the actual evaluation process. This user was a female student with no
prior experience of operating a projector who was aged between 18
and 25.
The pilot study was identical to the actual evaluation in

in this particular evaluation. Please bear in mind that the room in
which the projector is located is constantly in use by other people. This
raised issues such as how to video the interaction of the user with the
projector without the video being affected by people passing by,
ambient noise and people talking. The fact that there were so many
people in the room appearing in shot could be very distracting.

to intimidate them. Only one video camera was used and a still camera
