Cortivision new publication on fNIRS+VR in Sensors

Publication on fNIRS + VR integration from Cortivision

In our recent publication (1), we present the results of an evaluation study of Cortivision Photon Cap Spotlight system (Figure 1.). We prove that it is possible to use a mobile fNIRS to detect and train attentional states in an attractive VR environment.

More precisely, we have shown that by using machine learning algorithms, it is possible to discriminate between the enhanced attention engagement (n-back task performance) and the relaxation state based on hemodynamic activity from the two different brain areas (dorsolateral prefrontal cortex- DLFPC and medial frontal gyrus – MFG). Moreover, we have checked a subjective experience of interaction with the system (fNIRS + VR) to find which elements affect various aspects of user satisfaction. Our study shows also that combining fNIRS and head-mounted-display technologies enables the effective transfer of experimental cognitive procedures to a controlled VR environment.

Last but not least, we proposed, a new  signal processing pipeline (Figure 2.) in open-source software OpenViBE to provide a universal framework for future fNIRS-BCI and neurofeedback studies.
