![Page 3: Visual neuro ergonomics in naturalistic simulation](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a6d91587f8b9a16428b5c27/html5/thumbnails/3.jpg)
IEA definition:
Visual ergonomics is the multidisciplinary science concerned
with understanding human visual processes and the interactions
between humans and other elements of a system.
It applies theories, knowledge and methods to the design and
assessment of systems, optimizing human well-being and overall
system performance.

Visual neuro-ergonomics approaches and corresponding
neuroimaging devices (EEG, mainly) can provide direct knowledge
on brain activity on real time and apply neurofeedback to train or
reinforce cognitive performance (attention, decision taking, etc.).
Brain-machine-interface (BMI) applications can explore now and
propose new disruptive innovations for improving well-being of next
generations in many daily situations (work, leisure, health recovery).
