Injecting 3D worlds directly into the brain

Experiments are being done to allow blind people to see objects by directly simulating their brain. This is a new way to sense the world or to sense a 3D virtual world. Could variations of this technology be used to overlay information from a virtual world with a sighted person’s perception of the real world? This would be a more intense/intrusive method of achieving augmented reality. So a soldier at National Training Center would be able to see the 3D image of an opponent that exists only in a simulation – a new step in Live/Virtual interoperability. Of course the question is who would allow this to be done to them and would it be any better than augmented reality using half-reflective glasses?
