particular operational style was adopted. However the apparent and
obvious lack of a user-friendly interface has led to changes in our
prototype; aimed towards effecting major improvement towards easier
navigation and control of the onscreen GUI. Changes will be
implemented on the remote itself as well as the projected GUI.
Possible Solutions
The first change we would make to the overall design of the
projector would be to address the shortcomings of the IR sensor
located on the projector. It has become apparent through our sessions
that a limited IR sensor radius greatly affected our users interaction
with the projectors GUI, in that a sluggish and repetitive. Upon
consulting the projectors user manual the actual recommended ark or
radius for successfully using the remote was mere 60 degree’s from
the IR sensors at the back and front of the projector. In our survey not
one user opted to use the front IR sensor. We would place more IR
sensors on the projector itself enabling complete freedom of movement
to the user by providing a 360-degree sensor field. Below is the user
manuals diagram of the IR sensors filed of operation.
