Eyeboard Electrooculography (EOG) System

Note: Be sure to check out the Kickstarter campaign of the Eyeboard project. This is an inexpensive yet reliable human-computer interface that detects eye movements using electrooculography (EOG), a biomedical technique based on picking up signals from electrodes placed around the eyes. EOG interfaces let users who can’t manipulate a... Read more »
