I have a little trouble with the fact that a helicopter pilot can aim a cannon
with his eye and yet its that damn difficult for so many people to get simple
to use control systems for power wheelchairs. It isn't the technology that is
infuriating, it is the mindlessness that goes into the application of that
technology.

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.
