摘要

在振动环境下的人机交互(HCI)任务中,越来越多地引入了半空中交互,但很少从人体工程学方面对其进行评估,尤其是与设备辅助交互相比。本研究旨在根据任务表现、上肢和肩部肌肉活动以及用户感知,对振动环境下的空中交互和设备辅助交互进行全面的人体工程学评估。本研究采用了被试内设计,要求被试在静态、低振动和高振动环境下分别完成四种交互模式(即一种半空交互和三种设备辅助交互)的基本指向和拖动任务。测试的目标尺寸有大有小。用表面肌电图记录了参与者主导手臂上五块肌肉的活动。结果表明,与设备辅助交互相比,中空交互的任务完成时间更长,错误更多,感知工作量更大,可用性评分更低,前臂、上臂和肩部的肌肉活动更大。振动和交互模式之间存在明显的交互效应。具体来说,与设备辅助交互相比,中空交互更容易受到振动的不利影响(任务表现较差,肌肉活动较大)。目标大小对任务表现有明显影响,但影响因任务而异。总之,我们的研究结果表明,与设备辅助交互相比,中空交互具有更高的人体工程学风险,尤其是在振动环境中。这些研究结果为更好地使用、配置振动环境中的交互工具并对其进行人体工程学评估提供了启示,同时也有助于制定循证干预措施,以控制振动环境中人机交互任务的人体工程学风险。

Ergonomic assessment of mid-air interaction and device-assisted interactions under vibration environments based on task performance, muscle activity and user perceptions

Mid-air interaction has been increasingly introduced for human-computer interaction (HCI) tasks in vibration environments, but it has seldom been assessed from ergonomic aspects, especially in comparison with device-assisted interactions. This study aimed to provide a comprehensive ergonomic assessment of mid-air interaction and device-assisted interactions under vibration environments based on task performance, muscle activity in the upper limb and shoulder, and user perceptions. A within-subjects design was implemented in this study, where participants were required to perform basic pointing and dragging tasks with four interaction modes (i.e., one mid-air interaction and three device-assisted interactions) under static, low and high vibration environments, respectively. Both small and large target sizes were examined. Muscle activity was recorded with surface electromyography for five muscles from participants’ dominant arm. Results showed that mid-air interaction yielded longer task completion time, more errors, higher perceived workload, lower usability ratings, and larger muscle activities in the forearm, upper arm and shoulder compared with device-assisted interactions. There were significant interaction effects between vibration and interaction mode. Specifically, compared with device-assisted interactions, mid-air interaction was associated with greater susceptibility to the detrimental effects of vibration (poorer task performance and larger muscle activities). Target size significantly affected task performance, but the effects varied by tasks. Overall, our results suggest that mid-air interaction presents a higher ergonomic risk compared with device-assisted interactions, especially in vibration environments. These findings provide implications for better use, configuration and ergonomic assessment of interaction tools in vibration environments, and are useful in developing evidence-based interventions to control ergonomic risk in HCI tasks in vibration environments.

期刊介绍: The International Journal of Human-Computer Studies publishes original research over the whole spectrum of work relevant to the theory and practice of innovative interactive systems. The journal is inherently interdisciplinary, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization, which is relevant to the design, analysis, evaluation and application of innovative interactive systems. Papers at the boundaries of these disciplines are especially welcome, as it is our view that interdisciplinary approaches are needed for producing theoretical insights in this complex area and for effective deployment of innovative technologies in concrete user communities. Research areas relevant to the journal include, but are not limited to: • Innovative interaction techniques • Multimodal interaction • Speech interaction • Graphic interaction • Natural language interaction • Interaction in mobile and embedded systems • Interface design and evaluation methodologies • Design and evaluation of innovative interactive systems • User interface prototyping and management systems • Ubiquitous computing • Wearable computers • Pervasive computing • Affective computing • Empirical studies of user behaviour • Empirical studies of programming and software engineering • Computer supported cooperative work • Computer mediated communication • Virtual reality • Mixed and augmented Reality • Intelligent user interfaces • Presence ...
