Abstract:
In this paper, we introduce an implementation for detailed
monitoring of user actions on web pages. It addresses the
problem that the log data recorded by standard web servers
is not sufficient for the tracking of users on AJAX websites,
e.g. to conduct a usability test. Using standard web technologies,
our HTTP proxy can record very detailed usage information,
such as mouse movements, clicks, key presses and
scrolling, together with the exact HTML DOM tree objects
involved. As we show in several case studies, the tracking
also works across multiple websites, none of which needs
to be under our control. This approach is much less invasive
than previous efforts: The test person does not need to
install software on her computer, and in certain operation
modes, no configuration changes at all are required on her
computer. Our research indicates that if the technology described
in this paper is employed, arbitrary visitors of a website
are more likely to take part in a usability test offered by
that site – this facilitates recruiting test participants over the
Internet.
