The main objective is the development of novel metrics derived from the analysis of functional Near Infrared Spectroscopy (NIRS) signals to access core cognitive processes in mixed reality. The goal of the ESR will be to develop a fully functional suite of software algorithms for an application of fNIRS as a neuro-business tool. In more detail, the work will consist of: 1) Extraction of artefacts and systemic factors of the NIRS signal using hemodynamic models, and non-parametric spectral estimation techniques such as Singular Spectrum Analysis and Empirical Mode Decomposition; 2) Evaluating psychological methods and tests to determine participant’s mental state and decision process; 3) Applying Machine Learning techniques such as Recurrent and Convolutional Neural Networks on multimodal ANS and NIRS features to infer the participant’s mental state and decision process; 4) Embedding above developed algorithms in a fNIRS software suite to be used in conjunction with an Artinis fNIRS neuro-business device.
