Contemporary work environments require humans to process audiovisual information displays during active locomotion. The attentional demands associated with using devices such as in-ear headphones and head-mounted displays may be significantly influenced by varying locomotor demands, yet this relationship remains poorly understood. This study investigates the interplay of information presentation modality, movement state, and cognitive task difficulty. In a virtual reality laboratory, 22 participants performed a cued task-switch paradigm with three cognitive task difficulty levels while standing, walking, or walking with perturbations on a treadmill. We used a questionnaire, behavioral, and mobile EEG data to investigate cognitive-motor interference. We find that locomotion interfered with cognitive task performance, and that the presentation modality of task-switch notification modified the nature of this interference. While auditory cue presentation resulted in faster responses under low cognitive load conditions, visual information presentation was less impaired by higher cognitive and locomotor demands. A detailed analysis of the EEG response to cues addressed these differences in terms of multi-modal attentional mechanisms. Hence, information presentation on wearable devices should be tailored to the specific task demands, particularly for cognitively demanding information in mobile work settings.
当代工作环境要求人们在主动移动过程中处理视听信息显示。使用入耳式耳机和头戴式显示器等设备时的注意力需求可能会受到不同运动需求的显著影响，但这种关系仍未得到充分理解。本研究调查了信息呈现方式、运动状态和认知任务难度之间的相互作用。在虚拟现实实验室中，22名参与者在跑步机上站立、行走或行走时带有干扰的情况下，执行了具有三个认知任务难度级别的提示任务切换范式。我们使用问卷、行为和移动脑电图数据来研究认知-运动干扰。我们发现，运动干扰了认知任务表现，并且任务切换通知的呈现方式改变了这种干扰的性质。虽然在低认知负荷条件下，听觉提示呈现导致反应更快，但视觉信息呈现受较高认知和运动需求的损害较小。对脑电图对提示的反应进行的详细分析从多模态注意力机制方面解释了这些差异。因此，可穿戴设备上的信息呈现应根据特定任务需求进行定制，特别是对于移动工作环境中认知要求较高的信息。
