prompted the user to explore the functionality of both the remote
control and the integrated menu.
The users were each given 11 individual goals or tasks to
achieve using whatever method they felt appropriate. To make the
users feel like they were carrying out tasks they might find in the real
world, the questions contain role-play where the user is asked to
respond to a specific simulated situation, such as a French delegation
arriving in the college and requiring the language to be changed on
the projector interface. The duration of the average evaluation took
between 5 and 10 minutes including the introduction, task completion
and debriefing.
The task list itself was kept as brief and concise as possible. The
actual tasks were deemed to be representative of the typical everyday
user. The tasks are listed below.
1. Please turn on the projector.
2. Once the projector has started up, utilise the integrated laser
pointer on the remote control, and please use it to point at
something on the screen.
3. The volume on the projector needs to be adjusted, please access
volume control and raise the volume.
