Analysis and Design
User Interface Guidelines
The old therapist’s UI is a standard UI for all VEs. It is consistent across all the VEs that
have been created, makes it becomes poor in design. For example, the map of the airplane
seat is much more smaller than the place given to it, so there is a big blank space beside this
map. In contrary, the widgets for controlling the VEs are squeezed into small container. The
old therapist’s UI is also not taking into consideration size of frequent used and useful
controls. The therapist rarely uses the note feature, but SUDs recording is used often. The
size of the note text box is very big whereas the SUDs chart is small. These kinds of
weakness in the old therapist’s are improved. Figure 3.12 shows the size comparison of the
note and SUDs recording features

Cognitive artifacts
It has already proved that providing the SUD recording and reviewing tools is really needed
for the therapist, but the historic data have not yet provided. The emergence of this historic
SUDs data is to track the history of patient’s treatment. The report printed after each session
will be put in the patient’s file, so the therapist can easily look the history of the patient’s
treatment progress.
