This paper examines the implementation of an automated W-CDMA microcellular deployment and coverage reconfiguration algorithm based on the concepts of Situation Awareness (SA). A deterministic microcellular propagation model (Citrus) is used to provide the detailed site-specific propagation data. An initial network deployment is performed over one square kilometre of central Bristol using the C...

This paper discusses the effects of tactile cueing on performance in a fixed base simulated helicopter hover task. Sixteens active-duty military helicopter pilots participated in a repeated measures two minute stationary hover test. Participants performed the hover task under four treatment conditions; tactile cueing (on/off) and secondary arithmetic task (on/ofT). Following each 2-minute hover...

Systems enabling to drive automatically are being introduced on the market. When using this technology, drivers are in need for interfaces which support them with supervision of the automated control. Assessment of Situation Awareness (SA) which drivers are able to gain while using such interfaces, is important. Based on comparison between SART and SAGAT measurement techniques within a simulato...

One of the key assumptions in Endsley’s three-level Situation Awareness (SA) model is the critical role of mental models in the development and maintenance of SA. We explored a prescriptive way of modeling this essential mental process of the fire incident commanders’ fire ground assessment. The modeling was drawn from the Fast and Frugal Heuristics (FFHs) program, given the strong parallels be...

A mobile ad hoc network is an important component in providing future military communication. To maintain information superiority and avoid unfortunate incidents, e.g. friendly fire, it is crucial for the network to provide a Situation Awareness (SA) service. In this paper we analyze if it is possible to combine the transmission of SA position information with the routing control traffic. We sh...

Situation Awareness (SA) is defined as the perception of elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future [1]. Lacking SA or having inadequate SA has been identified as one of the primary factors in accidents attributed to human error [2]. In this paper we present a probabilistic machine-lear...

The current study assessed the utility of measures of situation awareness (SA) and attention allocation for objectively describing telepresence. The concepts of SA and attention have been identified as cognitive constructs potentially underlying telepresence experiences. The motivation for this research was to establish an objective measure of telepresence and to further investigate the relatio...

Medication administration error remains a leading cause of preventable death. A gap exists in understanding attentional dynamics, such as nurse situation awareness (SA) while managing interruptions during medication administration. The aim was to describe SA during medication administration and interruption handling strategies. A cross-sectional, descriptive design was used. Cognitive task anal...

We developed an intelligent information visualization tool to enable public health officials to detect healthrelated trends in any geographic area of interest, based on Twitter data. Monitoring emergent events such as natural disasters, disease outbreaks, and terrorism is vital for protecting public health. Our goal is to support situation awareness (SA) for personnel responsible for early dete...

ZHANG, TAO. Using Measures of Situation Awareness to Characterize Mental Models in Inductive Reasoning Tasks. (Under the direction of Dr. David B. Kaber.) Mental models have been proposed in both the cognitive psychology and human factors literature. However, they have been applied for a variety of related but distinct representations. For system design and user training in practical applicatio...
