Further Analysis and Recommendations
The tasks set for our group of users where specifically aimed at
the projectors remote control and on screen graphic user interface,
this was primarily due to the projector being mounted out of the reach
of most users. They where aimed towards achieving what would be
simple every day interactions involving the projectors remote control
and graphic user interface, ranging from volume control to language
and display settings.
The main problems encountered by the majority of our users all
revolved around GUI navigation and selection via the remote control.
In the majority of cases navigation controls took time to learn
and become comfortable with, before tasks could be attempted.
Despite the very ergonomic positioning of the thumb button control; it
was neither apparent to the user as to what it’s function was and had
no markings to indicate it’s function. The thumb interface is also the
same colour grey as the rest of the remotes more direct functions such
as volume control and appeared lost on the remote when compared
with the power and lazar pointer buttons, which are yellow in colour.
The selection aspect of the remote/GUI interface also posed the
problem of offering it’s users different operational modes whereby one
could select options by pressing the thumb navigation button itself or
by pressing the button the left of it to select options. This indecision in
design directly led to indecision in the user, many users where able to
select options but where unsure as to exactly how they where
achieving there goals, for some it a simple case of mash and hope.
The on screen GUI itself made an already poorly marked out
remote control setup even more confusing for our users to navigate
