Query: A Critical Look at Smart Wheelchairs   Research into smart wheelchairs has been conducted for decades, but we have
yet to see the widespread use of this technology among full-time wheelchair
users. We argue that the main reason for this is that there is a mismatch
between research and the actualities of using a powered mobility device in the
real world. Based on our own research experiences, we enumerate some of these
disparities, and offer some suggestions for where work in smart wheelchairs
might focus in the coming years.
