As most of us do not use wheelchairs, we do not often stop to think of the improvements that could be made on them--we figure they are fine enough already. What we don't know is that many models are not ergonomically correct and can cause pain for the user. The Hubless Wheelchair Concept is designed so as to provide as much comfort to the driver as possible.
The Hubless Wheelchair Concept was designed by Thomas Ross and Dave Cochrane and has two very cool features. For one, it has a gyroscope-type ball on the back, acting as sort of a third wheel so as to reduce strain on the user's legs when turning. The other very nifty feature is the voice command system through an iPod that lets the user go totally hands-free.
