An electrooculogram based assistive communication system with improved speed and accuracy using multi-directional eye movements

Human-Computer Interface (HCI) enables people to control computer applications using bio-electric signals recorded from the body. HCI can be a potential tool for people with severe motor disabilities to communicate to external world through bio-electric signals. In an Electrooculogram (EOG) based HC...
