A human reliability analysis (HRA) is defined as "any method by which human reliability is estimated” [1, p. 301] and generally
consist of three parts: 1) identifying possible human errors and contributors, 2) model human error, and 3) quantify human error
probabilities. Many HRA methods quantify human error probabilities through the use of performance shaping factors (PSFs) that
increase or decrease these probabilities. One of the factors that are often evaluated is the quality of the human machine interface
(HMI) and how it affects performance. However, as evaluating HMI can be a complicated task the descriptions found in HRA
methods are often not sufficient to perform the evaluation. This problem has increased lately as most current HRA methods are
based on classical non-computerized control rooms creating a mismatch between the descriptions and the real world [2]. In this
paper different HMI evaluation methods are discussed in terms of their usability in situations where the descriptions provided in
HRA methods are not sufficient.
