Abstract

This study investigated the effects of non-driving related tasks (NDRTs) and seat back angles (SBAs) on preferred seat parameters and seating discomfort in highly automated vehicles. Using a static, reconfigurable experimental seat, 32 participants self-selected preferred seat parameters for four tasks with varying vision demands (relaxing, looking forward, working on a laptop, watching a tablet video) at three SBAs: 20°, 40° and 60°. Results show that SBA influenced all self-selected seat parameters, while task only affected those related to the headrest. Fore-aft headrest adjustability is necessary to support different NDRTs, particularly in reclined postures. Upright and moderately reclined positions were preferred for downward-looking tasks like laptop or tablet use, while more reclined positions were better suited for relaxing without visual demand. The findings also highlight the importance of suitable support for tablet use to reduce discomfort. They could be useful for seat and vehicle interior design in future automated vehicles.

非驾驶相关任务和椅背角度对高度自动驾驶汽车优选座椅参数的影响

本研究探讨了非驾驶相关任务（NDRTs）和座椅靠背角度（SBAs）对高度自动化车辆偏好座椅参数和座椅不适的影响。使用一个静态的、可重构的实验座椅，32名参与者在三个SBAs: 20°、40°和60°，自行选择四种不同视觉需求的任务（放松、向前看、在笔记本电脑上工作、观看平板电脑视频）的首选座椅参数。结果表明，SBA对所有自选座椅参数都有影响，而任务只影响与头枕相关的参数。前后头枕的调节是必要的，以支持不同的NDRTs，特别是在倾斜的姿势。在使用笔记本电脑或平板电脑等向下看的任务时，人们更喜欢直立和适度倾斜的姿势，而更倾斜的姿势更适合在没有视觉需求的情况下放松。研究结果还强调了使用平板电脑时适当的支持对于减少不适的重要性。它们可以用于未来自动驾驶汽车的座椅和内饰设计。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
