On the 3rd of May I will present the paper “A study of Emergency Response Work: Patterns of Mobile Phone Interaction” on the Distributed Cognition track at the CHI2007 conference in San Jose, US. This paper is co-authored with Urban Nulden. This is my second presentation of a research paper at CHI and I am looking forward to attend the various tracks. This paper presents findings from a study of emergency response work at two chemical incidents and how mobile phone interactions in such work could provide new ways of distributing and sharing information.
