Information engineering for developing and testing coherent, integrated and context-dependent user interfaces

Abstract

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.

“…This method can effectively identify the degree of outlier of the data, which does not require Assume a specific distribution model. The specific steps of the density–based algorithm (LOF) include: finding each object in the data set, and calculating the minimum inclusion points of each object, the MinPts neighborhood, and the distance between each object; and calculating the local reachable density of each object to determine its locality Outlier factor, or LOF; the outlier object is determined based on the determined LOF threshold 29,30 …”

Effects of coherent, integrated, and context-dependent adaptable user interfaces on operators’ situation awareness, performance, and workload

“…In our previous work, we presented three UI concepts to better support N-ONM SA and task performance: (1) a coherent UI, (2) an integrated UI, and (3) a context-dependent adaptable user interface (Van Doorn et al 2017a). The coherent UI concept is the concept that is closest to current practice.…”

“…In our previous work, we designed and developed three user interface (UI) concepts to overcome deficiencies of current traffic management systems to increase operators' SA and to improve operators' task performance (Van Doorn et al 2017a). The three concepts are built upon each other.…”

“…We also found that operators did not experience deficiencies when working with the integrated UI. Despite an overall preference of operators for the context-dependent adaptable UI, this raised the question "whether using a context-dependent adaptable UI instead of an integrated UI will improve the SA of the operators to such extent that it warrants the consideration of the first one despite of the higher efforts and overheads of implementation" (Van Doorn et al 2017a).…”
