In the lab and out in the wild

In this paper we discuss a pilot usability study using wireless Internet-enabled personal digital assistants (PDAs). We compared usability data gathered in traditional lab studies with a proxy-based clickstream logging and analysis tool. We found that this remote testing technique can more easily gather many of the content-related usability issues, but device-related issues are more difficult to capture.
