This topic deals with what might commonly be called ?mind reading?. More specifically and technically it deals with methods by which the thoughts a person is thinking can be inferred by analyzing physiological data obtained about that person from any sort of sensor devices. This inference need not be 100% effective to be a powerful technique for information gathering from, and harassment of a targeted individual. Even a remote heartbeat and breathing monitor, combined with surveillance cameras, would allow for thought inferences that would be extremely unnerving to a targeted person. Combining such capabilities with techniques and technologies would allow for a ?full - duplex? sort of mind manipulation..
