_This is a “design brief”:http://www.nearfield.org/2007/05/touch-design-briefs, one of many themes that the Touch project is investigating._
With increasingly ubiquitous wireless networks the physical world is becoming layered with a spectrum of radio waves. These fields range from massive GSM, 3G and DVB cells, through to household sized wifi and bluetooth networks, to tiny RFID and NFC bubbles. Each of these invisible bubbles offers functions or services that can be accessed from various devices. When inside the appropriate field mobile phones may be able to carry a voice call or pay for a subway ticket, laptops can transfer data, while smart cards can authorise access or payments.
_What does the increasingly radio-saturated landscape – and our reliance on wireless infrastructure – mean in our everyday use of applications and services? Can we use fields as a material for creative purposes?_
This is a central issue for ubiquitous computing where wireless functions or services are embedded – invisibly – into the environment. For a user, knowing what kinds of fields are available and knowing what kinds of functions, applications or services they offer may be a critical usability problem in the near future. If certain fields become critical for our use ubiquitous functions or services, how can we cope with the edges, seams and failures? Do we need to increase the usability and awareness of various radio fields?
Can we introduce certain kinds of visibility back into ‘invisible computing’? How should we visualise the available options? Should we represent them technically, according to applications or services, or should we visualise the kind of information or risk involved in the interaction?

The work of “Matthew Chalmers”:http://www.dcs.gla.ac.uk/~matthew/DCS/Welcome.html on _seamful_ design is relevant, particularly: “Seamful Design and Ubicomp Infrastructure”:http://www.dcs.gla.ac.uk/~matthew/papers/ubicomp2003HCISystems.pdf: _”In this paper, we discuss taking a ‘seamful’ design approach to ubicomp systems. Some features that we designers usually categorise as infrastructure problems may, to users, be useful interactional features. Examples include the edges and gaps in 802.11 coverage, and the patterns of where one can and cannot get GPS positioning.”_

Because it is possible to simultaneously ‘ping’ the cell phones of thousands of users – thereby establishing their precise location in space at a given moment in time – these devices can be used as a highly dynamic tracking tool that describes how the city is used and transformed by its citizens.”_
