The Eye Directive wheelchair is a mobility aid for people with moderate or severe physical disabilities or chronic diseases, as well as for the elderly. There are several wheelchair interfaces available in the market, they are still underutilized, the reason being the ability, the power and the presence of the mind necessary to operate them. The proposed model is a possible alternative. In this model, we use the optical eye tracking system to control the motorized wheelchair. The movements of the user's eyes are translated to the position of the screen using the optical tracking system, without direct contact.
When the user looks at the appropriate angle, then the computer input system will send the command to the software based on the angle of rotation of the pupil, ie when the user moves his eyes left (move left), right (Move to the right) In all other cases the wheelchair will stop.
In addition, obstacle detection sensors are connected to the Arduino to provide the feedback necessary for the correct operation of the wheelchair and to ensure user safety. The motors connected to the wheelchair support the differential steering that prevents clumsy movement. The wheelchair is also equipped with a joystick control to ensure a safe movement in case of sight fatigue and with a safety stop button, which will allow the user to stop the wheelchair in its own facility.
A wheelchair is a wheelchair, invented early in the fifth century. The device comes in variations where it is propelled by the engines or by the occupant sitting turning the rear wheels by hand. Often there are handles behind the seat for someone else to push. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury or disability. People who have difficulty sitting and walking often need to use a wheelchair. A basic manual wheelchair incorporates a seat, footrest and four wheels: two, wheels on the front and two large wheels on the back. Other varieties of wheelchair are often variations on this basic design, but can be highly customized for the needs of the user. Such customizations may include seat dimensions, height, seat angle (also called seat discharge or discharge), footrests, footrests, front wheel stabilizers, adjustable backrests and controls. An electric wheelchair is a wheelchair that moves through the means of an electric motor and navigation controls, usually a small joystick mounted on the armrest, rather than manual feeding. For users who can not handle a manual joystick, head switches, chin-driven joysticks, sip-and-puff or other specialized controls can allow stand-alone operation of the wheelchair.
