摘要

This study assessed the efficacy of an extended reality device to augment human performance during a dual-task paradigm. Dual-tasking is critical for successful high-risk military operations. However, current practices to improve mission success involving dual-task elements often require additional personnel which can increase risk and strain resources. Therefore, head-mounted extended reality devices which augment an individual's sensory and cognitive capacities could circumvent these issues whilst enhancing/maintaining task success. Utilising a repeated measures, counterbalanced, randomised design, 18 participants (8 females) simultaneously completed a primary ball-searching task and a secondary semantic verbal fluency task. Participants completed three conditions: using extended reality human augmentation; receiving memory prompts; or no support, each comprising three trials. Participants reported their perceived effort (post-trial), environmental presence (post-condition), and system usefulness/usability/sickness (post human augmentation condition only). Friedman’s tests identified that participants retrieved significantly more correct balls, significantly faster during the human augmentation versus memory prompt or no support conditions. Semantic verbal fluency and aggregated performance were also significantly better within the human augmentation condition than the no support condition. Perceived effort was lowest within the human augmentation condition. Within-condition, trial-by-trial differences emerged for semantic verbal fluency and aggregated performance within the human augmentation condition only. An extended reality, human augmentation device elicited significantly better dual-task performance compared to conditions reflecting current best practice (memory prompts) or no support which could be attributed to an alleviation of cognitive load. Within-condition effects suggest that even short-term exposure to extended reality devices can lead to immediate dual-task performance improvements.
