The EMC advanced driving Joystick is one of the devices that allow the wheelchair user to steer a vehicle when integrated with a primary control unit. The PRIMARY Control unit is the device that controls all the driver's input and is necessary to connect the various hardware elements used in controlling the vehicles Acceleration, Braking, and Steering Functions. The natural "plug and play" design of the EMC AEVIT 2.0® is what allows for the high level of customization needed to build a users system around their individual physical needs. If over time, physical needs should change, this device allows for easy swapping of input devices, minimizing vehicle downtime.

The EMC AVIT touch screen works to control vehicles secondary functions. SECONDARY vehicle controls are all of the other electro-mechanical features like lights, wipers, shifter, horn, A/C, etc. The integrated "compact flash" upgrade drive of AEVIT 2.0® allows for custom loading of secondary switch inputs. This set of functions can easily be upgraded and changed if necessary or due to any physical changes that necessitate the change. In most cases, merely inserting a compact flash upgrade is all that is necessary.
