“Braking bad”:The influence of haptic feedback and tram driver experience on emergency braking performance

Trams are experiencing a resurgence with worldwide network expansion driven by the need for sustainable and efficient cities. Trams often operate in shared or mixed-traffic environments, which raise safety concerns, particularly in hazardous situations. This paper adopts an international, mixed-methods approach, conducted through two interconnected studies in Melbourne (Australia) and Birmingham (UK). The first study involved qualitative interviews, while the second was an experimental study involving a virtual reality (VR) simulator and haptic master controller (i.e., speed lever). In tram operations, master controllers play a critical role in ensuring a smooth ride, which directly influences passenger safety and comfort. The objective was to understand how a master control system, enhanced with additional haptic feedback, could improve tram driver braking performance and perceptions in safety-critical scenarios. Interview results indicate that the use of the emergency brake is considered the final or ultimate choice by drivers, and their driving experience is a moderating factor in limiting its application. Combined with the experimental results, this paper highlights how implementing haptic feedback within a master controller can reduce the performance disparity between novice and experienced tram drivers.</p

Adaptive Automation and the Third Pilot

Currently, automation does not take into consideration the cognitive and emotional state of the crew. Rather, automation provides assistance based on explicit and static task assignments, with no adaptive capabilities, even though it is capable of providing higher or lower levels of support depending on the crew state and/or complexity of the operational situation. This chapter presents a new adaptive automation concept which offers an innovative ‘team’ centred approach to solving crew awareness/workload management problems and enhancing flight safety. Partnership underpins the ‘Third Pilot’ approach. The crew (pilot flying and pilot monitoring), automation and the ‘Third Pilot’ are in charge together. Overall, partnership is proposed. This replaces existing paradigms involving dynamic changes in control function, where changes can be autonomously controlled by the system. Moreover, a new multimodal cockpit concept is advanced providing enhanced assessment of crew state/workload

Development of an observational protocol for reducing and mitigating workload and the risk of Retained Foreign Objects

Retained Foreign Objects are an uncommon but costly problem in today's healthcare. It regards the outcome after an unintended item is left behind in a patient after an invasive procedure. This paper presents the development of an observational protocol used for surgical observations in the FOR_RaM Project. The FOR_RaM or Foreign Object Retention - Reduction and Mitigation project aims to analyze and understand the problem of retained foreign objects in surgery and maternity settings in Ireland, develop hospital specific foreign object management processes and implementation roadmaps, with a focus on reducing and mitigating the risk of foreign object retention. This paper discusses the methodology used for developing an observational protocol as part of a socio-technical multi-methods approach in order to gain a better understanding of the existing practices that take place in these settings, including workload, operational processes and collaboration. Emphasis is placed on the observational template development and design, observational tasks, critical points, procedures and protocols followed throughout. This observation protocol has facilitated the collection of critical data and been successful in identifying good practices and potential areas for improvement

A-PiMod: a new approach to solving human factors problems with automation

To present a new adaptive automation concept which (1) addresses the still open human factors problems with automation from a new perspective and (2), as part of this, offers a new ‘cockpit/task’ centred approach to solving these problems

Stakeholder requirements for an ethical framework to sustain multiple research projects in an emerging living lab involving older adults

© The Author(s) 2019. Living Lab (LL) research should follow clear ethical guidelines and principles. While these exist in specific disciplinary contexts, there is a lack of tailored and specific ethical guidelines for the design, development, and implementation of LL projects. As well as the complexity of these dynamic and multi-faceted contexts, the engagement of older adults, and adults with reducing cognitive and physical capacity in LL research, poses additional ethical challenges. Semi-structured interviews were undertaken with 26 participants to understand multistakeholder experiences related to user engagement and related ethical issues in emerging LL research. The participants’ experiences and concerns are reported and translated into an ethical framework to guide future LL research initiatives

Developing a Feedback System to Augment Monitoring Performance of Aircraft Pilots

As a supervisor of a highly automated technical system, a human operator is the “ultima ratio” in abnormal situations that cannot be handled by the automation. Therefore, a human operator must adequately monitor the automated system throughout the entire operation. Unfortunately, humans tend to fall prey to a couple of demons leading to inadequate monitoring behavior, such as boredom, attentional tunneling or perservation. As a consequence, the human might lose situation awareness and be unable to detect and handle an abnormal situation in the given amount time. In this paper, we present a feedback system to augment monitoring performance on the part of an aircraft pilot. The feedback system has been developed under the umbrella of the European research and development project A-PiMod, where novel team-centered concepts for pilot-automation interaction are investigated

Exploring participation needs and motivational requirements when engaging older adults in an emerging living lab

There is a growing body of literature regarding living labs, which are seen as an effective way to develop and evaluate research for novel products and services with the actual end users. With growth in the living labs model, there is an increasing need for guidelines to steer and support the set-up and maintenance of initiatives, and to facilitate relationships and engage-ment with stakeholders and users in this context. This study seeks to address this need, in part, by exploring the needs, expectations, and motivations that older adults have in relation to research participation in an emerging living lab. This work is part of a wider research pro-ject to develop an integrated framework to guide emerging living labs. Eight semi-structured interviews were undertaken with six residents and two family members from two residential settings for older adults that were collaborating to establish a living lab environment. A concept-driven coding frame supported the coding and analysis of the interview transcripts. The results provide insights in relation to participant motivation to take part in research, and they identify some issues of concern for participants, both residents and family mem-bers, related to living lab initiatives. As a first step in developing a successful living lab cul-ture of collaborative research, this study has demonstrated that open discussion with residents and their families should continue to guide processes and research design as the emerging living lab initiative continues
