This proposition for a system of intelligent artefacts is called PiA short for 'perceptive intelligent audio'. The person can directly interact with the music: she interacts with the actual sound. To describe this proposition, it is placed in the context of a home environment.
“When I come home from work, Sjors is often already at home. He, without exception, is listening to music. He can use different wirelessly connected devices to play the music from. The location of the device at first determines the location of the sound body. When Sjors uses his smartphone or tablet to play music from in the kitchen, the music starts playing in the kitchen. When I enter the house, the sound body will shift its focus to this new person (me). As the social situation changes, the volume will adjust to a level appropriate for conversation. The music shifts its focus to me and will move along through the living room to the kitchen, where Sjors is preparing dinner. The activity lures the sound body to the kitchen. We have an open kitchen and when one of us moves to the living room, the sound body adjusts its position and size, so that the music plays in both the kitchen and living room, possibly at different volumes.
Later that day, I walk out of the living room. The sound body has the urge to follow me. However, if I do not actively lure it along, it will not move too far away from Sjors. When I shortly engage in an active interplay with the sound body, I can lure it along with me. Moving too far away from its initial position, where there is still activity, the system creates two sound bodies. Activity, such as closing the door behind me, will make this split more abrupt. We now both listen to the same music in different locations of the house.
Of course, it can also be that I would like to play different music. When I take a device to play music along with me, I can play different music in different areas of the house. The location of the device contextualises its use. Although the speakers are all connected to the same system, I can play different music over each speaker. In other words, different sound bodies can play different music. Upon returning to the living room, the new sound body I created likes to follow me along. However, the music that Sjors plays in the living room overrules, as it has been playing for a while and was turned on in this area of the house. I can now change the music, but have to interfere through direct control of the smartphone or tablet from which the music is played. This again seizes on the contextual qualities of the physical control. The sound body that I was listening to before will turn off, as it does not detect any activity anymore.”
There will be a concept video of PiA available soon. The video below shows Surfacing Sound. This artefact supports the proposition.
