This paper is a reflection on the role of levels of automation in medical device usability. The reflection is based on a comparison of results from two independent usability evaluations on dialysis machines (one newer and one older). Usability problems were found that could be traced back to the use interface design and automation level of the machines. The comparison showed that there was a difference in usability problem types at different levels of automation and a conclusion was that the usability aspect becomes even more important as the level of automation increases.
