Speculating the new meaning of the public space in our time of ubiquitous computing, this project aims to search and produce the full ranges in the possibilities of contemporary nomadic life, including new definitions of privacy and publicity. One of the renowned Technology thinkers, Don Idhe says the Embodiment relationship, that extended the body to the technology; Hermeneutic relationship, that after the embodiment creates a new text and new phenomenons; Background relationship, that is a technosphere and ubiquitous world. AU-Units are layers of augmented realities: everywhere, a thing that thinks and seamlessly adapting.
First, city planning is no more pre-planned or master-planned functional divisions. Unlike modern planning, unseen thing and its accessibility are the new base of the urban design and its further evolution. Taking the city of Basel in Switzerland, one of the organic cities that later-modernized, augment urbanism overlays a new layer of AU-Units, which are the terminals or workstations to augmented reality. AU-Units are the post-functional spaces that are adapted by the users to produce different functions and extend to the technosphere. AU-Units include housing that is fully public but also can be fully privatized. AU-Units is no more static, based on the fix-reference point. It is now free to extend, both physically and virtually, following the needs and changes of the users. Another version of AU-Unit, AU-Mobile extends its physical boundary and has mobility by reconfiguring the rigid and limited possibilities of modern trains. Especially, the city of Basel is a tri-national city, bordering with Mulhouse, France and Freiburg, Germany, which is one of the major points of the European rail network. AU-Mobile is augmented; fully public that can be fully privatized while the physical boundary is being trans-ported.
