* values have been converted to other end of Likert scale due to negative
phrasing of the survey question.
Table A2. Likert survey results of interface testing
After completing the Likert portion of the survey the participants answered
three open ended questions followed by a structured interview.
a. Open Ended Questions
The questions asked what the participants liked the most
about the interface, what they liked the least about the interface and if they had
any ideas for improvements.
• What did you like the most about the interface?
The participants liked that there were not too many buttons and that
it was easy to understand what the buttons do.
• What did you like the least about the interface?
What the participants disliked had more to do with the actual
content than the interface. One participant disliked the blurry map; others wanted
the devices to be fully functional. Unfortunately, due to the nature of the
prototype device functionality could not be implemented.
