Functional near-infrared spectroscopy (fNIRS) in cognitive monitoring

Important results from the project

The project sought to rigorously test the viability of the Mendi headset (a wearable neuroimaging headband) as a cognitive monitoring device. This goal was achieved by running experiments using classical tasks of sustained attention while simultaneously recording Mendi data. The results of the experiments showed that Mendi is able to closely track brain activity during sustained attention tests and these results are currently being prepared for publication.

Expected long term effects

The projects results provide promise for the future development an fNIRS-based attentional state index that reflects focus and engagement. The ability to monitor and detect periods of low task engagement or lapses in concentration could have important consequences for operational safety, particularly for occupations that require concentration for long periods.

Approach and implementation

Implementation involved designing, running, and analysing experiments that tested the utility of the Mendi headset in monitoring the cognitive state of human users. Despite some delays from the Swedish Ethical Review board in granting ethical approval, the project developed as intended and the plan was followed.
