A NEW HMI EVALUATION METHOD (MERIA) BASED ON PILOT'S MENTAL REPRESENTATIONS

Résumé

Continuous evolution of HMIs is necessary to keep operators in an optimal situation. In this context, we consider mental representations (MR) mobilized by operators as key elements for decisionmaking. Capturing and analysing these representations is not easy with existing tools. We propose a specific method (i.e. "MERIA" for Mental Representation Impact Analysis). Our case study focuses on a group of first officer (Airbus A320) in a dynamic situation with high time pressure. We are interested in cases where the HMI generates MRs that are inconsistent with the situation, resulting in a discrepancy between the prescribed activity and the actual activity. The goal is to identify the link between erroneous MR and the interface that created them. Our modelling structure allows us to create this link and place it in a proper temporal context. We observe that the constitution of the MR is different from one subject to another. However, invariants in the appearance of some erroneous MR make it possible to attribute the causality to an interface element well-defined in space and time. Thus, this analysis allows us to offer recommendations for HMI design to improve decision making. Our results show that the improvement does not lie in a drastic modification of the interfaces. Rather is allows a synchronization of the data coming from the cockpit with the pilot's MR of those data. Introduction We only observed the co-pilot activity. They intervene in a dynamic, uncertain, risky situation and they must make multiple decisions under the pressure of real time to achieve their performance objectives (Graziani et al., 2016). In the context of the cockpit of an Airbus A320, our objective is to determine which interfaces allow the co-pilot to build a good mental representation of the situation and which ones do not. In complex environments, HMIs and co-pilot cognitive activities can be evaluated in multiple ways. The methodologies we are interested in are those that aim to jointly evaluate the efficiency of the interface and it's use by the operator. There are various categories of methods (Stanton,
