Article
Full-text available
The processes underlying team effectiveness can be understood by analyzing the temporal dynamics of team communication sequences. The results of such analyses have shown that the complexity of team communication is associated with team performance on task-related variables, and hence communication complexity statistics have been proposed for use as...
Article
Automatic prediction of team performance and workload plays a crucial role in team selection, training, evaluation, and re-training processes. This study investigated the potential of using voice analysis of team-based communication for predicting team workload (TW) and team performance (TP). Both the TW and TP categories were labeled objectively....
Article
Effective team performance often requires that individuals engage in team training exercises. However, organizing team-training scenarios presents economic and logistical challenges and can be prone to trainer bias and fatigue. Accordingly, a growing body of research is investigating the effectiveness of employing artificial agents (AAs) as synthet...

This study investigated the effects of using a cell phone to retrieve and send text messages on the driving performance of young novice drivers. Young drivers are particularly susceptible to driver distraction and have an increased risk of distraction-related crashes. Distractions from in-vehicle devices, particularly, those that require manual inp...
Article
Previous research has shown that size-dependent errors in time-to-contact (TTC) judgments can be attenuated when approaching objects are familiar to the observer and have a known size. We describe two experiments that show that the effect of size on relative TTC judgments can be modeled on observers' reliance on the instantaneous optic expansion ra...
Article
Objective This research aimed to investigate the relationship between gaze behaviour dynamics and operator performance. Background Individuals differ in their approach when learning a new task often resulting in performance disparity. During training some individuals learn the structure and dynamics of the task and develop a systematic approach, w...
Preprint
Simulation-based training utilising visual displays are common in many defence and civil domains. The performance of individuals in these tasks depends on their ability to employ effective visual strategies. Quantifying the performance of the trainees is vitally important when assessing training effectiveness and developing future training requirem...
Conference Paper
Full-text available
In many team-based activities, members search for information to gain situational awareness and thereby structure their own behavior. The extent to which members are coupled and in control of their surrounding environment can be accessed via the fluctuations of their searching behaviors. To facilitate prospective control, assistive technologies suc...
Conference Paper
Full-text available
Many everyday tasks require individuals to work together as a team to achieve a task goal. For many complex or high-stakes multi-agent activities, team members are required to participate in simulated training exercises to develop the task- and team-work (coordination) skills needed to maximize task performance. Such training, however, can be both...

The ability to maintain appropriate gaps to objects in one's environment is important when navigating through a three-dimensional world. Previous research has shown that the visual angle subtended by a lead/approaching object and its rate of change are important variables for timing interceptions, collision avoidance, continuous regulation of braki...
Article
There is currently a great deal of interest in the problem of driver distraction. Most research focuses on distractions from inside the vehicle, but drivers can also be distracted by objects outside the vehicle. Major roads are increasingly becoming sites for advertising billboards, and there is little research on the potential effects of this adve...
Article
Many interceptive actions involve interactions with objects that are familiar to the observer and have known sizes. Two experiments investigated how known size influences observers’ perception of time-to-contact (T c). Participants made T c judgements of objects that were either ambiguously sized, standard-size in identity/familiarity, or off-size...
Article
Hazard perception is a critical skill for road users. In this study, an open-loop motorcycle simulator was used to examine the effects of motorcycle riding and car driving experience on hazard perception and visual scanning patterns. Three groups of participants were tested: experienced motorcycle riders who were experienced drivers (EM-ED), inexpe...
Article
Driver drowsiness is a significant contributing factor to road crashes. One approach to tackling this issue is to develop technological countermeasures for detecting driver drowsiness, so that a driver can be warned before a crash occurs. The goal of this review is to assess, given the current state of knowledge, whether vehicle measures can be use...
Article
This study reports an experiment that compared the hazard perception abilities of experienced and novice motorcycle riders using an interactive, closed-loop, simulator. Participants (n = 49) were categorized into four groups: experienced motorcycle riders with full driver licence, inexperienced motorcycle riders with full driver licence, novice mot...
Article
Full-text available
Throughout Australia and much of the world, roadside advertising by means of billboards is commonplace -but potentially distracting for drivers. As yet, there is little research into which specific aspects of driving performance might be affected by the presence of such advertising billboards. To investigate this, the present experiment used the 'c...
