Objective
Develop algorithms for both quantitative EEG and gaze detection, and to integrate them in systems to assist people with disabilities in communication and control.
Description
Different signal processing techniques (Higher Order Statistics, Principal Component Analysis, Independent Component Analysis, Time Varying Auto Regressive Models) are being used in the lab to extract features from EEG signals, and thus to allow control of PC through Brain Electrical Activity.
The same approach is being followed by video-recording and then analysing gaze when doing activities on PC, with the aim of assisting impaired people.
