人因学发展的新取向

当前新技术、人机交互的新特征、社会和人的新需求给中国人因学(Human Factors)的进一步发展创造了一个有利时机。本文首先讨论和分析了一些具有代表性的开拓了人因学科研究深度和广度的新技术和新途径, 包括神经人因学, 认知工程, 协同认知系统, 社会技术系统; 以及人因学科应用中的一些挑战和策略。然后, 就进一步发展我国的人因学科, 本文提出首先要解决的问题是建立多学科交叉的人因学科的科研教育体制, 并在此基础上, 注重理论创新, 以创新设计为突破点, 在智能系统、用户体验、航天航空和医疗健康等领域中优先发展和应用。当前迫切需要解决的是, 建立完善的人因学科高校教育体系, 建立完善的人因学科多学科交叉的科研体系, 以及建立人因学科行业资质标准和设计标准体系。     

Using real-time visual feedback to improve posture at computer workstations

The purpose of the current study was to examine the effects of a multicomponent intervention that included discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer workstation in a simulated office environment. Using a nonconcurrent multiple baseline design across 8 participants, the study assessed the effects of the intervention across three postural variables. Following an information phase, the intervention started for the lowest stable postural variable. The intervention led to substantial improvements in safety behavior for most targeted postural variables. A reversal to the information phase for 2 participants did not lead to decreases in safety. Postures self-monitored with high accuracy improved to a greater degree than postures self-monitored with low accuracy.     

军事应激下的认知工效学研究

回顾了近20年来军事应激下的有关认知工效学研究,主要包括五部分：基本理论;应激对认知的影响;研究方法;处理应激的方法;总结。其中在研究方法中重点是对已有事故的分析,竞争性游戏和虚拟现实技术。在减少应激对认知不良影响的方法中值得注意的是：对抗应激人员的选拔、对人员的训练和能够对抗应激的人－机系统的开发。对于我军今后类似研究提供了思路和可能入手点     

学习论视角下的教育工效学理论模型的发展与应用

教育工效学是工效学研究中长期被忽视的重要研究领域,其发展以各教育工效学模型的提出为主线。本文从模型设计、模型应用和学习论视角出发,分析了Kao模型,Smith模型和六角轴模型的理论基础,发现现有的这三个模型在设计上多从工效学角度出发,与学习论的结合不够紧密。为了给信息化教学系统设计提供更有价值的理论模型和更可行的设计方法,有必要从工效学原理与教学理论的深度衔接入手,并基于学习论的视角给模型应用和完善提供一些可行的建议。

Treadmill based reference running data for healthy subjects is dependent on speed and morphological parameters

ObjectiveTo obtain spatiotemporal and dynamic running parameters of healthy participants and to identify relationships between running parameters, speed, and physical characteristics.MethodA dynamometric treadmill was used to collect running data among 417 asymptomatic subjects during speeds ranging from 10 to 24 km/h. Spatiotemporal and dynamic running parameters were calculated and measured.ResultsResults of the analyses showed that assessing running parameters is dependent on running speed. Body height correlated with stride length (r = 0.5), cadence (r = −0.5) and plantar forefoot force (r = 0.6). Body mass also had a strong relationship to plantar forefoot forces at 14 and 24 km/h and plantar midfoot forces at 14 and 24 km/h.ConclusionThis reference data base can be used in the kinematic and kinetic evaluation of running under a wide range of speeds.     

Sustainable system-of-systems and francophone activity-centered approaches in ergonomics: Converging and diverging lines of dialogue

This paper initiates a dialogue between the sustainable system-of-systems (SSoS) approach and one particular situated approach of activity analysis within francophone activity-centered ergonomics (FACE). This paper explores the possible cross-fertilizations between FACE and SSoS in coping with the challenge of enlargement which ergonomists have to face in order to address sustainability issues. We present how the SSoS model and FACE have currently considered the challenges of sustainable development and the theoretical-methodological principles that frame their approaches. Then, eight topics of dialogue are introduced and debated in order to open the dialogue between the two approaches where emerging lines of convergence are generated. We conclude by further discussing the complementarity between FACE and SSoS in the objectives of their approaches and the levels analysed by each approach, and by highlighting the importance of taking into account the emergent and complex aspects of systems. One possible way forward might be to “situate the sustainable system-of-systems” while also “systemizing systems of sustainable situations” for the future.     

Generalization of posture training to computer workstations in an applied setting

Improving employees' posture may decrease the risk of musculoskeletal disorders. The current paper is a systematic replication and extension of Sigurdsson and Austin (2008), who found that an intervention consisting of information, real-time feedback, and self-monitoring improved participant posture at mock workstations. In the current study, participants worked in an applied setting, and posture data were collected at participants' own workstations and a mock workstation. Intervention in the mock setting was associated with consistent improvement in safe posture at the mock workstation, but generalization to the actual workstation was limited.
