3 Dead zone
This area sets the range in which the wheelchair does not react to joystick input. The area
appears in black on the graph display on the Joystick Path Setting Window. The wheelchair
does not move when the tilt of the joystick is inside the dead zone range.
Set a wide dead zone range when the user's hand slightly shakes in order to prevent unintended
movement. Set a narrow dead zone when the user cannot move the joystick well in order to
make the wheelchair move in response to a smaller operation.

4 Input switching direction (Forward/Backward, Left/Right)
This area sets the input direction of the joystick to forward or backward, to the left or right.
When set to [Standard], the direction in which the joystick is tilted matches the movement of
the wheelchair.
When set to [Reverse], the direction in which the joystick is tilted is opposite to the movement
of the wheelchair. When a chin controller or anything similar is used, change the setting as
required.
Be sure to explain any changes made so that the user understands the characteristic
movement of the wheelchair. Verify that the user can operate the wheelchair safely.
