Any kind of research interviews can be conducted online-- but you have to be able to create a defensible rationale for the choices you make. I hope to help with that process; a big focus in the book is on alignment of theory, epistemology, methodology and method. Alignment is important in any research design but essential for a proposal that includes e-research. Why? Because it will undoubtedly receive more scrutiny. (See the new discussion thread for more about this.)
That said, some types of interviews work best in some types of technologies-- and that will be our focus next week.
Ability to record and save the interview is crucial so that is a decision point when you make your selection. Some options allow you to record, others require use of another tool that records whatever is happening on your desktop. Nellie and (the other) Bronwyn have suggested Audacity and Tipcam. My own feeling is that the fewer different kinds of technology tools, the fewer chances there are for things to go wrong.
In the scope (no pun intended!) of this seminar we will of course not be able to go into every aspect-- such as analysis of visual data-- but I hope it is a start!
