ABSTRACT:
To operate the wheel chair of a paralyzed patient using
their eyeball movement using embedded system.
It is very difficult to understand the emotions of the
paralyzed patients, care them and to move them according to their wish. To
solve this problem this system is implemented.
The system consists of the eyeball sensor, which detects
the movement of the eyeball of the paralyzed patient and sends the information
to the microcontroller.the microcontroller processes the signals coming from
the eyeball sensor and controls the wheel accordingly. The moments of the
wheelchair that can be controlled by the microcontroller are forward, right and
left.
When the eye moves to the left side the wheelchair moves
to the left side. When the eye moves to the right side the wheelchair moves to
the right
side . When the eye looks straight wheelchair moves in forward direction.
To control the action of the wheel chair motors are used. The motors are drive
by the motor drivers.
The motors are coupled with the wheels and the wheels are
attached to the wheelchair mechanism.
