Liminal Space is a design concept of urban space where technology enters symmetric relationship with people and environment. In Liminal Space, technology is promoted and invited to improve experience with the urban space through connecting the missing links between different scales of places from human body, through a building, neighbourhood to the whole city. 
Within this dissertation, I explore the concept of Liminal Space both from theoretical as well as practical sides, as theories often develop hand in hand with practical design research. The theoretical approach is founded in "Actor-network theory" (ANT) that redefines the relationship between people and other entities and the environment they share. Using ANT to promote technology to an egalitarian status with humans, however, is only a first step.
Within urban media design research we presently identify to main streams of approaches: "companion technologies" and "situated technologies". Liminal space brings together companion technologies in the form of by embedded interfaces residing close to our bodies and connecting them with data extracted from space by situated technologies.
Navinko is a digital artefact designed to demonstrate the liminal space experience and uses aural interface to generate music based on shared locations of interest. It re-purposes the information created for sharing on screens turning urban landscape of Tokyo into generated musical experience based around users' movement and situation context.
