Abstract
This paper presents the qualitative analysis
methodologies and the results of an experiment aimed at
evaluating the usability of Ecological Interface Design
(EID) in nuclear power plant operation. The experiment
carried out at a full scale simulator in 2005 was a
collaborative effort between Halden Reactor Project
(HRP), University of Toronto, and VTT Technical Research
Centre of Finland. HRP and University of Toronto were
responsible for display and experimental design, and
statistical analysis. The simulator facilities were
provided by HRP. VTT contributed by participating on data
collection and by conducting qualitative analysis of
operator performance, operators' ways of acting, and user
experience. According to our results the connection
between display type and effectiveness of reaching good
process outcome is not straightforward: no significant
differences in performance outcome depend on display or
scenario type alone. However, it was found out that
display type can encourage good ways of acting, which,
depending on situational demands, can realize as good
outcome. The analysis of the ways of acting and user
experiences confirmed that EID supports fast detection
and functional thinking, and although the operators did
not fully master the use of EID after a short period of
training, they saw its potential in process control. In
conclusion, depending on the particular demands of the
situation, different kinds of information features of
displays become critical from the point of view of
performance outcome. Diversity is therefore a reasonable
principle in design.
