Background: Wearable activity trackers are promising as interventions that offer guidance and support for increasing physical health-focused tracking. Most adults do not meet their recommended daily guidelines, wearable fitness increasingly cited having great potential to improve the levels of adults.

A fundamental challenge in studying cognitive systems context is how to move from the specific work setting studied a more general understanding of distributed and support it. We present series field studies that illustrate one response this challenge. Our focus was on nuclear power plant (NPP) operators monitor state during normal operating conditions. at two NPPs with different control room interfaces. identified strong consistencies respect factors made monitoring difficult strategies...

Objective: We determine whether an ecological interface display for nuclear power plant operations supports improved situation awareness over traditional and user-centered displays in a realistic environment. Background: Ecological design (EID) has not yet been fully evaluated with real operators facing scenarios. Method: were alongside “advanced” full-scope simulation. Licensed used the scenarios that either had procedural support or did have support. All three their ability to operator...

Autonomous driving is on the horizon. Vehicles with partially automated capabilities are already in market. Before widespread adoption however, human factors issues regarding need to be addressed. One of key how much drivers trust systems and they calibrate their reliance based experience. In this paper, we report results a survey conducted Tesla about experiences two advanced driver assistance systems, Autopilot Summon. We found that have high levels Trust decreased age for but not Drivers...

As autonomous driving emerges, it is important to understand drivers' experiences with cars. We report the results of an online survey Tesla owners using two features, Autopilot and Summon. found that current users these features have significant experience, high self-rated computer expertise care about how automation works. Surprisingly, although failures are extremely common they were not perceived as risky. The most commonly occurring included failure detect lanes uncomfortable speed...

Increasingly, artificial intelligence (AI) is being used to assist complex decision-making such as financial investing. However, there are concerns regarding the black-box nature of AI algorithms. The field explainable (XAI) has emerged address these concerns. XAI techniques can reveal how an decision formed and be understand appropriately trust system. still may not human-centred support human adequately. In this work, we explored domain knowledge, identified by expert makers, achieve a...

Abstract Artificial General Intelligence (AGI) is the next and forthcoming evolution of (AI). Though there could be significant benefits to society, are also concerns that AGI pose an existential threat. The critical role Human Factors Ergonomics (HFE) in design safe, ethical, usable has been emphasized; however, little evidence suggest HFE currently influencing development programs. Further, given broad spectrum application areas, it not clear what activities required fulfill this role....

Most palliative care research about caregivers relies on reports from spouses or adult children. Some recent clinical have noted the assistance provided by other family members and friends.This population study aims to define people who actually provide at end of life.A South Australian conducted an annual randomized health survey (n=23,706) over a 7 year period. A sample was obtained self-identifying had someone close them die 'expected' death in last 5 years (n=7915). Data were...

Autonomous vehicles (AV) may be able to show visual displays on their external surface support pedestrian communication with the AV. Pedestrian crossing at uncontrolled locations is safety-critical and clear between AV important in this situation. However, research date has not been how should communicate pedestrians. We designed two sets of warnings AVs based perception warning urgency. Each set consisted three that differed color flashing pattern indicated distinct safety-related...

Digital mobile technology presents a promising medium for reaching young adults with smoking cessation interventions because they are the heaviest users of this technology.The aim study was to determine efficacy an evidence-informed smartphone app cessation, Crush Crave (CTC), on reducing prevalence among adult smokers in comparison self-help guide, On Road Quitting (OnRQ).A parallel, double-blind, randomized controlled trial 2 arms conducted Canada evaluate CTC. In total, 1599 (aged 19 29...

Computer displays are being designed for increasingly larger industrial systems. As the application domain scales up, maintaining integration across different kinds of views becomes more challenging. This paper presents results a study three approaches to based on spatial and temporal proximity related information objects. The used evaluation was simulation an industry-scale conventional power plant. All were ecological developed using abstraction hierarchy analysis. Views integrated in...

Cognitive work analysis (CWA) as an analytical approach for examining complex sociotechnical systems has shown success in modelling the of single operators. The CWA incorporates social and team interactions, but a more explicit aspects can reveal information design. In this paper, Team is explored to understand teamwork within birthing unit at hospital. models are derived from theories leverage existing approaches analyse interactions. explained contrasted with prior CWA. does not replace...

Background: Tobacco use remains the number one cause of preventable chronic disease and death in developed countries worldwide. In North America, smoking rates are highest among young adults. Despite that majority adult smokers indicate wanting to quit, this age demographic have yet decline. Helping adults quit continues be a public health priority. Digital mobile technology presents promising medium for reaching population with cessation interventions, especially because heaviest users...

Introduction: The burden of chronic diseases is rapidly increasing worldwide. In Australia rural populations have a greater disease. Chronic are largely preventable with diet as key risk factor. With respect to diet-related disease, dietary may be due poor food access, namely, availability and/or the high cost healthy food. It likely that access an issue in areas. Objective: To assess south-west (SW) Victoria, Australia. Methods: A total 53 supermarkets and grocery stores 42 towns...

The Fresh Kids programme utilized the Health Promoting Schools (HPSs) framework to design a whole-of-school, multifaceted intervention targeting specific behaviours promote healthy eating and reduce risk factors associated with childhood obesity. aim of was evaluate effectiveness HPS increase fruit water consumption among primary school-aged children over 2-year period. study an interrupted time series. Four schools in inner west Melbourne, Australia, participated intervention. Baseline data...

Despite much having been written, both nationally and internationally, about rural suicides, no one in Australia knows either the number of residents on farms or suicide rate for this group people. This paper seeks to determine South Australia, along with rate.A retrospective audit review files suicides completed between 1 January 1997 31 December 2001 was undertaken Australian Coroner's Office. There were 1033 cases examined sociodemographic details 380 explored detail.Estimating...

Today’s complex sociotechnical systems involve more than just single operators and often include rich team interactions. In this article, the authors explore cognitive work analysis (CWA), a method typically used for deriving design requirements to support operators, rework methodology into version that is intended show required successful collaboration. Team-suitable approaches are presented first two steps of CWA, domain control task analysis. These collected from past attempts model teams...

The pediatric intensive care unit (ICU) is a complex environment, in which multidisciplinary team of clinicians (registered nurses, respiratory therapists, and physicians) continually observe evaluate patient information. Data are provided by multiple, often physically separated sources, cognitive workload high, communication can be challenging. Our aim to combine information from multiple monitoring therapeutic devices mobile application, the VitalPAD, improve efficiency clinical...
