What material and method could I use to record a usability test in real situation?
I have to test some single user of an interface at their office desk, as they normally use it, without constraining them in any way. They can answer the phone, ask a coworker something, put a post-it on their screen if they usually do it (and yes, they actually do it).
I have no space to install a huge camera nor install monster software on their computer, which cannot support a huge ressource eater like Morae.
EDIT: If someone have any experience of such "ethnologic conditions," I will be intersted to know about the best methodology for collecting observation data: "tagging" notes method during the test, talk aloud method (and next data analysis)...
