As drivers continue driving despite being aware of their drowsy states, it is necessary to adopt active countermeasures to avoid them falling asleep behind the wheel. Based on the multiple resources model, this study proposed five countermeasure types using voice assistants (no-countermeasure vs. meaninglessly listening vs. meaningfully listening vs. repeating vs. answering) and investigated their effects on countering drowsiness for young and middle-aged drivers. A five-week simulated manual driving experiment was conducted to evaluate the effectiveness of countermeasures based on driver performance, physiological indicators, eye movement indicators, and subjective ratings. Results indicated that repeating and answering were the two most effective countermeasures. The self-reported sleepiness of these two countermeasures (6.328 and 5.276 for repeating and answering, respectively) were significantly (p < 0.05) lower than that of the no-countermeasure (7.983). The physiological arousal state in term of skin conductance level for the two (1.798 and 1.990 for repeating and answering, respectively) were significantly (p < 0.05) higher than that of the no-countermeasure (1.022). Consistent patterns were also found in driving performance, eye movement indicators, psychomotor vigilance task accuracy, and subjective acceptance ratings. These findings suggested that countermeasures involving more resource stages can enhance drivers' alertness. The trend of higher alertness in the answering condition compared to the repeating condition highlighted the advantage of increasing cognitive load in countering drowsiness. Although young and middle-aged drowsy drivers did not differ on their average responses to different countermeasures, they showed differences in their physiological activation in reacting to the countermeasures. Drowsiness countermeasures should be tailored to fulfill individual needs, particularly for middle-aged drivers. This study not only clarifies how drowsiness countermeasures work but also offers practical guidance for vehicle designers on using in-vehicle voice assistants effectively.</p>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"129 ","pages":"104616"},"PeriodicalIF":3.4,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144805286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-five participants completed a block layout assembly task in two cognitive task demand conditions: easy and hard. Cognitive workload was measured via ocular and self-reported metrics; performance in the assembly task was also measured. Relative to video and pictorial guidance, laser projection was associated with the lower cognitive workload and quicker task times in the easy cognitive task demand condition. However, no differences between the three operator guidance systems were found in the hard condition. Findings show the potential for laser projection operator guidance to improve assembly performance and reduce operator's workload in the absence of a secondary task.

We evaluated the benefits and potential unintended consequences of BSEs during construction work, considering worker experience levels. Forty participants (20 novices and 20 experienced, balanced in both groups by sex) completed lab-based simulations of several construction-relevant tasks. These tasks were performed under a control condition (no BSE) and with three BSEs, each of which was tested in two support settings (on and off). Task performance was measured using completion time, and perceptions of diverse aspects of usability were obtained. Generally, BSE use increased task completion time, perceived discomfort, and perceived interference of BSEs during simulated tasks, while its effects on perceived physical effort were mixed. Rigid BSEs particularly increased perceived movement restrictions, while a soft BSE (or exosuit) did not. In a few cases, the effects of BSEs on completion time and BSE usability differed between novice and experienced groups. While some differences were observed between experience levels, future work could focus on novice populations with caution regarding specific outcomes.
