Human factors of automated driving systems: a compendium of lessons learned by Francesco N. Biondi, Balasingam Balakumar Abstract: On-road deployment of partial automation and testing of vehicles with higher levels of automated driving systems have been ongoing for several years. Recent research partly confirms what we already knew about user interaction with automation in aviation, and, interestingly, adds relevant information to our understanding of human operators adoption of vehicle technology. In this study, we review key studies from the last quinquennial on driver interaction with partial and higher levels of automation, with the goal of providing a compendium for transportation professionals and legislators. In addition to providing a brief but necessary introduction of the Society of Automotive Engineers Taxonomy, we address research findings and human factors safety takeaways for partial automation. Our review shows that driver underload, lacking mental models, and driver training are key issues that merit further human factors investigation. In the latter part of the compendium, we also discuss recent findings and policy considerations on higher levels of automated driving systems. These include developing more transparent and comprehensive ways of reporting incidents and system disengagements, having protocols that help minimise safety risks during transitions of control, and implementing validation methods that help mitigate the safety risks of automated systems. Keywords: automated driving systems; ADSs; partial automation; Society of Automotive Engineers; SAE taxonomy; human factors; automation. DOI: 10.1504/IJHFE.2021.10036735
A new framework for optimisation and effectiveness of service operations approaches to reduce human errors in healthcare by Hadi Balouei Jamkhaneh, Reza Shahin, Maria Chiara Leva Abstract: Human errors in healthcare socio-technical systems can be a serious threat to patient safety. This study provides an integrated and systematic framework for assessing and optimising service operations approaches (SOA) that are effective in human errors reduction. For this, a pilot study was used to test the combination of three methods for a complete process to help identify ways to improve exposure to human error by selecting an optimal strategy. Based on experts opinions, we performed a risk assessment using failure modes and effects analysis for each human error and a risk priority number (RPN) was assigned for each failure mode. Next, a house of quality approach was applied to identify the impact that different SOAs may have on improving human errors in healthcare. Ultimately, in order to select the optimal SOA, a zero one goal programming model was used to consider simultaneously
resources limitations and the error reduction. Keywords: service quality; human error analysis; service operations approaches; SOAs; failure modes and effects analysis; FMEA; quality function deployment; QFD; zero one goal programming; ZOGP. DOI: 10.1504/IJHFE.2021.10036737
Integration of time information and temporal conformance graphics in map displays for navigation with space-time obligation by Chang-Geun Oh, Jennie J. Gallimore, Pamela Tsang Abstract: Design strategies on the display for navigation with multiple time obligations are developed and tested using a public bus application. The map display has a current time indicator and scheduled/estimated arrival time data at multiple bus stops. Two different time formats were applied to the time data at the bus stops: exact time at each stop and duration until them. Graphics symbols indicating earliness or lateness to ordinary scheduled time were also developed and tested. Under the four manipulated map types, experimenters asked participants eight different types of questions about space and/or time status. The experimenters then evaluated the response time and accuracy of produced answers. The response times were shorter or similar when the time formats corresponded questions. The workload rating and participants feedback showed an advantage of duration format and the temporal
conformance graphics. Keywords: navigation; space-time obligation; map display; temporal conformance; situation awareness; proximity compatibility; exact time vs. duration; text vs. graphics. DOI: 10.1504/IJHFE.2021.10037554
Shared mental models for cooperative fault diagnosis: effects on communication and diagnostic performance by Rica Bönsel, Romy Müller Abstract: To diagnose faults in a process plant, teams of physically separated operators must work together. They have access to differing information sources and need to rely on verbal communication, which can lead to various problems. Shared mental models facilitate team interaction, but most previous research collected information about mental models post-hoc. The present study manipulated the similarity of mental models by varying the amount of knowledge that participants received in an instruction phase. Three groups of ten dyads jointly diagnosed five faults in a simulated process plant, while either sharing a task model, a team model, or both. Teams that shared both models communicated less and used communication categories that differed from teams who only shared one model. Performance did not differ between groups, except for fewer rule violations when sharing both models. The findings suggest it may be beneficial to train all team members on the complete team
task. Keywords: shared mental models; task model; team model; cooperative fault diagnosis; team communication; process industries. DOI: 10.1504/IJHFE.2021.10038369
Effects of standing exercise tasks with a sloped surface intervention on trunk muscle activation and low-back pain intensity in women aged >70 years by Muhammad Tufail, Haebin Lee, YangGyu Moon, Hwang Kim, KwanMyung Kim Abstract: This study investigates the effects of standing exercise tasks with an incline-slope surface on the activation of latissimus dorsi (LD) and lumbar erector spinae (LES) muscles, and low-back pain (LBP) intensity. Sixteen LBP symptomatic subjects were equally and randomly divided into two groups, such as experimental and control groups based on standing interventions. The experimental group performed the exercise tasks with an incline-slope surface and the control group completed these tasks on a level surface. Electromyography and subjective LBP data were collected for five weeks to understand the intervention effects on the muscles and LBP intensity. The intervention significantly influenced trunk muscle activations and LBP intensity. The intensity of LBP was lowered in the experimental group as
compared to the control group. Changes in trunk muscle activations suggested that standing exercises with an incline-slope surface intervention can positively influence the activation of trunk muscles and potentially reduce LBP intensity. Keywords: trunk muscle activation; incline-slope surface; low-back pain intensity. DOI: 10.1504/IJHFE.2021.10038652
