Wheelchairs can be a incredibly hard for some to navigate in, especially those who are completely paralyzed from the neck down (quadriplegics), but the Tongue Drive System hopes to make the mode of transportation that much easier. As its name suggests, it is a system that is controlled via the tongue, hence the mouth is how people will communicate to the wheelchair which way to go.
Developed by researchers from Georgia Tech, the Tongue Drive System has been worked on since 2005. It has only been recently, however, that it seems a viable alternative to other methods of control. Maysam Ghovanloo, the research's principal investigator, says in a statement, "It's really easy to understand what the Tongue Drive System can do and what it is good for. Now, we have solid proof that people with disabilities can potentially benefit from it."
