There are patients who have lost control of both arms and legs, as a result of higher-level spinal cord injury or brain and nervous system disorder. These kinds of patients can’t use the standard wheelchair which depends on the arms muscular force to move the wheelchair. At the same time, they can’t use the electrically powered wheelchair which is controlled by a joystick.
So these types of patients still want the help of another person to move their wheelchair from one place to another.
Many researchers have proposed different methods to control the wheelchair.
One of the possible solutions for them is to use their eyeball movement to control the wheelchair.
Mechanism of the Chair
The control of the wheelchair depends upon the eyeball sensor, which will do the functions like right, left, forward and reverse operations. The wheelchair is designed in such a way that it can move freely without external support or dependency.
Through this feature, the patients can enable movements of their wheelchair as per their desire.
The system is designed in such a way that it is simple, cost-effective and easy to operate so that it aids the physically challenged people. However, the efficiency of the system mostly depends on the controller program, as the human eye moves more to sudden changes in the system, rather than a normal change.
Hence the system should be designed in such a way fast to measure eyeball movement and more efficient to process.
Obstacle sensor is used to detect an object in the undesired condition such as dark areas, glass walls or stones, smoke area, etc.
