Physiological indicators of task demand, fatigue, and cognition in future digital manufacturing environments

Abstract As Digital Manufacturing transforms traditionally physical work into more system-monitoring tasks, new methods are required for understanding people’s mental workload and prolonged capacity focused attention. Many physiological measures have shown promise detecting changes in cognitive state, recent advances sensor technology offer minimally-invasive ways to monitor our activity. Previous research functional near-infrared spectroscopy, example, has observed cerebral hemodynamic response during periods of high demand within tasks. This investigated the relationships among task demand, fatigue, attention degradation a sustained task, their effect on heart rate, breathing nose temperature prefrontal cortex middle temporal gyrus. Analysis revealed small but significant fatigue rate relative baseline, response. Task had temperature, both no difference between levels was or Our results provide insight what data can tell us about ability focus, impact over time.
