Human computer interaction (HCI) is an interdisciplinary field that involves the study and development of user interfaces for computers. One challenge of HCI is the collection of quantitative information on human computer users, which is fundamental for evaluation purposes and real-time input. The collection of neurophysiological data of cognitive workload has been proposed using multivariate elec... read moretroencephalography (EEG) and also functional near infrared spectroscopy (fNIRS) In this work we propose to use machine learning algorithms for the analysis of near-infrared data, and apply this approach to process data collected on the forehead of human subjects while they perform tasks of increasing cognitive workload levels. The purpose is to develop a tool for quantitative and real-time assessment of cognitive workload to provide continuous feedback to a dynamic human-computer interface.read less
