Horizontal and vertical electro-oculograms were measured using two surface electrodes attached above and beside the dominant eye and referring to an earlobe electrode and amplified with AC-coupling in order to reduce the unnecessary drift. Four directional cursor movements -up, down, right, and left- and one selected operation were realized by logically combining the two detected channel signals based on threshold settings specific to the individual. Letter input experiments were conducted on a virtual screen keyboard. The method's usability was enhanced by minimizing the number of electrodes and applying training to both the subject and the device. As a result, an accuracy of 90.1±3.6% and a processing speed of 7.7±1.9letters/min. were obtained using our method.}, pages = {1790--1797}, title = {Development of a Communication Support Device Controlled by Eye Movements and Voluntary Eye Blink(Vision and Image,Human Communication II)}, volume = {E89-D}, year = {2006} }
