AR also made these tasks feel easier for those with less experience. For ergonomics and human factors practitioners, these results suggest that AR can be a valuable tool for improving onboarding and performance in environments where workers are new or frequently face varied tasks. Implementing AR guidance can help reduce learning curves and support more efficient work, particularly in settings with high complexity and employee turnover. However, if workers are expected to perform tasks independently without ongoing AR support, traditional, more thorough training methods may still be necessary. Practitioners should consider the nature of the work and the use of AR technology when designing onboarding and training programs to maximize both efficiency and long-term competence.</p>","PeriodicalId":73332,"journal":{"name":"IISE transactions on occupational ergonomics and human factors","volume":" ","pages":"1-18"},"PeriodicalIF":1.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-stage machine learning framework, which first determines anger presence and then classifies its intensity, substantially improved accuracy and reduced neutral state misclassification compared to a single-stage four-class model. These findings have direct implications for reducing safety risks and promoting long-term health for workers whose jobs involve extensive driving (e.g., commercial drivers, bus operators), who encounter anger-eliciting situations more frequently than non-occupational drivers. Integrating anger-intensity detection into driver monitoring systems can enable adaptive, context-aware assistance systems that consider both intervention timing and emotional intensity. Aggregated emotion-intensity information may also inform operational decisions (e.g., dispatch assignments and break scheduling) by identifying periods when drivers may benefit from reduced demands or modified tasks. These implications can enhance fleet safety programs and support worker well-being by reducing exposure to emotionally demanding conditions.</p>","PeriodicalId":73332,"journal":{"name":"IISE transactions on occupational ergonomics and human factors","volume":" ","pages":"1-14"},"PeriodicalIF":1.8,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
