Researchers develop methods to measure how AI assistance affects mental workload during real work tasks

Study focuses on quantifying cognitive load in practical AI-assisted work environments rather than lab settings

Research proposes 'precision proactivity' approach to understand when AI help reduces versus increases mental burden

Findings could help design AI tools that genuinely lighten cognitive load for workers across different task types
