If a three axis magnetometer was used in conjunction with electrical nerve stimulation on multiple sites, you could have the full range of compass heading, local magnetic field density and ac field sensing. Which would be cool. This has probably already been covered by the NASA Human Systems Integration Division, so it might be worth having a dig through some of their stuff - http://hsi.arc.nasa.gov/index.php http://hsi.arc.nasa.gov/index.php I think it was some of them who are working on the subvocalisation stuff - http://www.nasa.gov/centers/ames/news/releases/2004/subvocal/subvocal.html http://www.nasa.gov/centers/ames/news/releases/2004/subvocal... - which is basically cyborg telepathy, near as dammit.
