Abstract: Brain-computer interfacing (BCI) is currently gaining popularity for its increasing importance in bio-medical and rehabilitative applications. This tutorial aims at offering an introduction to design and development issues of BCI systems for neuro-prosthetic applications. Special emphasis would be given to EEG (electroencephalography) and fNIRs (functional Near Infrared spectroscopy) based system design with a focus to pre-processing, feature extraction, feature selection, classification and control aspects of the design. Feature selection algorithms to be covered include Principal Component Analysis (PCA), Independent Component Analysis (ICA), Common Spatial Patterns (CSP) and evolutionary techniques. Pattern recognition techniques to be offered includes Naïve Bayes, support vector machines, feed-forward neural classifiers and recurrent neural topologies. Main attraction of this tutorial lies in the practical perspectives of system design for upper limb prosthesis and rehabilitation, cognitive load detection in human subjects during complex problem solving, detection of cognitive failures in driving, and movement control of artificial limbs for patients with brain injury during his/her participation in tennis games.
