The analogue equipment and one-way mirror made my office feel like a lab (which I prefer), but recording quality was poor. So it is time for a larger, separate space, Tobii eyetracker and Morae software. The new set up captures more, higher quality recordings and keeps my office tidy.
The old kit was nevertheless very useful. As this videoclip shows, design flaws in a user interface have nowhere to hide, not even behind a poor recording!
