Maysam Ghovanloo, a Georgia Tech assistant professor who leads the team's research said that punters could have full control over their environment by moving their tongue. Philosophically speaking, no change there then.
The tongue interface is being designed for disabled people and will allow them to manipulate wheelchairs, manage home appliances and control computers.
Currently the design has been labelled grotesque, but is coming along, apparently.
The tongue has the advantage as an interface because it is wired up to the brain rather than the spinal cord and works when other parts of the body don't.
