However, since most of these manual wheelchairs are focused on movement only, the disabled or the elderly with serious disabilities in the arm or other body are almost unavailable without the help of others.

Recently, there has been developed many electric wheelchairs that can be easily used by using an operation lever such as a joystick without a direct force of the user by driving the wheel by the motor installed in the body of the car.

As described above, since the handicapped person or the elderly who mainly use electric wheelchairs are accustomed to the operation of the joystick, there is a tendency to use the joystick to control the peripheral device.

However, in order to control a peripheral device with a joystick of an electric wheelchair, it is necessary to implement an interface for connecting a joystick and a peripheral device, so it is inevitable to modify the electric signal system or to modify an electric wheelchair. As a result, The problem could have occurred.

In addition, when the joystick is operated in a state where the electric wheelchair is inclined in the inclined position, it is difficult to accurately recognize the movement of the joystick due to inclination.
