Magitek The Lautzenhiser Drive Control is a small, proportional sensor that can be worn on the top of the head (i.e. on a headband) or placed elsewhere on the body. By moving the sensor out of it's neutral zone, the wheelchair moves. The distance and direction the sensor is moved out of it's neutral zone determines the direction and speed of the wheelchair. This system is designed for a client with good head control. Pros: full directional and proportional speed control. The sensor can be calibrated for an individual, allowing the client to utilize available range of motion, even if this range is asymmetrical. No reset switch is required for reverse. Cons: The client must be able to quickly and accurately return to the neutral zone to stop the power wheelchair. This neutral zone can be adjusted, but may still be difficult for some clients to find, especially as there is no physical template. This access method is rather abstract, which can be challenging for clients with cognitive limitations. Reverse is controlled by tilting the head back, which can elicit tonal changes or reflexes in some clients. The system automatically recalibrates each time the wheelchair is turned on. This can be a pro or a con. If the client happens to be looking down when the system is turned on, the control is calibrated with the head in a downward position. This system is not appropriate for a client who needs the support of a headrest.
