Abstract—This paper describes an eye-control method based
on electrooculography (EOG) to develop a system for assisted
mobility. One of its most important features is its modularity,
making it adaptable to the particular needs of each user according
to the type and degree of handicap involved. An eye model based
on electrooculographic signal is proposed and its validity is
studied. Several human-machine interfaces (HMI) based on EOG
are commented, focusing our study on guiding and controlling
a wheelchair for disabled people, where the control is actually
effected by eye movements within the socket. Different techniques
and guidance strategies are then shown with comments on the
advantages and disadvantages of each one. The system consists
of a standard electric wheelchair with an on-board computer,
sensors and a graphic user interface run by the computer. On
the other hand, this eye-control method can be applied to handle
graphical interfaces, where the eye is used as a mouse computer.
Results obtained show that this control technique could be useful
in multiple applications, such as mobility and communication aid
for handicapped persons.
