The left right movement of the joystick can be used to steer the wheelchair by differentially driving the wheels. The Y-axis of the joystick, or say the forward and back motion of the joystick can be used to vary speed and direction - pulling the joystick back from the centre-point could make the motors reverse direction. But in all this, do remember to keep a deadband around the centre-point of the joystick, wherein the values do not do anything. Otherwise you might land up with a wheelchair that keeps creeping even without any control input...
