Intermediate Interaction in Traffic

Based on an ethnographic study of community road signs, we argue that mobile location aware systems fit somewhat with an abundant practice where private persons make and post signs along the roads. People who live along roads have various reasons, and investigate in various ways, to communicate with passing drivers. Even though these road signs are mostly used for interaction outside of the neighborhood community, they fill an important role to sustain those communities. Our fieldwork reveals that the available mobile location based systems need to be adapted both for such communication, as well as for the particularities of reading signs when moving along a road at high speed.
