Summary:
This user expressed that she felt that the tasks set where hard
to complete. This could be due to her lack of previous experience with
such devices. Following our session despite the difficulties
encountered she expressed feeling more confident about using a
similar projector in the future. Remote and GUI interface despite it’s
flaws is picked up within a relatively short period of time, this is due
more to user interaction than design feature.
User Two
Task One: Please turn on the projector.
Once locating the IR sensor at the back of the projector, user powers
up the projector and is also aware of the warm up time.
Task Two: Once the projector has been started up, utilise the
integrated laser pointer on the remote control, please use it to point at
something on the screen.
User locates laser button easily.
Task Three: The volume on the projector needs to be adjusted, please
access volume control and raise volume.
No problems, user intuitively points remote to white screen instead of
IR sensor, this reflects the habitual element of remote control usage
associated with the television. One automatically points to the screen
and the IR sensor located under it. User identifies mistake quickly
changes target to the projectors IR sensor located to the rear.
Task Four: It is necessary to set up the projector for use by a French
delegation later tonight. Please attempt to change the interface
language to French.

buttons until it worked. In pressing both the central thumb stick the
button to its left he is unsure as which button worked.
