Scientists say device could alert workers such as pilots and healthcare staff when they are feeling the strain
“For this kind of high-demand and high-stake scenario, eventually we hope to have this real-time mental workload decoder that can give people some warning and alert so that they can self-adjust, or they can ask AI or a co-worker to offload some of their work,” said Dr Nanshu Lu, an author of the research from the University of Texas at Austin, adding the device may not only help workers avoid serious mistakes but also protect their health. Writing in the journal Device, Lu and colleagues describe how using questionnaires to investigate mental workload is problematic, not least as people are poor at objectively judging cognitive effort and they are usually conducted after a task. After finding the e-tattoo worked as well as traditional EEG and EOG devices for monitoring brain waves and eye movements the team tested the technology on six participants.
