Sydney.
The next session at Mobile Media 2007 starts with my paper, co-authored with Rachel Cobcroft, Jude Smith, and Stephen Towers (PDF available here, Powerpoint here).
Kathleen Cumiskey is the next speaker. She notes that there is significant research on the actual use of mobile phones, but less on the meanings users themselves ascribe to such use; her research focusses on such use stories, instead. The use of mobile phones during face-to-face interaction renders remote others present, while denying the presence of those physically present. This is related to the psychological idea of 'mattering': in the process of mobile phone use, remote participants are identified as mattering, while physically present participants are shown to matter less.
