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 contentrelated usability issues, but device-related issues are more difficult to capture. Keywords Remote Usability Testing, Clickstreams, Log File Visualization, Usability Evaluation, Mobile Internet.
