and discussed.
