Information overload is a severe problem for human operators of large-scale control systems as, for example, encountered in the domain of road traffic management. Operators of such systems are at risk to lack situation awareness, because existing systems focus on the mere presentation of the available information on graphical user interfaces—thus endangering the timely and correct identificatio...

There has been much activity over the past two decades in developing conceptual models under the titles of data fusion and situation awareness. In this paper we will explore the two most popular models and show how they complement each other in developing an overall framework for situation awareness. We will also demonstrate how this framework has been applied to a sample “monitoring” problem.

Despite the increasing demand for service robots, considerable challenges remain to be solved before these robots can be ubiquitously employed in personal households. To this date, autonomously operating robots lack the flexibility to react appropriately in unforeseen situations. At the Human Factors Institute of the Universität der Bundeswehr München, a multi-disciplinary research group of psy...

BACKGROUND Studies show that implementing huddles in healthcare can improve a variety of outcomes. Yet little is known about the mechanisms through which huddles exert their effects. To help remedy this gap, our study objectives were to explore hospital administrator and frontline staff perspectives on the benefits and challenges of implementing a tiered huddle system; and propose a model based...

Disorientation is common for endoscopists performing colonoscopy. The objectives of this study were to examine how endoscopists acquire and maintain spatial awareness or situation awareness (SA), and how SA varies as a function of available perceptual cues, and as a function of the different segments of the colon. Retrospective analysis of verbal protocols from 11 colonoscopy procedures was con...

Trust is a social phenomenon that impacts the situation awareness of individuals and indirectly their decision-making. However, most of the existing computational models of situation awareness do not take interpersonal trust into account. Contrary to those models, this study introduces a computational, agent-based situation awareness model incorporating trust to enable building more human-like ...

This paper discusses a computational model of situation awareness (SA) for military command and control in complex battle situations. Cognitive modeling is a research method that does not forgive vagueness. How do military commanders create awareness in a highly complex and uncertain world? The model described in this paper simulates computationally some of the cognitive operations performed by...

threat assessment in the computer networks of organizations can reduce damage caused by attacks and unexpected events. data fusion models such as the jdl model provide efficient and adequate sensors to gather the right information at the right time from the right components. this information then is refined and normalized to provide situational awareness and assess events that may be intended a...
