Abstract
In order to provide helpful proposals for future redesign of insulin pump interfaces, a study was carried out to investigate the expertise difference between novice users and expert users when interacting with a simple user interface of insulin pumps. In this study, two user groups with 13 participants in each, evaluated an insulin pump interface on a computer demo in usability tests. The results showed there was no significant difference between the novice users and expert users regarding the task completion time and the number of failures in performance. As for the cause of failures, the novice users showed weakness in domain knowledge, while the expert users showed weakness in task knowledge. No significant difference was shown on users’ satisfaction between the two user groups. The results also implied that the novice users elaborated their redesign suggestions in a deductive and summaric way, while the expert users proposed suggestions in an inductive and thorough way.
