Futurologist Dr Ian Pearson believes a helmet placed on a human head in a laboratory will be able to project their thoughts in real-time.
He spoke after researchers claimed they can tell what rats are thinking by analysing activity in their brains.
But ex-cybernetics engineer Pearson believes humans are will be able to take it one step further.
The Futurizon blogger believes either a TV or PC screen will display human thoughts as the person is thinking them live.
Asked how far away from the technology we are, he told Daily Star Online: “I would think in a lab we’re probably a decade or 15 years away from that.”
Dr Pearson said tests analysing human brain activity have been carried out before.
Therefore he believes we’re on course for the terrifying idea of having the privacy inside our heads invaded.
