*2.8. Modified Ride-On Cars*

Ride-on cars will be modified with a joystick for activation. Joystick control will allow omni-directional turning and proportional speed-control. The vast majority of research with modified ride-on cars has installed a large, easy-to-press, all-or-nothing activation switch that does not provide turning nor speed control. These steering and speed modifications will enhance the ability for young children with CZS to explore the environment and use the device within the home and community. Joystick activation ensures that children are provided with an opportunity to use an activation method that is consistent with future joystick-driven device options, such as motorized wheelchairs. Ride-on cars will be modified with optimal seating support using readily available, low-cost materials based on each child's individual needs. Ride-on car models will be selected based on their design and structure to provide seating support.
