“…The starting point of developing new UI concepts was the set of deficiencies that we have identified in our previous work concerning SA (Van Doorn et al 2015. The objective was to generate proper underpinning theories for UI design concepts that can efficiently contribute to the enhancement of operators' SA.…”

There has been an increase in the amount and complexity of traffic on Dutch inland waterways. Traffic management shifted from local traffic control to corridor traffic management. Due to these changes, operators in nautical traffic management centers experience difficulty to gain and maintain sufficient situation awareness. In our previous research, three groups of deficiencies of current situation awareness support have been identified. To overcome these deficiencies, a theoretical framework for information engineering user interface concepts was developed and used for designing three interface concepts. A coherent, an integrated and a context-dependent adaptable user interface were designed and implemented as testable prototypes. To support the process of information engineering, we combined user-centered design techniques with the formalism of set theory, directed graphs and semantic networks. From a methodological point of view, these proved to be useful both in conceptualization and implementation of the concepts. The usability of these concepts was tested in a simulator environment. The results show that the implemented prototypes represent an important improvement compared to the traditional interface solutions currently used by nautical traffic management operators. However, it was recognized that the coherent user interface implementation still suffered from a number of deficiencies. The context-dependent adaptable user interface was evaluated most positively.

Nautical traffic management in The Netherlands is shifting from local traffic control to corridor traffic management. Current traffic management systems do not sufficiently support operators in perceptual and cognitive process to interpret and understand the large amounts of information needed for corridor traffic management. Newly developed user interface concepts aim to overcome deficiencies of current interface designs that insufficiently support situation awareness assessment. The effects of these new user interfaces, however, are insufficiently known due to the intricate relations between situation awareness, task performance, and workload. The objective of this study is to evaluate the effects of the three previously developed user interface concepts on operators' situation awareness, task performance, and workload to gain better insights into the benefits and limitations of the user interface design concepts. The effects were tested in a simulator environment. The results show that user interface features of an integrated user interface allowed operators to apply more effective information processing, which resulted in better task performance. Features of a context-dependent adaptable user interface triggered proactive behavior of operators, which resulted in better task performance for tasks in which operators require insight into future activities of the elements in the environment.

Abstract:This paper presents an analysis scheme which aims to support a systematic study of required situation awareness (RSA). This scheme supports identification of deficiencies of support for situation awareness (SA). Information needs are goal and task dependent and can be defined using existing cognitive task analysis (CTA) methods. RSA, however, is a subset of information needs and depends on the interaction between goals, tasks, system factors and individual factors. The analysis scheme has helped to identify that the current methods to define RSA do not support a distinction between information needs and RSA. The scheme was trialled in a nautical traffic management context as an extension to existing CTA methods. The research activities necessary to study RSA and to identify deficiencies of current support for SA in nautical traffic management context were applied. The study showed that the research set-up designed through application of the analysis scheme helped to define RSA, and that RSA is considerably context and operator dependent. Future research will focus on the potential for context-aware adaptable interface solutions to allow for RSA dependent information visualisation.Keywords: man-machine interactions; MMI; required situation awareness; information needs; situation awareness requirements; analysis scheme; deficiencies; nautical traffic management; information intensive task environment; informing.Reference to this paper should be made as follows: van Doorn, E., Rusák, Z. and Horváth, I.
