A Mobile Radicals Project

If computer applications are to become pervasive then they must become part of the everyday fabric of our lives and will provide users with the ability to interact with objects and places within both the real and virtual worlds. One trait of human behaviour in the interaction with objects appears to be an inherent passion for leaving our mark on these objects. In our current society, this is most readily evident through graffiti spray-painted in public places. To some, this is urban art reflecting the communities in which it resides, whilst to many it is an act of vandalism.

SprayCan graffiti divides communities and generations in terms of how it should be dealt with in terms of either complete acceptance or punitive action. In MobSpray we have developed a system that tries to bridge the divide as it both provides writers with a means of tagging their environment, using mobile phones and RFID tags, whilst minimising the physical effects to the landscape for the communities where it resides.

Writers’ tags are deposited, and collected, from a database operating on a central server using a GPRS connection initiated by a Java application on a Nokia 5140 with an in-built RFID reader. These tags are currently displayed on the writers phone but the system is being evolved so that they can be projected on walls in urban landscapes.
