Traditional stress monitoring lacks this nuance and struggles across varying flight tasks. This study proposes a multimodal neuro-cardiac framework combining functional near-infrared spectroscopy (fNIRS) and electrocardiography (ECG) to differentiate eustress and distress across tasks. Physiological data were collected from 35 participants under simulated flight missions inducing both stress types. Eleven features showing significant differentiation were identified and used to train classification models with machine learning algorithms. The model achieved 83.04% accuracy across tasks, and up to 90.83% within single tasks. These findings demonstrate the robustness of fNIRS-ECG-based monitoring in pilot stress classification. The proposed method offers objective biomarkers critical for adaptive intelligent cockpit systems, contributing directly to flight safety and human-machine interaction optimisation.</p>","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"1-23"},"PeriodicalIF":2.4,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144976584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present evidence highlighting how health inequalities can impact digital skills, affecting the use of DHI and potentially exacerbating existing health disparities.
